So I did, it worked in 1.8p2, but then I tried 1.9 it didnt work, then I saw that use internal pullups was commented in 1.9 so I activated it, it worked !

After that I disconnected everything to try my quadcopter in my room. Connected the battery and the led Of the arduino stayed on.. So I went to my computer to check, and it gave I2C errors again, and a few minutes therefore it worked.. What the!? So I'm stuck with my dirst new quad, reading topics about the problem but no decent solution with photo's or something else, please could you show me how to use the pullups from what point to what point they have to be soldered? Or another working solution?

I spent over 300 euros for this quad so I really dont wan't to just let it go..

Please help, I asked this so much already on different forums! If you need photos ask!

First, nobody will help you if you SHOUT in red, its rude and not the way to get help.

OK Multiwii v1.9 doesnt like WMP and BMA020 and i have one quad that wont work on v1.9 for that reason. Go back to V1.8patch 2 its the best and most stable version especially if your using WMP and BMA020.
The debug numbers in the Gui are not errors they are what was left in when Alex was debuging it before it was released. This has been documented elswhere.
If your using a genuine WMP and BMA020 then internal pullups are fine, just dont use them if your using anything on 3.3v.
If you had everything working in 1.8patch2 then nothing can be wrong can it? so just go back to it and if you must use the latest version then wait for the next(non dev) version and try again and if you get any problems just go back to what last worked.
By the way 300 euro's is quite cheap for a good quad, but you aint gonna get an MK, you have to do some of the work, its NOT plug and play. If you dont want to get your hands dirty then you will pay a lot more e.g look at hoverfly boards and thats only the board, you still have to buy motors, esc's frame, RX etc,etc so 300 euro's is good value, but you have to read and learn a little to get it working right. to most of us that is half the fun.
