Method References

addParam

• Syntax

bool addParam(UINT8_T id, UINT16_T start_address, UINT16_T data_length, UINT8_T *data)

• Parameters

id	DYNAMIXEL ID
start_address	Start address
data_length	Data length
data	Data for write

• Detailed Description

  This function pushes id to the DYNAMIXEL ID list, and initializes the parameter storage by setting start_address and data_length. It returns false when the target ID exists already in the ID list, or returns true.

removeParam

void removeParam(UINT8_T id)

• Parameters

Parameters	Description
id	DYNAMIXEL ID

• Detailed Description

changeParam

• Syntax

 bool changeParam(UINT8_T id, UINT16_T start_address, UINT16_T data_length, UINT8_T *data)

• Parameters

Parameters	Description
id	DYNAMIXEL ID
start_address	Start address
data_length	Data length
data	data for write

• Detailed Description

  This function pushes new data to the parameter storage of same ID. It returns false when the target ID doesn’t exists in the ID list, or returns true.
