open

public boolean open(int typ,
                    int portNum,
                    RemotePort remotePort)

Overrides:

close

public void close()

Description copied from interface: IOPort

Close the port, the port can not be used after this call.

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface IOPort

Overrides:

close in class RemoteIOPort

i2cTransaction

public void i2cTransaction(int deviceAddress,
                           byte[] writeBuf,
                           int writeOffset,
                           int writeLen,
                           byte[] readBuf,
                           int readOffset,
                           int readLen)

Description copied from interface: I2CPort

High level i2c interface. Perform a complete i2c transaction and return the results. Writes the specified data to the device and then reads the requested bytes from it.

Specified by:

i2cTransaction in interface I2CPort

Parameters:

deviceAddress - The I2C device address.

writeBuf - The buffer containing data to be written to the device.

writeOffset - The offset of the data within the write buffer

writeLen - The number of bytes to write.

readBuf - The buffer to use for the transaction results

readOffset - Location to write the results to

readLen - The length of the read

setType

public boolean setType(int type)

Description copied from interface: BasicSensorPort

Set the operating type for the attached sensor. Normally type setting is only used with legacy sensors and for i2c devices (to set the speed and operating voltage). It is not normally used with EV3 sensors.

Specified by:

setType in interface BasicSensorPort

Overrides:

setType in class RemoteIOPort

Returns:

true if type accepted
