【Abstract】 A method of design and realization of virtual oscilloscope is presented. As a slave computer,the single-chip microcomputer AT89C51 system collects voltage inputs. As a master computer,the microcomputer realizes display functions of virtual oscilloscope.The master computer communicates with the slave computer by RS-232 standard serial communication interface. The hardware circuits and the software block diagram of the system are also provided.更多还原
