摘　　要：利用单片机进行嵌入式系统开发时,经常会面临同时处理多个任务的要求。为了在资源紧缺的单片机系统中获得资源与性能平衡的条件下,实现多任务处理机制,提出了一种基于事件驱动的单片机多任务程序设计方法。该方法内核设计简单、代码少、移植性好,可用于大多数带有定时中断的单片机系统,使一些复杂的单片机程序设计简单化,逻辑控制具有实时性。Developing embedded system using single-chip microprocessor,we are often faced with dealing with multiduties at the same time.In order to implement multi-duties in sing-chip system of fewer resource,a new method of program design based on event driving is put forward.This method is simple,which can be applied for most single-chip application system with timer interruption,making some complex programming simple,logical control with real-time.
