Software Controlled Digital Oscilloscope

Project goal: To design, build and test a lightweight and portable oscilloscope in a price range suitable for both hobbyists and engineers. Oscilloscopes are essential for circuit analysis,but their bulk, expense and reliance on a power outlet often confine their use to the laboratory. The product designed, called the μScope, has two sub-assemblies: the simplified hardware and a graphical user interface to display its voltage readings. A printed circuit board was created to implement the input-phase circuitry for adjusting voltage readings to ranges readable by the analog-to-digital converter. All conversion was then performed via the firmware and sent to the microcontroller using serial peripheral interface protocols. Measurements are read by connecting the μScope to a computer via USB cable and signals are viewed in a graphical user interface, which was designed in LabVIEW because of its high compatibility with other system components.
