AFE4410: DC Offset calibration via firmware

Part Number: AFE4410

Hi Team,

I am working with someone using the AFE4410 and now trying to implement DC offset calibration on it.

We know there are some functions that seem to do that on the sample firmware for the eval board that was received so we tried porting those to hardware, but it does not seem to be working. Configuring and acquiring data from the AFE4410 is working fine.

Can you confirm that that part of the firmware should be working properly? The main reason that I ask is that the software for the AFE4410 EVM does not mention this feature, and that firmware needs to receive a command on the USB to start the calibration process.

Is there maybe an updated firmware package?

Are there some specific settings we need to change in that firmware for the calibration to work?

Regards,

RJ
