Simple electronic compass

[Gerrit]

Hello all,

I'm looking for a simple design of een electronic compass.

I need aproxamatly 15° resolution

Does any one have a schematic and a simple piece of source code?


Reagrds,

Gerrit

Gerrit,
Try this electronic compass. Easy to interface to the PIC.

I have a design I did some time ago, based on the '1655' analogue compass sensor (this has a tiny magnetic compass needle, used as a 'magnetic amplifier', to give a much larger signal change, than is seen from 'fluxgate' compasses), using a 16C71, to drive a digital pot, giving 0-99, round the circle. The circuit was designed to allow this to directly drive the Lego 'mindstorms' robotic system. The code is in CCS C. The circuit is fairly simple (but does contain all the extra 'interface' hardware, to connect the unit to the mindstorms system. I use the watchdog, to allow the chip to sleep for a large amount of the time, switching off the compass itself at the same time, to minimise power consumption.
I could send you the circuits, and the code 'direct', if you give me an email address.

Best Wishes

Hello Hamlett,

I would be very interested in a simple design.
And sample (source) code in CCS C.

My e-mail address is gerrit@rc-engineering.nl.

Thank you al ready for your help.

Regards,

Gerrit Faas

Dear R. J.

I am very interested in your 1655 design (curently using Honeywell's HMR3300 and Vector 2X), please give me a kick to start it again,

My e-mail: mechwu@saturn.yzu.edu.tw

Thanks a lot,

Chang-Huei Wu

Hello Hamlett,

I would also like to have your design and the source code. Could you please email them to me at kamarul@um.edu.my.

Thank you in advance.

OK. Have forwarded the design to you.

Ok. On it's way to you as well.

I notice Mr Chang-Huei Wu, has sent me a 'private' post. These never seem to work (have a look back for comments about this 'feature' of the board...). He should have my direct email now, so if you want to talk privately, 'drop me a mail'. :-)
