Detecting varying PWM states

[colonelbf]

@Klaus_K

• If you have an ADC available you can turn the signal into an analog signal using a simple RC-filter.
• If you have a timer/counter with external input you can use that to detect the PWM signa

Thanks that would work but I was trying to avoid extra hardware as my project is already a bit cramped. Also I'm not quite sure how to design an RC filter that would give me clean enough analog output and I'm stuck having poll the signal still.
