Hossein,

We don't seem to have any reference code for the FDC2112, but we do have firmware that can be downloaded for a reference design based on the FDC2214, which is a very similar part.

You can download the firmware from theTIDA-00466: Noise-immune Capacitive Proximity Sensor System Reference Design page.

Just so you know, we recommend the FDC1004 over devices from the FDC2xxx family.
Customers have struggled to get to production with the FDC2xxx devices because of EMI.

The FDC1004 has active shield drivers that can help manage EMI.

If you would like to know more about the device, please take a look at the E2E FDC1004 FAQ page.

Regards,
John

Hi John

Thanks a lot for your support, is really valuable, as always with the TI tickets.

I have a problem

I set up fdc2112 but I don't know what value to set the OFFSET_CHx value.

Here I set the OFFSET value to 0x0000 and my DATA_CHx only changes between 11 and 12.

Many thanks,

Hossein Mirjalili

Hossein,

I am not sure I understand what you are asking, and why the result is not good.

Could you please provide some additional detail?

Regards,
John
