CONTADOR ASCENDENTE CON PIC16F84A
Introducción
En electrónica digital, un contador es un circuito secuencial construido a partir de un biestable y puertas
lógicas capaz de almacenar y contar los impulsos (a menudo relacionados con una señal de reloj), que
recibe en la entrada destinada a tal efecto, pero en nuestro caso todo eso lo hará el microcontrolador PIC,
a este PIC nosotros lo vamos a programar para que tenga un conteo ascendente.
Para saber a la configuración de los bits necesaria para mostrar cada número en el Display se sigue la
siguiente tabla.
Objetivo General
• Programar, configurar el PIC 16F84A para contar ascendentemente de 0 a 9 en el Display de 7
segmentos.
