Watchdog ESP8266 at random times HELP.
Posted: Mon Dec 26, 2022 7:17 pmHi Mates
I'm quite new to the esp8266 and the microcontroller world and its quite fun even tho it can be a bit frustrating.
I am currently developing a simple programm that goes to coingecko api and gets the crypto historic prices to draw a chart on a TFT display using the tft_espi library.
Everything is working great however, watchdog keeps resetting my esp at random times(always when preforming the same http.get) but at different times(Dont think its memory as i'm checking that).
Things i tried:
[*]Add yield() everywhere(or just in front of places that take long)
[*]Changed the cable
[*]changed the esp8266(i changed it twice)
[*]I'm constantly checking free heap memory to make sure i'm not running out.
Anyone got any suggestions?
Dont be surprised by the amount of Serial.println() in the code i rly tried to find the place where it dies.
Stack trace decoded including last few serial.println that show improtant info:
