Embedded GUI recently has been highlighted in the design of embedded products with the widespread use of embedded system for implementing the human-computer interaction function. A gene amplification system based on ARM embedded Linux OS is introduced. Combined with the requirement of PCR gene amplification system, this article using Samsung's S3C6410 core processor, the choice of Linux + Qt software scheme, built the hardware and software development environment and realized most functions of the gene amplification system GUI based on Qt integrated development environment, such as the real-time temperature curve display, the parameter settings of circulating process and other auxiliary functions showed on LCD. The results demonstrate that the system can reliably and stably run on the Linux system, support for touch screen driver interface for easy operation, excellent scalability, superior performance, beautiful interface, and basically meet the functional requirements of each module.

Research and development of embedded systems is the hot information technology and the graphical user interface (GUI) is the most important part of human-computer interaction interface. These embedded GUI system has been widely used because of its strong and powerful functionality. But many times , it is necessary to sacrifice performance for its versatility. In this paper, the embedded GUI systems based on the message mechanism is study considering the short of current embedded GUI systems. The novel method of a message-driven application framework is suggested to solve the problem of the current message mechanisms for the implementation. Meanwhile, a circular queue algorithm is given in order to achieve messaging unit. Then, the message has been classified considering of efficiency. In the end, the design example of personal assistant is given.

With the development of embedded system, the implementation of application based on Qt and embedded Linux is an emphasis in researching the embedded GUI system. This paper introduces the cross compiling process and Qt/Embedded, and then describes how to develop the applications on Qt/Embedded. The methods in this paper have been validated on this developing platform(QQ2440V3).

Against some problems which exist in the current embedded graphical user interface development such as low efficiency in the operating, poor portability and so on. This paper brings up an embedded GUI development method based on Qt/Embedded. Firstly, the construction technology of X11 virtual compiler platform and the implementation technology of cross-compile environment are described in details which are necessary in GUI development. Secondly, the Qt library file is cut, and the picture is displayed with Chinese-characters in accordance with the specific embedded goal. In the end, prove the valid of the development method based on Qt/Embedded through applications.
