4. XSbase270 XSbase270 is a embedded portable application development platform base on PXA270 processor

5. QT Qt is a cross-platform application development framework, widely used for the development of GUI(Graphical User Interface) programs.cross-platformGUI Qt uses standard C++ to build programs.C++ We used Qt3 to build GUI applications.

6. QT The GUI programs can rapid build by QT Designer tool. Fig. 1. The example of GUI
