Then I put in the same code as above and my serial port went dead with the same symptoms.
Now some history.:
I wrote this a few years ago and have been updating it with improvements over time. I realize now that it probably had this problem back then but because I was doing OTA I did not realize it.
At least not until I messed up OTA leaving serial as my only option.
Now some observations:
A cold boot works, meaning the display shows me what I want to see.
But if I press the reset button the display goes white and nothing is seen.
How can I fix these two boards? One of them is a nice one with a battery and charging circuit.
Thank you.
