I want to add CDC in an UVC project,but i'm not sure where to add the CDC descriptors.when put them into CyFxUSBDeviceDscr[]{...} and CyFxUSBHSConfigDscr[] {...}, the FX3 equipment can't emunerate right,and the virtual serial port and FX3 equipment can't

how to make sure the FX3 equipment and the virtual com port can exist in the same time?

Hello,

Please refer to this thread Add CDC device to UVC . The attached firmware is for CX3. You need to make similar changes to the FX3 firmware and follow the steps after programming the firmware to fx3

The changes for adding CDC device are done:

- Adding the descriptors in .dscr file

- Created a thread for CDC application

- Handling of CDC class requests

- Creating DMA channel for transfers UART to USB

Please let me know if you have some problem

Regards,

Rashi
