Work in progress digital effects module

Post image

Dear Community,

I am working on a digital effects module. ESP32-S3 based, 10hp wide.

Its going to be my first time doing DSP stuff and being completely honest: I am so lost when it comes to programming 😅 But I will manage...

I heard there is a great sound library for esp32

I did some coding in Faust for ESP-32 a few years ago. I found it to be underpowered compared to an FV-1 but maybe there's more CPU available in the newer version. https://github.com/HolyCityAudio/ESP32

I had fun with an ESP32 a few years ago. The biggest breakthrough then was using PlatformIO (on VS Code) rather than the Arduino IDE.

A few months ago I had a semi-failed attempt at a module. Claude Code did most of the work. Big mistake was not breadboarding before soldering up on stripboard. A couple of the analog inputs that should have worked, didn't (still a mystery - everything looked ok against the data sheets).

Will definitely check out your projects.

I also installed PlatformIO on VSCode :) I designed my own ESP32 board instead of using a Devkit so I have a bit of trouble uploading the code. The project expects 8MB of Flash memory but detects 16MB (which is correct).

I know it can be programmed because a friend of mine managed to do it. But I wanna be able to do it myself.
