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.
|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. |
