Hello
Indeed the LCD does not have backlighting.
Quoteif it has only 14 pins, is not equipped with backlight.

Thanks Les, With the PIN R / W low the LCD works correctly.
QuoteThe compiler does not use the RW pin for an alphanumeric LCD, so the LCD_RWPin declare can be removed. That declare is for a graphic LCD.

Make sure the RW pin of the LCD is connected to Gnd.

The MICROCHIP documentation regarding the PICDEM 2 PLUS card is very confusing, in the diagram it indicates that the pins used are from port D while the card uses the pins from port A

Now I'm going to try to use the ST7735 library on this same board.
Thank you very much Foro for the great help provided
