MultiWii

Hi, in beetween a next few days will be possible to use fully implemented GPS_FROM_OSD function in MultiWii code. So in this case GPS receiver will be (as usually) connected to OSD and needed GPS data for navi functions will be properly send and compute by FC to achieve RTH or PH. Stay tuned! Now th...

Hi Roman, thx for advice.....yes, I thought about this model of HK SS. I find some info that one of my collegue reflashed this ESC with 17a410_ppm_r06 from home.versanet.de and probably works fine.... I also think about Ziss's firmware....and need an info about possibility to use one Ziss fimware ve...

Hi Ziss, could you tell which FastPWM firmware fits HK SS 15(18) - simply one (with all black cables - non programmable one)
I heard that ESC has a 16MHz crystal and many modified firmware doesn't work fine with above ESC...and if you have a good one compiled .hex .... it will be great

Maybe you should try to use new procedure to connect NK...as a standalone sensor (not pigtailed thru WMP) and with #define NUINCHUCK in the sketch...but now I have one question...Did you tried a 100kHz I2C bus speed? Because original Wii sensors works only on 100kHz...

I never owned the original NK so I can't too much help by looking at the photo ... you should take a multimeter and check where is GND and Vcc ...

I think, maybe you have a wrong wiring of NK...In many NKs pinouts are:
1 Vcc
2 not connected
3 SCL
4 SDA
5 GND

(or maybe reversed, try to find GND in addition to whole board) - it should be in this case :1GND, 2SDA, 3SCL, 4 n/c, 5Vcc

...

This procedure is a "little bit" incorrect if you intend to use with MultiWii because in the sketch is declared min and maxthrottle values​​, and also mincommand. In according to them, communication between the FC and the ESC works. In addition, effects on behavior have the parameters like...

Maybe Alex or ziss_dm remarks, replies to this problem...I'm not the coder or degree in electronics...
ITG3200 refered to its datasheet - works on 3,3v.....
I use the 1prebis7 with added patches made by ziss_dm..Tommorow I can attach here my working sketch, today I write on another computer...

It is imposible to good work because ITG3200 needs 3,3v not 5v!!! Look to the datasheet of ITG3200....maybe ITG3205 can handle 5v, but IMHO it is impossible..
Look to thread about ITG3205, I posted today my solution, it is proven to work, but I have another WMP clone with ITG3205, the same as ziss_dm

So, guys...I made this fantastic mod by ziss_dm - direct connection of ITG3205 from WMP (as on my picture above, I2C lines to pullups on WMP, 3,3V from WMP regulator to supply NK) REMEMBER TO DISABLE ARDUINO INTERNAL PULLUPS in the code! - independed connection to I2C bus with Nunchuck, powered from...

Beautiful! Do you have any plans to make the Failsafe system more robust? I'm thinking calculating rate of descent using the z axis of the acc and initiating the disarm procedure after a certain amount of time where the gyros are still (which would mean the craft is still). How tricky is this? WAAA...

I have a similar problem of oversensitive WMP (ITG3205 onboard) connected "classic" as WMP. Could this be related to the bug which have described here? My problem is the improper reading of negative pitch and roll at a very rapid turnover gyro, about 0.5 sec to 90 degrees. I have described...

After a further, detailed studies in which the WMP is included ITG3205 (oversensitive), it turned out that the Alex's amendment related to the divisor parameters (I give / 4 and is very good) does not resolve by the end of a new problem. This is yet another bug in the WMP, you see - the rapid turnov...

OK, I get your point....I always think about gyro as a "WMP gyro" ...but in this case, this is only "WMP shield for ITG3205 gyro " And this is only standalone sensor on piece of paper with epoxy The same about Nunchuck. Now I'm clear. But it will be something wrong to attach &quo...

ziss_dm - what does mean "currently it is not possible properly reset i2c devices, code implemented only for WMP" ? Is your modified code (for WMP with ITG3205 and also overlow bug issue AND new code for NK) doesn't support D12 pin fast reset in case of frozen I2C bus? It is better to have...

hello, ziss_dm!
Please take a look on picture (i love M$ Paint )
Do I truly understand your idea of connections? Can I connect these 3 things directly with only wires , without any other elements (of course disabling internal pull-ups of arduino)? thanks

Great, Alex!!! THX for support OSD in MWC code

OK, the way of powering Wii sensor is clear for me...but what about Logic level on I2C bus (SCK and SDA lines), without LLC? Can Wii senors (especially your method of WMP conection, directly to ITG3205) handle logic level from Ardu?

I think, this is the best way to use Alex's native, legacy idea - use cheap WMP+NK. BIG THING, thank you a lot!
One question - with this mod (and WMP direct I2C from ITG3205 mod) can I supply NK the "oldiest way" from Vcc pin on WMP ? Or only new way with 2,8v taken from WMP (3rd kynar?)

It's incredible easy way to do this revolutionary mods !!!!! Thanks a lot! No more "crazy WMPs" with this mod!, and also for NK, these, for clear - more complicated (because a lot of new code) modifications, if will work, it will be most wanted, important and needed by everyone modificatio...

@ziss_dm - yes yes please!!! Maybe it is revolutionary way to use this very good (the best for now) gyro in their native, full resolution, without desoldering/reflowing this small piece of sand And also the cheapest way -$40 from sparkfun BOB seems to be too expensive but clone WMP about few bucks s...

Maybe it is a problem with inactive pullups resistros in Arduino....I observed that buzzzer beeps abnormally when something wrong ocassionally did on Ardu board like I2C freeze, initalization, calibration...there is small, short (above 0,3sec) beeps... I think in this case S3NS3 have a problem with ...

Hi guys, especially @spagoziak - in this thread we discuss about strange reading from ITG3205 included in WMPclone.... I know that another ACC maybe can be better, we all know about it...here we try to resolve the oversensitive WMP's with this superb gyros...please hold the issue...if not - we do th...

There is no problem with NK....when I attached WMP (with IDG655 gyro) and NK (nevermind which one NK - ADXL335 or another one) everything is fine. This problem seems only with newest ver of WMP (with ITG3205 gyro) attached to every NK. Single, standalone WMP from this new 2011 batch (ITG3205) workin...

THX Alex! I think, probably our chinese friends make a some mistake in microcontroller code WMP onboard....I have also properly working WMP with ITG3205...they are marked as ver1 (signed onboard)....these poorly appearancing WMP with ITG3205 are marked as v1B (or something like this - these WMP boar...

There is a problem, such as colleagues report... in my next batch from a supplier, I got several pieces of WMP with the gyro ITG3205 and unfortunately they are "over-sensitive"on each axis - Look at my GUI, if I make a sudden movement then the value for a particular axis gyro reaches a max...

Yes, I implemented such function (in conjunction with piezo buzzer) on my PCB shields for nano and pro mini. There is a special connector for LED stripes 12V (not D13 output) and it works as you described. Also piezo-buzzer sounds up (LED stripe now is blinking) when the batterry is low (three level...

Are soldering instructions same as arduino Mini?
thanks

I took up the production a dedicated PCB shield for Ardu Nano, you can see this on my RCG's blog

Hi, thx to Alex for his great project, also with idea to make this place! About ITG3205 - it works great in GUI, in beetween a few days I try to fly with this sensor and report how it works in the air Here is my WMP clone with ITG3205: http://img156.imageshack.us/img156/6154/itg3205.jpg Uploaded wit...
