**Note:** 

* Before installing MRAA on Ubuntu 18.04, please follow up the below instructions to insert the following drivers first and configure I2C devices:

    ```
     $ sudo modprobe i2c_i801
     $ sudo modprobe gpio-pca953x
     $ echo "pca9535 0x20" > /sys/bus/i2c/devices/i2c-13/new_device
     $ echo "sx1509q 0x3e" > /sys/bus/i2c/devices/i2c-1/new_device
    ```

* Not support SPI interface
