# Arduino Communication protocol, Ensured (ACE)

The purpose of the Arduino Communication protocol, Ensured (ACE) is to provide reliable and reactive communication between a micro controller and a computer (or two micro controllers). The main features of the protocol are reliability, in a sense that the communicating parties know if a sent message was received or not, and reactivity, i.e. the main program loop is not blocked whilst waiting for a message response.

This project contains two reference implementations of ACE: the first, written in C is designed to be run on an Arduino; the second, written in Scala is designed to be run a computer. See the specification and the implementations for additional information.
