8. Setting up a Slideshow
We have created a document and included tools for creating your own slideshows for EZ GUI units. Production
module units require 24-bit uncompressed Targa (.TGA) format for all images. Development kit units require bitmap
(.BMP) format for all slideshow images.
https://www.teamfdi.com/wp-content/uploads/Converting-a-PowerPoint-Slideshow-for-use-on-uEZGUI-Products-
.zip
This guide also covers making speaker notes that can play alongside your slides.
9. Setting up a Video
Suggested procedures on creating videos for playback using the µEZ video player provided in µEZ v2.05 (and later) on
supported µEZ GUI hardware, is available in the FDI Video Creation Guide (link below). This guide also suggests basic
procedures for downloading videos from YouTube.
This guide assumes that a source video is available in AVI uncompressed format with a resolution of 480×272 or
greater.

10. µEZ Doxygen online HTML documentation
μEZ has built-in comment documentation that follows the Doxygen comment standard. This standard writes code
comments and annotations in a certain manner so that it is compiled along with source code into HTML
documentation.
FDI provides pre-compiled HTML documentation at this link: http://www.teamfdi.com/uez/docs/
In the µEZ 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 updates the documentation periodically. We recommend reviewing your device for updates to the
documentation as you learn a new μEZ® release or drivers are added to the system.
For more information, see the Doxygen website: http://www.stack.nl/~dimitri/doxygen/
11. µEZ Bootloader
The uEZ bootloader allows users to install their own applications without the need for special tools like Jlink. All that
is needed is an SD card or USB drive. The bootloader consists of two primary components: The Base Bootloader
(BBL), which contains a base set of functions and never changes, and the Application Bootloader (ABL) that contains
the intelligence needed to program internal and external flash memory and can be updated dynamically since it is
loaded from local memory such as an SD card or USB drive.
Each time the unit is powered on or reset, the BBL will look to see if an application is already installed, and if so,
control is passed to the ABL which then launches the application. If no application is found, the BBL will search for the

µEZ GUI User’s Manu al

Revision 1.2
necessary files on an SD Card or USB drive, and if found, installs the ABL before passing control to it so the application
may be installed and booted. If no application and no SD card/USB drive are found, the user is prompted to install an
SD card/USB drive with the appropriate files.
The demo kit comes with an 8GB SD card on which are several demos for the user to try out. Out of box, the uEZGUI
comes preinstalled with a unique ‘bootloader application’that allows the user to select one of these demos to install.
The uEZ bootloader can be configured using the file named INSTALL.INI located in one of the demo applications’
folders. When “rename=true”, and after an application is installed, the file INSTALL.INI in the root of the SD card is
renamed to INSTALL.FIN, which when viewed by the uEZ bootloader, will indicate that the application installation is
final. At this point, every time the uEZGUI is powered on or reset, the bootloader will boot to the installed
application.
This can be undone by renaming the INSTALL.FIN file back to INSTALL.INI. Doing so will allow the uEZ bootloader to
boot back to the demo selection screen and permit the user to install a different application.
12. µEZ Project Maker
FDI has provided a project maker to help create new projects for EZ GUI hardware. It is available for download at
http://sourceforge.net/projects/uez/.
To create a new project, download the application, run the executable file, and follow the onscreen instructions. It
will create a demo project using an emWin example GUI that will provide 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 EZ GUI hardware using the included J-Link debugger, with no extra project configuration
necessary.
13. 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)

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.
μEZ®is ideally suited for Embedded Systems with standard features such as:
•Processor and Platform BSPs
(Board Support Packages)
•Real Time Operating System (RTOS)
•Memory Management
•NAND/NOR Flash
•SDRAM and DDR Memory
•TCP/IP stack
•USB Device/Host Libraries
•Mass Storage Devices
•LCD Displays with Touch Screen
•Input / Output Devices
14. Configuring Micro SD Card for High Clock Frequency
The LPC4357 can run the High-Speed SD Card Interface at a much higher speed, and the software is configured by
default to do so. The cards should be of good quality and have at least a class 10 rating. Below are some examples of
cards that FDI has tested and qualified.
•Kingston SDC10G2/16GBSP
•Kingston SDCA10/16GBSP

WARNING: The microSD card must only be removed using the spring loaded “push-pull” mechanism on the microSD
socket. Improper forceful removal of the microSD card will result in permanent damage to the socket that is not
covered under warranty. To insert the card, just push it into the socket until a “click” sound is heard.
Start with the microSD card in this position relative to
the microSD slot with the text and “lip” facing up.
Next gently insert the card partially into the socket.
Use your figure to gently push the card into the socket
until it clicks.
At this point the microSD card is fully inserted. It should not
fall out, even if the unit is shaken vigorously.
To remove the microSD card, press the card back into the socket until another “click” sound is heard, then release
pressure on the card. At this point, the card should be partially ejected from the socket. Finally grab the card and
gently pull to remove it. See the following pictures for proper micro-SD removal:
To remove the microSD card, gently push it into the
socket again until it “clicks”, and then release your figure.
