Member Function Documentation

bool ULms100::changeMode	(	int	scanangle,
		double	resolution
	)

virtual

Change scanner resolution mode. Returns true if new resolution is set

Reimplemented from ULaserDevice.

References ULaserDevice::angleResolution, mini(), and ULaserDevice::modeAngleScan.

void ULms100::closePort ( )

protectedvirtual

Close serial port

Reimplemented from ULaserDevice.

References UClientPort::closeConnection(), ULock::lock(), toLog(), and ULock::unlock().

Referenced by isLms100(), and ~ULms100().

char * ULms100::decodeData	(	char *	msg,
		UTime	rxTime
	)

protected

Decode message from laserscanner. Handles all received messagetypes, and stores result as appropriate.

Parameters

msg	is a 0 terminated string (but may have binary parts). Intial STX and terminating ETX is removed.
rxTime	is time-stamp just after start of receive

Returns: pointer to the first unused character. This may be the same as 'msg', as 'msg' may be part of a message only.

bool ULms100::decodeName ( char * msg )

protected

Decode name message

References MAX_DEVICE_NAME_LNG, and ULaserDevice::name.

Referenced by isLms100().

bool ULms100::getDataTo	(	char *	msg,
		ULaserData *	dest
	)

protected

Decode this 'msg' data to the 'dest' structure.

Parameters

here expected to be a bit more than half a scan-time (at 50 scans per second)

Reimplemented from ULaserDevice.

const char * ULms100::getNameFromDevice ( )

protectedvirtual

Get name of device

Reimplemented from ULaserDevice.

References ULaserDevice::getName().

Referenced by isLms100().

bool ULms100::receiveData ( )

protectedvirtual

Receive data from device – called from device loop, should return as fast as possible after doing the job, i.e. no blocking read. Should add number of good and bad blocks of data to statBadCnt and statGootcnt. Returns true if data received.

Reimplemented from ULaserDevice.
