STM32F1 MIDI Serial Bridge

This code is a firmware for the STM32F1 that provides a MIDI-USB -> MIDI-Serial Converter and a MIDI-Serial -> MIDI-USB Converter. It can be used with the Arduino MIDI library.

Status

working!

Usage

The pins for the serial communication are A9 (Serial TX) and A10 (Serial RX). [USART1]

connect those pins to your MIDI device, but if you connect it to a genuine midi device you must change the baudrate to 31250 (current 115200)

Build

Clone : git clone https://github.com/DarkSunHD/STM32F1_MIDI_Serial_Bridge.git

Go into the folder: cd STM32F1_MIDI_Serial_Bridge

Clone submodules: git submodule update --init --recursive

Go into the "libopencm3" folder: cd libopencm3/

Build "libopencm3": make

If make isn't installed, you can install it with the following command (Ubuntu)
sudo apt install make

If make doesn't work you may are missing the arm toolchain to install the arm toolchain use this command (Ubuntu)
sudo apt install gcc-arm-none-eabi

Go in the "src" folder: cd ../src/

Now you can use the Makefiles to build the firmware.

Current Makefile

ST-util must be installed.

Usage:

plug in the STM32 and run make the script will compile the code and flash the binary file to the stm32

For the Makefile.old

Build

remove the Makefile and rename the Makefile.old to Makefile

or Build the bin firmware make bin -> *.bin

Flash

Flash with st-utils

Open a terminal (terminal1) and go to your *.elf file then type: arm-none-eabi-gdb file.elf

Now open a new terminal (terminal2) and run the st-utils st-util

go back to terminal1 and type: tar extended-remote :4242 (4242 is the port st-util opens)

now write the file to the stm32 (terminal1) load
