Done with tedious mono color backlight? This Grove enables you to set the color to whatever you like via the simple and concise Grove interface. It takes I2C as communication method with your microcontroller. So number of pins required for data exchange and backlight control shrinks from ~10 to 2, relieving IOs for other challenging tasks. Besides, Grove - LCD RGB Backlight supports user-defined characters. Want to get a love heart or some other foreign characters? Just take advantage of this feature and design it!
This is an Arudino Library. It include a .h file, a .cpp file and some examples. Through these examples, you can quickly master the use of Grove - LCD RGB Backlight.
The folowing we will introduce some function which is used very normal.
At the very beginning of we use this lcd, we should had it initialized. You can use this function :
lcd.begin(16, 2);
It means that this lcd has 16 lines and 2 rows.
One of Grove - LCD RGB Backlight's most important feature is: you can change the color backlight, and it's a very simple thing, just use the folowing function:
void setRGB(int r, int g, int b);
You can clear the display by this function:
void clear();
void noDisplay(); // turn off display
void display(); // turn on display
void noBlink();
void blink();
void noCursor();
void cursor();
