# Sample automotive applications
|
|
|
|
This directory contains a set of applications that demonstrate how
|
|
typical automotive applications use SOME/IP to talk to each
|
|
other. These apps work both natively and in a container, as
|
|
demonstated by the container sample image [described
|
|
here](https://sigs.centos.org/automotive/building/containers/).
|
|
|
|
## The apps
|
|
|
|
### engine-service
|
|
|
|
This is a very simple service with a single event that signals that
|
|
the car is reversing, which is regularly emitted.
|
|
|
|
### radio-service
|
|
|
|
This is a service that emulates a radio, regularly publishing
|
|
information about the current song, radio station and volume. It
|
|
accepts requests to turn on/off, switch channel, and change volume.
|
|
If the engine service is available it will listen for events from it
|
|
and temporarily lower the volume while reversing.
|
|
|
|
### radio-client
|
|
|
|
This is a command line program that displays the current state of the
|
|
radio service, as well as allow you to control it. The keyboard controls
|
|
are displayed on the screen.
|
|
|
|
## Building
|
|
|
|
The apps depend on boost and vsomeip3, and can be build with cmake like this:
|
|
|
|
```
|
|
$ cmake .
|
|
$ make
|
|
```
|
|
|
|
There is also a makefile that allows building rpms and srpms:
|
|
|
|
```
|
|
$ make -f Makefile.rpm srpm
|
|
$ make -f Makefile.rpm rpm
|
|
```
|
|
|
|
These rpms, in addition to required dependencies (dlt-daemon,
|
|
vsomeip3) are pre-build for cs9 it in [this copr
|
|
repo](https://copr.fedorainfracloud.org/coprs/alexl/cs9-sample-images/packages/).
|
|
|
|
Additionally, there is a
|
|
[Containerfile.auto-apps](Containerfile.auto-apps) file that allows
|
|
installing these apps into a container, using the above rpms. You can
|
|
build it like this:
|
|
|
|
```
|
|
$ podman build -f Containerfile.auto-apps
|
|
```
|
|
|
|
Or use the Makefile.container helpers:
|
|
|
|
```
|
|
$ make -f Makefile.container build
|
|
```
|
|
|
|
A pre-built version of these containers for aarch64 and x86-64 is
|
|
available in the [automotive sig container
|
|
repo](https://gitlab.com/CentOS/automotive/sample-images/container_registry/2944592).
