This is a fork of https://github.com/the-raspberry-pi-guy/lcd, i only added lcdshow.py that implements some functions as blink and center.
The script takes the following parameters as input
-f message to display on first row
-s message to display on second row
-b blink first row
-B blink second row
-c center first row
-C center second row
-d duration in seconds
