ADC

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.)

iOS 网络状态监测。网络实时检测，用到Reachability（自行下载）,需加框架:SystemConfiguration.framework ios程序需要用到网络检测，有些程序是刚启动时检测一次，而有些则从头到尾检测网络状态。(IOS network status monitoring.Real-time detection and Reachability (download), frame: SystemConfiguration.framework IOS programs need to use network detection, some detection once when the program is launched, while others detect the network status start to finish.)

通过DS18B20读取温度（范围-55C~125C，精确到小数点后一位），通过4位数码管显示出来。 当温度为正且百位为零时，不显示，当温度为负时百位显负号。当温度百位和十位都为0时0都不显示。(Read through the DS18B20 temperature (range-55C ~ 125C, accurate to one decimal), through four digital tube display. When the temperature is zero and 100, do not show, when the temperature is significantly negative at minus 100. When the temperature is 100 and 10 are not displayed 0:00.)
