USB-MIDI

Refer to sample code of STM32_USB-Host-Device_Lib_V2.1.0. (STM website for details).

Created USB-MIDI example from USB HID Sample.

1. MOdified functions on STM32F2XXX platform.

   STM32_USB-Host-Device_Lib_V2.1.0/Project/USB_Device_Examples/MIDI/src/stm32fxxx_it.c STM32_USB-Host-Device_Lib_V2.1.0/Project/USB_Device_Examples/MIDI/src/usbd_desc.c STM32_USB-Host-Device_Lib_V2.1.0/Project/USB_Device_Examples/MIDI/src/usbd_usr.c STM32_USB-Host-Device_Lib_V2.1.0/Project/USB_Device_Examples/MIDI/inc/usbd_conf.h STM32_USB-Host-Device_Lib_V2.1.0/Project/USB_Device_Examples/MIDI/inc/usb_conf.h

2. Create USB MIDI Class Libraries STM32_USB-Host-Device_Lib_V2.1.0/Libraries/STM32_USB_Device_Library/Class/midi/src/usbd_midi_core.c STM32_USB-Host-Device_Lib_V2.1.0/Libraries/STM32_USB_Device_Library/Class/midi/inc/usbd_midi_core.h

3. Create one Test App STM32_USB-Host-Device_Lib_V2.1.0/Project/USB_Device_Examples/MIDI/src/app.c

4. Verified USB with Test Suite USB30CV

   STM32_USB-Host-Device_Lib_V2.1.0/Libraries/STM32_USB_Device_Library/Core/src/usbd_req.c Note: Modified Core Libraries in order to get pass from Diagnostic Test Suite of USB30CV
