<![CDATA[M5 with ADC does a reset]]>Hello everybody
I measure the voltage of a 3.2V LiFePo4 cell of a solar battery on a Fire with the ADC unit via a voltage divider (2x15kOhm).
When the sun comes out, the M5 sometimes resets...
What can be the reason?
Greetings Felix

you would be better of using a VMeter unit instead of the adc to measure voltage as under high sun it could be overloading the 3,3v max input pin causing the reset.
