-Functions

void app_init (void)
 A function you will implement to initialize your application's low- level setup. The app_init function is called after system clocks are initialized, and before anything else.
 
void app_wake_from_backup (void)
 OPTIONAL: A function you may implement to restore state after waking up from BACKUP mode on the SAM L21 or L22. This function is called after system_init, but before app_setup. You can stash a bit of your application state in the RTC's BKUP and GPn registers, and use this function as an opportinity to restore it before app_setup is called.
 
-void app_setup (void)
 A function you will implement to set up your app. The app_setup function is like setup() in Arduino. It is called once when the program begins, after app_init and app_wake_from_backup, if it exists. You should use this function to set up your application state and configure any peripherals you need to use.
 
bool app_loop (void)
 A function you will implement to serve as the app's main run loop. This method will be called repeatedly, or if you enter STANDBY mode, as soon as the device wakes from that mode.
 
-void yield (void)
 OPTIONAL: A function to yield control of the CPU to other tasks. This function is called in the delay function to allow other tasks to run while the CPU is busy waiting. By default, this function does nothing, but if you are using the USB peripheral, you should implement this function and call tud_task at minumum, along with any other USB-related tasks you need to run.

Function Documentation

◆ app_init()

- -
-
- - - - - - - - -
void app_init (void )
-
- -

A function you will implement to initialize your application's low- level setup. The app_init function is called after system clocks are initialized, and before anything else.

-

You may be wondering why there is an app_init function as well as an app_setup function. The main difference is that app_init is only meant to be callec once, at boot, whereas you might want to call app_setup multiple times, for example if you want to disable some peripherals before entering STANDBY mode, and re-enable them after waking up. In essence, you should set up anything that will run forever in app_init, whereas anything that could get turned off in the course of execution should be set up in app_setup.

Note
If your application plans to use the real-time clock perhiperal, you probably want to call the rtc_init function here.
- -
-
- -

◆ app_loop()

- -
-
- - - - - - - - -
bool app_loop (void )
-
- -

A function you will implement to serve as the app's main run loop. This method will be called repeatedly, or if you enter STANDBY mode, as soon as the device wakes from that mode.

-
Note
In order to wake from STANDBY mode, you must set up an interrupt or wake source. Otherwise your app will remain in STANDBY indefinitely.
-
Returns
true if your app is prepared to enter STANDBY mode. If you return false, your app's app_loop method will be called again immediately.
- -
-
- -

◆ app_wake_from_backup()

- -
-
- - - - - - - - -
void app_wake_from_backup (void )
-
- -

OPTIONAL: A function you may implement to restore state after waking up from BACKUP mode on the SAM L21 or L22. This function is called after system_init, but before app_setup. You can stash a bit of your application state in the RTC's BKUP and GPn registers, and use this function as an opportinity to restore it before app_setup is called.

-
Note
You do not need to implement this function unless you are using the SAM L21 or L22 and you want to restore state from BACKUP mode.

Detailed Description

-

External Interrupt Controller.

-

Function Documentation

- -

◆ eic_configure_callback()

- -
-
- - - - - - - - -
void eic_configure_callback (eic_cb_t callback)
-
- -

Configures an external interrupt callback.

-

You only get the one callback, so if you need to handle multiple interrupts, you'll need to check the EIC->INTFLAG register in your callback to determine which interrupt fired.

Parameters
- - -
callbackThe function that will be called when the interrupt fires.
-
-
-
Note
This function is called from the interrupt handler, so it should be as short as possible.
- -
-
- -

◆ eic_configure_pin()

- -
-
- - - - - - - - - - - - - - - - - - -
int8_t eic_configure_pin (const uint8_t pin,
eic_interrupt_trigger_t trigger 
)
-
- -

Configures an external interrupt on one of the external interrupt pins.

-

This function configures the interrupt channel with the specified trigger, but it does not set pin direction, mux or pull; you must set up the pin yourself. This function also does not enable an interrupt or event generation. You must call eic_enable_interrupt() or eic_enable_event() to either wake the processor or generate an event for a peripheral.

Parameters
- - - -
pinThe external interrupt pin you wish to configure — use HAL_GPIO_xxx_PIN() macro.
triggerThe condition on which you wish to trigger: rising, falling or both.
-
-
-
Returns
the EIC channel number associated with the pin, or -1 if the pin is not an interrupt pin.
-
Note
Be sure to check your pin multiplexing table to ensure that you do not have multiple pins assigned to the same interrupt channel. Also note that the NMI pin is not currently supported.
-

FIXME: Should we have macros for this that accept a port / pin?

- -
-
- -

◆ eic_disable_event()

- -
-
- - - - - - - - -
bool eic_disable_event (const uint8_t pin)
-
- -

Disables the interrupt on the given interrupt channel.

-
Parameters
- - -
pinThe external interrupt pin.
-
-
- -
-
- -

◆ eic_disable_interrupt()

- -
-
- - - - - - - - -
bool eic_disable_interrupt (const uint8_t pin)
-
- -

Disables the interrupt on the given interrupt channel.

