Development of digital circuit virtual experiment equipment
------The control design of the Android mobile phone terminal display experiment
Abstract: Complete digital circuit virtual experiment equipment and need to have a set of standardized experimental system, including various simulation of digital circuit experiment instrument, simulation rules connection interface between instruments, experimental results show the control, overall this is a huge project, non human capabilities. Above, the single focus on experimental results display controls, oscilloscope controls, use of common nowadays Android phones, analog oscilloscope display controls work. However not to display waveform signal (that is, according to the process of pass over the data), display control to display the results can only be a straight line, can not determine the function is correct and effective, with Android phones connected real experiment circuit to obtain the electrical signal to be, but also the lack of corresponding hardware interface, so think of all mobile phones with the acoustic electric conversion function (which is an essential function, as is known to all, the call is convert sound into electrical signals to pass), namely the use of the microphone interface to collect sound information. Simulation of electrical signals, transmission to the oscilloscope display control sound of real-time waveform.
