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