-
Parameters
- - -
pinThe external interrupt pin.
-
-
- -
-
- -

◆ eic_enable_event()

- -
-
- - - - - - - - -
bool eic_enable_event (const uint8_t pin)
-
- -

Enables an interrupt on the given interrupt channel.

-
Parameters
- - -
pinThe external interrupt pin.
-
-
- -
-
- -

◆ eic_enable_interrupt()

- -
-
- - - - - - - - -
bool eic_enable_interrupt (const uint8_t pin)
-
- -

Enables an interrupt on the given interrupt channel.

-
Parameters
- - -
pinThe external interrupt pin.

+ + + + + + + + + + + + + + + + + +

+Functions

void app_init (void)
 A function you will implement to initialize your application's low- level setup. The app_init function is called after system clocks are initialized, and before anything else.
 
void app_wake_from_backup (void)
 OPTIONAL: A function you may implement to restore state after waking up from BACKUP mode on the SAM L21 or L22. This function is called after system_init, but before app_setup. You can stash a bit of your application state in the RTC's BKUP and GPn registers, and use this function as an opportinity to restore it before app_setup is called.
 
+void app_setup (void)
 A function you will implement to set up your app. The app_setup function is like setup() in Arduino. It is called once when the program begins, after app_init and app_wake_from_backup, if it exists. You should use this function to set up your application state and configure any peripherals you need to use.
 
bool app_loop (void)
 A function you will implement to serve as the app's main run loop. This method will be called repeatedly, or if you enter STANDBY mode, as soon as the device wakes from that mode.
 
+void yield (void)
 OPTIONAL: A function to yield control of the CPU to other tasks. This function is called in the delay function to allow other tasks to run while the CPU is busy waiting. By default, this function does nothing, but if you are using the USB peripheral, you should implement this function and call tud_task at minumum, along with any other USB-related tasks you need to run.
 
+

Detailed Description

+

This section describes the application framework that you will use to write your firmware.

+

All Gossamer applications are built by implementing the three functions described in this section. There is an optional fourth function that relates to the SAM L21 and L22's BACKUP mode, but you do not need to implement it unless you are using the BACKUP mode functionality.

+

Function Documentation

+ +

◆ app_init()

+ +
+
+ + + + + + + + +
void app_init (void )
+
+ +

A function you will implement to initialize your application's low- level setup. The app_init function is called after system clocks are initialized, and before anything else.

+

You may be wondering why there is an app_init function as well as an app_setup function. The main difference is that app_init is only meant to be callec once, at boot, whereas you might want to call app_setup multiple times, for example if you want to disable some peripherals before entering STANDBY mode, and re-enable them after waking up. In essence, you should set up anything that will run forever in app_init, whereas anything that could get turned off in the course of execution should be set up in app_setup. If your application plans to use the real-time clock perhiperal, you probably want to call the rtc_init function here.

+ +
+
+ +

◆ app_loop()

+ +
+
+ + + + + + + + +
bool app_loop (void )
+
+ +

A function you will implement to serve as the app's main run loop. This method will be called repeatedly, or if you enter STANDBY mode, as soon as the device wakes from that mode.

+
Note
In order to wake from STANDBY mode, you must set up an interrupt or wake source. Otherwise your app will remain in STANDBY indefinitely.
+
Returns
true if your app is prepared to enter STANDBY mode. If you return false, your app's app_loop method will be called again immediately.
+ +
+
+ +

◆ app_wake_from_backup()

+ +
+
+ + + + + + + + +
void app_wake_from_backup (void )
+
+ +

OPTIONAL: A function you may implement to restore state after waking up from BACKUP mode on the SAM L21 or L22. This function is called after system_init, but before app_setup. You can stash a bit of your application state in the RTC's BKUP and GPn registers, and use this function as an opportinity to restore it before app_setup is called.

+
Note
You do not need to implement this function unless you are using the SAM L21 or L22 and you want to restore state from BACKUP mode.

Detailed Description

+

Functions for configuring and using the External Interrupt Controller.

+

Function Documentation

+ +

◆ eic_configure_callback()

+ +
+
+ + + + + + + + +
void eic_configure_callback (eic_cb_t callback)
+
+ +

Configures an external interrupt callback.

+

You only get the one callback, so if you need to handle multiple interrupts, you'll need to check the EIC->INTFLAG register in your callback to determine which interrupt fired.

Parameters
+ + +
callbackThe function that will be called when the interrupt fires.
+
+
+
Note
This function is called from the interrupt handler, so it should be as short as possible.
+ +
+
+ +

◆ eic_configure_pin()

+ +
+
+ + + + + + + + + + + + + + + + + + +
int8_t eic_configure_pin (const uint8_t pin,
eic_interrupt_trigger_t trigger 
)
+
+ +

Configures an external interrupt on one of the external interrupt pins.

+

This function configures the interrupt channel with the specified trigger, but it does not set pin direction, mux or pull; you must set up the pin yourself. This function also does not enable an interrupt or event generation. You must call eic_enable_interrupt() or eic_enable_event() to either wake the processor or generate an event for a peripheral.

