该文件实现了用温度传感器件DS18B20对温度的采集，并在数码管上显示出来。(This file implements the using temperature sensor DS18B20 the temperature acquisition, and on the digital tube display.)

说明：  利用压电超声导波时间反转法的管道结构裂纹监测研究(Study on the Crack Monitoring of Pipeline Structures Using Piezoelectric Ultrasonic Guided Wave Time Reversal Method)

0.96寸OLED显示12864英文驱动，可显示2种字体(0.96-inch OLED display 12864 English driver, you can display two kinds of fonts)

说明：  官方AD7793参考程序，采用stm32f103(The official AD7793 reference program uses STM32F103)

基于单片机开发的无线识别装置系统中使用的应答器程序代码(The development of microcontroller-based system using wireless identification device transponder code)

说明：  使用STM32驱动AD9954 DDS模块(Driving the AD9954 DDS Module with STM32)

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.)

对51单片机的串口功能进行测试，可以提供初学者进行相应调试(For 51 singlechip serial function testing, can provide beginners corresponding debugging )
