* allstar_firefly.h - Allstar Firefly 318ALD31K native SubGHz protocol
|
|
*
|
|
* Registers the Allstar Firefly gate remote as a first-class SubGHz protocol,
|
|
* supporting decode from air, save/load of .sub files, and retransmit.
|
|
*
|
|
* Protocol summary (measured from captured remotes):
|
|
* Carrier : 318 MHz OOK (FuriHalSubGhzPresetOok650Async)
|
|
* Code type : Static 9-bit trinary (Supertex ED-9 encoder IC)
|
|
* Frame : 18 symbols (2 per bit), no separate sync pulse
|
|
* Repeats : 20 frames per keypress
|
|
* Inter-frame gap: ~30 440 us
|
|
*
|
|
* Symbol encoding - each bit = two (pulse, gap) pairs:
|
|
* '+' ON : H H = [4045us HIGH, 607us LOW] x2
|
|
* '-' OFF : L L = [530us HIGH, 4139us LOW] x2
|
|
* '0' FLOAT : H L = [4045us HIGH, 607us LOW, 530us HIGH, 4139us LOW]
|
|
*
|
|
* Save file format:
|
|
* Filetype: Flipper SubGhz Key File
|
|
* Version: 1
|
|
* Frequency: 318000000
|
|
* Preset: FuriHalSubGhzPresetOok650Async
|
|
* Protocol: Allstar Firefly
|
|
* Key: +--000++-
|
|
*
|
|
* To register with the SubGHz app, in protocol_list.c add:
|
|
* #include "allstar_firefly.h"
|
|
* &subghz_protocol_allstar_firefly, (in the protocol array)
