WRONG!

^ Go get a fucking naza if you can't fly ^ especially autoland, rofl. that garbage will make it into baseflight over my dead fucking body. Lol, okay... :j Some of us geeks like flicking switches and watching things happen instead, certainly not everyone's thing... It's a neat multiwii add-on, sure ...

felixrising

All of those features, PH, RTL, Altitude Hold and Autoland are available on MultiWii too, using 'Altitude Hold/Advanced Failsafe solutions by NHA' http://www.multiwii.com/forum/viewtopic.php?f=8&t=2965 . I personally prefer to be able to fine tune settings for each variable, I'd be frustrated by...

felixrising

Can you take a video of it? Remembering that it won't hover without drift when only a few cm from the ground due to ground effect/turbulence.

felixrising

So we have PH, RTH and Autoland working? Also as part of Failsafe? Awesome :p

felixrising

Totally agree with Rotary65. For me, this is about the learning experience, it's just fantastic being able to dig deeper and deeper into this great OSS project, and also have the joy of flying it knowing what's going on in the background. For me, the tweaking and at times complexity is part of the e...

What makes it "better"? Control over the hardware. Software is a small factor in this. Having so much choice in hardware makes software setup more complex. There are things that can be done to introduce a more consistent out of box experience (HAL), but at the end of the day, if I set up t...

felixrising

A HAL isn't really needed to fix this, just using the correct scale factors can't be that hard, and it would make people's PID values more consistent. Adding the correct scale factor for Gyro and Acc(!) under "Sensor Type definitions" for each sensor in def.h and updating IMU.ino would be ...

Hi I think there is something related to MAG_DECLINATION broken under 1411, it was fixed in 1414 it seems. Would this be an issue for r23?

felixrising

Great. Nice work. Just a tip on setting trims - You should really follow the intructions on Transmitter Calibration using that last link I posted. You should never try to level a MultiWii quad using transmitter trim. Transmitter Trims (preferably sub-trims) should only be used to get your centers ri...

Hi Nanobot9000. Have you used MultiWii before? Are you familiar with the MultiWiiConf? 1. I've got a DX7s, so probably not too different (hope I'm not talking out my bum here) You can use either heli or plane, it's really more about channel mixing so plane appeals to me more due to it not mixing thr...

Hi Adrian, I haven't had a chance to check out the updated version yet. I should have some time on Sunday. In the meantime, I've just been thinking about the Advanced Headfree mode which made it into _shared. Nice work on that! There have been some requests around a virtual fence mode, which would b...

To protect Pilotlamp's signal line, add a 1Kohm resistor in series before plugging into flight controller. Adding another 1Kohm resistor for pull down is recommended for signal integrity. This needs to be in the wiki too. Someone else also left a comment on the wiki indicating something similar.. I...

The only problem here is that the ublox gps when used with "#define GPS_PROMINI_SERIAL" (to auto detect when the GPS is connected) compiles too large to work on a HEX6X platform. Its small enough under a QUADX though but that doesn't help me. Is there some other way to configure MW and spe...

felixrising

Hi Adrian, I notice when I try and enable RTH_ALT_MODE but with AUTOLAND undefined, Arduino throws an error: MultiWii.cpp.o: In function `loop': /Applications/MultiWii.ino:1777: undefined reference to `altToAutoland()' I don't want AUTOLAND feature enabled (to save memory), but would like to have a ...

Better, put a combo stick, with motors disarmed, throttle down, yaw center, pitch up for 2 secs - enable gps serial, pitch down for 2 secs- disable gps serial and back to gui. Hi, did a combo stick solution get implemented? Any code snippets to implement a gps stick combo enable on serial 0? EDIT: ...

felixrising

Sorry to hear of your troubles Dramida. I've done a few PH PID tweaks whilst airborne via bluetooth dongle but thankfully didn't experience any system failure like you've described. I did notice that the engines would briefly spike but nothing major and ultimately settle very quickly (<1sec) after t...

felixrising

I have this same problem. Did you find a solution? I'm using a dodgy HK NanoWii. I think it's just that the Spektrum port shares some or all pins of the FTDI interface. I'm not sure but that's what makes sense to me.. everytime I touch the Rx Bind button the GUI just crashes. I've resorted to using ...

felixrising

It's not that things just crash or there is some other catastrophic bug, it's that failsafe detection has 985 as a threshold value by default (look at RX.ino for "#define FAILSAFE_DETECT_TRESHOLD 985"). Personally I adjust this threshold up to 995 because my Rx failsafe values don't seem t...

felixrising

Well that is just like foreplay without the sex.

There's OSD?! Other than mobiDrone or MinimOSD? Do tell.

felixrising

NAZA?! NEVER!!! I think there will always be people who like to cram in as much code as possible into the tiny controllers, but at least you've got some nice hardware at a reasonable price (I'm looking at you Autoquad 6) to give people an incentive to move to 32 bit. Anyway, it's cool to see the fea...

