摘要
PIC系列单片机,其硬件结构和指令系统采用了与众不同的设计手法。与51或者其他系列的单片机相比,PIC单片机的中断机制有其特殊之处,本文针对PIC16F87X系列单片机中断的特点,介绍它在频率计中的具体应用及使用中断时应该注意的几个问题。
PIC hardware structure and command system use a unique design approach. Compared with the 51 or any other series of SCM, PIC has its unique mechanism in interrupt. This paper aims at the interruptive characteristic of PIC16F87X, and introduces the SCM specific application in the ,：ymometer and the use of interrupt should pay attention to several issues.
