Examples

YWROBOT LCM2004 IIC V2

import liquidcrystal_i2c

cols = 20
rows = 4

lcd = liquidcrystal_i2c.LiquidCrystal_I2C(0x27, 1, numlines=rows)

lcd.printline(0, 'LCM2004 IIC V2'.center(cols))
lcd.printline(1, 'and'.center(cols))
lcd.printline(2, 'python-')
lcd.printline(3, 'liquidcrystal_i2c'.rjust(cols))

Todo

Nice to have:

• A lot of methods from the original sources are still missing, as I do not need them. For a complete port these should be included
• Add docstring
