How to accept filtering on CAN bus

When the frame data of the CAN bus is transmitted on the bus, other CAN controllers determine whether the ID of the data frame on the bus is consistent with this node through acceptance filtering. If it is consistent with this node, then the data on the bus will be Stored in the corresponding register […]
