PDA design and realization based on MiniGUI and embedded Linux

Based on embedded Linux OS and embedded graphic user interface MiniGUI, a multifunctional Personal Digital Assistant (PDA) using ARM9 MCU was designed. Firstly, MiniGUI and the application and development technology based on embedded Linux were introduced. Subsequently. The cross compiling environment for MiniGUI, configuring the compile option of MiniGUI, and explanting MiniGUI onto the developing board were introduced. Lastly, soft design and implementation of PDA and technical difficulties in the implementation were analyzed. This PDA prominented the characteristics of easy design, making good use of system resources. The test results show that this system is stable and has good scalability.
