Method Detail

setPort

public static void setPort(SensorPort 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
