摘要
讨论CAN总线如何陷入数据超载状态,在这种状态下当主控制器还没有足够的时间来得及从接收缓冲区内取出信息就产生数据超载信号,这意味着数据被丢失,并可能会导致系统冲突。在此介绍了一种避免和处理数据超载的有效方法。
We discussed how the CAN bus runs into data overrun status.In the case of this status,the host controller is extremely overloaded,as it does not have enough time to fetch received messages from the receiving buffer in time.A data overrun signal is generated.That means messages are lost and causing conflict in the system may be caused.A valid strategy was introduced to avoid and deal with this unexpected condition.
