Re: Measuring PWM input signals

You could try adding a capacitor on the PWM signal line to act as a low-pass filter, and then run it into an analog input.

Or you could run the PWM signal into a digital input and use change notification (interrupt on logic level change). I did this to decode a PPM signal on a PIC micro and it works great.
