Design and simulation of simple sillometer based on PIC16F877

介绍了一种基于低功耗芯片PIC16F877的简易测速计的设计过程,并给出了其在Proteus软件下的仿真结果。整个测速计的设计有效地利用了PIC单片机的CPP1捕捉功能,因而简单易行、成本低、可靠性强,而采用Proteus软件进行仿真,则缩短了测速计的设计周期,降低了开发成本。

A design and implementation process of a simple sillometer based on the low-power chip PIC16F877 is introduced, and the simulation results in Proteus are given. In the whole design, the CPP1 capture function of the PIC singlechip is effectively used, thus the sillometer is simple and easily, low-cost and reliable. Using the Proteus to simulate can shorten the design cycle and reduce the development costs.
