Manually adjust the sensitivity of psoc4 touch key

[XiaoPing_Yang]

dear sir

          There are many items for the customer psoc4 to debug the sensitivity of touch keys. Using manual debugging options, the process is very troublesome. Is there a debugging method similar to 21234, only adjusting the peripheral resistance, so that the customer can debug himself.Or is there a simpler way to reduce work steps.

          Thanks.

Hi yaxi_1543386​,

If you using SmartSense, you can adjust the sensitivity by changing the finger capacitance value. Refer Figure 5.3 in CapSense design guide.

It is recommended to use CapSense Tuner GUI (synchronized mode) to fine tune the CapSense parameters.

We have provided detailed step by step instructions on how to tune a CapSense button for optimum performance in the CapSense design guide. Please refer to that and let us know if you face any issues in any step.
