本报告介绍了基于AT89S52单片机为核心的、以AD0809数模转换芯片采样、以1602液晶屏显示的具有电压测量功能的具有一定精度的数字电压表。在实现基础功能要求之上扩展了串口通讯、时钟功能、高压报警、短路测试、电阻测量、交流电压峰峰值和周期测试等功能，使系统达到了良好的设计效果和要求。( This report describes on AT89S52 microcontroller as the core, to AD0809 DAC chip sampling, digital voltmeter with a certain precision voltage measurement function has LCD display with 1602. On the basis of the functional requirements to achieve extended serial communication, clock function, high pressure alarm, short circuit testing, resistance measurement, AC voltage peak value and cycle testing and other functions, allowing the system to achieve a good performance and design requirements. )

STM32的GPS模块通过串口连接的实验，可以通过液晶显示GPS信息，包括精度、纬度、高度、速度、用于定位的卫星数、可见卫星数、UTC时间等信息。(STM32 GPS module via a serial connection test, you can display GPS information, including precision, latitude, altitude, speed, number of satellites for positioning, number of visible satellites, UTC time and other information through the LCD.)

最简单的读取AD值的程序。初始化时调用初始化程序，运行过程中，可以定时读取AD值。可以用做温度检测或者电压检测。(The simplest program to read AD values. Initialization call initialization program, running process, can read AD value at regular intervals. It can be used for temperature detection or voltage detection.)
