WebbI want to measure a moving average of the amplitude of a fix frequency, fixed dutycyle PWM signal with slowly varying amplitude but in a noisy environment (DC motors). I want to use as little as possible CPU power to do this and have the ADC do this for me. I have an internal signal coming from a timer that is in sync with the signal to measure.
