Member Function Documentation

bool GroupSyncRead::addParam ( uint8_t id )

The function that adds id, start_address, data_length to the Sync Read list.

Parameters

id	Dynamixel ID

Returns: false; when the ID exists already in the list; when the protocol1.0 has been used; or true

Definition at line 62 of file group_sync_read.cpp.

void GroupSyncRead::clearParam ( )

The function that clears the Sync Read list.

Definition at line 94 of file group_sync_read.cpp.

uint32_t GroupSyncRead::getData	(	uint8_t	id,
		uint16_t	address,

Parameters

id	Dynamixel ID
address	Address of the data for read Length of the data for read

Returns: data value

Definition at line 177 of file group_sync_read.cpp.

bool GroupSyncRead::getError	(	uint8_t	id,
		uint8_t *	error
	)

Definition at line 124 of file group_sync_read.cpp.

int GroupSyncRead::txPacket ( )

The function that transmits the Sync Read instruction packet which might be constructed by GroupSyncRead::addParam function.

Returns: COMM_NOT_AVAILABLE; when the list for Sync Read is empty; when the protocol1.0 has been used; or the other communication results which come from PacketHandler::syncReadTx

Definition at line 113 of file group_sync_read.cpp.

int GroupSyncRead::txRxPacket ( )

The function that transmits and receives the packet which might be come from the Dynamixel.

Returns: COMM_NOT_AVAILABLE; when the protocol1.0 has been used; COMM_RX_FAIL; when there is no packet recieved; COMM_SUCCESS; when there is packet recieved; or the other communication results which come from GroupBulkRead::txPacket or GroupBulkRead::rxPacket
