Method References

groupBulkWrite

• Syntax

  int groupBulkWrite(int port_num, int protocol_version)
  

• Parameters

Parameters	Description
port_num	Port number
protocol_version	Protocol version

• Detailed Description

  This function initializes the parameters for packet construction. The function resizes groupData struct and initialzes struct members.

groupBulkWriteAddParam

• Syntax

  bool groupBulkWriteAddParam(int group_num, byte id, UInt16 start_address, UInt16 data_length, UInt32 data, UInt16 input_length)
  

• Parameters

Parameters	Description
group_num	Group number
id	DYNAMIXEL ID
start_address	Start address
data_length	Data length
data	Data for write
input_length	Input data length

• Detailed Description

  This function pushes id into the DYNAMIXEL ID list, and initializes #group_num parameter storage by setting start_address and param_length. The function deals with 1, 2 or 4 byte data only. The function returns false when the length of input data exceeds parameter or wrong length, or returns true.

groupBulkWriteRemoveParam

• Syntax

  void groupBulkWriteRemoveParam(int group_num, byte id)
  

• Parameters

Parameters	Description
group_num	Group number
id	DYNAMIXEL ID

• Detailed Description

  This function removes id and its data for write in the #group_num DYNAMIXEL ID list. The function returns false when no data is in the parameter storage, or returns true.

groupBulkWriteChangeParam

• Syntax

   bool groupBulkWriteChangeParam(int group_num, byte id, UInt16 start_address, UInt16 data_length, UInt32 data, UInt16 input_length, UInt16 data_pos)
  

• Parameters

Parameters	Description
group_num	Group number
id	DYNAMIXEL ID
start_address	Start address
data_length	Data length
data	data for write
input_length	Input data length
data_pos	Data position in the array

• Detailed Description

  This function pushes new data_length bytes data into #group_num parameter storage of same id. The function returns false when the target ID doesn’t exists in the ID list, or returns true.

groupBulkWriteClearParam

• Syntax

  void groupBulkWriteClearParam(int group_num)
  

• Parameters

Parameters	Description
group_num	Group number

• Detailed Description

  This function clears #group_num DYNAMIXEL ID list.

groupBulkWriteTxPacket

• Syntax

  int groupBulkWriteTxPacket(int group_num)
  

• Parameters

Parameters	Description
group_num	Group number

• Detailed Description

  This function transmits the packet by using BulkWriteTxOnly function. The communication result and the hardware error are available when the function is terminated.
