Experimental Aircraft Avionics based on CanBUS

This repository is the public code and design store for the Kotuku Aerospace http://www.kotuku.aero contributed avionics project.

The goal of DIY-EFIS is to provide a reference implementation of an open-source avionics stack based on CanBUS.

There is a new branch called yehudi which includes the 2024 code base that is very different from this one. It is ALPHA code but includes the new moving map navigator code.

The key display technology is based on a Raspberry-PI and a 3D printed case and a power supply with a PIC processor implementing the CanFly protocol

The simplest way to try the code is to build on Microsoft Windows. This is not a supported platform for the actual device but will allow you to easily test the devices.

• If you don't have Microsoft Visual Studio 2017 download a free copy from www.visualstudio.com

• I use TortoiseGit to do the checkout of the DIY-EFIS repository.

• The shell used to test the applications is located at /tools/msh/msh.sln

• compile and run the code. You will get a prompt: muon> This indicates that the muon application is running. The muon library is the command line interface used to develop the code to build an instrument.

• at the command type the following:

  mkdir proton string layout "test" uint16 screen-x 320 uint16 screen-y 240 mkdir test exit exit mkdir krypton uint16 screen-x 320 uint16 screen-y 240 exit

• This will exit the shell. The code does not support run-time reconfiguration. Run it again and now 2 windows should open with one showing the startup logo. From this point the script for the layout and event handlers can be developed. Checkout the Facebook page for a screen cast of what happens next

We are working actively on ALPHA_1 which is now the default branch of the repository.

The repository branch RELEASE_2016 holds the complete designs as of 2016.

** Raspberry PI ** Portable C code that implements a full graphical display for avionics that can run on very low power devices. The development environment is Eclipse on Linux or Visual Studio on Windows

** Hardware Designs ** All diy-efis hardware devices are based on a common hardware family, the dsPIC33EP series from Microchip. These devices are programmed in C and have the core I/O functions needed by the CANFly systems. There is a common operating system and I/O drivers for most peripherals. These reference designs are located under the library called reference and can be used to base your own hardware designs on. All diy-efis hardware designs are open source and are provided in Eagle PCB format. They are designed to be very low cost 2 sided PCB's that can be hand assembled by a enthusiest. Kotuku Aerospace will sell boards, partial kits, full kits or assembled hardware based on these designs.

diy-efis is managed by Kotuku Aerospace and forms the basis of all hardware designs provided by them. The Kotuku designs are all 32bit embedded solutions and embed the latest code.
