DIY-EFIS is a project to develop an open-source EFIS for experimental aircraft. The system comprises source code written in C++.
The primary flight display has been migrated to using CANaerospace as the data feed for the system. This is currently being tested using a prototype AHRS and EDU for a lycoming engine.
The code is written to use a Lawicel CANUSB interface for the data feed and is working on Windows and Windows CE although only a target project for Windows is provided due to the licening issues around Windows CE.
We are working on a port to the Linux platform. is the commercial sponsor of the project
