Heavy compiler (hvcc) sources running on ESP32-DevKitC powered eurorack module

This repo demonstrates a single file solution for running hvcc sources on the ESP32-devkitc, inspired by the Faust ESP32 architecture example. The hvcc compiler leverages the use of (a subset of) puredata operators on the cheap and fast esp32 uprocessor. The ESP32-devkitc combined with one PCM5102 CODEC, one WM8731 CODEC and an 8 port MCP3208 ADC provides a complete and available audio development platform with a very reasonable pricetag. UI provided via 4 buttons, 4 potentiometers and 4 leds.

Esp32-hvcc: common questions

What microcontroller does the Esp32-hvcc use?

The Esp32-hvcc is built around the ESP32-DEVKITC-32D, from the ESP32 family.

How big is the Esp32-hvcc PCB?

The Esp32-hvcc measures 150.5 × 127 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32-hvcc?

74 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32-hvcc design files?

From the sinneb/esp32-hvcc repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Esp32-hvcc design in my own project?

The repository has no license, so all rights stay with sinneb. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Esp32-hvcc without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
