Hi Christian,
The voltage range on the ADC is 0-1.8V and the Result is actually the voltage. The precision should be 15 bits, and I agree the Raw doesn’t correspond to this, could be a bug… will examine this.
For sysfs the reading is in uV while the AT command reports in mV.
So, at 6v, you’re reading is full scale at 1.797v
BR,
Chris
