PSoC 6 MCU

Contributor

Hi,

I have a project in which I ground a fabric over a compressible overlay to detect any object. Following capsense design guidelines, should the fabric overlay be grounded to the VSSD with the star configuration as described in the guidelines pdf, or should it be grounded to supply ground plane? More precisely, on the image below, should it be connected to yellow or pink circle? (If any guidelines for this method is even possible, since it is a very uncommon design)

I plan on connecting the fabric through screws which would secure the connection through the P1 connector here on my pcb draft.pastedImage_1.png

P.S. This is meant to be used as a CSX touchpad widget.

Hi JeSi_4326976​,

You can connect the fabric to the supply ground (pink circle).
