The reference image includes multiple sample applications that allow
you to experiment and see how various features run.
By default, the reference image only starts the Sensor service with a
configuration of data files and camera files. The Car Creek MRB is
used for central processing capabilities. Generally, it's a good platform to
use to publish data. For example, you can run the Sensor example application
to demonstrate how to publish data.
To do this, you must connect to the reference image using
an
ssh connection and run the command to run the
application. These are the sample applications that demonstrate what you can build
with the
QNX Platform for ADAS:
Note: The applications are for demonstrative/reference purposes and are meant
as a starting point for you to learn how to build your
applications. They aren't intended for production and the code is
structured in a manner to make it easier to learn how to use the API
rather than being coded for efficiency.
Note: You can run multiple applications that use the same sensor
as long as you don't exceed the number
of connections supported for client applications.
For example, you could run multiple instances of the
Sensor example application and use the same sensors without issue.
For more information about the maximum connections supported by client applications,
see the Sensor Developer's Guide and
Camera Developer's Guide.
- Publish Subscribe example: This application runs
as either a publisher, subscriber, or both. This example uses
Platform-independent Publish Subscribe (PiPs).
For more information about using the application,
see “Publish and Subscribe example.”
- Robot OS example: This application can be used
to publish data that's read from connected sensors.
You can run a separate subscribe that listens for data
that's published and visualize the data on a separate host system.
For more information, about using this application, see
see “Robot OS example.”
- Sensor example: This application
reads sensor data, queries a sensor for information, and
queries that data. You can also use it to record sensor information.
For more information about using the application,
see “Sensor example.”
