Hello again @felmue,
I came across this Adafruit video today, and I thought maybe you'd be interested?
(The interesting part is between 6'52" and 13'05")
Being a beginner in electronics, I am wondering how to make current measurements with such low intensities (µA). Would you be so kind as to explain to me how you do it and with which model of measuring device. Pictures are welcome if it doesn't take too much time.
Thanking you in advance
If you don't need the I2C bus at all, you can disable it like this:
Try it to see if it solves your problem.
Are you sure the 18650C hat has its own charging circuit?
I thought we had to connect the M5StickC for the charge to be managed by its AXP192 controller?
Also, how do you know when the charge is complete? Is there an indicator LED for this?
