Application for Communication Algorithm Design via CAN with CANaerospace Protocol

The paper deals with an introduction of the most commonly used data buses at aircraft on-board electronic systems with a focus on economically accessible buses. There is explained a reason of these buses usage. The main representative is selected here and that is Controller Area Network (CAN). CAN has its modification for avionic systems CANaerospace. For avionic systems, it is necessary to access to the bus at precisely defined time intervals according to certain schedule, which is called Cycle Matrix. It is necessary to devise the algorithm for given avionic system. Thus the core of the paper is mathematical analysis and detailed description of user application for Cycle Matrix design in the development environment MATLAB. The application is intended for users, which are knowledgeable in the problem of the bus CAN and it will allow communication algorithm design of any avionic system.
