The Daisy Pod hardware arrived (Seed 1.2 / PCM3060). Build the controls
phase on top of the audio spike: encoder turn = tempo, push = play/pause,
buttons step the program list, knob 1 = volume, RGB LED 1 = beat colored
by dynamic, RGB LED 2 = transport. Boot still plays the spike groove so
the spike's decision criteria stay observable.
- pm-synth: add Player::{position,seek,set_volume,last_level} + Synth::
set_master, with host tests (tests/player.rs). Live tempo/program
changes rebuild the Player in thread context and swap it in under a
short critical section, preserving loop phase (seek) on tempo changes.
- pm-daisy: SysTick 1 kHz millis tick, non-blocking beat flash, and
PLAYING/VOLUME/LAST_LEVEL atomics the audio IRQ honors/publishes.
- New modules controls.rs (buttons/encoder/pots, libDaisy debounce +
quadrature decode, 1 kHz poll), leds.rs (active-low RGB + boot
self-test), programs.rs (spike groove at index 0 + pm-grid grooves).
- Pin map verified against libDaisy daisy_pod.cpp + the daisy crate's
pins.rs. Builds clean for all three Seed revisions; 91 KB/128 KB flash.

//! The built-in program list the two Pod buttons step through. Index 0 is the spike pattern, so
|
|
//! boot behavior is identical to the original spike (`docs/daisy-spike.md`); the rest are lifted
|
|
//! from the Grid firmware's `STYLES` / `PRACTICE` sets (`rust/pm-grid/src/main.rs`) so the editions
|
|
//! share one groove vocabulary. All are plain track-format strings — `track_format::parse` handles
|
|
//! them and `pm_synth::Player` schedules them at a fixed tempo (any `rmp`/`tr` directives parse but
|
|
//! don't animate here; the polyrhythm and odd-meter grooves are the interesting ones for the Pod).
