#include <pr/hdlc/decoder.hpp>

Streaming HDLC decoder.

Input contract:

Output contract:

This stage intentionally stops before FCS validation.

Public functions

auto pop_byte(std::uint8_t* out_byte) -> bool: Pop one decoded byte.
auto pop_event(FrameEvent* out_event) -> bool: Pop one frame event.
auto pop_frame(DecodedFrame* out_frame) -> bool: Pop one completed HDLC frame.
void process_level_bit(bool level_bit): Feed one raw channel level bit (NRZI level).
void reset(): Reset all decode state and clear output queues.

Pop one decoded byte.

Returns	`true` if a byte was available.

Pop one frame event.

Returns	`true` if an event was available.

Pop one completed HDLC frame.

Returns	`true` if a frame was available.

The returned frame contains bytes exactly as transmitted between HDLC flags (after NRZI decode and bit destuffing), including trailing FCS.
