Designing a Digital Compass Using the PIC18F2520

From Microchip Technology, Inc.
 

 
Digital compasses have become popular in the past few years due to the advancement of magnetic sensors and feature-rich microcontrollers. Compass applications have increased from simple, hand-held navigation devices to automobile navigation systems with voice recognition and up-to-date global maps. This application note will focus on a simple, low-cost, hand-held digital compass design using a Microchip PIC18F2520 microcontroller. This compass application can be integrated into your own design, or as a building block in an advanced navigation tracking device similar to one you would find in a sporting goods store or automobile. Before we get into the specific design of the digital compass, let's talk about compassing fundamentals. The information available on this topic is seemingly endless. Perform a search on the World Wide Web and you will find an abundance of information. In this section, we will cover enough of the basics of compassing needed to develop a digital compass.
