| Abstract: | In this paper,the limitations of bit arbitration mode of CAN bus is analyzed.In order to overcome these limitations,we design and implement a communication experiment of CAN bus based on C8051F MCU.By changing the time-delay of nodes competing with each other on the bus,all the nodes can equally share the bus.Furthermore,it improves the stability and real-time performances of the system.The method can be widely applied into the real time communication applications in a variety of industrial control systems based on CAN bus. |
