Talk: 12:35–13:20 (English)

Raspberry Pi, Reflex and Haskell

In this practical talk, I show how I built a public display using Haskell, Nix, Reflex, a Raspberry Pi Zero W, an RGB matrix and a buzzer. I discuss the event driven architecture, how to build interfaces to C libraries, cross compiling with Nix, and some of the difficulties I encountered.
