NRF52 + Csense Low Level Driver in Production

[Jared]

Hey All,

I'm curious, has anyone integrated the csense library or lower level driver into a device they've shipped? I'm quite worried about variation and also difference in temperature affecting the readings leading to false positives and negatives. Of course, it would be great to integrate. We would save some cost and board space that would otherwise be used for a cap-sense specific IC.

Thanks

Hi,

Did you see the Capacitive Touch on the nRF52 series tutorial? Maybe someone in the community will comment if they have integrated a solution in their production.

Best regards,
Jørgen

Hi Jørgen

I did see the tutorial and got something up and running. I wasn't getting great SNR from the ADC technique. I ended up going with an off the shelf IC. Too many things to test end not enough time!
