This project is currently only made for the purpose of learning ARM based processors, building toolchains, cross compiling and learning the building/linking processes
All of the following configurations and tools are designed to be runned in Linux based operating systems.
- Fully open source as the name implies :)
- 3D Printed expression pedal which communicates using the MIDI protocol.
- AS5600 Magnetic Encoder is used for reading the angle of the pedal. This is totally unnecessary and complicates lots of things, but has been chosen for the sake of learning.
- Uses any STM32L4xx based MCU. The code is written mostly using the
STM32L4xxHAL. Currently can be built only for theSTM32L432, but this is limited by startup scripts and some parts that use direct register access.
- All moving joints in the pedal use bearings for smooth action
- Always locked in the upright position by springs
- Simple rotating disk mechanism for achieving the springines with configurable tension

- Includes preconfigured launch options for debugging
launch.json, with GDB + STLink. - Easy debugging with prebuilt vscode tasks that automaticly build the project according to debug options.
- Semihosting is supported (Seperate launch option)
- Preconfigured build options.
- Semihosting can be enabled easily, which automaticly includes the necessary libraries and correct build linker flags.
