Jimmy d5cab2efdf Add multi-panel Pico UDP firmware and Python LED control.

Pico panels get static IPs on 10.1.1.10–14 with per-panel LED counts, Makefile deploy targets, and Python examples for animations, sync tests, and direct Pi SPI control.

WS2812 LED control for Raspberry Pi 5 and Pico panel adapters.

Panel IPs

Five panels on 10.1.1.10–10.1.1.14 (panel 0 → .10, panel 4 → .14). Examples drive all 5 by default.

Panel sizes

Panels are 9 rows tall; width varies by panel. Edit PANEL_WIDTH_BY_INDEX in leds/array_config.py:

Panel	IP	Size	LEDs	Flash
0	10.1.1.10	9×39	351	`make deploy PANEL_ID=0 NUM_LEDS=351`
1	10.1.1.11	9×45	405	`make deploy PANEL_ID=1 NUM_LEDS=405`
2	10.1.1.12	9×45	405	`make deploy PANEL_ID=2 NUM_LEDS=405`
3	10.1.1.13	9×45	405	`make deploy PANEL_ID=3 NUM_LEDS=405`
4	10.1.1.14	9×39?	351	`make deploy PANEL_ID=4 NUM_LEDS=351`

Panel 4 may be 38 or 39 wide — find the exact width:

make deploy PANEL_ID=4 NUM_LEDS=387   # 43 cols max for probe
pipenv run python examples/panel_sync_test.py --test width --panel-index 4

Last column that lights → set PANEL_WIDTH_BY_INDEX[4] in leds/array_config.py to column + 1, then re-flash with NUM_LEDS=width×9 (342 for 38, 351 for 39).

Animations render at each panel's own width automatically.

Examples

Pico panel (UDP)

Command	What it does
`pipenv run python examples/panel_rgb_cycle.py`	Red / green / blue on all 5 panels
`pipenv run python examples/panel_color_test.py`	One-shot RGB + white test
`pipenv run python examples/panel_test.py`	Layout tests (corners, rows, chase)
`pipenv run python examples/panel_sync_test.py`	Positioning + sync across all panels
`pipenv run python examples/panel_animations.py`	All animations on all panels
`pipenv run python examples/panel_animations.py rolling`	One animation
`pipenv run python examples/panel_text.py`	Show your name
`pipenv run python examples/animations.py --panel`	Same as panel_animations

Single panel only:

pipenv run python examples/panel_animations.py --panel-index 1   # 9×45 @ 10.1.1.11

Pi direct (SPI on GPIO 10)

Command	What it does
`pipenv run python examples/animations.py`	All animations on matrix
`pipenv run python examples/matrix_demo.py`	Rainbow only
`pipenv run python examples/led_demo.py`	Dual-strip chase + rainbow
