Some of the voltage outputs are programmable via registers, so it appears to be possible to damage your CHIP computer by writing the wrong data to certain registers on this chip. | Some of the voltage outputs are programmable via registers, so it appears to be possible to damage your CHIP computer by writing the wrong data to certain registers on this chip. | ||
This script only uses one write command to enable ADC registers, everything else is only reading | This script only uses one write command to enable ADC registers, everything else is only reading | ||
