The expected format of a single valued message is:
-{% highlight javascript %}
-{"name": "steering_wheel_angle", "value": 45}
-{% endhighlight %}
+ {"name": "steering_wheel_angle", "value": 45}
## Evented
The expected format of an event message is:
-{% highlight javascript %}
-{"name": "button_event", "value": "up", "event": "pressed"}
-{% endhighlight %}
+ {"name": "button_event", "value": "up", "event": "pressed"}
This format is good for something like a button event, where there are two
discrete pieces of information in the measurement.
