Hi

I have question please answer

How you remove adc offset of xmega? I worked hard to build my own DAQ but the offset always vary when micro power up. I use Diff mode and connect neg input to ground.

I perform offset compensation. I read the offset from the ADC when there is no signal during calibration, then I subtract this during normal operation.
