Library Description
The library contains functions with reading values ​​from the ADC and setting the potentiometer over the I2C lines. The values returned by MIC 2 click, the user can see on the Serial plot.
Key functions:
void mic2_setPotentiometer(uint8_t ptt_value) - Functions for sets resistance of the potentiometer.uint32_t mic2_adcRead() - ADC read.void mic2_adcSetInputChannel() - ADC set channel.void mic2_adcInit() - ADC init.Examples description
The application is composed of the three sections :
void applicationTask( )
{
uint16_t adcValue;
adcValue = mic2_adcRead();
plotData( adcValue );
}
