Good morning

I need to use the offset feature of the ADC. After the chip calibration I need the system calibration.

I read the result of conversion with my zero reference as a value: 2090, and it should be 2047 as midscale.

The offset register shows the value 0xFFFF. I don t find a good strategy for writing the right compensation value

there to produce what I want. I verify that writing 340 I have what I need but what is the logic?

I am using the 12 bits resolution

Thank You...
