摘要
介绍了一种可以提供多路输出可控周期和脉宽的脉冲时序电路,采用了PIC16f877单片机简化了复杂的电路结构,并给出了外围的硬件电路和单片机的程序设计。为满足设计要求,脉冲时序电路采用两种设定方式:本机所带的小键盘设置和上位机通过RS485通讯口对其进行设置。
This article introduces one circuit which can provide many tunes to output different kinds pulse.This design of circuit bases on microchip pic16f877,so it makes the design simply .This article also provides how to design the software and hardware.For supply the need of the system,we use two methods to set this circuit;the keyboard and the sign of PC.
