    Problem Tuning CapSense Using UART


      I have a CY8CKIT-049-4200 prototyping kit and I want to tune the CapSense buttons over UART through its onboard CY7C65211 USB-UART bridge.



      I followed the datasheet PSoC 4 Capacitive Sensing 5.0, page 120.

      I set up the UART SCB component at TX-only, 115200 bps, 8 bits accordingly.

      Then I copied the example code to the main.c, flash the program under bootloader.

      After I launch the Sense Tuner I set the communication the same as the UART SCB.


      Then after I clicked "connect", I got the error "The requested packet is not found" after several seconds.



      In addition, If I try to replug the USB cable, there's a possibility that the cursor of my computer will go mad, it will move randomly and this symptom disappears when I pulled the Tx wire on the PSoC. I tried switching the USB port, reinstall IDE with driver and working on another PC but with no luck.



      Windows 10 Pro x64 build 16299,

      PSoC Creator 4.2



      Any help is appreciated.
