Arduino mega quit displaying to my adafruit screen.
I was using digital pin 9 with a fade sketch and was having issue.
I went back to working on my display and I now have no display output.
I've tryed all the different display sketchs that used to work.
How can I tell if I might have fryed a circuit?
Can I just Set the pins to high and check voltage or can I run a continuity test?
Thanks for the help.
