Method References

groupBulkRead

• Syntax

  int groupBulkRead(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.

groupBulkReadAddParam

• Syntax

  bool groupBulkReadAddParam(int group_num, byte id, short start_address, short data_length)
  

• Parameters

Parameters	Description
group_num	Group number
id	DYNAMIXEL ID
start_address	Start address
data_length	Data length

• Detailed Description

  This function pushes id to the DYNAMIXEL ID list, and initializes the parameter storage by setting start_address and data_length.

groupBulkReadRemoveParam

• Syntax

  void groupBulkReadRemoveParam(int group_num, byte id)
  

• Parameters

Parameters	Description
group_num	Group number
id	DYNAMIXEL ID

• Detailed Description

  This function removes target id in the #group_num DYNAMIXEL ID list. It returns false when the class uses Protocol 1.0 .

groupBulkReadClearParam

• Syntax

  void groupBulkReadClearParam(int group_num)
  

• Parameters

Parameters	Description
group_num	Group number

• Detailed Description

  This function clears the #group_num DYNAMIXEL ID list. It returns false when the class uses Protocol 1.0, or returns true.

groupBulkReadTxPacket

• Syntax

  void groupBulkReadTxPacket(int group_num)
  

• Parameters

Parameters	Description
group_num	Group number

• Detailed Description

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

groupBulkReadRxPacket

• Syntax

  void groupBulkReadRxPacket(int group_num)
  

• Parameters

Parameters	Description
group_num	Group number

• Detailed Description

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

groupBulkReadTxRxPacket

• Syntax

  void groupBulkReadTxRxPacket(int group_num)
  

• Parameters

Parameters	Description
group_num	Group number

• Detailed Description

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

groupBulkReadIsAvailable

• Syntax

  Boolean groupBulkReadIsAvailable(int group_num, byte id, short address, short data_length)
  

• Parameters

Parameters	Description
id	DYNAMIXEL ID
address	Address on the control table of DYNAMIXEL
data	Packet data

• Detailed Description

  This function checks whether there is available data in the data storage. It returns false when there is no data from target address, or returns true.

groupBulkReadGetData

• Syntax

  int groupBulkReadGetData(int group_num, byte id, short address, short data_length)
  

• Parameters

Parameters	Description
group_num	Group number
id	DYNAMIXEL ID
address	Address on the control table of DYNAMIXEL
data_length	Data length

• Detailed Description

  This function gets specific data from received packet. It returns false when there is no data from target address, or returns true.
