====== Running the Delta Application ======
Next, ssh into the target. Before you start the delta application you have to make sure that your mouse works with		<code>
ost@bblue:$ sudo cat /dev/input/event1	 
</code>	 
Start your application in a second terminal while the above command is still running	 
<code>
ost@bblue:$ sudo ./bin/delta -c bin/HwConfigBBBlue.json
</code>


===== Autostart =====

Usually you want run the application upon startup of the board after you applied power.
For this purpose you have to copy two files from the //bbblue-scripts// folder of [[https://github.com/eeduro/eeduro-scripts|]] to your target:
<code>
$ scp ./bbblue-scripts/start.sh ost@192.168.7.2:bin
$ scp ./bbblue-scripts/delta-startup.service ost@192.168.7.2:bin
</code>
Make sure that ''start.sh'' is executable on the target. ssh into the target and run:
<code>
ost@bblue:$ chmod +x bin/start.sh 
</code>
Further, copy the file ''delta-startup.service'' to the right location, so that your systemd can find it upon initialization.
<code>
ost@bblue:$ sudo mv bin/delta-startup.service /etc/systemd/system/
</code>
As a final step you have to enable the service with
<code>
ost@bblue:$ sudo systemctl enable delta-startup
</code>
and reboot with
<code>
ost@bblue:$ sudo /sbin/reboot
</code>
Now, the Delta application will start 20s after the board is powered up and the operating system finished its bootup procedure. When the Delta application terminates the Beaglebone Blue will shutdown after 30s. You can terminate the application as described in [[user_interface|]].

:!: Please note that upon termination of the program the BeagleBoneBlue will shutdown and you will loose your ssh connection.

===== Get Output of Loggers after Autostart =====
The Delta application periodically logs various state information. To see this output the application was started in a detached screen. To see the log output from the application just reattach to this screen session. First connect to your target with 
<code>$ ssh ost@192.168.7.2</code>
then reattach with
<code>
ost@bblue:$ sudo screen -r delta
</code>
You could also terminate the application by pressing ''CTRL-C''. \\

:!: Please note that upon termination of the program the BeagleBoneBlue will shutdown and you will loose your ssh connection.
