App note: Digital compass reference design

Posted on Saturday, June 9th, 2012 in app notes by DP

A PIC18F2520-based digital compass using magneto-resistive sensors to measure the magnetic field in 3-axies:

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.

  • KH: Really? They are digital inputs driven by an MCU. The MCU GPIO probably has diode clamps and ESD protection. Have you experienced such failures? Please...
  • KH: Neither. Google "Marco Schweighauser’s 8-bit virtual Javascript CPU" and see the first result. Sounds more like a very limited feature toy CPU.
  • Alan: "8-bit x86 like CPU" - isn't that an 8080, or Z80?
  • Geoff: Is it still Sunday somewhere? If so, yes please.
