class mrpt::hwdrivers::CGenericSensor

A generic interface for a wide-variety of sensors designed to be used in the application RawLogGrabber.

Derived classes should be designed with the following execution flow in mind:

  • Object constructor

  • CGenericSensor::loadConfig : The following parameters are common to all sensors in rawlog-grabber (they are automatically loaded by rawlog-grabber) - see each class documentation for additional parameters:

    • “process_rate”: (Mandatory) The rate in Hertz (Hz) at which the sensor thread should invoke “doProcess”.

    • “max_queue_len”: (Optional) The maximum number of objects in the observations queue (default is 200). If overflow occurs, an error message will be issued at run-time.

    • “grab_decimation”: (Optional) Grab only 1 out of N observations captured by the sensor (default is 1, i.e. do not decimate).

  • CGenericSensor::initialize

  • CGenericSensor::doProcess

  • CGenericSensor::getObservations

Notice that there are helper methods for managing the internal list of objects (see CGenericSensor::appendObservation).

Class Factory: This is also a factory of derived classes, through the static method CGenericSensor::createSensor

Construction

CGenericSensor()

Methods

virtual void doProcess() = 0

This method will be invoked at a minimum rate of “process_rate” (Hz)

Parameters:

This

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