See this design in the design of a large number of previous digital voltage meter, based on the use of microcontroller technology with A / D converter chip ADC0832 built a digital voltmeter. This article briefly describes the advantages and SCM systems; then introduces the digital voltage meter design process, as well as hardware and software system design. This article describes the AT89C51 microcontroller based on the design of the voltage measurement system introduced, 1602LCD function, ADC0832 conversion principle. The circuit design of novel, simple and convenient. The design can measure the voltage 0 ~ 5V, and displayed on the 1602LCD. This system consists of three modules: main module, display module, A / D converter module. Draw circuit diagram and work flowchart, and debugging, the final design of the system hardware. In software programming, using the C programming language . Developed a display module program, A / D conversion process.朗读显示对应的拉丁字符的拼音 字典 Keywords: AT89C51 microcontroller、1602LCD、 ADC0832. 目录 摘 要 III Abstract IV 1 绪论 1 1.1课题的来源 1 1.2课题的意义 1 1.3数字电压表的国内外发展现状 2 1.4课题研
