Python library to control DFRobot Gravity I2C LCD1602 with RGB Backlight Display or similar.

This library is based on official library DFRobot_RGBLCD1602 to control DFRobot Gravity I2C LCD1602. The offical library uses deprecated wiringpi, but this uses smbus and it's released as a standalone library.

Feel free to use and enjoy your LCD.

1. Connect your LCD to RPi via I2C pinouts, it accepts 5V.

2. Enable I2C on your RPi (using raspi-config)

3. Install (apt-get install i2c-tools) and use i2cdetect to check addresses.

   Example:

    $ i2cdetect -y 1
   
        0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
    00:          -- -- -- -- -- -- -- -- -- -- -- -- -- 
    10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
    20: -- -- -- -- -- -- -- -- -- -- -- -- -- 2d -- -- 
    30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- 3e -- 
    40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
    50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
    60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
    70: -- -- -- -- -- -- -- --   
   

   (the module uses 2 addresses)

   Alternatively you can assume that the LCD has an address 0x3e and RGB's address depends on the hardware version: 0x2d (RGB V2.0), 0x60 (RGB V1.0), 0x6b (V1.1), 0x30 (V1.0).

pip install dfrgblcdpy

from dfrgblcdpy import DFRRGBLCDPY

# default addresses
lcd = DFRRGBLCDPY()

# set white backlight
lcd.set_color_white()

# first line
lcd.print_out("Hello!")

# second line
lcd.set_cursor(0, 1)
lcd.print_out("World!")
