【摘要】 MiniGUI是目前较成熟的嵌入式Linux系统的图形用户界面,具有小巧、可配置和可移植等特点。MiniGUI可以编译成两个截然不同的运行模式:MiniGUI-Threads模式适用于实时性高,功能相对简单的系统,比如工控仪器等;而MiniGUI-Lite模式多用于功能丰富,结构复杂的系统,如PDA等信息产品。文章介绍了如何在这两个运行模式下设计并实现多个串口的实时双工通信,最后还指出了两种模式下实现串口监听程序和同步问题方面的差别。更多还原

【Abstract】 MiniGUI is a better Graphics User Interface of embedded Linux system,which has lightweight,configurable and portable character.It can be compiled to two different running modes: MiniGUI-Threads mode is designed for simple systems which requires high real-time,like industry control apparatus,And MiniGUI-Lite mode is used in multifunctional and complex systems such as PDA.This paper introduces how to design and implement multi-serial full-duplex communication under the two modes.The difference of listening-program and synchronization problem between the two MiniGUI modes is pointed out in the end.更多还原
