Studying Digital Signal Processing on Arduino Based Platform

Digital Signal Processing (DSP) has become today an integral part of the basic skills required for scientists and engineers of many specialties. Most courses offer only using for DSP laboratory classes the Matlab system. This approach has the disadvantage – it excludes the students’ acquisition of the basic skills of software development for implementation of DSP algorithms based on real digital devices. DSP is informative technologies in real-time and in most cases they use the closest to the hardware Assembler and C/C++ languages. To eliminate this drawback the authors propose using for DSP laboratory classes the known Arduino platform. Nowadays, this platform is one of the most affordable budgetary and rather universal decisions produced on popular AVR microcontrollers. It allows using of the most popular in DSP Assembler and C++ languages. As an example the structure of the laboratory lesson: “Development and research of the moving average filter in Matlab and Arduino» is presented. This filter is the most common. Embodiments of the filter developed in Matlab and ArduinoUno-based controller are given. And oscillograms of the signals at the input of the filter and at its output are shown. Integrated using of the Matlab system and Arduino platform contributes to a better understanding of theoretical fundamentals of DSP, and more importantly, influence development of practical skills in design and development of microprocessor systems for DSP.
