    PSoC4 Mutual Capacitance Sensor Design

      Hi all,

         

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

      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.
