Douhle CAN redundant communication have been realized among several hardware nodes based on μC／OS-II. The design mechanism, hardware and softy, are of double CAN communication were described in detail. The paper analyze the differences of CAN communication based on μC／OS-II and traditional foreground/background system.展开更多
