I've added the option "f.GPS_BARO_MODE = false;" as described and took the QC out for some tests. I didn't encounter any problems but need to do more flight variations. However I would greatly appreciate if the codes could take a closer look at it as I don't know if any other functions wit...

Here a video I put together showing 2 identical navigation missions flown 15 minutes apart. I have made comments in the video where I thought there are some anomalies (nothing serious) I do would like to know what the causes could have been. Maybe small glitches in the nav code?

No, it won't. That is why I switched to a 2560 mega FC. I would recommend you do the same.

Leo

I believe I found a bug in the Nav code. I was flying my quad, and had gps hold and baro enabled. I wanted to bring it down, so I flipped off baro mode. Problem was it was not coming down. It was descending slowly as if baro was still enabled. Turning off gps hold allowed me to control throttle aga...

Leo

Thank you. I learnt something new again

Leo

Alex, please also take a look at this option concerning BARO and GPS Hold: http://www.multiwii.com/forum/viewtopic.php?f=8&t=5852&start=50#p61959

Possible issue: http://www.multiwii.com/forum/viewtopic.php?f=8&t=5852&start=50#p62032

You will have to cross 2 of the 3 cables to reverse motor rotation. It doesn't matter which cables you choose.

Leo

Yes, CRIUS_SE_v2_0 would be correct.

The problem with your board is that it doesn't have a reset button. Otherwise TTL would work but it would also be very very tricky to get the correct sequence for firmware upload.

Leo

You will need a FTDI board as pictured in this ebay ad: http://www.ebay.com/itm/CRIUS-MultiWii-MWC-SE-FC-V2-5-Standard-Edition-Flight-Controller-Board-FTDI-/261501364969?pt=LH_DefaultDomain_0&hash=item3ce2b22ae9

Leo

That's great guys. Good to see I'm not the only one

Leo

I don't typically land with GPS hold enabled, and that wasn't what I was doing when I discovered this bug (I know I wasn't clear). When I found the issue, I flew the quad over a patch of land with no trees, enabled position hold, and then ascended to a height (100m for example), then engaged baro h...

Leo

Do you think it is a good idea to have GPS hold active when landing the quadcopter?

Case in point: Your quad is just about to touch the ground and GPS PH makes a correction and the landing skids get caught. Worse case is the quad could flip over

Leo

I'm trying MultiWii OSD for the first time. I hooked up my new board and flashed the latest firmware R1.3.

Bug: When I set the "Time Zone Offset" to say 2.0 and then do a "WRITE" the value will change (display) to 0.2.

Leo

So I'm enjoying the leftovers from the party a year ago? OK... I can deal with that

Leo

I've been doing more or less tests to see that mission navigation is working properly. I did change baro calculation from float to integer on this flight in preparation for optimizations in smoothing out the readings. I will continue when 2.4 is officially out. RDAOqBvfwfk Am I the only one flying m...

Hello Leo, where you bought aiop 2.1? I can find only 2.0 everywhere. I purchased mine here: http://www.ebay.com/itm/CRIUS-All-in-One-Pro-V2-1-MultiWii-MegaPirateNG-ArduPlaneNG-Flight-Controller-/251714163029?pt=LH_DefaultDomain_0&hash=item3a9b555155 I made sure that they are selling v2.1 by as...

I'm sure that will happen

This evening I did 2 identical flights that used the exact same navigation route with some interesting observations. I should have the video up tomorrow evening. I also made some pictures during the flights. I think this one is cool: http://www.leo.nutz.de/images/helicopters/forums/Quadcopter_Moon_4...

Leo

Bart, I had very bad 3DR reception. The data is almost useless.

However if you can wait and the weather is good tomorrow then I will do the same flight again and will use a longer rod so the antenna is higher of the ground.

Leo

When I'm happy with everything and all is working fine on my QC then my next project will be to install MWOSD

Leo

Thank you.

I'll be using this route for further test. However I've added 5 meters to the altitude as the QC was a bit too low for my taste particularly flying from WP5 to WP6

At WP5 the QC seemed to be confused for a second....

