      • setPort

        public static void setPort​(I2CPort port)
        Set the sensor port
        Parameters:
        port - the sensor port the link is connected to

      • readPacket

        public static int readPacket​(byte[] aBuffer)
        Read an assembled packet. NRLink only seems to read one byte at a time reliably, and does not return zero bytes.
        Parameters:
        aBuffer - the buffer to return the packet into
        Returns:
        the number of bytes in the packet

      • isPacketAvailable

        public static boolean isPacketAvailable()
        Test if a packet is available
        Returns:
        true iff a packiet is available

      • sendPacket

        public static boolean sendPacket​(byte[] aBuffer,
                                 int aOffset,
                                 int aLen)
        Send a packet
        Parameters:
        aBuffer - the buffer containing the packet
        aOffset - the offset in the buffer - must be zero
        aLen - the length of the packet
        Returns:
        true iff the packet was successfully sent

      • setRangeLong

        public static void setRangeLong()
        Set long range

      • setRangeShort

        public static void setRangeShort()
        Set short range

      • resetSerial

        public static void resetSerial()
        Reset the link - null

      • waitTillSent

        public static void waitTillSent()
        Wait until the packet is sent - null

      • getLink

        public static RCXLink getLink()
        Get the RCXLink object associated with the Serial class
        Returns:
        the link
