I just need to detect the presence of a "Skye"signal to initiate an action. I does not matter what button. Interrupt does not seem to work (the sky signal is a falling waveform). Pulsin should work but I don't know how to read the pulses. Can anyone help? By the way, I can see the waveform on my storage scope.
