injectEdges()

virtual bool fl::RxDevice::injectEdges ( fl::span< const EdgeTime > edges )

pure virtual

Manually inject edge timings for testing (Phase 1 - PARLIO gap simulation)

Parameters

edges

Span of EdgeTime entries to inject (nanosecond timings)

Returns

true on success, false if not supported or failed

This method allows programmatic injection of timing data into RX devices for testing decoder behavior without actual hardware transmission. Primary use case is simulating PARLIO transmission gaps (~20us LOW pulses) to validate gap tolerance in LED decoders.

IMPORTANT: EdgeTime entries must use nanosecond timings, NOT ticks.

• RMT devices: Will store edges as-is in internal buffer (no tick conversion)
• GPIO ISR devices: Will store edges directly in timestamp buffer

After injection, use decode() to process the injected edges as if they were captured from hardware.

Example (simulate WS2812B with 20us gap):

auto rx = RxDevice::create<RxDeviceType::RMT>(1);
rx->begin(config);
 
// Generate EdgeTime sequence for 3 LEDs
fl::EdgeTime edges[144];  // 3 LEDs × 24 bits × 2 edges/bit
size_t count = generateLedEdges(leds, 3, edges);
 
// Insert 20us gap (extend last LOW pulse)
edges[count-1].ns += 20000;  // Add 20us to last LOW
 
// Inject edges into RX device
if (rx->injectEdges(edges, count)) {
    // Decode injected edges
    uint8_t buffer[9];  // 3 LEDs × 3 bytes
    auto result = rx->decode(timing, buffer);
}

Note

Not all RX devices support injection. DummyRxDevice returns false.
