Audio (the Scroll Pack has no speaker, so MIDI is the only path):
- usb-device 0.3 + usbd-midi 0.5 on the rp2040-hal UsbBus; enumerates as a
class-compliant MIDI device 'PM_G-1 Grid'.
- tick() emits a GM note-on per lane hit on channel 10 (note from the ported
SOUND_GM map, velocity by level) via send_bytes([0x09,0x99,note,vel]) — raw
4-byte packets, so arbitrary GM drum notes work without the named Note enum.
- USB polled every loop iteration AND during the boot splash (so the host can
enumerate during the ~2.5s animation).
Debug: defmt/defmt-rtt + panic-probe + flip-link; runner probe-rs run --chip
RP2040 (Pi Debug Probe). build.sh emits pm-grid.uf2 + pm-grid.elf; deploy serves
both; key info! log points + 1Hz heartbeat.
Web: drop CircuitPython from the PM_G-1 product. info-grid.html features the
Rust .uf2 download + accurate controls/views (X/Y swap, Ticker); build.sh +
deploy.sh no longer bundle/serve pm_g1_circuitpy.zip or pico-scroll-app.{py,mpy}.
pico-scroll/ stays as the reference port; editor FW_PATHS.G left for graceful
degradation.
