6. Startup procedure
The uEZ GUI kit comes with a pre-installed Micro SD card that contains files required for the slide show and
videos to run. It also contains users’ manuals, schematics, and documentation for the product.
Power is supplied via a USB cable and power supply provided in the kit. Connect the USB cable from the power
supply to (P2) the mini B USB connector labeled 5V 1A min input only. Note that the other USB connector (P1) is
for communications only and will not supply power to the unit. Also note that the minimum power requirement
is 1.0A so most USB power sources, which are limited to 500mA max, will not adequately power this unit.
The following screens should appear once power has been applied to the kit:
At this point the unit is ready for software demonstrations and user operation.
By connecting the USB A to mini B cable to P1, the uEZGUI will also appear as a USB Flash
Drive to the PC, allowing the user to read/write files directly to the Micro SD card.

8. Setting up a Slideshow
The Slideshow demonstration loads and scrolls between images provided on a SD micro 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 800x480 and 11.11”x6.67” in size and use the file names WVSLIDExx.TGA where xx is 00
thru 99. (i.e. WVSLID01.tga, WVSLID02.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 allows 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 “uEZGUI1788-70WVM,UEZGUI” puts up a title of “uEZGUI-1788-70WVM” and loads the slides (WVSLID01.TGA to
WVSLID08.TGA) from the directory /SLIDES/UEZGUI.
The Slideshow demonstration also allows for audio notes/narration to play back when a slide is shown.
To use this feature, create audio files for each slide that you wish to have narrated. The files should be 22.05 KHz
mono WAV files. Place the files inside the same directory as the slideshow. Each slide should have a corresponding
WAV file with the exact same name. For example, for a slide named WVSLID03.TGA, the corresponding audio file will
be named WVSLID03.WAV. During the Auto Play mode, the audio will be sync’ed with the slide progression and the
viewing time between transitions is controlled by the length of the audio clip for each slide.
9. 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.
10. 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
FDI will update the documentation roughly with each new μEZ® release or as new drivers are added to the system.

11. uEZ Project Maker
FDI has provided a project maker to help create new projects for uEZGUI hardware.
The project maker is included in the uEZ source code download package and includes its own user’s manual.
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.
12. 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)
Error! Objects cannot be created from editing field codes.
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 OSindependent 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.

μEZ® is ideally suited for Embedded Systems with standard features such as:
 Processor and Platform BSPs
 TCP/IP stack
(Board Support Packages)
 USB Device/Host Libraries
 Real Time Operating System (RTOS)
 Mass Storage Devices
 Memory Management
 LCD Displays with Touch Screen
 NAND/NOR Flash
 Input / Output Devices
 SDRAM and DDR Memory

P2 – USB Power Input 5VDC
The uEZGUI-1788-70WVM is normally powered via P2 with the included 5V USB Wall Supply. This power
supply is only included in the development kit and is not included with the uEZGUI-1788-70WVM-BA. Note
that the other USB connector (P1) is for communications only and will not supply power to the unit. Also
note that the minimum power requirement is 1.0A so most USB power sources, which are limited to 500mA
max, will not adequately power this unit.

Power Requirements
Power is supplied into the power-only USB connector (P2) via a power supply provided in the kit. The power supply
provides 5VDC output at 1.2A (min) and has input voltage range of 100-240VAC with standard U.S. 2-prong plug. The
following typical power requirements were measured at room temperature with LPC1788 at 120MHz clock rate:
Voltage
5V
Booted at the uEZ Demo Screen
790 mA
Observed Max (video playback)
880 mA
The following measurements were taken with a GainSpan GS1011MIP Wi-Fi module loaded on the board and turned
on and connected to an access point.
Voltage
5V


Observed Max (Wi-Fi & video)
1100 mA
Maximum allowed
Up to 2A through uEZGUI power connectors
The uEZGUI is capable of providing a maximum of 100mA of 3.3V power for “external use” over the
expansion connectors. If more than 100mA of 3.3V is needed for an expansion board:
o Then the primary power input (i.e. 5V) should be located on the expansion board rather than on the
UEZGUI.
o The expansion board should be designed with a separate 3.3V voltage regulator.
o Ensure the 3.3V voltage rails of the uEZGUI & Expansion Board are not connected together.
o The uEZGUI should be powered using 5V from the Expansion Board over the 70 pin breakout, instead
of powering the Expansion Board from the uEZGUI unit.
The uEZGUI-1788-70WVM may also optionally be powered via the following connectors;
o Alternate Power/Communication Connector, J11, with a maximum of 2A 5V input
o Expansion Connector(s) J4 and/or J5 – refer to the expansion connector section for details
