Hi. My Mag is calibrated, but it is 50degrees off compared to true north! I must rotate the FC 50degrees CCW to point the GUI arrow towards N.. How can I use this in my declination? Just wondering if you have some magnetised nuts or bolts near the magnetomer? You could perhaps check with a small co...

Hi Realpastaman.. I am having the EXACT same problem as you describe! When i throttle up it deviates 5-8degrees maximum. I have been using the mag declination value for Bergen, Norway of -0.33f. When i flip it to TRH, it rotates 30degrees as you encounter (approx), and starts to move in that direct...

realpastaman

Pleased to say that the 30 degrees CW yaw has now gone completely and RTH seems fine now. I would appreciate a RTH programmer or anyone else to comment ... a) Is a 5 degree shift in mag reading between throttle 0 and throttle at hover that significant? b) How important is it that after doing a compa...

realpastaman

Having had some time off work, I think I may be getting somewhere with this! Usually we get magnetic declination from the internet. In my case it Brighton UK (Well Hove actually) its ~ = -1 Given the nice weather, I performed another compass calibration and then lined up the quadcopter with true nor...

realpastaman

With the props off, I power up all the esc's and just plug the esc's one by one into the throttle pin of a rx and then throttle up on the tx to test the direction on rotation one by one.

I have a quadcopter AIOPV2 and Ublox NEO-6M GPS v2 Mag is calibrated well and AIOP is not affected by power lines as it is raised and i have been really careful with power line routing etc RTH (tail first) is working but with the following problem. As soon as I initiate a RTH I see the quadcopter im...

Andreas, take a look at this and load the loaded the config file to the GPS. It worked for me with a similar problem. http://www.multiwii.com/forum/viewtopic.php?f=8&t=3431&start=40#p36407 Yeehaa, it works now after configuring the Ublox with that config. Thanks a lot! Ublox accuracy is eve...

Hi Guys, I've a strange problem with my UBlox GPS from RCTimer. If I power the Crius AIO with the USB connector and start MultiWiiConfig, GPS data is received and I get a satfix. If I power the FC with the Lipo, I don't get data and satfix - but the GPS Module gets proper power. It comes with defau...

ok, here is the video m as you can see the yellow led never flash... you can try maybe 10 times to reboot the FC and then it works... loaded the 2.1 and works fine...

Running Multiwii 2.2 AIOP V2 has shottky diode shorted out so as to give the board 5V I notice that on power up, sometimes the board does not seem to communicate with the NEO-6M GPS v2 whilst other functions on the board are fine. This can sometimes can be solved by other power up cycle or always so...

I have the Minim OSD working well on my 328 based Pro Mini 328 based flight controller.

I understand this now has to be done by using the the lcd.conf menu to tune vbatscale until voltage displayed equals battery voltage.

I'm really not understanding this lcd.conf menu! where do i find it?

Can someone help me to see how this is done - I dont have an lcd for multi wii

Thanks

Using a single baro mounted on the flight controller, the altitude can drift several metres due to normal changes in atmospheric pressure. I had an idea to incorporate another baro in the tx and transmit this reference air pressure to the flight controller. The flight controller could then use the r...

@Realpastaman, thank you for your reporting your experience, we appreciate that very much. The font uploading is not working on the released dev r280, that is why you see strange stuff on screen.

realpastaman

choose RC to get close to cycletime; I use 100nF (and 10k ?) Averaging is done is Multiwii.ino. Search for vbat and assign the vbatraw after scaling directly. If your values are more stable than with the old 33k+51k values, then you do not need averaging and you get more precise changes. Thanks Ham...

realpastaman

Anyone else having problems with higher than expected Vbat with the correct 5 Volt supply voltage. Or having problems with drift over time / temperature should try this. You say with your lower values you do not have such issues, even without the RC filter? If so, you may be interested in removing ...

Well, I am not having a problem with the zener itself but the 8bit vbat variable in the MWC. Using the Zener, we get almost the full range(1024 steps).

I am not using R3 at present, I am using R1 = 1K, R2 = 10K and the Zener = 8.2 volts Hmm I'm really not sure on your circuit if there are any problems due to high the impedance presented to Analog pin 3 or not. I haven't got an 8V2 zener to hand to experiment. I'll get one from Maplin tomorrow and ...

Hmmm, you may be onto something here. I am using the zener method talked about there but Iused much higher resistor values than prescribed. http://www.multiwii.com/forum/viewtopic.php?f=6&t=2661 A would expect quite a bit of variation from chip to chip is its running outside normal parameters t...

I am using R1316 on a 3S Lipo and getting a much higher Vbat than expected.

I'm from an electronics background.
