Don't know if there's any trace that can be cut, but I ended up in removing the whole 5883 sensor from my Flip32+. simply used a small screwdriver, to lift (break) it off the board.... went quit easily, and didn't cause any shorts / damage beyond the 5883. YMMV. Once the onboard mag is gone, check i...

sure it will.....

Hi everyone, just flashed cleanflight onto a naze32 r5 (full) and am having an issue with telemetry from my FrSky dr4ii to taranis......? I have the Rx connected to the middle pin on the bottom row of the 10 naze pins (which is where it worked with baseflight) I have enabled feature soft serial but...

Does it have power ?
not all flight controllers provide 5V on all output pins.

You might have to get the 5V from somewere else.

wilco1967

GPS code: There are some important bug fixes compared to baseflight but the experience is otherwise the same. Harakiri GPS code is being looked at and understood and then it will be ported. F4 targets are on the radar, but not yet. I accept pull requests Hi, Have a Flip32+ board since a few days. i...

in principle, for a tri, it doesn't matter what props you use.... they could be all CW, or all CCW, or a mix.... with all spinning in the same direction however, the tail servo will have to be tilted more, to keep it straight. Also, when flying fast forward, a tri with all props spinning in the same...

You can reverse yaw servo in the gui, under the servo settings

wilco1967

Alright, glad to know that solved it.... BTW, if your looking into controlling the camera pitch from your remote, you could modify the MW code slightly... change: (in output.cpp) #if defined(SERVO_TILT) servo[0] = get_middle(0); Into #if defined(SERVO_TILT) servo[0] = get_middle(0) - rcData[AUX4] + ...

Is there 5 Volts on the centre pin ????
not all boards provide the 5V on pins 43-45 (for Mega, not sure for promini)

Hello, Been flying with NAV version B7 on both a quad and a tri almost since it came out. Seems to be working really well. However, I'm not 100% sure what happened exactely, but today I had again an issue with the quad where automatic throttle (baro) would not disengaged even though all aux switches...

I finally got hold of a Taranis to replace my 9X Taranis works exellent, but now I have some small issues with the Frsky telemetry from multiwii. All was working fine with my old 9X running openTX. Using the same receiver (D4R-II / D8R-II), the telemetry data is visible on the Taranis, however some ...

wilco1967

yes, works fine with MW 2.3 ....
no problem.

OK, good to here it is (at least partly) solved.... Magnetic interference is something we need to live with.... try to locate your compass as fat as possible away from wiring (esp high current motor / battery wires). I've put my compass on a little wooden stick, away from the rest. Sometimes a few c...

Hmmmm.... very strange.... eprom_clear is a program in arduino. you select it from file / examples / eprom / eprom_clear then you simply compile and download it to your controller (make sure you have your board type and com port set correctly).... after download, it will just take a few seconds to c...

wilco1967

one more thing..... please try an eprom_clear. there have been a lot of instances, where strange behaviour was resolved after clearing the eprom.... Not trying to be rude, but is your battery really up to the task ? I ask because you wrote you checked it with a voltage checker, but was that during f...

wilco1967

OK.... 1050 .. 1950 should be fine.... however, the lower the full throttle, the lower the motor power will be, but 1950 should be plenty. I would still give it a try at 2000 maxthrottle, made a significant difference for me. Did you check in MultiWiiCconf (gui), under the settings tab, if everythin...

wilco1967

Strange.... first thought is weak battery, but I assume that would have crossed your mind already, and it wouldn't fly on KK as well.... The 2560 boards are not really different from pro mini in setup These might be obvious, but did you: - calibrate ESC's ? - set the transmitter so all RC values in ...

Hi, I've been a happy user of EZ-Gui for some time now. However, since the last 2 versions (currently 3.7.123) EZ-GUI will crash frequently. It seems to start fine, but latest as soon as I call up the GPS map, it freezes, and there is no-way to get it to respond to anything anymore. It's not always ...

On a rocket, you might want to disable stabilization after the apogee is reached.

Tried EZ-GUI (latest version) yesterday again after over a month without flying. Seems like 'Follow-me' does not work correctly anymore.... When I activate follow me, the copter moves off to some far-away destination. Did not get a change to properly check where exactly it was intended on going, as ...

Hi Tovrin, Thanks a lot for that tip.... That works beautifully To clarify, for others having the same issue. - Start MWgui, - let it activate BT (if not active already) - hit the android menu button, this will bring up the option Disconnect - select disconnect - directly after that, select MW conne...

