Bridge---Canyon-on-Hardware

Welcome to Bridge, the hardware adaptation of Canyon, a convolution reverb plugin. This project utilizes ELK Audio OS and the Raspberry Pi Compute Module 4, featuring three custom-designed boards (1 main board and 2 IO boards). We created this project as the foundation for a complete OpenSource Audio FX Pedal based on community's resources.

Overview

Bridge extends Canyon's convolution reverb into the physical realm, combining the power of ELK Audio OS/HifiBerry DAC+ADC and Raspberry Pi Compute Module 4 for a robust audio FX solution.

Features

• Convolution Reverb: Achieve realistic and immersive reverb effects through Canyon.
• Custom Hardware: Three boards - 1 main and 2 IO boards - designed for modularity and reusability.
• ELK Audio OS: Leverage the efficiency of ELK Audio OS for real-time audio processing.

Hardware

Bridge comprises the following custom-designed boards:

1. Main Board:

   • GPIO/HAT Connector
   • SPI Screen Connector for a 480*320 ILI9488 based screen
   • Raspberry Pi Compute Module 4
   • ATMega328p with ICSP connector for IO management

2. IO Boards (x2):

   • Pots and Switches for massive fun
   • Rotary encoder

Software

Bridge relies on serveral pieces of sotware to run :

1. ATMega328p:

• Potentiometer values conversion
• Screen management
• Serial communication with CM4

2. Compute Module 4:

• Running ELK Audio OS for real-time audio processing
• IO management
• OSC
• Serial Communication with ATMega328p
