UK Railway Dot Matrix

Dot matrix departure boards for UK railway stations, on the web and on a real LED panel.

Directory	What's in it
website	The raildotmatrix.davwheat.dev website: a Next.js site with every board, hosted on Cloudflare Pages.
led-board	The Daktronics Data Display and Infotec boards in Go. They drive a HUB75 LED panel on a Raspberry Pi, and the website runs them as WebAssembly.

Getting started

To work on the website, you need Node 24, pnpm, Go 1.21 or later, and Just, because the website's build compiles the LED boards:

cd website
pnpm install
pnpm dev

To build the LED board for a Raspberry Pi, you also need the vendored LED matrix library and Zig. See led-board/README.md:

git submodule update --init led-board/third_party/rpi-rgb-led-matrix
