Pulseio makes the Matrix Portal display blink continuously

by diegomoises1 on Thu Nov 12, 2020 1:12 am

I am trying to get an IR code into my matrix portal, but as soon as I declare a Pulseio object the display starts blinking. Everything works great but obviously I don't want my display to be constantly blinking. This happens in the Repl too so it has nothing to do with any other code on my part, I have tried A1 through A4 and no matter what I put into PulseIn the display starts blinking. Does the Pulseio library somehow use other pins that interrupt the matrixportal somewhere?

Something I forgot, I have tried using deinit() and with but neither do anything for the display

Would you mind filing an issue here? https://github.com/adafruit/circuitpython/issues/new

Sounds like we need to make sure both can work concurrently. They both use timers under the hood and may be conflicting.
