Detailed Description

A class for interfacing an e-Noses via a FTDI USB link.

Implemented for the board v1.0 designed by 2007 @ ISA (University of Malaga).

Constructor & Destructor Documentation

mrpt::hwdrivers::CBoardENoses::CBoardENoses ( )

Constructor.

Parameters:

serialNumberUSBdevice

The serial number (text) of the device to open. The constructor will try to open the device. You can check if it failed calling "isOpen()".

virtual mrpt::hwdrivers::CBoardENoses::~CBoardENoses ( ) [virtual]

Destructor.

Member Function Documentation

bool mrpt::hwdrivers::CBoardENoses::checkConnectionAndConnect ( ) [protected]

Tries to connect to the USB device (if disconnected).

Returns:: True on connection OK, false on error.

void mrpt::hwdrivers::CBoardENoses::doProcess ( ) [virtual]

This method should be called periodically (at least at 1Hz to capture ALL the real-time data) It is thread safe, i.e.

you can call this from one thread, then to other methods from other threads.

Implements mrpt::hwdrivers::CGenericSensor.

bool mrpt::hwdrivers::CBoardENoses::getObservation ( mrpt::slam::CObservationGasSensors & outObservation )

Request the master eNose the latest readings from all the eNoses.

The output observation contains a valid timestamp and 3D positions if "loadConfig" has been called previously.

Returns:: true if OK, false if there were any error.

virtual void mrpt::hwdrivers::CBoardENoses::initialize ( ) [virtual]

Tries to open the camera, after setting all the parameters with a call to loadConfig.

Exceptions:

This

method must throw an exception with a descriptive message if some critical error is found.

Reimplemented from mrpt::hwdrivers::CGenericSensor.

void mrpt::hwdrivers::CBoardENoses::loadConfig_sensorSpecific	(	const mrpt::utils::CConfigFileBase &	configSource,
		const std::string &	section
	)			`[protected, virtual]`

Loads specific configuration for the device from a given source of configuration parameters, for example, an ".ini" file, loading from the section "[iniSection]" (see utils::CConfigFileBase and derived classes) See hwdrivers::CBoardENoses for the possible parameters.

Implements mrpt::hwdrivers::CGenericSensor.

bool mrpt::hwdrivers::CBoardENoses::queryFirmwareVersion ( std::string & out_firmwareVersion )

Query the firmware version on the device (can be used to test communications).
