Hi cxandy. Thank you so much for your contribution. I am really unsure how to proceed here but while I think it would be great to have support for more hardware I also think all the #ifdefs make the code much harder to understand. One very important goal is that the code is a starting point for beginners and the compiler switches make this a lot harder to understand. So I suggest that I will set a link to your AZMZ repository but will remove the compiler switches (and with this hardware support for the AZSMZ HW. I hope you understand... Would you like me to set the link?

Hi cxandy & squix78.
Could you please merge the nice battery percent bar implementation, say conditionally by #define BAT of course, and add some info about voltage divider resistor values as well as the battery type designed for?
I believe it is pretty generic to allow other people to play even without specific battery charging management board.
Best Regards!
