ADC 6 click

ADC 6 click is an advanced 24bit multichannel analog to digital converter (ADC), with 8 fully differential or 15 single ended/pseudo differential sampling inputs, and very flexible routing capabilities. The click board� has two 2x10 pin headers, used both to configure the device and connect the input channels.

Click library

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

Software Support

We provide a library for the ADC6 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 ADC6 Click driver.

Standard key functions :

• Config Object Initialization function.

void adc6_cfg_setup ( adc6_cfg_t *cfg );

• Initialization function.

ADC6_RETVAL adc6_init ( adc6_t *ctx, adc6_cfg_t *cfg );

Example key functions :

• This function writes data to determined register.

void adc6_write_reg( adc6_t* ctx, const uint8_t register_address, const uint32_t transfer_data );

• This function reads data from determined register.

uint32_t adc6_read_reg(adc6_t* ctx, const uint8_t register_address);

• This function continuously reads data from Data register without writing anything on SPI.

uint32_t adc6_continuous_read_data(adc6_t* ctx);

Examples Description

This example collects data from the sensor, calculates the voltage to a digital value and then logs it.

The demo application is composed of two sections :

Application Init

Initializes driver and sets configuration witch enables apointed channel.

void application_init ( void )
{
    log_cfg_t log_cfg;
    adc6_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.

    adc6_cfg_setup( &cfg );
    ADC6_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    adc6_init( &adc6, &cfg );
    adc6_default_cfg( &adc6 );

}
  

Application Task

Gets 24-bit converted data in single read mode and logs data on terminal every 500 ms.

void application_task ( void )
{
    uint32_t adc_value = 0;

    adc_value = adc6_get_adc_data( &adc6, ADC6_SINGLE_GET_DATA_MODE );

    log_printf( &logger, "The ADC value is: %lu\r\n", adc_value );

    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.ADC6

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.
