RGB1602 of RaspberryPi with C++ and Python3
---------------------------------------------------------
## Enable I2C:
    Input: sudo raspi-config in terminal
    Select: Interfacing Options
    Select: I2C; enable I2C

## C++:
### install wiringPi(Please skip this step if you have already installed the library.)
    git clone git://git.drogon.net/wiringPi
    cd wiringPi
    ./build
    
### Use C++ example
    make AutomateRoll   # Compile and run the sample AutomateRoll.cpp
    make Button   # Compile and run the sample Button.cpp
    make clean   # Clear files generated by compilation

### API
#### Change Color of Backlight
One of Grove - LCD RGB Backlight's most important feature is changing the backlight color. It's very simple; just use the folowing function:

    void setRGB(int r, int g, int b);

#### Clear display

You can clear the display by this function:

    void clear();

#### Turn on and turn off display

    void noDisplay();     // turn off display
    void display();       // turn on display

#### Blink

    void stopBlink();
    void blink();

#### Cursor

    void noCursor();
    void cursor();

#### Blink LED Backlight

    void blinkLED();
    void noBlinkLED();


## Library of python3

### install smbus
    pip3 install smbus
    
### Use python example
    python3 AutomateRoll.py
    python3 Button.py
