Edgi_Talk_M33_USB_H CherryUSB Example Project

中文 | English

Overview

This project integrates CherryUSB on the M33 core of the Edgi-Talk board. It is configured for USB host mode and uses the Infineon DWC2 IP.

Default Configuration

  • RT_USING_CHERRYUSB = y

  • RT_CHERRYUSB_HOST = y

  • RT_CHERRYUSB_HOST_SPEED_HS = y

  • RT_CHERRYUSB_HOST_DWC2_INFINEON = y

  • Host class drivers: MSC, CDC, HID (configurable)

Build and Flash

  1. Build the project in RT-Thread Studio or with SCons.

  2. Flash the firmware via KitProg3 (DAP).

  3. Connect USB devices to the Type-C USB port for host operation.

Configuration (Switching Modes)

Open RT-Thread Studio and go to:

RT-Thread Settings -> USB -> CherryUSB

  • Host mode: enable RT_CHERRYUSB_HOST, select host IP under CHERRYUSB_HOST_IP (default: RT_CHERRYUSB_HOST_DWC2_INFINEON).

  • Host classes: enable required class drivers (MSC for USB storage, HID for keyboards/mice, CDC for serial devices, etc.).

  • Device mode: disable host mode, enable RT_CHERRYUSB_DEVICE, and select device template.

If an IP/class requires extra parameters, edit:

  • libraries/Common/board/ports/usb/usb_config.h
