M3508I: reconstructing the motor RS485 protocol

m3508i reconstructs the M3508I motor’s half-duplex RS485 command and reply format. The repository documents field offsets, motor selection, speed encoding and CRC16, and supplies a C frame builder and parser, an STM32 example and an adapter-board design.
