The new flight controller finally came in. Was playing around a little last night. Can't get the ardiuno software to connect. Downloaded the FDTI drivers, but nothing. Hopefully get to play more tonight. Was doing some reading, this will still use the same motor layout correct? I was digging around...

Several choices here: m I bought the Pro 2 version and a leah 6 H GPS module. Not sure where I would hook up my outboard (on the GPS module)mag on this board if I were to disable the onboard one. Anyone have info on where to hook up your outboard mag if you cut the two traces on the onboard one??? ...

Well done Ezio. This makes programming & viewing logs of missions so much easier

Hello, I am having an issue with seeing the inputs from my radio in the WinGui software. The first board I had I had the same problem and hk wanted to test it. they determine that it was bad and sent me a replacement. I'm having the same issue were I can not get the multiwii to show it is receiving...

brewski

As I have said many times it is disgusting & dishonest that HK continue to sell these flight controllers with last generation technology. If that is not bad enough the quality control of the PCBs is well below par. Search this forum as well as RCGroups using this board description to see the iss...

Hi everyone, So I've been using this board for about a year now and could never get the GPS functionality to work. I could get signals when i was plugged into the laptop and watching the read outs in the GUI. But when ever i was flying the Pos Hold/RTH had zero effect on the quad. m So i just bough...

If your RX has failsafe memory then just select what you want to happen, such as RTH or Land & push failsafe button on RX. Mine is a Lemon 8 channel & failsafe works on all channels as soon as it detects signal loss.

brewski

Did you try holding it firmly from below & increasing throttle while watching MWConfig? As you increase throttle watch the compass. It should not deviate more than 5 degrees. If it does then the onboard mag is being affected by magnetic fields from wiring & will cause major yaw issues..even ...

brewski

OK so maybe it is still in my setup then. It is this board here m I followed the setup I saw there for which board to use, but maybe that is wrong. When I did the config file one of the setups I saw there said to use: #define FFIMUv2 // second version of 9DOF+baro board from Jussi, with HMC5883 but...

brewski

Use cheap FTDI (or similar)serial to USB adapter and reconfigure GPS in UCentre

No 'Z' is never zero. With MPU6050 you should have Z=512. What MPU does your board use?

I suggest posting in PatrickEs MW Airplane thread viewtopic.php?f=7&t=2456 & viewtopic.php?f=8&t=364 . Patrick has put links to his blog which explains everything you need to know about using MW with plane

brewski

Correct. I would contact HK & claim warranty. There are known issues with their MW AIOP as you will see by searching on this & RCGroups. They will probably send you another without returning faulty one if you document fault with screen shots etc. If out of warranty then buy a Crius AIOP V2/V...

brewski

It does not flash while calibrating ACC either. Does it need to be powered from the battery also while doing this? No just USB. Do your ACC X & Y values zero out in MWConfig when you start ACC Cal? If not try using MW WinGUI and see if it does. If you get no response from either then I suspect ...

brewski

Using MWConfig sitting flat on my desk in the Hex pressed CALIB_ACC and left it sit for several minutes. I am using MW2.3 with the config file adjusted for my setup. When I press CALIB_MAG the LED does not flash. From what I have been reading it should flash when doing this. The compass seems close...

Hi, Minthottle set to 1150, all props turning a consistent idle when armed. With this setting and some practise I now get perfect landings. All tutorial set min to 1000, max to 2000, as middle point is 1500. But we may speak about different settings? My root tx values without change to endpoints/su...

brewski

Yes I saw your mission using pre 2.4. Unfortunately my experience was not the same. I didn't check Solar activity that day so although I had 7 sats (by my GPS status LED) the GPS horiz accuracy may have been bad on the day I tested. I also had issues with EZ-GUI and WinGUI so was not impressed.

brewski

Well, I've decided to skip the tests and wait for the official MW 2.4. Then IMO after it's out the data logging code should be ported into that version. I've tried the pre 2.4 and found performance, especially GPS functionality/accuracy poor. Maybe I stuffed up but don't think so. Cleared EEProm (4...

Standard PIDs will get multi to hover. Did you cal ACC with multi level & totally still?

and here is the final part, the MultiWii code itself.

Cheers, Leco

Hi Leco,

I also have a Crius AIOP V2 & have asked many times why we can't access this EEProm as users of MP can.
Is base of MW code standard 2.3 or the 2.3 with navigation (Eos Bandi) that I currently run?

brewski

Due to http://www.multiwii.com/forum/viewtopic.php?f=8&t=5852 you can still use a 328 without a GPS device perhaps you can use a 328 with a GPS device but without navigation in no case you can use a 328 with navigation A state of the art flight controller running multiwii is based upon a MEGA (...

Wondering how this site is funded. RCGroups is obviously funded by Hobbyking & other advertising, but Multiwii has nil advertising.

brewski

If you look on UBlox site you will see that all 6 series are now discontinued. I have seen the UBlox 7 series going for less than the LEA6 & 7 series has faster acquisition & higher accuracy.

brewski

The LEA-6H is only same accuracy as 6M unless you live in Europe or Nth USA. An Ext Mag can be positioned away from magnetic fields, but the onboard Mag is not easy to disable on HK FC. Search this & RCGroups for details.

brewski

No. TX endpoints need to be 0 1500 2000. Set 1100 as Min Throttle in MW Config. The reason you need enough Min Throttle is to keep props spinning reliably & synced to prevent them stopping when throttle is set to minimum. If you need to rapidly apply power during descent you need all motors resp...

So, i have to uncommented The init gps, upload The code and then comment it again and select nmea? Can YOU post a link where to buy The ublox? And how to make it work? I would be verry happy Just use the Init MTK command. This sets module up for correct parameters every time FC boots. I don't think...

brewski

OK you have a known bad combination of FC & GPS. Search this and RCGroups with this combo to see. If you want to give it a try though disable NMEA & use Initialise MTK as this GPS will not work otherwise. The Ublox 6M modules are currently selling for <$15 & have faster acquisition &...

I suggest you read Beginners Guide viewtopic.php?f=18&t=5363
This should answer some of your questions.
Re the Spektrum DX9. I suggest just connecting up using individual cables for each control. You can worry about single serial data connection later.

Check out the HK Files section at bottom of product description.

Spot on. I mounted my ext 5883 on a CF post out front so well away from any fields, metal etc. You can also put a high Intensity LED or white ball on end to help with orientation.

I don't know about the 32bit FCs but my Crius AIOP V2 will not boot with BT connected. I installed a miniature switch & just turn on after FC has booted.

I think adapting WMC to run on the APM hardware would be a major step in the longevity of this project. As stated, with the availability of this hardware and the decision of the APM development team to suspend support, there is plenty of room for WMC to grow. I have personally loaded WMC 2.2 on to ...

Well 115200 is what my first Gps was programmed and i have been using it since.. Lately i have changed to 56.7k witch is supposed to be more accurate. It could be done by some changes in the code.

The patched I2C_GPS is unchanged in the serial communication between I2C and GPS. It's only modified to correct some old bugs in original code that only affect Fixedwing.

You should see the graph as well as ALT reading in MW Config. If you raise board 1m you should see change of approx. 1m.
Baro sensor requires a piece of foam (make sure air can pass thru it) over it to prevent prop wash & light affecting sensor.
