ARM Cortex-M4F Synthesizer
I made a fully functioning MIDI synthesizer using an ARM Cortex-M4F development board, C++ and various circuitry for MIDI input and audio output. The code is written in C++ and is available on GitHub here.
Schematics for the circuitry can be found in the "documentation" directory of the GitHub project here. Any questions, just let me know, I'll be happy to discuss this project farther. Contact info here.
