Acquisition Filtering

The acquisition service can filter out unwanted messages automatically. The mxfMIL1553RxAcqMsgSelectSet() function allows the selection of messages, based on message type/address/subaddress, that should be acquired.

Example

mil1553_aperiodic_frame.c

HMXF_BUFFER bmBuffer;
uint32 rc;

   ...

   // Deselects acquisition of RT4 SA2 TX
   if(!rc)
   {
   MXF_MSGID_MIL1553 msgid;
      msgid.type=MXF_MIL1553_MSGTYPE_TX;
      msgid.address=4;
      msgid.subAddress=2;
      msgid.reserved=0;
      rc = mxfMIL1553RxAcqMsgSelectSet(bmBuffer, MXF_MSG_DESELECT, 1, &msgid);
   }

   ...
