Answer for Carlos.

A ver Carlos, te escribo en castellano por que creo que me entenderas y mi ingles es peor que pesimo.

Ya antes de haber puesto esta consulta he mirado ese ejemplo y el otro que trae el pic c. El problema es que si le cambio el 877 por el 876 todo son problemas y como estoy empezando en c me cuesta.

Yo lo que quiero es usar el bus de 4 bits del lcd y usar el mismo puerto b para las se�ales de control para ahorras lineas del pic. Todo eso en el pic16f876.

Gracias

El problema no es el conexionado, es que cuando le dices a la libreria que usas el 16f876, la libreria que usa el pic c, no acepta este micro.

De todas formas puedes enviarme todo lo ue consideres oportuno a mi correo que es [email protected]

Gracias.

O problema que pode existir es la utilizacion de lo PORT_D.
Tienes de alterar lo LCD.C na linea:
Code:

// Un-comment the following define to use port B
#define use_portb_lcd TRUE

Eu tenho a funcionar desta forma
