Method Detail

addReceivedPDO

@Command
public void addReceivedPDO(int cobId)

Description copied from interface: CanOpenInterface

Configures the pdo with the given cob_id for reception on the master node.

Specified by:

addReceivedPDO in interface CanOpenInterface

init

@Command
public void init(int master,
                          String baud,
                          String busName,
                          int nodeID)

Description copied from interface: CanOpenInterface

Initialization of the master node. This command has to be issued first for the subsequent one to be successful.

Specified by:

init in interface CanOpenInterface

Parameters:

master - 1 for master, 0 for slave.

baud - "125K","1M",...

busName - the bus name (0 for can0, 1 for can1)

nodeID - the nodeID

setEmergencyMessageListener

public void setEmergencyMessageListener(EmergencyMessageListener eml)

Specified by:

setEmergencyMessageListener in interface CanOpenInterface

setBootMessageListener

public void setBootMessageListener(BootMessageListener bml)

Specified by:

setBootMessageListener in interface CanOpenInterface

sync

@Command
public PDOData sync()
                      throws org.lsst.ccs.drivers.commons.DriverException

Sends a sync message on the canbus and synchronously waits for the received pdo configured in the master to be received. For it to work, all received pdos configured on the master node must have a transmission type equal to Ox1, otherwise the behaviour is undefined.

Specified by:

sync in interface CanOpenInterface

Returns:

The PDOs

Throws:

org.lsst.ccs.drivers.commons.DriverException

scan

@Command
public int scan()

Description copied from interface: CanOpenInterface

Sends a scan on the can bus.

Specified by:

scan in interface CanOpenInterface

Returns:

info

@Command
public String info(int nodeID)
                     throws org.lsst.ccs.drivers.commons.DriverException

Description copied from interface: CanOpenInterface

Returns the information for the given nodeID.

Specified by:

info in interface CanOpenInterface

Parameters:

nodeID - the node id

Returns:

Throws:

org.lsst.ccs.drivers.commons.DriverException

wsdo

@Command
public void wsdo(int nodeId,
                          int index,
                          int subindex,
                          int size,
                          long data)
                   throws org.lsst.ccs.drivers.commons.DriverException

Specified by:

wsdo in interface CanOpenInterface

Parameters:

nodeId - the node id

index - the index

subindex - the sub index

size - the size

data - the data

Throws:

org.lsst.ccs.drivers.commons.DriverException

Description copied from interface: CanOpenInterface

Read device entry

Specified by:

rsdo in interface CanOpenInterface

Parameters:

nodeId - the node id

index - the index

subindex - the subindex

Returns:

an unsigned long. Cast to int to treat it as signed, leave to long to treat it as unsigned
