可以计算CAN总线的PDU中的29位扩展帧ID，只要输入优先权P、PGN码和源地址SA，即可计算得到29位的ID.同时，也可以由PGN各个细分的组成部分来计算CAN ID。-The 29-bit extended frame ID in the PDU of the CAN bus can be calculated, and the 29-bit ID can be calculated by entering the priority P, the PGN code, and the source address SA, and can also be calculated by the components of each segment of the PGN CAN ID.