Leo

I had some fun testing various items like NAV settings and quality of my FPV hardware:

Leo

The new videos are much more meaningful. I have the strong feeling your ESC's are not calibrated correctly. Before you calibrate the ESC's you might want to check if your stick settings on your remote are set to -125% and +125%. That is how I set mine up. You can also calibrate all ESC's at once by ...

Leo

Google is your friend. However you will find the connection description on page 42 in the link I gave you.

Leo

If I did my research correctly the numbers in the diagram below should correspond with the numbers on the FC.

Leo

If you had a Quad then it would be simpler for me

You can always start by looking at eBay.

I strongly suggest you get a bec with 5.4 Volt output to power the FC! Some info here: http://www.multiwii.com/forum/viewtopic.php?f=18&t=5940

Leo

Ok

I seems to me then you will have to start looking at the hardware. Check and see if ESC/Motor is working correctly.
One test would be to use the "#define DYNBALANCE" option to check each of them individually.

Something that comes to mind: How are you powering the FC board?

Leo

Well, I trust you have read and done all the recommendations posted at the beginning of this thread like read the Wiki.. ESC, ACC and MAG calibration and so on... I took a look at your video and frankly I can't tell that there is anything wrong only because you are hardly doing anything. The copter ...

Leo

Phold and RTH will work just don't set up navigation.

Leo

It should work fine without navigation enabled. I had it running on my old board.

Leo

Hello to Everyone - Thanks to all for doing awesome work with the updates. Got r1739 loaded and working with the WinGUI_2.3pre10(b7). One thing - the POI doesn't seem to work. I tried to setting a POI before each waypoint, as well as just one at the beginning with no luck. Is there something I may ...

Leo

I'm curious... What's holding back the release of 2.4 and WinGui 2.4 ?

Leo

Well done on that!

Yea... turn off your oled for now. //#define OLED_I2C_128x64 // I2C LCD: OLED http://www.multiwii.com/forum/viewtopic.php?f=7&t=1350 //#define SUPPRESS_OLED_I2C_128x64LOGO // suppress display of OLED logo to save memory I'll say it again.

When I first saw the picture I thought... who spilled the spaghetti on the copter Taking a look at your configuration I immediately noticed that you have the wrong board configured! If it's the same board that is pictured in my post then you need to activate: #define CRIUS_AIO_PRO_V1 I have Max Thro...

Leo

Let's have a look at your conf.h

Leo

Right now I don't have a clue due lack of information.

How do the bars in MultiWiiConf react when you arm the machine (without props!) and move the gas stick?
Do they all more or less move the same?

Leo

Are the motors turning like in this diagram: http://www.multiwii.com/wp-content/uploads/2011/01/HEX6X_mega.jpg If you can I would recommend you use the latest pre 2.4 code and also use MultiWiiConf: https://drive.google.com/uc?export=download&id=0B8_pEI-_SlWGVWYtRTJRTG5JVmM

That last thing you want to do is give up. We'll get this thing up....

How about you recap on all the hardware you are using. Makes it easier for me (us) to help.

Leo

Translated with Google: "if Fence radius is < Safe wP distance would have to abort mission ???????"

Leo

Eizo, what version do I configure in EZ-GUI if I'm running r1743. 2.3 Nav or 2.4?

Leo

P and I are stock or did you guys set them up to best suite your machines?

Leo

The Pololu board has a LPS331AP baro chip and it is the worst I've ever tested. http://forum.pololu.com/viewtopic.php?f=3&t=8168 I'm saying this in case you want to use the baro chip in the future. Consider this one instead: https://www.pololu.com/product/2470 However I haven't tested it so I ca...

Leo

Thanks Leco,

I will looking onto making the LED's of better use for our boards. In my opinion it is enough to only have 1 LED to signal arm. Just have to figure out what the 3rd LED could be used for

Leo

OK, so you can't spend a million... then we have to take the cheap route.... I have this GPS/MAG unit with my Crius AIO Pro V2.0: http://www.ebay.com/itm/301293637300?_trksid=p2060778.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT I hooked it up like so: http://www.leo.nutz.de/images/helicopters/foru...

How much money do you want to spend?

That is a Crius All In One Pro Version 1.0 board.
