嵌入式GUI的种类
Open source Embedded Linux Graphics System Software
--------------------------------------------------------------------------------
Dillo -- Dillo is a very small (less than 300KB), fast, Open Sourcemulti-platform web browser that's written completely in C and built onGTK+ libraries. Dillo's high efficiency and minimal librarydependencies make it quite suitable for embedded apps. Dillo can beteamed up with an embedded webserver to completely eliminate the needfor a window manager in an embedded device.
DirectFB -- DirectFB is a thin library that provides developers withhardware graphics acceleration, input device handling and abstraction,integrated windowing system with support for translucent windows andmultiple display layers on top of the Linux Framebuffer Device. It is acomplete hardware abstraction layer with software fallbacks for everygraphics operation that is not supported by the underlying hardware.
The Familiar Project -- this open source PDA Linux project, which is anoffshoot of the activities at handhelds.org, has collected together allof the key components of a complete Linux-based PDA computing platform.The Familiar distribution currently includes a Blackbox-based windowmanager, Agenda Computing's Fltk+ based PIM applications, an embeddedPython implementation, system configuration and settings backuputilities, OpenSSH client and server, and a Debian-based ARM kernel.
FBUI -- FBUI is a tiny GUI that resides inside the Linux kernel. Thekey concepts of FBUI are that firstly it is small; secondly that it isspartan, which is good; thirdly that it is just another driver; andfourthly that drivers belong in the kernel, not in userspace.
GGI project -- the "General Graphics Interface" project is dedicated todevelopment of fast, stable, open-source cross-platform multimedia APIsystems. Designed from the ground up with environments such as embeddedsystems in mind, GGI is fast, clean, abstract, dynamically modular andhighly optimizeable.
GPE Palmtop Environment -- this project aims to provide a Free SoftwareGUI environment for palmtop/handheld computers running the GNU/Linuxoperating system. GPE uses the X Window System, and the GTK+ widgettoolkit.
GtkFB -- beginning with version 2.0, GTK+ will support renderingdirectly to the Linux framebuffer instead of using the X Window System.This is good for embedded systems and devices with limited resources,because it eliminates the overhead of an X server, while still takingadvantage of the power of GTK+ and the large base of existing programs.
handhelds.org PDA support -- want to create your own unique Linux PDAimplementation? handhelds.org is for you! Early this year, Compaqcreated the Open Handheld Program, an initiative designed to stimulateinnovation and research on handheld devices that resulted from thecompany's "Itsy" pocket computer project. To support this initiative,Compaq created handhelds.org -- a vendor neutral website dedicated toopen source handheld development. Not surprisingly, Compaq's iPAQ PDAis used as the base platform for all these activities and,consequently, a iPAQ Linux port is available as freely available opensource software.
Matchbox -- a small foot-print window manager and associatedapplications, designed specifically for resource-constrainedX11-enabled devices such as handheld computers, PDA's, set-top boxes,and consumer devices where display size, storage, CPU bandwidth, andinput mechanisms are limited. Matchbox includes a window manager, apanel, a desktop, a shared utility library, and a number of small panelapplications.
Microwindows -- an Open Source project aimed at bringing the featuresof modern graphical windowing environments to smaller devices andplatforms. Microwindows applications can be built and tested on theLinux desktop, as well as cross-compiled for the target device.
NxZilla (formerly nanozilla) -- a set of libraries that allow Mozillato be used with a NanoX server from the Microwindows project.
OpenGL ES -- a light-weight, royalty-free embedded graphics standardthat provides graphics API profiles for a broad range of embeddedsystems and devices, including handheld wireless devices, automotiveand avionics displays, and multimedia consumer devices such as advanceddigital TVs, set-top boxes, and game consoles.
OpenGUI -- a fast, 32-bit, high-Level C/C++ graphics & windowinglibrary/GUI built upon a fast, low-level x86 asm graphics kernel. It isunder LGPL license. OpenGUI provides 2D drawing primitives and anevent-driven windowing API for easy application development.
PicoGUI -- small, portable client/server GUI designed to work on manytypes of hardware including handheld computers. Like the X WindowSystem, it has a flexible client-server architecture. Unlike X,however, fonts, bitmaps, widgets, and anything else the applicationneeds are built directly into the server. This sacrifices a smalldecrease in flexibility for an increase in speed and a large decreasein size.
Qt/Embedded -- provides a full graphics stack, from the hardwareinterface to a full GUI tookkit. Although the API is identical to thepopular Qt/X11 and Qt/Windows products, Qt/Embedded is not based on X11and therefore it has substantially reduced memory requirements. Memorydemands can be tuned to the range of 800 KB to 3 MB in ROM (Intel x86).Qt/Embedded is available as open source software, under the GNU GeneralPublic License (GPL), or can be licensed on other terms from itsoriginator, Trolltech.
Simple DirectMedia Layer -- an open source cross-platform multimediadevelopment API/library designed to provide fast access to the graphicsframebuffer and audio device. SDL is currently being applied to anumber of Embedded Linux implementations such as Microwindows.
Tiny-X -- a small footprint X Window server implementation for embeddedsystems. It was developed by Keith Packard of the XFree86 Core Team,sponsored by SuSE. The goal was to create something that would workwell in a small memory footprint and, importantly, be robust in nearout-of-memory situations. Typical X servers based on Tiny-X can fit inless than 1MB on x86 CPUs. The project has since forked into severalprojects, including KDrive, SmallX, and Integrated Tiny-X.
ViewML -- a freely available, open source web browser targetedspecifically at the embedded Linux platform. Currently, ViewML alongwith it's interface requires 2.1 MB of RAM, with a disk image of only760K.
WML Browser -- a project, sponsored by 5NINE to develop a browser whichwill allow any wireless device to have WAP functionality. It mustsupport multiple protocol stacks (WAP 1.2.1, http), in differingenvironments, using differing input devices. The browser will work withframebuffer graphics.
Xynth Windowing System -- a free software project to build a portable,embedded client-server windowing system. The Xynth Windowing System,released under the GPL, offers a lightweight GUI-capable windowingsystem usable in Linux-based embedded systems and devices, such ashandhelds and set-top boxes.
