writeRead

public boolean writeRead(int address,
                         boolean tenBitAddr,
                         byte[] writeData,

                  throws ConnectionLostException,
                         java.lang.InterruptedException

Description copied from interface: TwiMaster

Perform a single TWI transaction which includes optional transmission and optional reception of data to a single slave. This is a blocking operation that can take a few milliseconds to a few tens of milliseconds. To abort this operation, client can interrupt the blocked thread.

Specified by:

writeRead in interface TwiMaster

Parameters:

address - The slave address, either 7-bit or 10-bit. Note that in some TWI device documentation the documented addresses are actually 2x the address values used here, as they regard the trailing 0-bit as part of the address.

tenBitAddr - Whether this is a 10-bit addressing mode.

writeData - The request data.

writeSize - The number of bytes to write. Valid value are 0-255.

readData - The array where the response should be stored.

readSize - The expected number of response bytes. Valid value are 0-255.

Returns:

Whether operation succeeded.

Throws:

ConnectionLostException - Connection to the IOIO has been lost.

java.lang.InterruptedException - Calling thread has been interrupted.

writeReadAsync

public TwiMaster.Result writeReadAsync(int address,
                                       boolean tenBitAddr,
                                       byte[] writeData,
                                       int writeSize,
                                       byte[] readData,
                                       int readSize)
                                throws ConnectionLostException

Description copied from interface: TwiMaster

Asynchronous version of TwiMaster.writeRead(int, boolean, byte[], int, byte[], int). Returns immediately and provides a TwiMaster.Result object on which the client can wait for the result.

Specified by:

writeReadAsync in interface TwiMaster

Throws:

ConnectionLostException
