m4vga is a technique/library for hacking the STM32F407 to generate high-quality analog color video signals with just a handful of resistors.

• m4vga-rs is the current version, written in Rust.
• m4vgalib (and its demos) is the original version, in C++.

I wrote the C++ version between 2012 and 2015, and rewrote it in Rust in 2019 to put my money where my mouth is.

I did this because it was an immense technical challenge. Read on for details, including links to a series of blog posts I wrote examining the code in detail.

Here’s a collection of WebAssembly graphics demos and effects I’ve written. Most of these are trying to pack the most pizzazz into the smallest number of bytes.