Parameters
+ + + +
pinThe external interrupt pin you wish to configure — use HAL_GPIO_xxx_PIN() macro.
triggerThe condition on which you wish to trigger: rising, falling or both.
+
+
+
Returns
the EIC channel number associated with the pin, or -1 if the pin is not an interrupt pin.
+
Note
Be sure to check your pin multiplexing table to ensure that you do not have multiple pins assigned to the same interrupt channel. Also note that the NMI pin is not currently supported.
+

FIXME: Should we have macros for this that accept a port / pin?

+ +
+
+ +

◆ eic_disable_event()

+ +
+
+ + + + + + + + +
bool eic_disable_event (const uint8_t pin)
+
+ +

+
+ +

◆ eic_disable_interrupt()

+ +
+
+ + + + + + + + +
bool eic_disable_interrupt (const uint8_t pin)
+
+ +

Disables the interrupt on the given interrupt channel.

+
Parameters
+ + +
pinThe external interrupt pin.
+
+
+ +
+
+ +

◆ eic_enable_event()

+ +
+
+ + + + + + + + +
bool eic_enable_event (const uint8_t pin)
+
+ +

Enables an interrupt on the given interrupt channel.

+
Parameters
+ + +
pinThe external interrupt pin.
+
+
+ +
+
+ +

◆ eic_enable_interrupt()

+ +
+
+ + + + + + + + +
bool eic_enable_interrupt (const uint8_t pin)

Detailed Description

+

Functions for configuring and using the SAM L22's Segment LCD peripheral.

+

Function Documentation

+ +

◆ slcd_clear()

+ +
+
+ + + + + + + + +
void slcd_clear (void )
+
+ +

Clears all display memory.

+

TODO: Can we optimize this? If under 32 segments, we can write 0 to just the SDATAL registers. For only 3 or 4 COMs, we can skip higher numbered registers.

+ +
+
+ +

◆ slcd_clear_segment()

+ +
+
+ + + + + + + + + + + + + + + + + + +
void slcd_clear_segment (uint8_t com,
uint8_t seg 
)
+
+ +

Clears a segment in the display memory.

+
Parameters
+ + + +
comThe common line to clear. Valid options are 0-7.
segThe segment to clear. Valid options are 0-39.
+
+
+ +
+
+ +

◆ slcd_configure_blink()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
void slcd_configure_blink (bool blink_all,
uint8_t bss0,
uint8_t bss1,
uint8_t fc 
)
+
+ +

Configures the blink mode, but does not start blinking.

+
Note
SLCD must be disabled to configure the blinking mode.
+
Parameters
+ + + + + +
blink_allIf true, all segments will blink. If false, only the segments specified in the next two masks will blink.
bss0Blink segment select 0. A 1 in any bit position (n) will cause the (COMn, SEG0) segment to blink. Ignored if blink_all is true.
bss1Blink segment select 1. A 1 in any bit position (n) will cause the (COMn, SEG1) segment to blink. Ignored if blink_all is true.
fcThe frame counter to use for blinking. Valid options are 0, 1, or 2.
+
+
+ +
+
+ +

◆ slcd_configure_circular_shift_animation()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
void slcd_configure_circular_shift_animation (uint16_t initial_value,
uint8_t size,
slcd_csrshift_value_t shift_dir,
uint8_t fc 
)
+
+ +

Configures the Circular Shift Register animation, but does not start it. This is pretty obscure and you should consult the datasheet for more information.

+
Note
SLCD must be disabled to configure the circular shift register.
+
Parameters
+ + + + + +
initial_value16 bits. The initial value of the circular shift register.
sizeThe size of the circular shift register. Valid options are 2 through 16.
shift_dirThe direction of the shift. Valid options are SLCD_CSRSHIFT_LEFT or SLCD_CSRSHIFT_RIGHT.
fcThe frame counter to use for shifting. Valid options are 0, 1, or 2.
+
+
+ +
+
+ +

◆ slcd_configure_frame_counter()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
void slcd_configure_frame_counter (uint8_t fc,
uint8_t overflow_count,
bool prescale 
)
+
+ +

Configures one of the three frame counters.

+
Note
SLCD must be disabled to configure frame counters.
+
Parameters
+ + + + +
fcThe frame counter to enable. Valid options are 0, 1, or 2.
overflow_countThe number of frames to count before the overflow fires. Maximum value is 32 frames.
prescaleIf true, the frame counter will count every 8th frame instead of every frame. This will let you count up to 256 frames in increments of 8.
+
+
+ +
+
+ +

◆ slcd_init()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
void slcd_init (uint64_t lcd_pins,
slcd_bias_value_t bias,
slcd_duty_value_t duty,
slcd_clocksource_value_t clocksource,
slcd_prescaler_value_t prescaler,
slcd_clockdiv_value_t clkdiv 
)
+
+ +

Initializes the SLCD peripheral, but does not enable it.

