rgbww.cpp.hpp File Reference

Detailed Description

Dispatch + implementations for the 5-channel RGB->RGBWW path (issue #2558, Phase 3 of #2545).

The colorimetric modes call solve_rgbcct() from fl/gfx/rgbw_colorimetric.h whenever FASTLED_RGBW_COLORIMETRIC is defined (that's the one flag that gates the underlying color math library — see PR #2552). Without it, the dispatch emits FL_WARN_ONCE and outputs five zero bytes. Suppress the warn-once with -DFASTLED_SUPPRESS_RGBWW_FALLBACK_WARNING=1.

There is intentionally no separate FASTLED_RGBWW gate: –gc-sections already drops every RGBWW symbol for sketches that never configure a channel with mWhiteCfg = Rgbww{...}, so a second compile flag would only add an extra define for users to remember without any flash savings.
