stickbreaker is already on it

@fly135: Yes - normally it works fine!
But there are several known flaws (eg i2c Write Issue #834) in the i2c implementation within esp32... and one of them is really nagging me

Aaargh cant believe how obviosly

Thanks Kolban - that makes it clear to me of course! Now I can go on and have a look why i2c seems to freeze the whole esp32 chip every now and then...

Hi folks! I am playing around with a project and i2c is just driving me nuts. I get occasional freezes of the whole ESP32 what is a show stopper. As a rookie I want to learn and try to understand what is going wrong - so I bought a cheap scope and logic analyzer. For pinning down the problems I star...

After reading more literature, I got an idea: Maybe its all that timecritic bitbanging stuff going on for the HX711 scales... - while it looks for me as its "non blocking" code it seems to trigger that watchdog...

Hi folks! I am a little desperate with my project - maybe one of you has a good pointer for me? Hardware setup: I am using a ESP32 Devkit V1 - connected GPIOs: i2c SCL 22 i2c Data 21 ACS712 sensor 39 HX711 Scale 3 SCK 35 HX711 Scale 3 DT 32 HX711 Scale 2 SCK 33 HX711 Scale 2 DT 25 HX711 Scale 1 SCK ...
