mrpt::hwdrivers::CNationalInstrumentsDAQ Class Reference

Detailed Description

An interface to read from data acquisition boards compatible with National Instruments "DAQmx Base" or "DAQmx".

Refer to DAQmx Base C API reference online to learn more on the concepts of "channels", "tasks" (which in this MRPT class are mapped to independent grabbing threads), etc. If both DAQmx and DAQmxBase are installed in the system, DAQmx will be used. This class API isolate the user from the usage of one or another specific library.

This class can be used as a sensor from the application "rawlog-grabber", or directly as a C++ class from a user program. Refer to the example: [MRPT]/samples/NIDAQ_test

Samples will be returned inside mrpt::obs::CObservationRawDAQ in "packets" of a predefined number of samples, which can be changed by the user through the "samplesPerChannelToRead" parameter of each task.

For multichannels tasks, samples will be interleaved. For example, the readings from successive timesteps for 4 ADC channels will be available in the ADC vector inside mrpt::obs::CObservationRawDAQ in this order:

• A0[0] A1[0] A2[0] A3[0] A0[1] A1[1] A2[1] A3[1] A0[2] A1[2] A2[2] A3[2] ...

The sensor label (field "m_sensorLabel") of each grabbed observation will be the concatenation of this class sensor label, a dot (".") and the task label (default="task###", with ### the task index).

DAQmx Base Installation

Go to http://ni.com and download the "DAQmx Base" package for your OS. Install following NI's instructions. As of 2013, the latest version is 3.7.

Note

This class requires compiling MRPT with support for "NI DAQmx" or "NI DAQmx Base". While compiling MRPT, check the "MRPT_HAS_NI_DAQmx"/"MRPT_HAS_NI_DAQmxBASE" option and correctly set the new variables to the library include directory and library file.

As of 2013, NI seems not to support compiling 64bit programs, so you can must build MRPT for 32bits if you need this class.

appendObservations()

void CGenericSensor::appendObservations ( const std::vector< mrpt::utils::CSerializablePtr > &  obj )

protectedinherited

This method must be called by derived classes to enqueue a new observation in the list to be returned by getObservations.

Passed objects must be created in dynamic memory and a smart pointer passed. Example of creation:

mrpt::obs::CObservationGPSPtr  o = CObservationGPSPtr( new CObservationGPS() );
o-> .... // Set data
appendObservation(o);

If several observations are passed at once in the vector, they'll be considered as a block regarding the grabbing decimation factor.

readFromDAQ()

void CNationalInstrumentsDAQ::readFromDAQ	(	std::vector< mrpt::obs::CObservationRawDAQPtr > &	outObservations,

	)

Receives data from the DAQ thread(s).

It returns a maximum number of one observation object per running grabber threads, that is, per each DAQmx "task". This method MUST BE CALLED in a timely fashion by the user to allow the proccessing of incoming data. It can be run in a different thread safely. This is internally called when using the alternative CGenericSensor::doProcess() interface. No observations may be returned if there are not samples enough yet from any task.

setPathForExternalImages()

virtual void mrpt::hwdrivers::CGenericSensor::setPathForExternalImages ( const std::string &  directory )

Set the path where to save off-rawlog image files (will be ignored in those sensors where this is not applicable).

An empty string (the default value at construction) means to save images embedded in the rawlog, instead of on separate files.

Exceptions

std::exception

If the directory doesn't exists and cannot be created.
