摘　　要：笔者为解决学生因缺乏必要的测试工具而导致课外电子实验效率下降问题,研制了一款基于AVR单片机的简易示波表。本文分析了系统需求,确定基本参数,给出了直流电源模块、测量电压/波形的硬件设计主要电路和软件设计思路。实践检验表明,示波表各项功能完全达到预期目标。In order to solve the problem of low efficiency in extracurricular electronic experiments due to lacking of measuring tool, a simple scope meter based on the AVR microcontroller is developed. The system requirement is analyzed, the basic parameters are determined, and the design circuit of hardware and the design ideas of software for the DC power supply module and the measurement of voltage/waveform are presented. The functions of the scope meter achieve the expected goal by the tests.
