The source code is freely available on the github repository: https://github.com/SoMLabs/imx_android_visionsom_8mm_demo_app. In the Android system image for SoMLabs modules this application is available by default, as stated in this tutorial: [[VisionSOM_imx-android|VisionSOM imx-android]]. In the image, this application is built as the system app.<br /> <br /> == User interface ==<br /> <br /> The application&#039;s GUI contains two buttons for enabling and disabling on-board LEDs, VideoView widget and a slider changing the text displayed on the label below.

It has access to the two LEDs brightness files defined in the sepolicy:<br /> <br /> &lt;pre&gt;<br /> /sys/devices/platform/leds/leds/LED-IO-04/brightness u:object_r:led_control:s0<br /> /sys/devices/platform/leds/leds/LED-IO-05/brightness u:object_r:led_control:s0<br /> &lt;/pre&gt;</div>
