sudo java -jar pixel.jar
In the above command, 'pixel.jar' should be replaced with the actual name of the JAR file copied to the Raspberry Pi.
There are some command line switches to configure the application. See below for details.
Once the Java application is running from the command line, a bunch of lines scroll on the terminal showing connection messages. If it is the first run, then image resource extraction messages are also shown.
Next, visit the following URL.
http://raspberrypi:8080/files/index.html
The 'raspberrypi' in the above URL should be replaced with the host name (or IP address) of computer running the Pixel Web applicaton.
At the above URL, a user interface is presented with a drop down menu to change between Pixel modes.
Scrolling Text
The scrolling text mode lets you enter some text, change scroll speed, and specify text color.
Displaying Stills and Animations
Still image mode presents the various images available for drawing on the Pixel.
Animations mode similarly presents the various animations available.
On the user interface for still and animated images, a 'Display' button is used to select what is shown on the Pixel's RGB LED matrix.
Uploads for User Supplied Animated GIFs and Still Images
The user can upload their own still images and animated GIFs. The file chooser button is used to select a still or animated GIF, on the filesystem. Then click the upload button and it should appear in the corrosponding animated or still image list.
Save Animations to SD Card
In offline mode, an animation can be played from the SD card onboard the PIXEL. This means you can still have an animation play even if the Web enabled application is not running.
Use the 'Save' button to write an animation to the SD card for offline use.
