Sure, where are they? I looked through all your documentation and can’t find them mentioned.
As an update, I strangely got the manual firmware to work.
I did it by NOT pressing S1 and S2 on power up. I got the read_sensors.py example to work by pip3 installing the power api software, then running read_sensors… oddly I have to reinstall the power-api software via pip everytime I reboot…
However, after successfully getting read_sensors to work, I then tried update_firmware.py and it too worked. It went all the way through the percentages and reported that version 0.3.0 was successful.
Either something weird is going on with my board, or your documentation is waaay off.