+

This function sets up the SLCD peripheral with some defaults:

    +
  • LCD runs in standby
    • +
  • Lowest possible contrast level (2.45 volts)
    • +
  • Uses the low power waveform
    • +
  • Charge pump refresh at 250Hz (slowest option)
    • +
  • Reference Refresh at 62.5Hz (slowest option)
    • +
  • Bias buffer enabled (side note / TODO: does turning this off save power?)
    • +
+

You will need to specify the remaining configuration options. Duty and bias are easy, but prescaler, clock divider and number of COM lines will combine to determine the frame rate of the display according to this formula: 32768/(prescaler * clock_divider * number_of_common_lines)

Parameters
+ + + + + + + +
lcd_pinsA 64-bit mask of the pins to use for the SLCD, as numbered in the pin mux table in the data sheet (SLCD/LP[n]). For example, PB08 is SLCD/LP[2] and PA05 is SLCD/LP[5], so the mask for using both of these pins would be (1 << 2) | (1 << 5). The lowest pins are always used as the common lines, so for a 1/2 duty LCD using pins 2, 5, 6, 7, 30 and 35, pins 2 and 5 would be the COM0 and COM1, and the rest would be segment lines SEG0-SEG3.
biasThe bias configuration for the SLCD. Valid options are:
    +
  • SLCD_BIAS_STATIC for a static display (0V, VLCD)
    • +
  • SLCD_BIAS_HALF for 1/2 bias (0V, 1/2 VLCD, VLCD)
    • +
  • SLCD_BIAS_THIRD for 1/3 bias (0V, 1/3 VLCD, 2/3 VLCD, VLCD)
    • +
  • SLCD_BIAS_FOURTH for 1/4 bias (0V, 1/4 VLCD, 1/2 VLCD, 3/4 VLCD, VLCD)
    • +
+
dutyThe duty cycle for the SLCD, aka the number of common lines. Valid options are:
    +
  • SLCD_DUTY_1_COMMON for a static display
    • +
  • SLCD_DUTY_2_COMMON for two common lines and a 1/2 duty cycle
    • +
  • SLCD_DUTY_3_COMMON for three common lines and a 1/3 duty cycle
    • +
  • SLCD_DUTY_4_COMMON for four common lines and a 1/4 duty cycle
    • +
  • SLCD_DUTY_6_COMMON for six common lines and a 1/6 duty cycle
    • +
  • SLCD_DUTY_8_COMMON for eight common lines and a 1/8 duty cycle
    • +
+
clocksourceThe clock source for the SLCD. Valid options are:
    +
  • SLCD_CLOCKSOURCE_ULP for the low-accuracy, low-power internal 32kHz oscillator
    • +
  • SLCD_CLOCKSOURCE_XOSC for an external 32kHz crystal oscillator
    • +
+
prescalerThe prescaler factor, which initially divides the 32kHz clock. Valid options are:
    +
  • SLCD_CTRLA_PRESC_PRESC16_Val - Divide by 16
    • +
  • SLCD_CTRLA_PRESC_PRESC32_Val - Divide by 32
    • +
  • SLCD_CTRLA_PRESC_PRESC64_Val - Divide by 64
    • +
  • SLCD_CTRLA_PRESC_PRESC128_Val - Divide by 128
    • +
+
clock_dividerThe clock divider, which divides the prescaled clock. Valid options areL
    +
  • SLCD_CLOCKDIV_1 for no division
    • +
  • SLCD_CLOCKDIV_2 to divide by 2
    • +
  • SLCD_CLOCKDIV_3 to divide by 3
    • +
  • SLCD_CLOCKDIV_4 to divide by 4
    • +
  • SLCD_CLOCKDIV_5 to divide by 5
    • +
  • SLCD_CLOCKDIV_6 to divide by 6
    • +
  • SLCD_CLOCKDIV_7 to divide by 7

Detailed Description

+

Functions for configuring the system and putting it in standby mode.

+

Function Documentation

+ +

◆ _enable_48mhz_gclk1()

+ +
+
+ + + + + + + + +
void _enable_48mhz_gclk1 (void )
+
+ +

Enables the 48 MHz clock on GCLK1 for USB operation.

+

This function is called by the USB stack when it is initialized.

Warning
At this time, the 48 MHz clock is hard-coded to use USB Clock Recovery Mode, and as such will only be available if your device is plugged into a USB host. It is possible to derive the 48 MHz DFLL from an external 32kHz crystal, but this is not currently implemented in Gossamer.
+ +
+
+ +

◆ _enter_standby_mode()

+ +
+
+ + + + + + + + +
void _enter_standby_mode (void )
+
+ +

Enters the low-power STANDBY mode. Does not return until an interrupt fires.

+

You should not generally need to call this function; at the end of every app_loop invocation, the main run loop enters standby mode if your app indicated that it was appropriate.

+ +
+
+ +

◆ get_cpu_frequency()

+ +
+
+ + + + + + + + +
uint32_t get_cpu_frequency (void )
+
+ +

Gets the CPU frequency.

+
Returns
8000000 by default, or another value if set by set_cpu_frequency
+ +
+
+ +

◆ set_cpu_frequency()

+ +
+
+ + + + + + + + +
bool set_cpu_frequency (uint32_t freq)
+
+ +

Sets the CPU frequency.

