A simple USB MIDI implementation on STM32F103 uC with CubeIDE

This is a tutorial to demonstrate a very simplified USB MIDI implementation on STM32F103 microcontroller using CubeIDE and its inbuilt-libraries. Here the stm32f103c8t6 based board, also known as blue-pill is programmed such that it sends MIDI-Note-On and MIDI-Note-off messages to the host alternatively every 0.5 seconds. The code here can be upgraded to a full fledged MIDI keyboard, by adding switches/ buttons to the microcontroller to send the appropriate notes w.r.t each button press.

Since I am not an expert in USB protocols and STM32 microcontrollers, I will have to leave that part to professionals and experts.
