ADC measure negative voltage??
Re: ADC measure negative voltage??
You don't really need to turn off the ADC? Unlike the timer it's not doing anything when you're not using it.

I think some hardware issues on my side, I have multiple IO, ADCs, connect to other device. The issue is when I power cycle other device once a while cause pyboard ADC not working anymore. But if I power down by steps, 3.3, 2.5, 2, 1.5..0 and the issue fixed.

I have more question...
Is it any free to use R/W register that I can save calibration value for each board, that won't get erase even Factory reset?
