Library Description
The library contains the functions needed to start and read the ADC values.
Key functions:
void pot2_adcInit()- ADC Init function.void pot2_adcSetInputChannel()- ADC set input channel function.uint32_t pot2_adcRead()- ADC read function.
Examples description
The application is composed of the three sections :
- System Initialization - Initializes LOG to print data that is read from ADC.
- Application Initialization - Initialization ADC Init and sets ADC input channel.
- Application Task - (code snippet) - Reads data from ADC and logs data to USBUART every 500 ms.
void applicationTask()
{
uint16_t ADC_value;
char demoText[ 50 ];
ADC_value = pot2_adcRead();
WordToHex(ADC_value, demoText);
mikrobus_logWrite(" ADC value: 0x", _LOG_TEXT);
mikrobus_logWrite(demoText, _LOG_LINE);
Delay_ms( 500 );
}

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 clickor 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.
