lcdscreen 1.2.1

Installation

Install from pip

pip install lcdscreen

From there you can use it as you wish!

from lcdscreen import LCDScreen

Next, initialise the class, passing in the parameters as required:

lcd = LCDScreen({
        'pin_rs': 25,
        'pin_e': 24,
        'pins_db': [23, 17, 27, 22],
        'backlight': 18,
        'dimensions': [20, 4]
})

The defaults are below. If you don’t wish to change anything then you can initilise without passing anything in:

config_preset = {
        'pin_rs': 25, # The input of the RS pin
        'pin_e': 24, # The input of the E pin
        'pins_db': [23, 17, 27, 22], # The input of the DB pins
        'backlight': 18, # The input of the Backlight pin
        'dimensions': [20, 4], # How big your screen is [width, height]
        'delay': 3, # The default delay time
        'spacer': ' ' # The default spacer character
        'truncate': '..' # What to add to a truncated string if the message is longer than the screen width
}

Once initialised, it’s quite easy to operate. The class is well documented and the exmaple file shows how to use it
