I *was* using a wrong "busy" pin! When I changed the pins in the firmware, I looked them up in an old version of the datasheet! 🤦 Now it refreshes like it should! Also, I can power it using a LiPo! \o/
Next problem: The battery level indicator chip isn't reacting – when I speak to it using I2C, I get no response. I'll try to double-check the data sheet, to see if I wired it up correctly?
