Suzuki Protocol

Rust module: src/protocols/suzuki.rs
Reference: REFERENCES/ProtoPirate/protocols/suzuki.c

Overview

Suzuki uses PWM: 250 µs HIGH = 0, 500 µs HIGH = 1; LOW 250 µs after each bit. 64 bits total. Preamble: 350 short HIGH / short LOW pairs; 2000 µs gap at end. Field layout: serial = (data_high&0xFFF)«16

data_low»16; btn = (data_low»12)&0xF; cnt = (data_high«4)»16.

Timing

Parameter	Value	Notes
Short (0)	250 µs	±99 µs
Long (1)	500 µs	±99 µs
Preamble	350 pairs
Gap	2000 µs	±399 µs
Min bits	64

Encoding

PWM: 250 µs HIGH = 0, 500 µs HIGH = 1; LOW 250 µs after each bit.

Frame Layout (64 bits)

• serial: (data_high & 0xFFF) « 16

  data_low » 16

• button: (data_low » 12) & 0xF
• counter: (data_high « 4) » 16

Decoder Steps

1. Reset — Wait for short pulse (preamble).
2. CountPreamble — Count 350 short pairs; on 2000 µs gap → DecodeData.
3. DecodeData — Short = 0, long = 1; at 64 bits parse fields and return.

Encoder

Supported; 350 preamble pairs, gap, 64 PWM bits.

Frequencies
