I just bought the HM55B compass module and wonder if anyone has used it with a PIC? The module is a Parallax (#29123) product using a Hitachi HM55B compass chip. I downloaded some information one of which is code for use with an SX28 device which I am not familiar with.
Purchased from
www.HobbyEngineering.com, $29.95 and there are links you can follow to get information - none came with the module.
Can anyone shed light on using this module with a PIC - any and all information and/or code is appreciated.
**broken link removed** includes information on how the module works plus a flow chart which I hope to use to develop a PIC program.
Bad Link. Try:

Also try:

I think the resolution is 1.4 degrees.
Many thanks
