Course Description:
Increasingly, embedded systems incorporate graphical displays and touch screens to create a rich man-machine interface. Linux, of course, has the capability to display complex graphics as anybody who has seen Linux running on a desktop PC will know. But, graphical environments are memory-hungry and can easily eat up hundreds of MB of RAM and storage. This course describes the architecture of graphical environments on Linux, especially the X windows system, and shows how to create optimised systems that are suitable for embedded use. Topics include X servers, frame buffers, programming environments, the GTK+ and Qt widget libraries.

Overview:
A three-day course, providing hands-on experience of configuring and programming graphical environments on Embedded Linux. Practical sessions use the Nokia 770 web pad.

Course Objectives:
After completing the course attendees will:
• Understand how to include complex graphical interfaces in small memory embedded systems
• Be able to cross-compile and load X on a typical target board
• Understand the architecture of X, frame buffers and window managers
• Have an overview of graphics programming libraries

Prerequisites:
• Good knowledge of ‘C’ or C++
• Some knowledge of Linux is an advantage

Who Should Attend:
Application programmers and software engineers who need to build a graphical user interface on Linux
