wait() [1/2]

void CFastLED::wait

(

)

Wait for all channel bus transmissions to complete.

Note

Normal animation code does not need to call this after show(); the next frame waits before reusing driver-owned data.

This overload waits indefinitely while cooperatively running system work. Use wait(timeout_ms) when the caller needs a bounded wait.

Safe to call on all platforms (no-op on platforms without channel bus).

Definition at line 795 of file FastLED.cpp.hpp.

                                 {
    // A zero timeout means wait indefinitely. The void API cannot report a
    // timeout, so returning early would violate its completion contract.
    // Dispatch only to consumers already in use; do not construct a manager
    // in legacy-only sketches just to wait for their direct driver.
    fl::detail::waitForDriverCompletion(0);
