HOLA disculpen podrian ayudarme porfavor esque tengo un problema con un microcontrolador pic16f877A y una pantalla lcd 16x2 lo que pasa es que no me quiere funcionar no me muestra los caracteres, solo pone una linea puros cuadritos y esque tambien le estoy poniendo una señal analogica al pic, esque quiero que la pantalla lcd me muetre la velocidad cuando el usuario mueva un potenciometro y esta es la señal analogica.

aqui esta mi codigo les agrdesco muchisimo su ayuda..

Hola FCR15, quizas si pones tu consulta en el subforo de assembler y con un titulo mas aclaratorio te puedan ayudar los colegas que trabajan dicho lenguaje. Yo no te puedo ayudar.

Saludos.

Primero que nada ya lo ira a mover algun administrador al foro de ASM, asi que no crees otro tema mas.

Ahora veamos un poquito del programa

Código: ASM

STATUS           EQU    0X03
        PORTD            EQU    0X08
        PORTB            EQU    0X06
        TRISD            EQU    0X88
        TRISB            EQU    0X86

Esto no es necesario, eso ya esta definido en el P16F877A.INC

Hay muchisimas cosas mas que no entiendo por que la estas haciendo asi. Por lo que veo no te alcanzo el foro para todo el codigo, antes de analizar este codigo y ver que esta causando exactametne ese problema, te sugiero que te crees un nuevo proyecto pero que solo escriba un caracter en el LCD, y ahi vamos a ir probando, por que este codigo tiene MUCHISIMAS cosas redundantes y algunas partes mal realizadas. Tanto que no se ni por donde empezar.

Por eso mismo te sugiero que solomamente crees un proyecto para que escriba o un caracter o una frase en el LCD (sin ADC). Para poder ver si es error de tiempos o los comandos del LCD, etc.
