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:
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).

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.

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.
