- Rename all show .txt files with NNN_ numeric prefix so order is explicit and controlled by filename (001_heartbeat_red through 006_party) - Drop HOME_SHOW special-casing from convert_all.py; show 0 is simply the lowest-numbered file - Add SHOW_FLAG_SPARKLE support: shows can declare '// flags: sparkle' to overlay random white flashes on top of the base color each frame - Wire sparkle into led_controller and config.h (SPARKLE_CHANCE/FRAMES) - Replace old placeholder/example shows with the six production shows Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* Plays lightshows defined in shows.h on a WS2812B LED strip.
|
||
* A single button navigates between shows:
|
||
* 1 tap — next show
|
||
* 2 taps — previous show
|
||
* 3 taps — lights off (any tap or hold resumes)
|
||
* hold — reset to show 0 (red heartbeat)
|
||
*
|
||
* To add or update shows:
|
||
* 1. Add or edit a .txt file in converter/shows/
|
||
* 2. Run: make shows
|
||
* 3. Run: make upload
