Dear @agentKrowka,
thanks for writing in. While I’m not a hardware guy, it somehow dragged me into the topic of the HX711 so I’ve been able to gain a reasonable overview over possible obstacles over the course of the last years.
While things like
- Stromversorgung HX711
- Probleme Einbindung HX711 (und Stalker)
- Note/Todo: We are currently compiling a more thorough list already.
might be relevant here, your note
specifically sparked my interest: TommiPio is doing similar things like you at NodeMCU + HX711 + 4 50kgs Load Cells Returns "-83388608" · Issue #132 · bogde/HX711 · GitHub and he is getting readings constantly yielding different infamous values: -8388608 / 8388607:
the serial monitor just reports “-8388608” or “8388607” as value
There are also some comments already which seem to contain reasonable advices which might help you to solve this issue. Please also note that we should finally start to look into interrupt-driven reading as outlined in Modern libraries for reading the HX711 ADC - #4 by Andreas ff.
Good luck!
With kind regards,
Andreas.
