    R/W pin should not be left floating. Tie it to ground (1 = Read, 0 = Write) - the library just writes commands to the LCD module

    Welcome znanev. It would be nice if you take pictures while you set it up and put it here. The forum has a blog feature too, so you can start your own.

    Here's a very basic HD44780 driver for Stellaris Launchpad.
     
    Supports up to 20x4 LCD and a full PORTB register is used. Due to the nature of the GPIOPinWrite function which uses masking and whatnots, extra code on the driver will be written in the future to accomodate such functions.
     
    Uses two files: hd44780_lp.c and hd44780_lp.h
     
    An example is in the attachment. It's called "lab2" because I fooled around with the Stellaris Launchpad Workbook earlier.
     
    Note: Please refer to online tutorials on the HD44780 connections.
     
    Comments are greatly appreciated!
