Nope

Haha boo!

If you run short on space, dump the code at me, I will help you pack it. GCC 4.7.1 and newer also have 24-bit types. Keep everything in one file as much as possible (or static inlines only in include files), make all functions static, -Os, and inline asm the interrupts with reserved registers. Check out this for the interrupt/register allocation stuff: https://github.com/sim-/kk/blob/master/kk.c If you look at the assembly, you'll see that GCC still does some pretty dumb stuff (like random assignments to registers that never get used for no reason that never gets used), but it's getting better.

@Eastcoast78 thanks for the feedback for AL trims... i was looking for that as i have the same problem (drift forward) and was afraid to touch these values as i went up to +10 without seeing any change... i will try more as you said that up to 30 still had problem...

*This was the only reason i flashed to V1.2 from V1.0.. Other than that i didn't notice any change in flight...

Back on topic - got my first KK2 and just figured out how to load the driver for the USB programmer (Sparkfun) to make sure the KK2 is up to 1.2 (was there a way to tell the firmware version from the screen/buttons?) Next, I hope to get this mounted up and see how it does. LOVE the LCD interface.
Thanks, i start to believe that my storage method did the job!... Although i had most of the time in storage (3.85/cell), i read somewhere that batteries should stay NO MORE than 24Hrs at full charged state!! Otherwise they start to build internal resistance... Are really SO sensitive?.. Anyway i can keep them for my twinstar as they last, order new Zippy for my quad and keep STRICTLY the rule of storage to see what happens!!!!

For the KK, same for me.. the time i was on V1.0, there was no info anywhere to see the version... after updating to 1.2 it shows for 2 seconds at startup...

next time out im going to continue adjusting them. until i see results...i guess

Heres a flight from this evening...worst thing about park flying is people coming up and asking you questions...i don't mind sometimes. Most of the time people don't even noticed me there as its kinda tucked out of the way. But doing a few flips sure gets there attention lol love the sound of the props biting the air.

Sometime though the questions are silly...like the lady asked me if this was a rocket ship today lmfao!! you can see them walking there dog around the 3min mark lol

Hi, can someone please tell me how I can get the Lazyzero sofware to work as I have been trying to flash my two KK2 boards ,I have the latest Java on my P.C but although I dowloaded the Lazyzero file it won't open ? I plugged in my Crius usbasp flashtool with board attached but although the Green light is on <on the Crius> nothing is happening? sorry to be so dumb but this losing me the will to live

Cheers MIKE.

Did you launch it from the serial bat file?

In worst case it will have to be multicopter type specific hex files, like on the KK1.

I'm going to use AVR-GCC.

After writing a few arduino (C) programs, I went back to assembly to fix my brushed motor ESC firmware.

Then it hit me: "What the truck am I doing? I have to be bat-shlt-crazy to write large programs in assembly! This thing is so cryptic that I have to reverse-engineer my own source code!"

Haha
This is a shocking news

After you play with arduino, that is a sick C ... you decided to stop playing in assembler, with the only issue is on some math lib that you can fix in no-time ... if you dont like to fix, make this lib in C, compile, and copy the assembler result ...

Debug in C is even more complicated, since the debugger is still using assembler ...


Strange decision
