Could anyone provide some insight as to what might be happening here? I don't know why it's cutting off early.Ĭode: Select all | TOGGLE FULL SIZE // Wake Trinket via WDT and check for capacitive touch activation, if activated play sound and return to sleep mode. I know its a bit involved, but it's similar/an extension to the Trinket Audio player tutorial. When the sound is done playing, reset the timers to initial settings from ISR.Įverything appears to be working correctly except the sound only plays for 30-50ms, it should be ~300ms. (first set up timers for playing sound via fast-PWM method.)ĥ. Could you possibly provide some insight as to what might be happening? The sketch should do the following:ģ. However, my sketch doesn't do this correctly.
Thanks, I found out what the initial settings are for the timers (I think) so I can switch the timers between modes.

In the code below, I have found the LED flashes at 0.5Hz if no timers are on as expected. I thought there should be no effect on loop() or Arduino commands as long as Timer0 pre-scaler was not changed.
