class mrpt::hwdrivers::CEnoseModular

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

Implemented for the Mdular board v1.0 designed by 2013 @ MAPIR (University of Malaga).

Construction

CEnoseModular()

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()”.

Methods

bool getObservation(mrpt::obs::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 doProcess()

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.

void setSerialPort(const std::string& port)

If not an empty string, will open that serial port, otherwise will try to open USB FTDI device “m_usbSerialNumber” The default is an empty string.

Example strings: “COM1”, “ttyUSB0”, …

void setSerialPortBaud(unsigned int baud)

Set the serial port baud rate (default: 115200)
