Description¶
The potentiometer is connected to the internal ADC 2 channel 13.
Measurement values¶
The following diagram shows what turn direction of the potentiometer leads to a increase or decrease of voltage at the ADC.
Usage¶
Using the read only ADCPotentiometer the value can be read. The functions delivers the value transformed to an interval between 0 and 1.
// Read the potentiometer value
float adcValue = yggdrasil_ADC_Read(ADCPotentiometer);
// Read the potentiometer value
auto adcValue = bsp::ADCPotentiometer;
This value can be multiplied with the reference voltage (3.3V) or for example with 100 to get the rotation in %.
