MakerPlane Engine Information System

Revision 1

The MakerPlane Engine Information System (EIS) is an advanced and very flexible aircraft engine monitoring system. It is part of the MakerPlane System of Systems architecture where disparate devices can be used together in a Plug and Play fasion.

The MakerPlane EIS is a combination of an Arduino Mega as well as a custom Arduino Sheild especially desgined to read aircraft engine data.

The Shield contains the necessary components for reading the inputs as well as the communications controllers and tranceivers to communicate via both CAN and RS-232.

This repository contains the official MakerPlane sketch that gives the MakerPlane EIS its functionality.

Status

Currently the code is not ready for flight but work is continuing.

The MakerPlane CAN-ArduinoLib and CANFIX-ArduinoLib libraries are required.
