利用单片机实现RS485多机通信程序示例

功能描述： 利用AT89S51单片机的T0、T1的定时计数器功能，来完成对输入的信号进行 频率计数，计数的频率结果通过8位动态数码管显示出来。要求能够对2－40KHZ 的信号频率进行准确计数，计数误差不超过2/1-Functional Description: Using AT89S51 MCU T0, T1 timing counter function, to complete the input signal frequency counting, counting the frequency of 8 resulted in the adoption of dynamic digital tube display. Request to the 2-40KHZ signal frequency accurately count, counting error of less than 2/1
