Class Crc16

Namespace

MavNet.Protocol

Assembly

MavNet.Protocol.dll

CRC-16/MCRF4XX — the checksum MAVLink uses on every frame. The MAVLink community commonly calls this "CRC-16/X.25", but the reference C implementation omits the X.25 final XOR (xorout=0x0000), which is formally CRC-16/MCRF4XX (poly=0x1021, init=0xFFFF, refin/refout=true, check=0x6F91). Match the reference implementation byte-for-byte so PX4 accepts our outbound frames. Public because the code generator (tools/MavNet.CodeGen) reuses it for CRC_EXTRA computation.
