D5 Embedded GUI

Graphical User Interfaces for Embedded Linux


Objectives
	Understand the different layers associated with the graphic interface system
	Learn how to use the Linux frame buffer
	Discover the hardware abstraction layers
	Learn to use the main graphical toolkits (widgets) taretting embedded Linux
		QT
		FLTK
		WxEmbedded
		MiniGUI
		...

	Learn how to link commands to GUI elements
Labs are conducted on target boards, that can be:
Dual Cortex/A9-based "SnowBall" boards from ST-Ericsson, with Lauterbach JTAG probes.
Atmel ARM9-based boards, with Lauterbach JTAG probes.
We use the last linux kernel, as delivered on www.kernel.org.


Hardware
	A Linux PC for two trainees, with an ARM based target board
	Course material
	CDROM with documentation and tools used during the trainin


Prerequisites
	Knowledge of Linux user level programming (see our D0 course)
	Knowledge of embedded Linux (see our D1 course)

Outline


The various system layers used by GUIs
	Kernel drivers: frame buffer, direct access, ...
	Hardware abstraction layers: X, GGI, DirectFB, ...
