Hi all,

I have a brief question concerning the design of mutual capacitance sensors as described in this section, p.116:

http://www.cypress.com/file/46081/download

As shown in Figure 6-8, the button consists of two RX electrodes connected to one another. However, it does not mention (if I have not missed anything), how the TX electrodes are connected. Is it done by routing the traces to the PSoC and connecting these at the pin or is it done by vias underneath the other RX electrodes?

 

Thanks.

Regards

Hi,

 

It is done by routing traces underneath the RX electrode through via.

 

Thanks,

Yuva.
