begin()

virtual bool fl::RxDevice::begin ( const RxConfig & config )

pure virtual

Initialize (or re-arm) RX channel with configuration.

Parameters

config

RX configuration (signal ranges, edge detection, skip count)

Returns

true on success, false on failure

First call: Initializes hardware and arms receiver Subsequent calls: Re-arms receiver for new capture (clears state)

Edge Detection:

• start_low=true: Skip symbols until first rising edge (LOW→HIGH), default for WS2812B
• start_low=false: Skip symbols until first falling edge (HIGH→LOW), for inverted signals

This solves the "spurious LOW capture" problem where RX captures the idle pin state before TX starts transmitting.

Example:

RxConfig config;
config.signal_range_min_ns = 100;   // Glitch filter
config.signal_range_max_ns = 100000; // Idle timeout
config.start_low = true;             // WS2812B idle = LOW
rx->begin(config);
