    Problem with CY8CMBR3116-LQXI

    RoIm_4475046

      Hi,

       

      I am having a problem with sensors from CY8CMBR3116-LQXI.

      This is on a 4 layer flex pcb.

      I have two chips configured on different I2C addresses.

      When I use EZ-Click to configure and test it, I get no response on several sensor channels.

      Attached are the system diagnostics of both of them.

      The sensor pads in the middle are non functional and the ones that show capacitance over 20cp are the ones working correctly.

      Could it be something on my pcb layout?

      I am attaching a screenshot of the pcb layout and gerber files.
