# 7-bit command sweep notes

## Revised protocol (after sweep)

Layout: `PPP M BGR` (7 bits, MSB first). Same pulse timing as before.

| Field | Bits | Meaning |
| ------- | ------ | --------- |
| PPP | 3 | Pattern (8 modes — not 4) |
| M | 1 | Palette / multi flag |
| BGR | 3 | Color or palette select |

The old write-up treated this as `0 PP M BGR` (leading bit always 0 + 2 pattern bits). The leading bit is actually **pattern bit 2**; the app simply never used patterns `100`–`111`.

### Patterns (`PPP`)

| PPP | Name (working) | Behavior |
| ----- | ---------------- | ---------- |
| `000` | Steady | Solid color / palette |
| `001` | Fade | Fade (OEM “Fade”) |
| `010` | Sparkle | Sparkle to white (OEM) |
| `011` | Firefly | Firefly (OEM) |
| `100` | Twinkle | Mostly off; random bulbs flash on in color (colored sparkles on dark) |
| `101` | Fast sparkle | Like Sparkle but faster |
| `110` | Anti-sparkle | Base color on; sparkles turn bulbs **off** (black sparkles) |
| `111` | Fast twinkle | Faster version of Twinkle (`100`) |

### Color / palette (`M` + `BGR`)

When `M=0`, `BGR` is a normal solid color (same as before):

| BGR | Color |
| ----- | ------- |
| `000` | Off |
| `001` | Red |
| `010` | Green |
| `011` | Yellow |
| `100` | Blue |
| `101` | Magenta |
| `110` | Cyan |
| `111` | White |

When `M=1`, `BGR` selects a **palette** (not a single RGB mix):

| BGR | Palette |
| ----- | --------- |
| `000` | Classic multi (per-bulb random across colors) |
| `001` | Christmas — red / white / green |
| `010` | July 4th — red / white / blue |
| `011` | Same as classic multi (indistinguishable from `000` in testing) |
| `100`–`111` | Often **off** or pattern-dependent (see tables; Fade/Firefly sometimes treat these as solid B/M/C/W) |

Palette behavior depends on pattern (e.g. Steady+Multi+`1xx` → off; Fade+Multi+`1xx` → solid colors; Sparkle+Multi+`1xx` → dark with white sparkles).

### OEM / app subset

The phone app only used `PPP` in `000`–`011` with either solid colors (`M=0`) or Multi (`M=1`, `BGR=000`). Hidden: palettes `001`/`010`/`011` and patterns `100`–`111`.

---

## Known (skipped by early sweep sketch)

- `PPP` `000`–`011`, `M=0`, any `BGR` → published Steady/Fade/Sparkle/Firefly × colors  
- `PPP` `000`–`011`, `M=1`, `BGR=000` → Multi with those patterns

## Summary

- **8 patterns**, not 4 — high bit selects the alternate set (twinkle / fast sparkle / anti-sparkle / fast twinkle).
- **`M=1` is palette mode**: `000`/`011` classic multi, `001` Christmas R/W/G, `010` July 4th R/W/B; `1xx` is pattern-dependent (often off).
- Fade/Firefly + Multi + `1xx` oddly map to solid B/M/C/W — possible alias or shared decode path.
- Names above (Twinkle, Fast sparkle, etc.) are working labels from observation, not OEM names.
