Library Description

Key functions:

• uint16_t isoadc2_read_adc ( void ) - Function for reading 12bit ADC data
• uint16_t isoadc2_get_mv ( uint16_t adc_data ) - Function for converting ADC to mV data

Examples description

The application is composed of three sections :

• System Initialization - Initialization of SPI module and additional pins
• Application Initialization - Maps GPIO and SPI for selected MIKROBUS
• Application Task - Every second reads ADC data, it to mV and logs result

void application_task ( )
{
    char demo_txt[ 30 ];
    uint16_t rx_data;
    uint16_t mv_data;
    
    rx_data = isoadc2_read_adc(  );
    mv_data = isoadc2_get_mv( rx_data );
    WordToStr( rx_data, demo_txt );
    mikrobus_logWrite( " - ADC: ", _LOG_TEXT );
    mikrobus_logWrite( demo_txt, _LOG_LINE );
    WordToStr( mv_data, demo_txt );
    mikrobus_logWrite( " - VIN: ", _LOG_TEXT );
    mikrobus_logWrite( demo_txt, _LOG_TEXT );
    mikrobus_logWrite( " mV", _LOG_LINE );
    mikrobus_logWrite( "---------------", _LOG_LINE );

    Delay_ms( 1000 );
}

• SPI
• UART

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.
