My build (very slowly progressing)

@czahl We have never updated the firmware, we use the same one as the original mystat paper. Errors when saving calibration are often related with the calibration parameters being of the incorrect numerical type or the values being too large. There might be a bug in the UI around this. I'll check when I'm back from my traveling, however I dont remember having issues saving these values when calibrating successfully with the 1k ohm resistors.

Are we talking about the same mystat repo? Again in my understanding this paper reflects the PCB from PcbWay, und this has the 4 reed relais (on top of the picture) for the 4 current ranges. In the main.c only the original 3 are handled.
Somewhere there is a mismatch, or am I'm looking into the wrong repo?

@czahl I dont know which files kirk used to create that repo. I use the firmware directly from the repo linked on the mystat paper.

@danielfp248 Thanks for the hint this is the reason. In the version referenced in the paper, the firmware is extended to support the 4 current ranges.

I need to actually do the real calibration when I find the time. I'l report back then.

@danielfp248 I managed to get the mystat working correctly and calibrate it too. The problem was the firmware. I was using the one from @kirk's repo but that's the one working for only 3 current ranges. https://github.com/matthew-yates/MYSTAT/blob/main/firmware/firmware.hex is the correct one to use with the updated board. Should I create a pull request?

@sepi yes, please do.
