PIC Introduction

The PIC is a small 8-bit microcontroller designed primarily for fast input/output control using a small instruction set. The PIC is low-cost (~$15), can be developed for free (free IDE, including simulator), and can be reprogrammed thousands of times (Flash EEPROM - no UV eraser required) from a cheap programmer (~US$10).

This introduction to using the PIC, with emphasis on the fourth-year design project, is as follows:

Datasheets

A collection of relevent datasheets and application notes is a must for designing any complex interaction between discrete components.

Infrared Beacon

The infrared robot beacon is a critical part of the RoboFlag project and is one of the most important aspect of the competition. This document outlines the design considerations involved with the PIC-based infrared robot beacon specification, and explains how you would design and build a beacon.

Each beacon consists of multiple emitters (an encoder chip and LEDs) and detectors (detectors and decoder chips) connected to a small microcontroller. The beacons work within line-of-sight, don't detect their own signal, don't interfere with most commercially available IR navigation sensors, and transmit up to four bits of data to other beacons.

This document is broken down into the following sections:

Visible Flag Beacon

The flag beacon is a critical component of the RoboFlag project and is one of the most important aspects of the competition. This document details the use of a flag beacon detector that is easily interfaced to a PIC microcontroller.

This document is broken down into the following sections:
