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.
