Controller Area Network (CAN)-based data bus developing from microprocessor has presented its function capability for small aircraft
applications. Due to CAN access, microprocessor needs to cooperate with
CAN controller. While C8051F060 microcontroller has embedded CAN
controller, CAN avionics design becomes much simplified with better
reliability. This paper presents a prototype fabrication and verification for CAN avionics on electronic flight instrument system (EFIS) for small
aircrafts. The C8051F060 electronic board is designed as bus nodes to
connect to sensors and actuators for operation. With a full function
development and implementation, the test result verifies the performance
has improved with better reliability.
