An open firmware for MIDIPLUS SmartPAD (being a pretty cheap launchpad-like MIDI-controller)

This project is developed and maintained by DerFetzer.

• The used STM32F103RBT6 unfortunately has flash read protection activated and there is a function that resets the microcontroller when there is activity on the SWD interface.

• There is an update mechanism in the original firmware but I did not look at it for long. Current updater can be downloaded at MIDIPLUS homepage.

• s0len0id assembled a great documentation of stock firmware function here.

• In order to remove read protection you have to mass erase the device, so the original firmware will be lost. You have to try during startup with something like the following:

$ openocd -f /usr/share/openocd/scripts/interface/stlink-v1.cfg -f /usr/share/openocd/scripts/target/stm32f1x.cfg  -c init -c "reset halt" -c "flash banks" -c "stm32f1x mass_erase 0" -c "stm32f1x unlock 0"

• For reverse engineered information about the used hardware see hardware folder.

• This firmware is designed to be used with the HID-bootloader.

• Have a look at the included Ardour MIDI map to get an idea of used MIDI messages.

• rust-std components (pre-compiled core crate) for the ARM Cortex-M3 targets. Run:

$ rustup target add thumbv7m-none-eabi
