The Actor Model applied to the Raspberry Pi and the Embedded Domain
summary
Claims that the Actor Model (Erlang/OTP) can orchestrate embedded hardware on a Raspberry Pi by: using Erlang/OTP for supervision trees and hot code loading, controlling GPIO through gpio sysfs (no C required for basic ops), and isolating access via a proxy to prevent unsafe rapid switching. Demonstrations show a working LED demo with concurrent blink actors, a software hardware simulator, and a prototype ponte bridge board; packages for Pi are available.
