单片机应用系统抗干扰设计

Design of Interference Rejection for the Single Chip Microcomputer Application System

叙述了单片机应用系统设计的注意事项，分别从单片机系统自检，单片机系统现场数据的掉电保护，单片机系统硬件抗干扰措施，以及单片机系统软件抗干扰措施等方面论述了单片机应用系统的设计．给出了一些实际应用电路和设计思想，对单片机应用系统的科研设计人员和单片机系统使用者有一定的参考价值。

Several points to be noticed in the design of a single chip microcomputer(SCM)application system are pressented.It consists four parts:the self-test of SCM system,the dataretention in no-electricity of SCM system,the interference rejectioin methods of SCM system’shardware,and the interference rejection methods of SCM system’s software. Several practicalcircuits are provided.
