摘要
介绍一种由单片机AT89C51构成的转速测试器的工作原理。该测速器是通过采集电磁式转速传感器发出的脉冲信号由单片机记数,数据经内部程序计算、分析、处理,它的实时转速值通过LED显示非常方便直观。
AT89C51 posed by the speed of monolithic microcomputer tester works. The gun is collected through the speed sensor electromagnetic pulse signal issued from the number of monolithic microcomputer entry, data calculated by the internal procedures, analysis, processing, real-time speed of the value the intuitive LED display is very convenient. through
