 GUI Products
PEG+™
A graphical interface development package designed exclusively for real-time
embedded systems. The tools you expect, the support you need, the quality and
reliability your project demands.
|
PEG WindowBuilder™, shown at right, is a complete visual layout and
design tool included with PEG+. The output of PEG WindowBuilder is
EC++ source code, ready to be compiled and linked into your ROM or
FLASH. PEG WindowBuilder is written entirely using the PEG+ library,
allowing it to run on all Windows and Linux/X11 development hosts. |
|
Custom user-supplied control types can easily be incorporated within
the PEG WindowBuilder environment, allowing you to create completely
unique screen designs using these WYSIWYG design tools. Custom
graphics and fonts are also incorporated into your PEG WindowBuilder
project, allowing you to do complete and accurate screen design using
simple drag-and-drop techniques.
The default appearance of PEG+ windows and controls is similar to
the appearance of a desktop windowing system. This appearance can,
of course, be modified to create a completely custom look-and-feel.
The window shown at right demonstrates the use of a custom title bar,
custom button style, shadowed anti-aliased text and bitmap animation
objects. PEG+ graphics can also be overlaid on real-time video or alpha
blended using multiple graphical layers. The library is easily configured for
an infinite variety of display resolutions, orientations and color depths.
Anti-aliased fonts and anti-aliased line drawing are supported for high-color
depth targets. Industry leading multi-lingual application support
includes full Unicode and SJIS character encoding support, and string
table editing and language pack generation facilities incorporated into the
StringTableEditor as a part of the WindowBuilder resource manager.
Summary
PEG+ provides the most complete GUI solution available to realtime emedded
system developers. All of the utilities, documentation, support and development
tools you will require for creating a graphical user interface on an embedded
system are included with the PEG+ library development package.
Features
Reduced Size
PEG+ is written with the embedded market firmly in mind, meaning that the value
of every feature is weighed against the code size and performance requirements
of that feature. A minimum PEG+ footprint requires roughly 150K of code space,
4K of stack space and 8K of dynamic memory. A typical full-featured GUI requires
a PEG+ footprint of roughly 170K code, 4K stack and 16K dynamic memory.
RTOS Integration
PEG+ is fully integrated with the RTOS messaging, memory management and synchronization
services. This yields the lowest possible overhead and the only true
real-time multitasking GUI environment available. PEG+ input devices are interrupt
driven, and again use RTOS services to communicate user input information
to the graphical user interface.
Multiple Tasks
PEG+ can also be configured to support multiple GUI tasks. These tasks can be of differing
priorities and can each directly create, display and control any number of GUI
windows or child controls. This advanced capability is unique to the design of PEG+.
Microsoft Windows Development
PEG+ provides a set of hardware and OS encapsulation classes which allow your
PEG+ user interface to run as a standard 32-bit Windows application. You can
create and test your entire user interface while using the very mature Windows
application development tools. Moving to the final target requires only that you
rebuild the PEG+ library and application software using your target specific tools.
X11 Development
PEG+ also provides an X11 Window System integration that allows your PEG+
application to run as a standard X11 application. Most major Unix platforms are
supported including Linux, Lynx OS, NetBSD and Solaris. The PEG+ development
tools are also X11 hosted, allowing you to do full application development and
testing using this alternative host environment.
Compiler Support
The PEG+ library has been fully verified with all of the most popular embedded
compilers including Green Hills MULTI, Metrowerks CodeWarrior, MetaWare,
IAR, CAD-UL, ARM RealView, Borland, Microsoft, Hitachi, ST Microelectronics,
Paradigm, Watcom, GCC, Tasking, TI Code Composer, Analog Devices Visual DSP,
Microtec C/C++, and Keil µVision2.
Input Devices
PEG+ can be configured to support any combination of mouse, keyboard, touch
screen or membrane keypad input.
Output Drivers and Processor Support
See the PDF datasheet for a list of video drivers and processors supported.

The PEG+ Package
PEG+ includes a large set of basic control
types such as various buttons, text gadgets
and bitmap display objects. PEG+ also
includes more advanced classes such as
tree-view, spreadsheet and charting classes.
In addition, PEG WindowBuilder provides an integrated resource manager which includes FontCapture for generating custom fonts and ImageConvert for converting PNG, JPG, GIF or BMP graphics into ROMable format supported by the PEG+ library. Advanced
color reduction, dithering and optimal
palette production can be applied to assist
those running on greyscale, monochrome
or limited palette targets. Rotated screen
mounting is also seamlessly supported.
