Hey KapteinKuk- any chance you'll release the source code for the firmware so we can all play around with it?

Thanks

If someone can send me one, I will pay shipping. Preferable close to Norway so the shipping will be low.

The KK2 must have died (no text, LED flash or beep), on its own. No crash or mis-wiring.

However, I can not supply a new board.
Bugger...

Do you think that it may come back to life if i flash it with your new firmware when you release it?

I have other FC i can use so its not the end of the world.

Its a shame it bricked itself as it had allot of potential.

Cheers

Just send it back to HK under warranty.
Maybe they will send it to Rolf or analyse and give you a new one.

Just Callibrated my esc's using the "y" splitter method, flawless, worked realy well. I have 4, 30A Blue series and trying to cal them using the fc is a nightmare, I believe it's because there is so much lag in the binding of spektrum receivers, the esc's enter into their program mode quicker than the Spektrum can react

I'm sure a good C compiler is not far behind assembler size wise, or speed wise.

Yes, If flash memory corruption is the problem, the new FW will fix it.

Do you have a programmer, and can check if the dead KK2 responds to it?

In deed, the code generation and the optimizer become better and better.

I think the advantage of your software is your "binary-float", that should be less code comsumptive than the standard float implementation.
If a software doesn't use floats, there may be an advantage for the C compiler over ASM meanwhile.

Hi,Simon,why dont you get "HK",to do a flashed speed controller,and get paid royalties,and then it will make us all happy,Marty.

Hi all,
I'm a bit confused about my KK2 board.
I have replaced my genuine DJI F450 frame with a home made 300mm quad frame.
I have calibrated the sensors and ESCs again as if starting afresh.
I have changed the following settings in my PI editor:

Roll/Pitch
PGain: 20
PLimit: 100
IGain: 0
I Limit: 20
Yaw:
PGain: 40
Plimit: 20
I Gain: 0
I Limit: 10
Self level is off,
Stick Scaling: Roll-30, Pitch-30, Yaw-30, Throttle-90.
It is still drifting to the left( I mean Motor #2 side) and I have put a set of new balanced props and a new quad frame.
What causes a quad to drift to one side only?Is it in the PI settings or other issues?Im lost.
It is a very easy board to learn and I have noticed it is quite stable during flight but only problem is drift.

Now onto receiver test:
I have noticed the following:
Elevator- stick movement forward, it shows (-94) a negative value on the KK2 screen!
Stick movement back, it shows +101+ a positive value on the screen.
Stick movement is correct though and corresponds to the appropriate movement.

Rudder- stick movement to the left, it shows +101, a positive figure on KK2 screen.
Stick movement to the right, it shows (-94), a negative figure on the screen.
Stick movement is correct.
Is this normal?
What am I missing?
Im using a Hitec- Aurora 9 Tx with Optima 9 Rx.
The rest, that is the Aileron and Throttle are fine and no dramas.
How do I fix this if it is wrong.
Anyone please care to explain where I'm wrong.
I really like this board a lot because of its ease to change settings on the spot.
Thanks a lot,
AeroR

You can start at around 80 and increase if it flips too slow for you, or if you like to be able to flip closer to center stick like me.

Best,
Chris
But I do!
I am also in this business for some time. This is how it flips@110 stick scaling with full stick (go to 0:45):

Yes, I agree with Neagron. It would be a win-win for all involved.
