    First release of Trireme FM-1: custom firmware that turns the M-VAVE FM-1 into a programmable USB keyboard and macro pad.

    Vibe-coded firmware. It runs on my own FM-1, but not every function has been tested by hand. Keep the stock firmware at hand.

    What's in it

    • Any key, shortcut, media or mouse key on every note key, button and KNOB1-4
    • Five layers: hold, one-shot, go to, toggle, layer-tap, mod-tap, one-shot modifiers
    • Macros, tap dance, combos and the QMK timing settings (edited in Vial)
    • Vial support: the layout is built in, no definition file needed
    • An on-device editor (OCT+), with a live legend on the screen
    • Per-key light styles per layer
    • The configuration is kept in flash and survives reinstalling the stock firmware

    Installing

    1. Install the stock V15 firmware first.
    2. Install trireme-fm1-v0.1.fwsc like any FM-1 firmware package (see the README).

    To go back: install stock V15. OCT- + OCT+ held 10 s, or OCT+ held at power-on, puts the FM-1 in update mode.
