WRITE_SERIAL_BURST

This structure defines a burst output configuration for writing multiple GPIO ports simultaneously. It is mainly used when sending bulk digital output commands to the robot’s control box or arm modules. Each burst operation specifies a location, port count, and port data array.

BYTE#	Field Name	Data Type	Value	Remarks
0	_iLocation	unsigned char	0 or 1	Target hardware location 0: Control Box 1: Arm-mounted I/O
2	_iCount	unsigned short	0~16	Number of GPIO ports included in this burst operation
4	_tPort[MAX_DIGITAL_BURST_SIZE]	GPIO_PORT		Array containing the configuration of each output port

Total size: 132 bytes
