D5 Embedded GUI

Graphical User Interfaces for Embedded Linux

Graphical User Interfaces for Embedded Linux
  • 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:
    Atmel ARM9-based boards, with Lauterbach JTAG probes.
We use the last linux kernel, as delivered on

Labs are conducted using the System Workbench for Linux - Basic Edition IDE.

  • A Linux PC for two trainees, with an ARM based target board
  • Course material
  • CDROM with documentation and tools used during the trainin
  • Theoretical course
    • PDF course material (in English) supplemented by a printed version.
    • The trainer answers trainees' questions during the training and provide technical and pedagogical assistance.
  • At the start of each session the trainer will interact with the trainees to ensure the course fits their expectations and correct if needed
  • Any embedded systems engineer or technician with the above prerequisites.
  • The prerequisites indicated above are assessed before the training by the technical supervision of the traineein his company, or by the trainee himself in the exceptional case of an individual trainee.
  • Trainee progress is assessed by quizzes offered at the end of various sections to verify that the trainees have assimilated the points presented
  • At the end of the training, each trainee receives a certificate attesting that they have successfully completed the course.
    • In the event of a problem, discovered during the course, due to a lack of prerequisites by the trainee a different or additional training is offered to them, generally to reinforce their prerequisites,in agreement with their company manager if applicable.
