Controller specific adaption of ADC default parameters #1
Description
Different MCU types provide different ADC implementations (Analog Digital Converter).
In particular the following parameters differ between the implementations:
- V_ADC_FULLRANGE (maximum input voltage)
- N_ADC_FULLRANGE (digital readout value when input is at maximum voltage)
The following table shows the to be supported MCU types and the corresponding ADC parameters.
| MCU | V_ADC_FULLRANGE [V] | N_ADC_FULLRANGE [1] |
|---|---|---|
| ESP 8266 | 1 | 1023 |
| Adafruit Feather M0 | 3.3 | 1023 |
| Arduino DUE | 3.3 | 1023 |
| Atmel AVR | 5 | 1023 |
Tasks
