Oscilloscope with the Android Operating System

By Richard Paštěka


Bachelor thesis deals with the design of digital oscilloscope using the Arduino development kit. The theoretical part of the thesis discusses the basic parameters of digital oscilloscopes, sampling types and general characteristics of A/D converters. The thesis further focuses on the description of the development platform Arduino Mega ADK. The practical part describes the steps in the implementation of the oscilloscope. The general design transfers to a specific description of software and hardware solutions. The software consists of two mutually communicating programs. First, program of the microcontroller performs data acquisition. The second is used to render the measured waveforms on the computer screen. Hardware appropriately adjusts the measuring signal for measurement purposes befor Arduino Mega ADK platform. In the results the evaluation of the created oscilloscope waveforms and parameters is given tested by using a function generator