+
Parameters
+ + +
freqone of 1000000, 2000000, 4000000, 8000000, 12000000 or 16000000.
+
+
+

Supported CPU frequencies vary from chip to chip:

    +
  • On the SAM D11 and D21, you can choose 8, 4, 2 or 1 MHz.
    • +
  • On the SAM L21 and L22, you can choose 16, 12, 8 or 4 MHz. While you can run these chips at higher frequencies using the DFLL, Gossamer aims for simplicity: this means that it only supports the internal oscillator at one of its standard frequencies.
    Note
    Some peripherals like SERCOMs and TC/TCCs read the CPU frequency when they are configured, to set critical timing-related parameters like baud rate or period. If you change the CPU frequency after setting up these peripherals and then attempt to use them, they will very likely behave in unexpected ways. Thus you should de-init any peripherals that depend on GCLK0 before calling set_cpu_frequency, and then re-init them after.
    +
    • +
+ +
+
+ +

◆ sys_init()

+ +
+
+ + + + + + + + +
void sys_init (void )
+
+ +

Initializes the system clocks and performs any required system-wide setup.

+

Gossamer aims for consistency at system startup, no matter which chip you are working with. To that end:

    +
  • GCLK0, the main system clock, is set to 8 MHz.
    • +
  • GCLK2 is the low-power 32768 Hz clock, OSCULP32K
    • +
  • GCLK3 is a 1024 Hz clock, derived from the most accurate source available. GCLK0 is set to ONDEMAND with RUNSTDBY off, so the main clock remains off when in standby mode. GCLK2 and GCLK3 are also ONDEMAND, but RUNSTDBY is on. This ensures that if a peripheral requests it, the clock will remain on in standby, but if no peripheral requests it, it will not run at all. Also note that while GCLK1 is not turned on at startup, it may be reserved for internal use depending on your use case. If you intend to use USB, the usb_init function will claim GCLK1 for the 48 MHz DFLL clock.

Detailed Description

-

UART Peripheral.

-

The UART peripheral is used for serial communication over TX and RX pins. Note that Gossaermer's UART implementation is interrupt-driven, which is different from the SPI and I2C peripherals. If you want to use the UART, you MUST implement the following function, replacing 'N' with the SERCOM number you are using: void irq_handler_sercomN(void) { uart_irq_handler(N); } This interrupt handler will allow the UART to buffer incoming data to a FIFO, which is what you're actually reading from when you call uart_read.

Warning
If you don't implement the interrupt handler, your application will hang, and you'll be confused until you read this line! (or in my case, write it)

Detailed Description

+

Functions for configuring and using the USB peripheral.

+

Gossamer uses the TinyUSB stack for USB support.

+

Function Documentation

+ +

◆ usb_disable()

+ +
+
+ + + + + + + + +
void usb_disable (void )
+
+ +

Disables the USB peripheral.

+
Note
Has not been extensively tested, TinyUSB may not like this.
+ +
+
+ +

◆ usb_enable()

+ +
+
+ + + + + + + + +
void usb_enable (void )
+
+ +

Initializes the TinyUSB stack and enables the USB peripheral.

+

In order to make use of the tinyUSB stack, there are two additional setup steps you must take:

    +
  1. In your Makefile, set the type and number of TinyUSB device classes you intend to use. For example, if you want to use a USB mass storage class, you would add TINYUSB_MSC=1 to your app's Makefile. You can also add more than one class, e.g. for two CDC interfaces, you would add TINYUSB_CDC=2. Available TinyUSB classes are:
      +
    • TINYUSB_CDC
      • +
    • TINYUSB_MSC
      • +
    • TINYUSB_HID
      • +
    • TINYUSB_MIDI
      • +
    • TINYUSB_VENDOR
      • +
    +
    2. +
  2. You must also set up your USB device descriptor. This is typically done in a usb_descriptors.c file. See the usb app for an example of how to do this.
    3. +
  3. Depending on which classes you enable, you may need to do some additional setup. Check out tinyusb's examples for more info.
    4. +
+ +
+
+ +

◆ usb_is_enabled()

+ +
+
+ + + + + + + + +
bool usb_is_enabled (void )
+
+ +

Checks if the USB peripheral is enabled.

+
Returns
true if the USB peripheral is enabled, false otherwise.

-gossamer: a very lightweight firmware framework for SAMD and SAML chips

-

Gossamer is an extremely lightweight framework for developing bare-metal firmware applications for the Microchip SAM D and SAM L series chips. It aims for consistency, simplicity and low power consumption.

-

Gossamer targets four chips at this time: the SAM D11, D21, L21 and L22. These chips are all strikingly similar: they all have Cortex M0+ cores as well as native USB and as familiar peripherals like ADC's, TCC's and SERCOMs. Alas, a lot of the interfaces to these peripherals have slight differences, and at startup, these chips have subtly different clock setups.

-

The primary goal of the project is to provide a simple environment for writing firmware for these chips. The secondary goal is to ensure that the code you write will be compatible across chips in the family. By papering over subtle differences in syntax and setup, you should be able to write code for one chip in the family (like the SAM D21), and then seamlessly compile it for another, like the SAM D11 if you realize you need to cut BOM costs, or the L21 if you decide that low power is your priority.

