The Software Design Of The Dual Channels Digital Storage Oscilloscope Based On S3C2410

With the continuous development of digital technology,digital storage oscilloscope become an intelligent measurement instruments of measurement, display, calculation, recording and other functions.Digital storage oscilloscope is more expensive than analog oscilloscope in general,so it is less popular than analog oscilloscope.The purpose of this project is producting the high cost performance DSO with property rights and accumulatting experience and theoretical basis for the development of better performance DSO.First,this project describs the process of theμc/os-II embedded operating system transplant into ARMS3C2410 processor and divide the function of DSO into seven threads by analyzing theμc/os-Ⅱembedded operating system and the characteristics of ARMS3C2410 processor.Second, this project designs a scalable key module and menu with clear and rational structure, good portability and friendly interface.Third, this project designs an efficient algorithm of waveform display for solving the problem of low efficiency of the waveform display.Fourth, by analyzing the handled result by the cubic spline interpolation algorithm and sine fitting algorithm for different waveforms;design a algorithm for measuring the waveform cycle.
