Trabajo Preparatorio.

Realizar el diagrama de flujo, codificación y conexiones para resolver el siguiente

programa.

Mediante un teclado matricial de (2 × 2), realizar una conexión serial con otro

microcontrolador de tal manera que el segundo microcontrolador, muestre el

dato que contiene cada una de las teclas, al ser pulsadas.
