Hi Zhang, > Hello all : > i see some files in chips/rf230 , i see some words like TimeSyncPacket , > so i think maybe the time synchronization is implementated in rf230 , am i > right ?
Yes. The PacketTimeStamp interface is used to access the transmit or receive time of the packet. If you want to embed a time stamp inside the packet then you need to use the TimeSyncAMSend and TimeSyncPacket interfaces of the SimSyncSend component. > if yes , i want to know which arithmetic does it use ? What do you mean? The time resolution is currently 1 millisecond (continnuous) and 1 microsecond (stops of the mote stops). > maybe there are a corresponding paper , can someone give me a reference ? Not yet. a TEP is coming out soon. You should have no problem using the components I pointed out. The interface files have the necessary documentations.
