Abstract
Currently, the operating systems market has been shifting toward open, free, and community-established solutions widely adopted by computing and electronics specialists. A practical example is the Raspberry Pi single-board computer, which supports various versions of open and free operating systems. Applications in electronics find significant potential in the Raspberry Pi due to its ability to support full system development through its 40-pin general-purpose connector. In this project, an electronic system for the acquisition and generation of electrical signals was designed and implemented based on a Raspberry Pi microcomputer running Raspbian OS. This tool proved to be an appropriate and useful solution, given the wide range of instrumentation applications that require signal processing capabilities. The main contribution of this work is the development of a low-cost, optimized system for signal acquisition and generation, implemented using Python programming and a graphical visualization environment. It was applied in specific contexts such as electronics laboratories and telecommunications experimentation.
