Since your last updates there is something changed with the axp2101, because the battery is not working.
Only powering over usb is working!

I found this docu.

maybe it helps.

HI,
in the file I posted at the beginning (this one) you can find all the info required.

You can use the same approach you did for powering the TFT

Enjoy

if i press the power on button witch is pin30 of the axp the modul stays black.
only if i plug in the usb-cable the modul starts up.

As you may have noticed, implementing new functionalities in the code without having the hardware is lengthy and tedious. Out of curiosity, I still wanted to do it, and ultimately, it worked, but it took several days whereas it would have taken only a few hours to sort everything out. However, concerning the battery charger, I prefer not to attempt it because it could damage the module and the battery if excessive charging current is sent.

So, I'm happy to see that you found the right tuning parameters for the battery.

Hopefully, this will be helpful to more people.