Hi I'm using EZgui with a bluetooth adapter for some time now, and its working great.... However, sometimes it is very difficult to get the BT module and my phone to connect. I many times get 'unable to connect'. Sometimes takes a few minutes and many tries with sometimes exiting EZGui as well as sw...

Hi Alex, Thanks for the update... Flew today at my normal location again.... Flew 8 batteries, and not a single issue... All perfect. Perhaps indeed a good idea, to not accept any adjustments, if armed. However, I heard of some people doing tuning of parameters, while flying. I also tried that a few...

Hi, Not sure if I'm writing in the correct thread, but here it goes....

Perhaps not the right place to ask, but a lot of readers here might have the same question I finally got an old android phone, and have succesfully used it with MultiWii EzGUI and a bluetooth link through Alexinparis's great UART radio project (433 MHz control + serial link with HK orange module).

Not sure if this has been discussed, but perhaps the jump on yaw effect for a quad might be caused by non-linearity of the RPM to thrust characteristics ? perhaps I'm totally wrong (most likely), but I was wondering if for example a 10% increase in speed (or better, 10% increase in demand signal), w...

Hi Mgros,

Thanks a lot !.... that one compiles fine,
I'll customize that for my tricopter setup later today ...

Confirmed..... works beautifully
Thanks a lot !

wilco1967

Try in FrSkyTelemetry.h this ..... Hope this help. Hi mgros, I'm struggling with the same problem. Could not get it to compile yet , even with your code, but thats probably because I copied something wrong. Could you perhaps post a zipfile with your complete MW code, including the FRsky telemetry, ...

Hi Alex, Works beautifully on my old tricopter. Even with mag deactivated (aux switch off, but it is still in the config), the tri will hold its heading much better then in earlier versions with mag (heading hold) active. When I hold it in my hand, and force it into another heading, it will forceful...

I've been using the FrSky telemetry now since almost when this thread was started, and I really like it. But now the dev's changed the structure of MW, with the .cpp and .h files. Did someone get the original FrSky_telemetry.ino working in the new MultiWii format ? I did get the new MW to compile wi...

Hi, I think I found at least one problem in software which leads to data inconsistency once it occurs. It should be corrected in MSP_RX_TX5.zip in the first port. with this one, I didn't managed to reproduce a long break in the link communication. Hi Alex, Seems to work now.....

Hi, Wasn't really conviced my problems are electrical..... So I went back to the OpenLRSng firmware. No problem whatsover.... never lost control, without even the slightest glitch. So I think this means, its a software issue of the UART radio code.... It works fine when there is a clear signal, but ...

Indeed, not a single loss.... Also flew out far again, all OK super ! too bad the module is so voltage sensitive, just something to care about in the setup. I think this conclusion was a little pre-mature.... Did quite a few other flights, and lost the link on nearly every battery at least once. Tr...

Hi, Thank you for testing. Thank you for providing all these great projects I understand you use the frsky backup in this case So, I managed to reproduce the problem, but I'm not sure the root cause comes from the soft.

Did a testflight yesterday with the new (ver 3) UART radio code, with mixed results. Ranges seems to have improved.... managed to fly out 537 meter using the UART radio for control.

Hi, I've just uploaded in the first post a new revision (RX_TX3). This should be more stable regarding RC data, as MSP_SET_RAW_RC is ensured to be transmitted in case of congestion.

Allright... some more findings. happened that my tricopter actually had a older version of the MW software.... (still had the RCserial statement in it) updated to the latest dev 1432.... With that, at least I can read the GUI data, as long as I leave the controls through my normal Frsky receiver.......

wilco1967

yes, normally you should..... however, you still might have to power the MW with a proper 5V supply (from an ESC or UBEC, or similar) USB power alone often is not sufficient, causing all kinds of strange behaviour. Please remember to disconnect the 5V pin from the FTDI to the MW when using another p...

yea, I know about those (at least similar)..... I was just hoping the OpenLRS could do something similar....

wilco1967

may I ask, why are you using a 5V BEC ? HK descriptions says: Voltage input: 3.7~15VDC. At full TX power and 12.4V input, the DC reducer of HK modules get really warm, and I finally fry a module like this. That's why I prefer to reduce DC via a BEC. I don't think genuine OLRS modules have this prob...

Hi EOSBandi

Good work !
small issue.... seems like the motor indicators are not working (at least) on a quad.
for tricopter, it is OK....
