I have a problem with the LCD display . I use the official lcd with the peak in the box provided ( PIC18F45K22 ) . For code that I used in the examples given.
I wanted to know where is my mistake.
A hard configuration error
A programming error
Or the card is not working properly
Code: Select all

* Description:
This code demonstrates how to use LCD 4-bit library. LCD is first
initialized, then some text is written, then the text is moved.
* Test configuration:
MCU: PIC18F45K22
