    摘  要:应用Proteus仿真平台实现虚拟示波器的设计,把波形发生器产生的波形信号作为信号源,通过A/D转换器对输入信号进行数据转换后输入到单片机,通过单片机数据处理后用虚拟串口把数据输出到计算机,最后由VC软件中的INGraph控件提取数据进行波形图的绘制。经仿真表明:该设计实现了虚拟示波器的功能,在实际应用中可以降低设计成本,缩短开发周期,提高效率。

    Abstract: This paper introduced the design of the virtual oscilloscope simulated by the Proteus based on MCU technique. After ADC digitization, the triangular wave or square wave signals by the waveform generator is extracted via related algorithm, and output to computer through the virtual serial port. Finally drawing of waveform based on the digital data by the INGraph controls in VC software was achieved. By using Proteus, the simulation of the virtual oscilloscope and design of MCU systems can be realized with less design costs, less development cycles and high efficiency.
    Key words: Proteus; ADC; oscilloscope; waveform generator
