摘要
为了达到简化电子设计中人机界面开发步骤的目的,运用一套包含按键驱动、液晶驱动、菜单维护和系统状态发送功能的单片机系统,通过通信总线与上位机通信将系统状态和发生的事件传送到上位机进行处理。同时接收上位机传来的系统变量显示更新、复位待机等控制指令并处理,使此系统完全承担复杂和耗时的按键及液晶驱动同时提供完备的应用程序功能。最后获得独立运行的系统,减少资源占用,提高系统的实时性能。
To simplify the development steps of man-machine interface in electronic design, the single-chip system with the functons of the key driving, LCD driving, menu maintenance and system state sending is designed. It is adopted to send the system state and the events to PC for processing through the communication bus and PC communication, and receive the control instructions of the system variable display update, reset standby and processing from PC at the same time. This sys-tem is fully responsible for the complex time-consuming buttons and LCD drive and provides a complete application functions. The independent system can reduce resource consumption and improve the real-time performance of the system.
