Send an I2C command.

Send a command to an I2C device at the standard command register: I2C_REG_CMD. The I2C device uses the specified address.

Parameters

port	The port to which the I2C device is attached. See the Input port constants group. You may use a constant or a variable. Constants should be used where possible to avoid blocking access to I2C devices on other ports by code running on other threads.
i2caddr	The I2C device address.
cmd	The command to send to the I2C device.

Returns: A status code indicating whether the write completed successfully or not. See CommLSCheckStatusType for possible result values.
