    摘  要:應用Proteus仿真平臺實現虛擬示波器的設計,把波形發生器產生的波形信號作為信號源,通過A/D轉換器對輸入信號進行數據轉換后輸入到單片機,通過單片機數據處理后用虛擬串口把數據輸出到計算機,最后由VC軟件中的INGraph控件提取數據進行波形圖的繪制。經仿真表明:該設計實現了虛擬示波器的功能,在實際應用中可以降低設計成本,縮短開發周期,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