-

Not all devices have all the same peripherals. Some features, like the segment LCD, are specific to one chip like the SAM L22. Even some devices that do have the same peripherals have different configuration options; for example, the DAC peripheral has two 12-bit channels on the SAM L21, but only one 10-bit channel on the SAM D21 and D11. Still, many of the peripherals are very similar on the different platforms, and gossamer provides a thin layer of translation on top that should make it easy to move up and down the product line.

-

-Clock Tree

-

If you look at the data sheets for these chips, you'll see that some boot with a 1 MHz clock, and others with a 4 MHz clock. No generic clocks are defined, and if you're coming from the Atmel Start world, you'll recall that it was on you to invent a clock tree from sceatch.

-

Gossamer simplifies this by giving you a consistent environment on all four platforms:

+

Gossamer is an extremely lightweight framework for developing bare-metal firmware applications for the Microchip SAM D and SAM L series chips. Before you get started, you might want to take a look at the README.

+

After that, you can get a sense for how to implement an app with the Gossamer application framework.

+

You'll also want to know some stuff about the System Internals.

+

From there, check out all the peripherals available on most chips:

-

Some peripherals are automatically clocked from the source that makes the most sense (i.e. RTC from GCLK3, EIC from GCLK2). SERCOM peripherals are clocked from the main clock, but provide a configurable baud rate in their init functions. More versatile peripherals like the TC and TCC take a generic clock and prescaler factor as parameters in their init functions.

-

-Application Framework

-

Much like an Arduino sketch has setup and loop functions, a Gossamer application is implemented in three functions:

+

There are also special peripherals that are only available on certain chips:

    -
  • app_init is called after the system clocks are initialized, and before anything else. This is an opportunity to change any low-level defaults like processor speed, and configure any additional system clocks and long-running peripherals like the RTC.
    • -
  • app_setup is akin to the Arduino setup() function, and provides an opportunity to set up your application's initial state.
    • -
  • app_loop is akin to the Arduino loop() function, with the difference that your application will return a boolean value indicating whether the application is prepared to enter STANDBY mode:
      -
    • Returning false here ensures that your app_loop will be called again immediately.
      • -
    • Returning true will send the microcontroller into STANDBY mode, where it will remain until woken by an interrupt.
      • +
    • The Segment LCD driver on the SAM L22
      • +
    • The Operational Amplifier on the SAM L21
    -
    • -
-

This last bit — entering standby mode as often as possible — is a key feature of gossamer. In standby mode, the CPU is halted, but peripherals set up to run in standby can still run, and wake the device on an interrupt like a button press, timer tick or even the receipt of data over a UART.

-

This is a great way to conserve energy in battery-powered applications, and gossamer makes it easy.

-

-Peripheral Interface

-

Peripherals are generally thin wrappers around raw register reads and writes, with little more than synchronization logic tacked on. Wrapping the raw register twiddling in function calls allows us to paper over subtle implementation details and hand-wave away register layout differences, like the difference between waiting on STATUS.bit.SYNCBUSY vs SYNCBUSY.reg. This provides a consistent way to enable, disable and operate peripherals:

-
    -
  • peripheral_init enables the peripheral clocks and configures the peripheral, but does not enable it. Generally returns void, but for peripherals whose initialization can fail (i.e. due to a bad parameter), some init functions will return a boolean value: true if successful, false otherwise.
    • -
  • peripheral_enable enables the peripheral (usually a CTRLA.bit.ENABLE, with associated SYNCBUSY wait). Some peripherals have multiple channels (DAC) or instances (SERCOM). In these cases, the enable function takes as a parameter which instance to enable.
    • -
  • peripheral_disable disables the peripheral.
      -
    • For peripherals with multiple channels, this disables the channel, unless all channels are disabled in which case it disables the whole peripheral.
      • -
    • For peripherals with multiple instances, this only disables the specified instance.
      • -
    -
    • -
-

For example, this is how you might set up the RTC peripheral, which has predefined clock defaults:

-
rtc_init();
-
rtc_enable();
-
rtc_enable
void rtc_enable(void)
Enables the RTC.
Definition rtc.c:73
-
rtc_init
void rtc_init(void)
Initializes the RTC.
Definition rtc.c:49
-

This is how you might output an analog value on DAC channel 0 (the first DAC on the SAM L21, or the only DAC on D21):

-
HAL_GPIO_A0_pmuxen(HAL_GPIO_PMUX_DAC);
-
dac_init();
-
dac_enable(0);
-
dac_set_analog_value(0, 512);
-
dac_enable
void dac_enable(dac_channel_mask_t channelmask)
Enables the DAC channels specified in the mask, and disables others.
Definition dac.c:75
-
dac_set_analog_value
void dac_set_analog_value(uint16_t channel, uint16_t value)
Set the analog value of the DAC.
Definition dac.c:97
-
dac_init
void dac_init(void)
Initializes the DAC peripheral, but does not enable it.
Definition dac.c:40
-

