Read the HMC5883L from sparkfun with Lego NXT

[B.C.]

Hi,

I want to read the HMC5883L with my lego NXT.

But i cant get it working.

In Arduino it works fine in the attachments you find the code for arduino and my attempent for a labview program.

I use 4.7K ohm pull-up ressistors.

Someone know how to get it working?

Not sure, but it looks like you are using the same address to read and write a register? Did you try using 0x3C as the first byte of the first command and 0x3D as the first byte of the second?

Yes, I tried but i still cant read anything on my labview programma.

I added shift registers for reading measeruments like in my arduino example. (attachements)

But as long i cant read anything they have no use.
