ISO ADC 2 Click

ISO ADC 2 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

This is an example that demonstrates the use of the ISO ADC 2 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.IsoAdc2

Example Key Functions

• isoadc2_cfg_setup Config Object Initialization function.

void isoadc2_cfg_setup ( isoadc2_cfg_t *cfg );

• isoadc2_init Initialization function.

err_t isoadc2_init ( isoadc2_t *ctx, isoadc2_cfg_t *cfg );

• isoadc2_read_adc ISO ADC 2 ADC data reading function.

err_t isoadc2_read_adc ( isoadc2_t *ctx, uint16_t *adc_val );

• isoadc2_get_mv ISO ADC 2 voltage data reading function.

err_t isoadc2_get_mv ( isoadc2_t *ctx, uint16_t *voltage );

Application Init

Initialization of SPI module and additional GPIO pins.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    isoadc2_cfg_t isoadc2_cfg;  /**< Click config object. */

    /** 
     * 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.

    isoadc2_cfg_setup( &isoadc2_cfg );
    ISOADC2_MAP_MIKROBUS( isoadc2_cfg, MIKROBUS_1 );
    err_t init_flag  = isoadc2_init( &isoadc2, &isoadc2_cfg );
    if ( SPI_MASTER_ERROR == init_flag ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }
    log_info( &logger, " Application Task " );
}

Application Task

Every second reads ADC data and voltage in mV and logs result.

void application_task ( void ) 
{
    uint16_t rx_data;
    uint16_t mv_data;
    
    isoadc2_read_adc( &isoadc2, &rx_data );
    Delay_ms ( 100 );
    isoadc2_get_mv( &isoadc2, &mv_data );
    
    log_printf( &logger, " ADC: %d \r\n", rx_data );
    log_printf( &logger, " VIN: %d mV\r\n", mv_data );
    log_printf( &logger, "---------------\r\n" );

    Delay_ms ( 1000 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