This is how you would set up Timer/Counter TC1 to overflow at 500 Hz (i.e. for driving a DMA transaction):

-
tc_init(1, GENERIC_CLOCK_0, TC_PRESCALER_DIV256); // 8 MHz / 256 = 125,000
-
tc_set_counter_mode(1, TC_COUNTER_MODE_8BIT)
-
tc_set_wavegen(1, TC_WAVE_WAVEGEN_MFRQ); // Match frequency mode, overflow at CC0
-
tc_count8_set_cc(1, 0, 250); // 125,000 / 250 = 500 Hz
-
tc_enable(1);
-
tc_init
bool tc_init(uint8_t instance, generic_clock_generator_t clocksource, tc_prescaler_value_t prescaler)
Enables the peripheral clock for the TC and clocks it with the selected clock source....
Definition tc.c:36
-
tc_enable
void tc_enable(uint8_t instance)
Enables the TC. Make sure to call tc_init first to set it up.
Definition tc.c:105
-
tc_count8_set_cc
void tc_count8_set_cc(uint8_t instance, uint8_t channel, uint8_t value)
Sets the TC's compare channel CC0 or CC1 register in 8-bit mode.
Definition tc.c:122
-
tc_set_counter_mode
void tc_set_counter_mode(uint8_t instance, tc_counter_mode_t mode)
Sets the TC's counting mode (an 8, 16 or 32-bit counter),.
Definition tc.c:70
-
tc_set_wavegen
void tc_set_wavegen(uint8_t instance, tc_wavegen_t mode)
Sets the TC's waveform generation mode.
Definition tc.c:78
-

For SERCOM peripherals, which have several instances, we provide a shortcut: if your board defines a I2C_SERCOM, SPI_SERCOM, or UART_SERCOM in its pins.h, you can use the i2c_init, spi_init, or uart_init functions without specifying the SERCOM instance. For example, if your board defines a I2C_SERCOM, you would set up the I2C peripheral like this:

-
HAL_GPIO_SDA_pmuxen(HAL_GPIO_PMUX_SERCOM);
-
HAL_GPIO_SCL_pmuxen(HAL_GPIO_PMUX_SERCOM);
-
i2c_init();
-
i2c_enable();
-
i2c_init
void i2c_init(void)
Initializes the I2C peripheral for a board with a defined I2C_SERCOM.
-
i2c_enable
void i2c_enable(void)
Enables the I2C peripheral for a board with a defined I2C_SERCOM.
-

However, if your board does not define I2C_SERCOM, you would use the i2c_init_instance function instead:

-
HAL_GPIO_SDA_pmuxen(HAL_GPIO_PMUX_SERCOM);
-
HAL_GPIO_SCL_pmuxen(HAL_GPIO_PMUX_SERCOM);
-
i2c_init_instance(2);
-
i2c_enable();
-
i2c_init_instance
void i2c_init_instance(uint8_t sercom, uint32_t baud)
Initializes an I2C peripheral on the given SERCOM.
Definition i2c.c:44
-

SPI_SERCOM and UART_SERCOM work similarly, although you will also need to specify SPI_SERCOM_DOPO and SPI_SERCOM_DIPO, or UART_SERCOM_TXPO and UART_SERCOM_RXPO to give Gossamer a hint at your pinout.

-

-Flashing Firmware

-

Gossamer is designed to work with Adafruit's UF2 bootloader on SAM D21, L21 and L22 chips. For SAM D11 chips, it's designed to work with the DFU bootloader. The UF2 bootloader is a drag-and-drop bootloader that presents itself as a USB drive, while the DFU bootloader is a USB DFU bootloader that can be flashed using the dfu-util command line tool.

-

Either way, gossamer papers over the differences: with a device in bootloader mode plugged in via USB, running make && make install builds your application and flashes it to a device.

-

-Emscripten Support

-

Gossamer includes a set of "dummy" peripherals that allow your application to compile to WebAssembly using Emscripten. Note that other than the GPIO macros tracking basic pin levels, these peripherals don't actually do anything, but this is an area of interest for future development.

-

-Examples

-

Boards are defined in the /boards directory, which sets up the target as well as predefined macros for all the pins on a given board. So, for example, this is how you get to blinky on any board with a built in LED:

-
#include "app.h"
-
#include "delay.h"
-
-
void app_init(void) {
-
}
-
-
void app_setup(void) {
-
HAL_GPIO_LED_out();
-
}
-
-
bool app_loop(void) {
-
HAL_GPIO_LED_toggle();
-
delay_ms(500);
-
return false;
-
}
-
app.h
Gossamer application framework.
-
app_setup
void app_setup(void)
A function you will implement to set up your app. The app_setup function is like setup() in Arduino....
-
app_loop

-
app_init
void app_init(void)
A function you will implement to initialize your application's low- level setup. The app_init functio...
-
delay.h
Delay routines.
-

A more complex app, which displays "Hello" on an Oddly Specific LCD, makes use of the pin mux assignment macros and the I2C peripheral:

