An improved design of the embedded electronic measurement system

In this paper we integrate an embedded board with interface circuits in a design of an embedded electronic measurement system (EEMS) with a new human-machine touch panel interface. The EEMS includes general electronic measurement instruments such as a waveform generator, an oscilloscope and a power supply. We integrate three electronic measurement instrument interfaces into one window which works in cooperation with the touch panel. We also enhance the program by having the system fetch the touching position, so that it can do this continuously. We use and process the touching positions to improve aspects of the operation of the human-machine interface like the drawing and the shifting adjustment of the arbitrary waveform, so that the operation interface becomes more user-friendly. We also design a mean filter program which adds up and averages both the touch point and neighboring points, so that the arbitrary waveform can be outputted more smoothly.
