This example uses the LNP Addressing layer protocol. Run LNPAddrReadSensor on the PC. It works either with the lejos program LNPAddrSensorReader or the legOS program lnpaddrtest.c. To run lnpaddrtest.c you will need to install legOS and an H8300 cross-complier. See http://legOS.sourceforge.net You need to start the lejos or legOS program before running the PC program. The LNP Addressing protocol supprts point to point connections and communication between multiple RCXs.
