Development of a Cost-Effective and Portable Digital Storage Oscilloscope Using Raspberry Pi Pico and Mobile App

This paper presents the development of a cost-effective and portable Digital Storage Oscilloscope (DSO) utilizing the Raspberry Pi Pico microcontroller in conjunction with the Scoppy Android application. The proposed system establishes a robust communication interface via USB OTG, facilitating efficient data transfer and real-time signal analysis. By integrating the Raspberry Pi Pico with the Scoppy platform, the system delivers a viable alternative to conventional DSOs, offering real-time waveform visualization and advanced measurement capabilities. The Scoppy application's user-friendly interface supports precise adjustments, including time-per-division and voltage scaling, ensuring an intuitive user experience. This work aims to lower the accessibility barrier to high-performance measurement tools, thereby fostering innovation and advancing experimentation in electronics design and development.
