This is very simple test of USB HID device on STM32F103 blue pill board . This device should be able to do following stuff:
- volume up/down/mute
- play/pause
- previous/next song
- lock computer
TODO:
- Design PCB Most of the code comes from Oliv' (http://notes.iopush.net/stm32-custom-usb-hid-step-by-step-2/)
