-## USB CDC Console (optional)
-
-This project includes an optional software USB CDC-ACM device stack using embassy-usb. It runs on the CH32V203’s USB device peripheral but implements the protocol fully in software (no built-in USB class firmware is required).

-How to enable:
-- Build with the `usb-cdc` feature: `cargo build --release --features usb-cdc`
 - Wire the MCU’s USB pins to a USB connector:
   - D+ (PA12)
   - D− (PA11)

 - Windows: Use PuTTY on the shown COM port.
 
-Notes:
-- The firmware currently implements an echo console: bytes you type are echoed back. You can extend it to print logs or interact with your application.
-- If you don’t see a device, ensure D+ (PA12) and D− (PA11) are connected and the cable supports data.
