I have a teensy 3.2 connected to the audio board. Everything was working fine - playing wav files with the program "...Do_More_While_Playing".
I then added code to read pwm signals(5V) from an RC receiver using pins 3,4,5 and ground. As best I could tell the audio board does not use these pins. Worked for a few minutes and then sound went to continuous hum.
Restarted, now get the message- "Unable to access the SD card". Tried another SD card. Same thing. Can anyone tell me if using pins 3,4,5 could have fried part of the audio board, or did I just get a bad board with a 5 minute life span?
Thanks...
