PWM Receiver for PR20-10

Would I be able to just use an ADC to detect the level of the PWM output or do I need a different board? My goal here is to detect the output level from a PR20-10 as part of our automated test bench.

Hi,
ADC wont be able to read it because the voltage always stays at 5V.

You will need digital inputs to read pulse signal.

Thanks

Can I get some official guidance on product selection?

Can I get some code guidance on how to record the duty cycle from for example the PCA9685 with a MCP23008? Any language is acceptable I’m just having a hard time understanding how to set the high bit and low bit and figure out the time in between.

Hi,

Here is some sample code that will run on a Particle Photon:

It essentially initializes the MCP23008 setting all DIOs to floating inputs so they can be used to monitor 0-5VDC High/Low signals. There is place holder text in there to show you where code will be triggered when input 1 goes high or low. Perhaps this will get you going in the correct direction. Ideally this code would run on a separate thread so the input could be monitored very quickly.
