Introduction

The aim of this project is to combine two ESP32 SOCs to create a platform for rendering 2D and 3D graphics.

One ESP32 serves as a graphics host: it takes care of rendering and composite video out. The other ESP32 serves as the graphics client: it sends data and tells the host how to render it.

This project is inspired by Bitluni's composite video article and uses his code as the foundation for the 3D graphics host.

Hardware

The host should run on a standard (dual core) ESP32.

The client can in theory be any ESP32 with an available hardware UART.
