Revision 3.1
Draw
A very simple art program is provided. Use the touch screen to draw lines in the box to the right. Clicking on Color
allows the color to be changed between various options. Hint –use black to erase. Save stores the graphic image as
the file IMAGE.RAW on the Micro SD card. Load recalls the saved graphic image from the Micro SD card.
emWin Demo
If present, this runs a demonstration of various emWin graphical demos.
See http://www.segger.com/emwin.html for more details.
This example is available here for reference:
http://www.segger.com/emwin-samples.html
7. Setting up a Slideshow
The Slideshow demonstration loads and scrolls between images provided on a micro SD card. Images must be in 24
bit uncompressed Targa (.TGA) format. Adobe Photoshop and many other graphics programs can save images in this
format. The images must be 480x272 in resolution and use the file names WQSLIDExx.TGA where xx is 00 thru 99.
(i.e. WQSLID01.tga, WQSLID02.tga, etc).
Images must be stored in a directory under /SLIDES. Edit the file “SLIDES.TXT” by adding a line in the following
format: “<title>,<directory>”. The field <title> is the text shown when selecting a slideshow. The field <directory> is
the subdirectory in which the slides are found. The field <directory> must be 8 characters or less.
NOTE: Currently, the uEZ GUI will only allow selection of the top four entries of “SLIDES.TXT”.
Place the pictures created above in the subdirectory listed in the “SLIDES.TXT”file. For example, entry “uEZGUI-
4088-43WQN,UEZGUI” puts up a title of “uEZGUI 4088-43WQN” and loads the slides (WQSLID01.TGA to
WQSLID09.TGA) from the directory /SLIDES/UEZGUI.
8. Setting up a Video
Refer to the “uEZ Video Conversion Guide” for details on converting a video for playback on a uEZGUI.
The guide covers the video conversion process, as well as how to setup the video files on a microSD card for playback
in the uEZ video player.
9. uEZ Doxygen online HTML documentation
μEZ®has built-in comment documentation that follows the Doxygen comment standard.
This standard allows for code comments and annotations to be written in a certain manner, and then compiled along
with source code into HTML documentation.
FDI provides the pre-compiled HTML documentation at this link: http://www.teamfdi.com/uez/docs/
In the uEZ source code, “uEZ/uEZDoxyfile” is the main project file for the Doxygen generator. When Doxygen is
recompiled, the new Doxygen files will be found here: uEZ\Docs\ Doxygen_Documentation.html

Revision 3.1
FDI will update the documentation roughly with each new μEZ® release or as new drivers are added to the system.
For more information, see the Doxygen website: http://www.doxygen.org/
10. uEZ Project Maker
FDI has provided a project maker to help create new projects for uEZGUI hardware.
The project maker is here and includes its own manual: http://www.teamfdi.com/uez/files/uEZ Project Maker.zip
This project maker can create demo projects using a very simple emWin example GUI, along with some basic
peripheral functionality. The project maker greatly speeds up the development process for new applications.
Example projects are ready to be compiled and programmed onto uEZGUI hardware using the included J-Link
debugger, with no extra project configuration necessary.

11. Software
μEZ®takes its name from the Muses of Greek mythology. A Muse was a goddess who inspired the creation process
for the arts and sciences. Like its ancient Greek namesake, the μEZ® platform inspires rapid development by
supplying customers with an extensive library of open source software, drivers, and processor support - all under a
common framework. μEZ®development works on the premise of ”design once, reuse many times”. This provides an
open source standard for embedded developers to build upon and support. μEZ®allows companies to focus on
innovation and on their own value-added applications while minimizing development time and maximizing software
reuse.
The diagram below shows a typical embedded application stack. μEZ® has three primary categories of components
that help simplify embedded application development:
1. Operating System Abstraction Layer (μEZ®OSAL)
2. Sub-system drivers (μEZ®TCP/IP, μEZ®USB, μEZ®Driver)
3. Hardware Abstraction Layer (μEZ®HAL)
Applications
µEZ®OSAL µEZ®TCP/IP
µEZ®HAL
Hardware Peripheral API
Embedded Microprocessor
µEZ®USB µEZ®DRIVER
FreeRTOSTM
Iwip Host Device
OTG
LCD
Touchscreen
File System
I2C, SPI, Etc.
The selection of an RTOS can be one of the most daunting aspects of an embedded system development. With μEZ®
the primary features of common multi-tasking operating systems are abstracted, thus easing the transition to an
open source or low-cost RTOS. The μEZ®OSAL provides applications access to the following features in an OS-
independent fashion:
Pre-emptive multitasking
Stack overflow detection
Unlimited number of tasks
Queues
Semaphores (binary, counting, mutex)
The μEZ®sub-system drivers utilize the OSAL functions to provide protected access to the processor
peripherals. The sub-system driver API functions are typically protocol layer interfaces (TCP/IP, USB, etc)
designed as high-level access routines such as open, close, read, write, etc. where possible.
