Everything went great, now I have to see what must I do now, I'll only read once again, then see what happens.
Thanks so much

I am trying to implement the headfree mode with a HMC5883L mag but i am unsure how to connect to a fluyduino.
I made this drawing for what i intend to do, or do i have to use the logic level converter
Do i need to enable pullups in software
|Dec 15, 2011, 12:44 PM|
yes a llc would be beter, as there are Pullups on the WMP which will put 5V on the line even if you disable the pullups.
The 3.3V can be taken from the d37 too, as its only a failure in the print, pls look on the bottom, if there is 3.3V written under the d37 pad, its 3.3V.
You may can , DONT connect the pullup cable on the BMA, dissable the internal pullups and solder your own 3.3V pullups, between datalines and 3.3V pad, that should work, but care to dont get 5V voltage levels on the datalines!
Other way would be, use the llc which in on the BMA020!
Its allready there you just have to solder a wire directly on it.
There are some pics. on the net, some connected the 3205 from the clones directly to the BMA▀2▀ integrated LLC.
I would choose that way, sry i dont have a pic at my hand.

Quadrocopter Frame Set
Correct me if I'm wrong but you don't mention that your Quadrocopter Frame Set has the holes exactly on the CopterControl OpenPilot dimensions.
I really enjoyed building your frame, it fitted perfectly. I think you should mention that the frame can hold the CopterControl FC with just 4 standoffs fitted on the inner bolts.
Thank you for your nice frame.

I have a problem with my board. I can install the sketch, have used the same as jonnypaletta here: http://www.rcgroups.com/forums/showt...381577&page=80
If I then use the multiwii that shows nothing. I turn first to the comport then press Start, and then read, the curve is then gone. It was already described here.
My hardware is Flyduino Mega v2.1, Flydusensev1.2, BMA020 and original WMP. Has anyone an idea? In the BMA, I soldered all the contacts with the bob, is that a problem?
you cane watch my fotos above.

very nice and clean copter you have bulid. And a really good idea to use a loudspeaker enclosure as a canopy. My first thing tomorrow morning is to walk downstairs and discover my old hifi stuff - I'm pretty sure there will be a unused pair of those :-)

You choose the Atmega in the sketch instead of the Pro mini?

and THROTTLE is set to FAILSAVE_THR0TTLE value. You must set this value to descending about 1m/s or so for best results.
This value is depended from your configuration, AUW and some other params.
Next, afrer FAILSAVE_OFF_DELAY the copter is disarmed, and motors is stopped.

I use Multiwii1_7
I do not know where to solder the resistors, in series with Vcc and ground?
Thank you once you two.
At goofy32, voltage is OK, what's on it also depends, I choose on tools arduino mega 2560
Thank you again.
