GUIX and GUIX Studio, Express Logic’s Development Tools Optimized for Small Footprint

GUIX™ is a high-performance real-time implementation of a (GUI) designed for embedded ThreadX-based applications. GUIX™ easily scales from small micro-controller-based applications to those that use powerful RISC and DSP processors, unlike other commercial implementations originally intended for workstation environments but then squeezed into embedded designs.
GUIX Studio™ is a Microsoft Windows-based rapid UI development environment specifically designed for the GUIX runtime library from Express Logic.

GUIX™ is a small-footprint, low-overhead runtime engine and development tool featuring automatic code generation for embedded systems capable of graphical display. GUIX™ is the latest product release from Express Logic, Inc., already known as the worldwide leader in royalty-free real-time operating systems (RTOSes). GUIX™ simplifies GUI development and targets the ARM 32-bit MCU and MPU architectures, including Cortex-M3, M4, A8, and A9, in medical devices, consumer electronics, and industrial control equipment.

GUIX™ includes a full-featured runtime graphical library fully integrated with ThreadX, Express Logic's popular RTOS that is deployed in over 2 billion devices. Like ThreadX, GUIX™ achieves high performance in small footprint, deeply embedded applications. Designed to meet the growing need for dynamic user interfaces with limited hardware resources. GUIX™ uses the same optimized design and coding methods of ThreadX and the other Express Logic embedded system software products, is distributed with full ANSI C source code, and has no run-time royalties.

Thanks to the explosion of opportunities that started in smartphones, GUIs have become commonplace in medical, consumer, and industrial applications, prompting the need for advanced tools to simplify their development. Most embedded system programmers are not LCD specialists and do not want to program these displays at the lowest level, which involves constructing individual graphical shapes and objects ("widgets"). Instead, to speed time to market, most developers use a library of routines that manage the GUI details. By describing the widgets at a high level, such libraries help developers to enhance programming productivity and avoid many errors. GUIX™ offers developers an advanced UI framework and rich library of unique widgets tailored to help them construct whatever GUI they envision. Programmers can call GUIX™ functions from their C application programs, and GUIX™ performs all the necessary drawing functions to produce a clear, interactive GUI on LCD screens of various sizes and resolutions.

GUIX Studio

GUI designers can create GUIs using GUIX Studio™, the companion PC-based application that enables WYSIWYG rapid prototyping of GUI designs. With GUIX™ Studio, the designer can select, drag-and-drop, and resize images, backgrounds, widgets, and other elements of a powerful GUI without having to write a single line of code. GUIX Studio™ generates the code necessary to implement the exact GUI design constructed on the PC. The generated code can be dropped into the application and executed on the target system.

A complete GUIX™ UI application can be executed on a PC desktop within the GUIX Studio™ environment, enabling developers or designers to quickly and easily generate and demonstrate UI concepts and test screen flows as well as observe screen transitions and animations. When completed, the design can be exported to target-ready C data structures that are ready to be compiled and linked with the GUIX™ and ThreadX libraries as part of a project.

Developers can produce prerendered fonts for their applications using integrated font generation in GUIX Studio™. Fonts can be generated in monochrome or antialiased formats that are compressed to save space on the target. Fonts can include any set of characters, including Unicode characters for multilingual applications. Importing graphics from PNG, JPG, or BMP files and converting them to compressed GUIX™ pixelmaps for the target system is another integrated feature of GUIX Studio™, and many of the GUIX™ widget types are designed to incorporate developers' proprietary graphics for a custom look and feel. In addition, developers can customize default colors and drawing styles used by the stock GUIX™ widgets, allowing them to customize the appearance of GUIX™ very easily. GUIX Studio also generates and maintains application strings for any number of target languages.

"The widespread appeal of the smartphone with its user-friendly GUI has revolutionized expectations of interactive devices not only in the consumer domain, but also for medical equipment and industrial control systems," noted Ken Maxwell, Director of GUI Engineering at Express Logic. "GUIX and GUIX Studio were conceived and developed to ensure that comparable GUI designs can be realized in embedded system GUIs for all markets."