Hi, I'm still waiting for my naze32 and a couple of afro mini 32's to arrive, so doing a bit of research, one thing I'm wondering is how best to get some of the features I've been playing with onto these more powerful boards.. namely I've been using nhadrian's "Altitude Hold/Advanced Failsafe s...

felixrising

You might like to look at some experimental code by Adrian "NHA", it's got some extra code with regards to vario. http://www.multiwii.com/forum/viewtopic.php?f=8&t=2965&start=160

felixrising

Yeah, I've been doing some reading on sensor fusion, looks like some people much smarter than me have already looked at this problem, fusing GPS + Sonar + Barometer with a transition threshold and doing some advanced kalman / complimentary filtering with two cases, one for below 6m (or whatever the ...

felixrising

Is this the same issue I'm seeing? If I roll the quad left or right, as it transitions from 89 to 90 degrees (Roll CW) or -89 to -90 degrees (roll CCW) it momentarily shows a value of -90 degrees from either 90 for roll CW (ie 0 degrees) and -90 for roll CCW (ie -180 degrees) respectively. I don't s...

felixrising

Hi Adrian, I've finally got a SRF08 sonar and was wondering whether you would look at integrating Sonar into your altitude/vario control/calculations? I see there are a few implementations floating around but it doesn't look like anything made it into 2.2 despite several sensor fusion solutions in f...

felixrising

I'm not sure what you call inexpensive, but I have a Walkera Devo running DeviationTX, which does DSM2 and a few others with a little soldering .. you might find a Turnigy 9x is a good option too, fully hacked by community with OSS firmware available and supports many modules including DSM2/DSMX wit...

I have a Flytron Navigator V1 GPS. I'm trying to get my GPS working with binary protocol, but it's not working. I've flashed the gps with 1.9 firmware. With Minigps set it to 115200 and 10hrz also tried 5hrz. With NMEA protocol it's working fine, but with Binary protocol I see nothing in the GUI. W...

Sounds like some PID tuning is required to reduce the strength of corrections.. there are a few posts on position hold tuning.. use the search and google to find EOSBandi's older but still valuable pdf document on PH and RTH nav tuning.

felixrising

Mystic3D. This is a very old thread, the last post was more than 9 months ago and the recent 2.2 changes included some improved altitude hold code. This thread should be marked closed.

felixrising

Thanks! Loading it up now to test it out.. r22 worked great, RTH, AutoLand, etc all tested out fine under dev1371, no changes expected under dev1379 but will report back. EDIT/Update: Okay, tested PH, RTH and Failsafe with vario. Works great! Two minor things: 1) it looked like it was RTH whilst ris...

What carbon fibre props are you using?

felixrising

Hi, Felix! The failsave will engage, if the RX fails to send it's normal pulses. This also occurs if a RX -mwii wire gets disconnected. The RX MINCHECK is irrelevant for this function on multiwii (i think arducopter has some kind of this throttle - approach in its code). So setting a fs in your tra...

felixrising

Okay, replying to my own post, I found this post m by bunnygirl80 which mentioned the failsafe detect treshold [sic] value in RX.ino... "#define FAILSAFE_DETECT_TRESHOLD 985" which indicates that throttle needs to at least drop below 985... okay, I'll try to rebind and set throttle below 9...

I've got some problem with failsafe detection. I've got a spektrum dx7s + ar6115e which I've bound to remember a pre-defined failsafe settings which are center for everything except for throttle which goes to 990.. any reason this won't let it go to failsafe? It just hits minthrottle and the quad pr...

felixrising

Looking forward to hearing how you go. I'd like to get mine really locked it but sometimes I get a bit confused which parameter I'm observing needing a tweak.. and it's really time consuming without a telemetry set-up.. the bluetooth is great, but it's range isn't more than a few meters :/

felixrising

I don't care how big it is, I just want to know where do I get one?! =D

felixrising

I've been playing with Pos Hold and RTH recently too. I have a Crius AIOP V1.1 and a V2 + CN-06 Ublox Neo-6m. I find that after initially enabling PH, it tends to drift off (today was windy) before correcting and finally settling. Often it will drift downwind about 5-10m before overshooting the mark...

felixrising

Although a little dated, OESBandi wrote this nice document.. it may give some insight to the various parameters. m Today I was testing and attempting to tune PH in 30kmph winds.. lets say I had to intervene a few times, and noticed that it drifted off a lot before meandering back with a bit of overs...

Hi, I did some tests on Sunday and liked the features! Nice work! One thing that bugs me though is the time limit before engine cut. This is something we can calculate instead of having a fixed time.

Hi, When I say compatibility with Arduino IDE must be maintained, it is especially because it's one of the easiest way to customize config and inject code in an Arduino from a zip sketch.
