Graphical User Interface Research And Development Of Embedded System

Research and development of embedded system is one of the hotspots of information technology research at present.Such as the national strong support of the intelligent hardware,networking,smart home,robotics,physical computing and other areas need to support embedded systems.Today,the rapid development of technology,the diversification of user needs,embedded devices in the pursuit of powerful and rich at the same time,also continue to improve the user experience.Graphical User Interface(GUI)is almost a standard part of the embedded software system,and the GUI is now a part of the graphical user interface(GUI).The graphical user interface(GUI)is a standard part of the embedded software system.One of the important technical areas.This paper describes the design and implementation of GUI and the typical application in smart home equipment.The smart home equipmentTMS320DM365 hardware is the core of the master,the software uses the embedded Linux operating system.This paper introduces the background of the GUI and the current situation at home and abroad,and then a detailed analysis of this set of GUI system?It mainly includes:(1)the framework of the design of GUI systems,in the framework of the design Bingzhe hierarchical hierarchical,modular,structured design concepts,the system layered?(2)To achieve message processing,multi-threaded way to deal with the message,and the design of message hook processing mechanism,the message can be pretreated.(3)Design and implement the system to change skin quichly by f unct i on that the theme of rapid customization switching support,to achieve differentiated customization in the customer can quickly delivery,reduce customer demand for R&D human input.(4)To achieve the page,the control to create code automatically generated to support from the UI renderings directly after the other tool converted to code,the software developers from the UI renderings to the code to achieve the process of liberation,focusing on business functions aspects of development(5)To achieve the system to support automatic control of the page layout features,some of the more regular page programming,developers do not need to consider the control position,size,and technical details of the weak.With automatic layout,the system will intelligently calculate the area and size for the control.(6)Finally,through the introduction of this set of GUI system in the field of smart home appliances embedded application examples to reflect the application of the GUI system is simple and can properly meet product development needs.
