The Anti-interference Design of Single Chip Microcomputer Application System

Some viewpoints of application according to difference interferences with the single-chip microcomputer were declared, this paper illustrated a series of anti-interference techniques on hardware and software. In the aspect of hardware. The techniques included choosing microprocessor correctly, distributing printed-plank area reasonably, using program watch and follow timer, noise shield, etc. in software, there were such as establishing the trap of program needle, designing the watch and follow program for procedure, using the interruption handles unadapted, and so on. Owing to adopting above anti-interference techniques, the safety and reliability of measurement and control system based on single-chip microcomputer will be assured, which will improve the whole capability of system.
