wait_spin_budget.h File Reference

Detailed Description

Runtime-tunable microsecond spin budget for the channel-manager and driver wait loops (Phase 1 of #2815 / #2818).

The wait sites in fl/channels/manager.cpp.hpp and fl/channels/driver.cpp.hpp use a tiered structure: Tier 1 - instant non-blocking condition check Tier 2 - bounded microsecond spin (this budget) Tier 3 - cooperator yield, NetworkDetector-gated (added by #2817)

Tier 2 catches short DMA tails (APA102 small strips, WS2812B <=8 LEDs) without paying the FreeRTOS >=1 ms tick floor. Default 250 us. Set to 0 to disable the spin tier entirely.

Public-facing entry points live on CFastLED: FastLED.setWaitSpinBudgetUs(N) FastLED.getWaitSpinBudgetUs()
