Library Description

The library covers all the necessary functions that enables the usage of the ADC 2 click board.
It initializes and defines the SPI driver and drivers that offer functions for reading digital data
and for checking overflow states.

Key functions:

• uint32_t adc2_adcValueRead(); -  Function is used to read specific data from ADC convertor.
• uint8_t adc2_checkOverLow();-   Function is used to check overflow low state.
• uint8_t adc2_checkOverHigh(); -   Function is used to check overflow high state.

Examples Description

The application is composed of three sections:

• System Initialization - Initializes SPI module, LOG structure, sets CS pin as output.
• Application Initialization - Initalizes SPI driver and makes an initial log.
• Application Task - (code snippet) This is an example that shows the capabilities of the ADC 2 click by reading ad conversion.

void applicationTask()
{
    adcVal = adc2_adcValueRead();
    
    LongToStr( adcVal, logTxt );
    Ltrim( logTxt );
    mikrobus_logWrite( "Value : ", _LOG_TEXT );
    mikrobus_logWrite( logTxt, _LOG_LINE );
    mikrobus_logWrite( "------------------", _LOG_LINE );
    Delay_ms( 1000 );
}  

Other mikroE Libraries used in the example:

• SPI
• UART
• Conversions

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