-
#include "app.h"
-
#include "i2c.h"
-
#include "drivers/oso_lcd.h"
-
-
void app_init(void) {
-
}
-
-
void app_setup(void) {
-
// I2C pin mux
-
HAL_GPIO_SDA_pmuxen(HAL_GPIO_PMUX_SERCOM);
-
HAL_GPIO_SCL_pmuxen(HAL_GPIO_PMUX_SERCOM);
-
// initialize the I2C peripheral
-
i2c_init();
-
i2c_enable();
-
-
// display text on the LCD
-
oso_lcd_begin();
-
oso_lcd_fill(0);
-
oso_lcd_print("hello");
-
}
-
-
bool app_loop(void) {
-
return true;
-
}
-
i2c.h
I2C Peripheral.
-

-Current state and future plans

-

Gossamer is now stable enough for folks to use; in fact, it's the framework underlying Second Movement, the new firmware for Sensor Watch. Having said that, not all peripherals are implemented, and not all of the ones that are implemented are complete. There are lots of features for which we don't have functions defined, and certain peripherals are only implemented on certain chips.

    +
  • GCLK0, the main system clock, is set to 8 MHz at boot. You can change this in app_init using the set_cpu_frequency function.
    • +
  • GCLK1 is reserved for the 48 MHz DFLL clock, which is only configured if the USB peripheral is enabled.
    • +
  • GCLK2 is a low-power, low-accuracy 32 kHz clock sourced from OSCULP32K.
    • +
  • GCLK3 is a 1024 Hz clock, derived from the most accurate source available.
    • +

Having said that, not all peripherals are implemented, and not all of the ones that are implemented are complete. There are lots of features for which we don't have functions defined, and certain peripherals are only implemented on certain chips.

But hey: pull requests are welcome!

    ◆ _enable_48mhz_gclk1()

    - -
    -
    - - - - - - - - -
    void _enable_48mhz_gclk1 (void )
    -
    - -

    Enables the 48 MHz clock on GCLK1 for USB operation.

    -

    This function is called by the USB stack when it is initialized.

    Warning
    At this time, the 48 MHz clock is hard-coded to use USB Clock Recovery Mode, and as such will only be available if your device is plugged into a USB host. It is possible to derive the 48 MHz DFLL from an external 32kHz crystal, but this is not currently implemented in Gossamer.
    - -
    -
    - -

    ◆ _enter_standby_mode()

    - -
    -
    - - - - - - - - -
    void _enter_standby_mode (void )
    -
    - -

    Enters the low-power STANDBY mode. Does not return until an interrupt fires.

    -

    You should not generally need to call this function; at the end of every app_loop invocation, the main run loop enters standby mode if your app indicated that it was appropriate.

    - -
    -
    - -

    ◆ get_cpu_frequency()

    - -
    -
    - - - - - - - - -
    uint32_t get_cpu_frequency (void )
    -
    - -

    Gets the CPU frequency.

    -
    Returns
    8000000 by default, or another value if set by set_cpu_frequency
    - -
    -
    - -

    ◆ set_cpu_frequency()

    - -
    -
    - - - - - - - - -
    bool set_cpu_frequency (uint32_t freq)
    -
    - -

    Sets the CPU frequency.

    -
    Parameters
    - - -
    freqone of 1000000, 2000000, 4000000, 8000000, 12000000 or 16000000.
    -
    -
    -

    Supported CPU frequencies vary from chip to chip:

      -
    • On the SAM D11 and D21, you can choose 8, 4, 2 or 1 MHz.
      • -
    • On the SAM L21 and L22, you can choose 16, 12, 8 or 4 MHz. While you can run these chips at higher frequencies using the DFLL, Gossamer aims for simplicity: this means that it only supports the internal oscillator at one of its standard frequencies.
      Note
      Some peripherals like SERCOMs and TC/TCCs read the CPU frequency when they are configured, to set critical timing-related parameters like baud rate or period. If you change the CPU frequency after setting up these peripherals and then attempt to use them, they will very likely behave in unexpected ways. Thus you should de-init any peripherals that depend on GCLK0 before calling set_cpu_frequency, and then re-init them after.
      -

    -
    - -

    ◆ sys_init()

    - -
    -
    - - - - - - - - -
    void sys_init (void )
    -
    - -

    Initializes the system clocks and performs any required system-wide setup.

    -

    Gossamer aims for consistency at system startup, no matter which chip you are working with. To that end:

      -
    • GCLK0, the main system clock, is set to 8 MHz.
      • -
    • GCLK2 is the low-power 32768 Hz clock, OSCULP32K
      • -
    • GCLK3 is a 1024 Hz clock, derived from the most accurate source available. GCLK0 is set to ONDEMAND with RUNSTDBY off, so the main clock remains off when in standby mode. GCLK2 and GCLK3 are also ONDEMAND, but RUNSTDBY is on. This ensures that if a peripheral requests it, the clock will remain on in standby, but if no peripheral requests it, it will not run at all. Also note that while GCLK1 is not turned on at startup, it may be reserved for internal use depending on your use case. If you intend to use USB, the usb_init function will claim GCLK1 for the 48 MHz DFLL clock.
