ESP8266 + NeoMatrix w/ SoftAP
Posted: Sun Oct 18, 2020 2:22 amI'm making a program that can dynamically push text or color or brightness to a neopixel matrix. This code works, but after about 5min the ESP8266 resets all of a sudden with no reason. Also, unrelated, I can't access the serial monitor for anything.
