2 Itsy Bitsy boards not responding

Post by K212 »

Hi,
I have 2 itsy bitsy boards (5V 16Mhz), that were connected in serial and had an LCD display each. Been working fine for several months now, but today all of the sudden, the LCDs started glitching and since then I've been unable to upload new sketches.

Are they fried? I've had them for at least one year, didn't do anything different...

Tried using the reset button, but that didn't help. Double tapping it turns on an orange LED but still can't upload after that. Either it starts and then resets the com port (sometimes even not selectable), or just hangs. Tried with another USB cable too.

Didn't smell burnt or anything...

Nvm, fixed it following the steps from Ack "I did something" from here;

My code has some pointers that I believe are crashing the program, which caused the board to not respond.
