Hi,
I’m going to become crazy with this sensor

I send a email to sparkfun about this problem , this is the replay;

Hello,I’m very sorry to hear about the trouble this sensor is giving you. The example code we’ve posted on the product page (http://www.sparkfun.com/commerce/product_info.php?products_id=9371) should work perfectly, and you can load it onto an Arduino with the need of an AVR programmer. This tutorial: http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=142, in the ‘Serial bootloading an Arduino board’ section describes how you can load the code using WinAVR.

There have been discussions of an incorrect capacitor on the board, but our tests show that the board does work with the current setup.

Hope that helps. Let me know if you have any further questions or concerns.

Hi Asilloo,

Still working on it. But we can’t figure out the date we get from the HMC, and how we have to put this in a picture of which way is north
Are you working on it too?

You probably don’t want that. The up to date code is in the Pygame repository or in Pygame 1.9 or newer.

Nevermind, found it here: http://git.n0r.org/?p=pygame-nrp.git;a=summary

The git repo seems have have gone; could you please put it up again or email me a copy of the code?

Hej,

Is there any one did this sensor work with Arduino, if the answer YES, please upload some videos on youtube so we can see what we have to do.
Regards,

I know this isn’t really a reply to this thread but I have been trying to get my HMC5348 working for quite some time without much success. The data sheet for the compass doesn’t go into much detail about how to read from registers other than from the data registers. So my question is, what is the proper way to read the status register from the compass? Would the correct sequence be:

start 0×3c 0×09 restart ‘receive enable’ 0×3d ‘read byte’ stop

start 0×3d 0×09 ‘receive enable’ ‘read byte’ stop

The data sheet is not clear about how to read from registers other than the data registers. Given the auto incrementing of the register address for this chip, I’m not sure if you can send an address after issuing a read command (0×3d).

Any help anyone can offer is greatly appreciated. Thanks in advance.

Does anyone knows what I have to do now? I used the HCM.zip files from above, but it still isn’t working..
