Pedal Pi V2 by Thawney is an all new and regularly maintained Pedal-Pi by electrosmash; a lo-fi programmable guitar pedal that works with the Raspberry Pi ZERO Board. My repository contains all of the information needed to create your own board from scratch unlike Pedal Pi who only share effect code.

Audio Effects Circuit Design & Embedded Systems (STM32F407 microcontroller) Design Project. Goal: with an analog audio input, pitch shift or add echo effect and output to a speaker. Circuit: designed AC level shifting circuit, active bandpass filter, LED matrix display and DAC quantization error smoothing in KiCad; manufactured as a printed circuit board; soldered components and tested PCB. Embedded Systems: FFT to extract frequency domain; NVIC with timer-raised interrupts to service analog sampling, button debouncing, and image display on LED matrix; memory and clock cycle optimizations
