can anyone pls help me in doing lcd interfacing with pic16f877a

[preethin]

And the task is to display the string in lcd after it should increment to the next cursor continously once it displayed the entire string

     This code demonstrates how to use LCD 4-bit library. LCD is first
     initialized, then some text is written, then the text is moved.
