About the RTEP Pedal PCB
RTEP Pedal is an open source PCB design by Can-Bot, published on GitHub under the MIT license. It is a 2-layer board measuring 150 × 75 mm, with 30 components from 17 distinct parts.
Other key parts include the 24LC256 and MCP23017_SP. By type, the board carries 12 resistors, 8 connectors, 4 capacitors, 3 switches, 2 ICs and 1 jumper.
It belongs with the audio and dev boards & breakouts designs in this gallery.
From the project
Repository for ENG5220: Real-Time Embedded Programming - S.H.R.E.D Pedal
The Real-Time Harmoniser is a standalone real-time embedded system designed to apply audio effects (like pitch-shifting and gain distortion) to incoming audio with minimal latency. The pedal is controllable via a hardware interface and written for the ENG5220: Real-Time Embedded Programming course.
Key Features: - Modular DSP architecture with hot-swappable effect chains - Sample-by-sample processing for minimal latency - Real-time capable Harmonizer using SignalsmithStretch - Multithreaded control-safe design with atomic buffer swapping - CI-integrated Google Test unit testing - Memory-safe…
