Dinghy
Minimal base firmware to build your own on: update path, USB rescue, USB MIDI and audio, panel, screen and settings working and documented, with a sine wave on top.

Brick risk. Flashing this carries a known, documented risk of damaging the device.

Description
Classified as firmware rather than a tool because it is a flashable image (a 4-voice sine synth) that people copy and extend; it is tagged platform and sdk to mark its role as a starting skeleton. The README has a step-by-step build-your-own guide.
Install notes
Installs from the FM-1 Firmware Hub listed on fm1-editor.com, or build and flash with the Makefile.
