MultiWii

Use a more recent version of the compiler like GNU Tools ARM Embedded\4.8 2014q2 to avoid that linker problem.

Hi Warthox no problem. See my post: [url] m[/url] concerning the hard wiring. Besides ardupirate code MW Code 2.0 is running without any problems (including GPS) too. Of course you have to adapt the #defines in the sources. In my case allinoneboard and the correct i2c addr for the acc 0x82 and the s...

I would appreciate this.
A step towads unifying the GCS. I use qgroundcontol with the Mega Pirate (Arducopter) Code. GPS-Support and map-display.
And its open source working with linux too.

I would have offered a similar sketch. But as I see now the latest dev Version (5008) of the MultiWii Code (used by arnaldo) is displaying distinct x,y and z-mag values too. It proved my problem: In the (dev)MultiWii GUI the z-mag-value is fixed to "500". Mag-x and mag-y seem to be ok. I a...

Could you post some representive (raw) z-values, obtained directly from the hmc5883L registers 5 and 6. Correct z-values are essential for transforming the mag-values in the horizontal plane and tilt-compensation. If the z-values are not correct the heading reading is somehow erratic as described ab...

HMC 5883 L issue The issue with my HMC5883L is the lack of valid z-axis values. They are normally stored in the registers (0x05 and 0x06; HMC5843 uses register 0x07 and 0x08). Reading those registers combined always shows the values 0 or -4096. x-, and y- readings are ok. (Datasheet -4096 indicates ...
