Remote Temp click

Remote Temp Click is a temperature sensing Click board™, which features the EMC1833 from Microchip, a specifically designed IC, capable of measuring remote temperature. This option makes Remote Temp click well-suited for monitoring the temperature of a CPU, GPU or FPGA, where the BJT model junction can be a substrate PNP or NPN.

Click library

• Author : MikroE Team
• Date : Dec 2019.
• Type : I2C type

Software Support

We provide a library for the RemoteTemp Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for RemoteTemp Click driver.

Standard key functions :

• Config Object Initialization function.

void remotetemp_cfg_setup ( remotetemp_cfg_t *cfg );

• Initialization function.

REMOTETEMP_RETVAL remotetemp_init ( remotetemp_t *ctx, remotetemp_cfg_t *cfg );

• Click Default Configuration function.

void remotetemp_default_cfg ( remotetemp_t *ctx );

Example key functions :

• Getting state of INT pin.

uint8_t remotetemp_int_get ( remotetemp_t *ctx );

• Getting state of AN pin.

uint8_t remotetemp_an_get ( remotetemp_t *ctx );

• Setting temperature range.

uint8_t remotetemp_set_range( remotetemp_t *ctx, uint8_t range_setting );

Examples Description

This application reads remote temperature data.

The demo application is composed of two sections :

Application Init

Initializes I2C driver, sets range, configures device and sets threshold values.

void application_init ( void )
{
    log_cfg_t log_cfg;
    remotetemp_cfg_t cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );
    
    //  Click initialization.

    remotetemp_cfg_setup( &cfg );
    REMOTETEMP_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    remotetemp_init( &remotetemp, &cfg );
    Delay_ms( 300 );
    remotetemp_set_range( &remotetemp, REMOTETEMP_RANGE_0_127 );
    remotetemp_default_cfg( &remotetemp );
    log_printf( &logger, "> app init done \r\n" );
}

Application Task

Executes all 'remotetemp_aux_getXxx()' functions.

void application_task ( void )
{
    remotetemp_aux_get_fault( &remotetemp );
    remotetemp_aux_get_high_limit_status( &remotetemp );
    remotetemp_aux_get_low_limit_status( &remotetemp );
    remotetemp_aux_get_therm_limit_status( &remotetemp );
    remotetemp_aux_get_hottest_status( &remotetemp );
    Delay_ms(500);
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.RemoteTemp

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
