刚才上传的频率计程序可能不太好，现在这个计数外部脉冲的程序，还是较好的，只是得自己从中截取出来(Just upload the program may not be a good frequency counter, and now this external pulse count procedures, or better, just get yourself out from the interception of)

1820显示温度（LED(595)）C语言版 通过串口设定温度和读取当前温度(1820 shows that the temperature (LED (595)) C language version through the serial port settings to read the current temperature and temperature)

125k t5557卡 读写(keil C51 T5557 READER)

与沉默的开关为iOS，精选ios编程学习源码，很好的参考资料。(And the silence of the switch is iOS, select learning IOS programming source code, a good reference.)

说明：  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.)
