time.h File Reference

Detailed Description

Universal timing functions for FastLED.

This header provides a universal fl::time() function that works consistently across all FastLED-supported platforms. It abstracts away platform-specific timing implementations and provides a clean, testable API.

Usage

#include "fl/time.h"
 
void loop() {
    fl::u32 now = fl::time();
    
    // Use timing for animations
    static fl::u32 last_update = 0;
    if (now - last_update >= 16) { // ~60 FPS
        update_animation();
        last_update = now;
    }
}

Support

For unit testing, time injection is available:

#ifdef FASTLED_TESTING
#include "fl/time.h"
 
TEST(AnimationTest, TimingTest) {
    fl::MockTimeProvider mock(1000);
    fl::inject_time_provider(mock);
    
    EXPECT_EQ(fl::time(), 1000);
    
    mock.advance(16);
    EXPECT_EQ(fl::time(), 1016);
    
    fl::clear_time_provider();
}
#endif
