I-CUBE-USBD-Composite

A wrapper class around ST USB stack to create STM32 USB Composite devices with ease.

Modifications

• CDC supports multiple instance
• Removed ST use of malloc
• UAC Microphone & Speaker separated
• HID Keyboard & Mouse separated

TODO

• Add CubeMX Templates
• Fix UAC combination with other classes

How to use

1. Download AL94.I-CUBE-USBD-COMPOSITE.1.0.0.pack from repo.

2. Add AL94.I-CUBE-USBD-COMPOSITE.1.0.0.pack to CubeMX.

3. Inlude in project

Enable USB peripheral & NVIC

Add middleware to project

Add components to project, Selection of Core & COMPOSITE is must

Enable the classes you want

Dont forget!!!

4. Generate Code

Call MX_USB_DEVICE_Init(); manually

Enumerated

1. USB CDC ACM.

2. CDC & HID.

3. RNDIS.

4. UAC Microphone & Speaker.

5. UVC Camera & Mass Storage.

Troubleshooting

1. Cross check number of endpoints in MCU & consumed by application.
2. Adjust Endpont Size & PMA buffers in "Target/usbd_conf.c" accordingly.
3. For some classes "SOF" must be enabled!!!
4. Make sure MCU clock is configured properly & USB Interrupt is enabled.
5. For L5 HAL_PWREx_EnableVddUSB() needs to be called before enabling USB operation.
