Application for Designing Communication Algorithm Using CAN with CANaerospace Protocol

Anotace: This paper introduces the most common data buses used in on-board aircraft electronic systems focusing on affordable buses and the reason for their use. Controller Area Network (CAN) was selected as the main bus representative. CAN has its special use in avionic systems called CANaerospace. In avionic systems, it is necessary to access the bus at precisely defined time intervals according to the schedule called Cycle Matrix. There is a need to develop an avionic system application for designing Cycle Matrix. Therefore, this paper focuses on mathematical analysis and a detailed description of the user application for designing Cycle Matrix in MATLAB environment. The application is intended for CAN bus specialists and it is supposed to assist with the design of communication algorithm for any avionic system.
