PWM measurements usig Raspberry and Python

Mon May 20, 2019 8:58 am

I would like to connect 3 measuring devices to Raspberry's pins BCM 12, 13 and 18. All these devices are sending PWM signal at the same time. Is it possible to measure 3 PWM signals at a time ? I would like to use python.

If the devices send one pulse per second, probably yes, if they send 100 thousand pulses per second probably no.

You need to explain what you are trying to do. At the very least we need to know the frequencies and duty cycles to expect.
