feat(attackshark): implement 0x25a7 GearHub protocol for X8 SE - #30
Merged
Conversation
Reverse-engineered from the qmk.top GearHub web driver bundle. Adds HID feature report communication (report ID 0x00, 64 bytes) with GearHub checksum, DPI get/set, polling rate set, and firmware version. Key additions: - checksum25a7() and encodeReport25a7() helpers - POLLING_CODES_25A7 map (125/250/500/1k/2k/4k/8k Hz) - getFirmware25a7(), getDpi25a7(), write25a7PollingRate() - read25a7Status() for full device initialization - 4 new unit tests for checksum and polling code mapping Protocol: 9-byte padded commands with one's-complement checksum at byte 7, sent as 64-byte HID feature reports on report ID 0x00.
