Avr::Adc

class Avr::Adc

A C++ wrapper for accessing the built-in 10 bit Analog to Digital Conversion (ADC) facilities.

Note

Avr::Adc is currently limited to ADC mode Single Conversion.

The prescaler is automatically configured to the lowest possible value targeting a sample rate between 50 and 200 kHz for a good compromise between performance and accuracy.
