# 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.

![INSTALLED](https://raw.githubusercontent.com/alambe94/I-CUBE-USBD-Composite/main/pics/USE/5.installed.png)

### 3. Inlude in project
Enable USB peripheral & NVIC
![NVIC](https://raw.githubusercontent.com/alambe94/I-CUBE-USBD-Composite/main/pics/USE/6.NVIC.png)

Add middleware to project
![INCLUDE](https://raw.githubusercontent.com/alambe94/I-CUBE-USBD-Composite/main/pics/USE/7.INCLUDE.png)

Add components to project, Selection of Core & COMPOSITE is must
![SELECT](https://raw.githubusercontent.com/alambe94/I-CUBE-USBD-Composite/main/pics/USE/8.SELECT.png)

Enable the classes you want
![ENABLE](https://raw.githubusercontent.com/alambe94/I-CUBE-USBD-Composite/main/pics/USE/9.ENABLE.png)

Dont forget!!!
![SELECT2](https://raw.githubusercontent.com/alambe94/I-CUBE-USBD-Composite/main/pics/USE/10.SELECT2.png)

### 4. Generate Code
Call MX_USB_DEVICE_Init(); manually

# 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.
