We are going to turn pcDuino into a digital picture frame.

The thing to make this magic happen is a tool called fbi: frame buffer interface.

To install the Linux Frame Buffer Interface using:  $sudo apt-get install fbi.

To show the pictures, use the following command:

$sudo fbi -noverbose -m 1920x1080 -a -T 2 -t 10 *.jpg

The mode supported by ‘-m’ can be found at:

$more /etc/fb.modes

The switch ‘-T” means that displaying the pictures to HDMI, i.e., ‘-T 2′.
‘-a’ means that it will automatically fit the picture into the screen.
‘-t’ is the interval to change to picture.
