Weird characters shows randomly in serial #1626
Description
Hardware:
Board: Nodemcu v1.1
Core Installation/update date: 9/jul/2018
IDE name: Arduino IDE
Flash Frequency: 80Mhz
Upload Speed: 921600
Description:
I use esp32 that runs relays via shift register(74hc595) relays runs AC load , so i made a rtos software , and i have problem that run randomly so in middle or start of program i get randomly characters on serial and software freeze , and characters just keep writing in serial . Only way i can repair it is to press reset button manually but it comes again in some time . Can it be cause i power 74hc595 with 5v and controll it with esp32 wich is 3.3v ?, but all pins is output in that case.
I tried other esp32 module /no success
I tried also to put all tasks on one core / no success
I tried raw code just to turn on and off relays / no success still problem
