    Problem Tuning CapSense Using UART

    shaowd1998_3171886

      Purpose:

      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.

       

      Procedure:

      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.

       

      Environment:

      Windows 10 Pro x64 build 16299,

      PSoC Creator 4.2

       

       

      Any help is appreciated.
