Section 1. Introduction and Setup
1.1 Introduction
Motorola’s ASB520, MC68HC908QT2 Infrared Remote Control Reference PC
Board and software are designed to demonstrate how a simple, limited
function, dedicated remote control system could be designed. The objective is
to keep the design simple so a user can pick portions of interest to his design
and turn them into an application specific system. This system is specifically
programmed to control an APEX model 1201 DVD player.
A few of the more noteworthy features of the reference PC board are listed as
follows:
•
8-pin MC68HC908QT2 microcontroller
•
Infrared LED and driver
•
Visible LED to show activity
•
Six user push buttons
•
MON08 programming interface for in-circuit FLASH programming
•
Battery holder for 3-AA cells
•
Microcontroller current monitor jumper block
