| Abstract: | A low frequency virtual oscilloscope is introduced,which can be realized by TLC2543 and Visual Basic.The data are sampled by TLC2543 and sent to the personal computer through line print terminal(LPT),then the analog signal is changed into the graph that can be observed through the oscilloscope operation panel,which is designed by Visual Basic,in order to realize the similar function as an analog oscilloscope,such as sampling and showing the data with real time,!regulating the amplitude and the frequency,and moving the waveform horizontally and vertically and so on. |
