用mcs-52系列单片机实现等精度频率测量,T1引脚接被测TTL信号,晶振22.1184MHz,对任何频率都可以实现很高精度的测量(精度<1 ),结果从串口字符串输出,波特率115200,可以用串口调试器观察结果.-With mcs-52 family of single chip and other precision frequency measurement, T1 pin then measured TTL signal, Crystal 22.1184MHz, any frequency can be achieved very high accuracy of measurement (precision<1 ), the result string from the serial output , baud rate 115200, serial debugger can observe the results.
