i'm using the Infineon Cypress CY8C4147AZI-S475 mcu.

I am experiencing an issue with my CapSense configuration. I have set up CapSense to detect touch on a metal frame (iron), and everything works fine when the microcontroller is connected to the PC via USB, UART serial, or through the programmer board. However, when I disconnect the USB, touch detection no longer works.

Has anyone encountered a similar issue? Any suggestions on how to solve this would be greatly appreciated.

Thank you in advance!
