Abstract: This paper describes the design and the implementation of an embedded real-time operating system (RTOS): FDCX08, used for CAN and LIN bus, and introduces the design of a usual-controller based on this operating system. FDCX08 is used in CAN, LIN or CAN and LIN mixed bus. According to CAN and LIN bus’s character, it designs a mailbox system, which supports the communication of tasks among operating systems, to make FDCX08 as CAN node, LIN node, gateway note and so on. This system is real-time, lightweight, and simple-interface, which makes it suitable to be used in many fields, such as auto electron and industry control, where CAN and LIN bus are needed.
