Project Overview

The goal of the project is to provide a portable and electronic music processor based on the Raspberry Pi. Users can modify the actual effect of the processor according to their own hobbies and needs. You can click on the video link to watch it, if you like to welcome it. The main features of the project are based on the Raspberry Pi, real-time and portable. The project is completed in association with the University of Glasgow and is an exercise to gain experience with real-time embedded programming.

The core part of the project consists of three parts, input processing, effect realization, and output processing. In hardware, it mainly includes input circuit, output circuit, power circuit and Raspberry Pi. The core of the software part is the processing of digital signals.

The workflow is an electronic music device (guitar), which converts the analog signal into a digital signal by an input circuit, and then performs signal processing by the Raspberry Pi to achieve different effects. After processing, the digital signal is converted into an analog signal by the output circuit. Output.

Shijie Fang is mainly responsible for GUI and interactive design programming, and detecting hardware circuits. Wenjun Li is mainly responsible for the debugging of hardware circuit design and project integration. The entire project is assigned according to the different strengths of the members to achieve the desired functionality as much as possible.
