摘　　要：介绍一种基于单片机和点阵液晶的简易数字存储式示波器的设计方案。系统以MSP430F149低功耗单片机为控制核心;采用高速A/D芯片ADS830E采集信号,FIFO高速缓存IDT7204同步存储采样值;采样数据经单片机运算处理后,送点阵液晶12864进行显示。重点讨论数据处理和图形显示的软件设计。该系统具有可靠性高、采样频率高、成本低等优点。This paper introduces the design scheme of a simple digital storage oscilloscope, which is based on the single chip mi- crocomputer（SCM） and dot matrix LCD. MSP430F149 low-power SCM is used as the control core. Signal is sampled by AD830E high-speed A/D chip, and the sampling values are stored synchronously in IDT7204. After being calculated and processed by SCM, the processed sampling values are sent to the LCD 12864 for displaying. The software design of data processing and graphic displa-ying is discussed mainly. This system is of advantages such as high reliability, high sampling frequency and low cost.
