MultiWii

Leo

My recommendation is to switch to INAV (https://github.com/iNavFlight/inav/wiki). It does everything MutliWii can do and more.
You will need a new FC but the switch is worth it. I've since moved on to INAV and Betaflight.
For sentimental reasons I will keep one MW quad copter as it is still a lot of fun to fly.

Leo

OK, I'll answer then.... since I've looked at your thread

Sorry, but I haven't clue on how to solve your problem

Leo

It worked out of the box. I only had to make sure that the baud rate in MW is set to the GPS module.

Leo

I'm posting this for those who are still flying MultiWii (anyone???) and have wondered if the latest uBlox GPS receivers work. Answer: They do I'm using this model: https://www.banggood.com/Ublox-NEO-M8N-Flight-Controller-GPS-with-Protective-Shell-for-PIX-PX4-Pixhawk-p-1005394.html I hooked it up to...

Leo

I have the same board as you. I had to use an external MAG and keep it about 120mm away from all wires. Onboard MAG is deactivated.

Here a picture of it in flight taken on 18. June '17:

Leo

Make sure your MAG is far away from the electronics particularly power cables.

Leo

So it's a receiver issue and not necessarily due to MultiWii?

Leo

Nice one Metori.

I already have an external GPS/MAG mounted. But at some time I'll try MahoWii again.

Leo

If I do try MahoWii again some time in the future I will report here

Leo

I'm using Ublox 6 as well....

Edit: I edited the last sentence in my last post and changed it to something more diplomatic

Leo

Thanks for your answers. It is much appreciated as is your work but nothing you answered is going to help in my case. I've been using MultiWii for many years and I know my way around When I say I reinstalled MultiWii 2.4 and everything works as it is suppose too, then that would mean everything you ...

Leo

I can't help but I'm hoping you will find a solution

Leo

Unfortunately I could not get MahoWii GPS Hold to work properly. So today I reverted back to MutiWii 2.4, set my settings accordingly and tried GPS Hold. Even in the wind we are having it functioned as it is suppose to. Therefore I will be staying with MultiWii 2.4 unless someone can figure out what...

Please do so. Then we could exchange experiences.

Leo

Leo, So I have some Crius AIOP boards that I want to put in a 450 quad for old time's sake. They were my first purchase and MW 2.2 was the first thing I flew. Have you figured out the GPS hold? Can I fly waypoints with EZGUI? I assume this has EOSBANDI's navigation code incorporated? I'm still work...

Leo

Hi Mahowik, I finally was able to try your version and I have to say I like it. Well done. I'll be doing more testing with the firmware and I'm looking forward to it. Right now the only problem I'm having is getting GPS Hold to work properly. The copter starts to fly bigger and bigger circles. My fi...

Leo

Steve,

you will have to solder the GY to the MB with wires as follows:

5V -> VIN
OR
3V3 -> 3V3
AND
GND -> GND
AND
SDA -> SDA
AND
SCL -> SCL

Leo

Leo

Very nice. I will certainly give it a try over the winter.

Leo

In "config.h" look for this and activate it:

//Enables the MSP_WP command set , which is used by WinGUI for displaying an setting up navigation
#define USE_MSP_WP

Leo

I won't be able to help you much but the first thing I'd do is to remove all the cables and devices from the board.
With only the board itself hook it up to the computer via USB and try uploading the code again.

Leo

I have two QC's and both fly with MW 2.4. I don't have any experience with other FC systems but for me don't see any reason to switch.

Leo

That's great news! However, for the record. Your prior setup should have worked just the same. I would guess that you have a defect on your FC board. All positive pins on the Crius 2.x FC boards output 5 volts . I measured mine on the IC2 Port just to make double sure. I only fly these FC boards btw...

Leo

I checked the picture and added the port descriptions:

Assuming the white and the yellow wire is the same I'd say the connections are correct.

Leo

This is how I did it on my V2.0 board:

Leo

Well, I am very happy about the news! I don't plan on switching to any new hardware. MW and 2560 work fine for me. However tweaks e.g. filtering and cleanup wouldn't hurt any. And I'm sure other platforms e.g. Cleanflight have improved algorithms that could be implemented in MW. I would also hope th...

Leo

Here is an example of my position hold with MultiWii 2.4. I'm sure it can be improved further through PID tuning.

Leo

With the latest GUI I can't edit my Waypoints without having to connect to the FC first. Is this on purpose or am I doing something wrong? When I enter "1" for auto landing in the Waypoint "RTH" it reverts back to "0". Error in the GUI? There shouldn't be a error in gu...

Leo

Yes, MultiWii 2.4

Leo

Nicely done

Leo

... You can change the land speed in centimeters per second in the GPS section with the #define LAND_SPEED 100 by changing the 100 to something less which could result in a smoother landing. My question for you now (for fly4fun, as he was wanting to know) is can you do a RTH and then flip a switch ...

Leo

Today I did my quick first tries with the autoland option in MultiWii. The autoland function was activated via switch on the transmitter. I wanted to make sure it works before setting it up on EZ-GUI. The settings are stock and it seems to work good. I will have to check and see how I can tweak the ...

Leo

I haven't tried that function either. Since I now have a backup QC from spare parts I had lying around I'm going to try it out too. I'll post a video of the flight as well. In the mission function when you draw the land waypoint and click on it to open it for parameter editing, you can set the alti...

Leo

@ezio, there is a bug in the latest version, in mission planner. If you draw a mission path, and select last waypoint as LAND, the distance is not calculated correctly - the length of the last segment is missing. This can be serious problem, because someone might send the copter too far, fooled by ...

Interesting.....

Do you have a video e.g. on YouTube that gives an overview of the www software in action?

Leo

Under "Tools" -> "Programmer" you should have "AVRISP mkll" set.

Leo

Check out your own eBay link concerning the board and look at the specs....

Then you should realize what you are doing wrong....

Leo

You are wondering correctly because you don't need a FTDI cable to program this board!!

Just use a standard micro USB cable and plug that into the USB socket on the board and the other end to your USB port on the computer.

Leo

Yes sir, 100% correct

I have a Samsung S2.

Leo

Thanks Bart

Leo

MultiWiiConf is programmed with http://processing.org/, not Arduino.

You will need to download version 2.2.1. for MultiWiiConf.

Leo

Hi Ezio, I just downloaded Version 3.6.216 and I can't figure out how to use the app. The former config page is no longer available so I can't select which one of my 4 Blue tooth Quads to talk to. John I have the same problem. It doesn't matter if I have my phone upright or tilted. The dotes don't ...

Leo

Thanks. I just wanted to make sure that I've done everything correctly on my setup.
To compensate I think I will just add 0.3V using "Voltage adjust" (edit 2) or set the alarm lower by 0.3V.

Edit: For reference I'm using v1.5.2.0 - R1.6 pre.

Leo

I need some advice concerning the display voltage option. My OSD board has this option. I have it connected directly to the lipo (plus) to read voltage. I set up the display as stated in MWOSD guide "Calibration". Fully charged 3S lipo at 12.6 volts. Adjusted it to 12.6V on the display usi...

Leo

Thanks for this. I've updated my code on both my QC's.

Leo

Nice setup. You're going to enjoy the FPV flights.

Leo

Give this a try: http://ez-gui.com/manual/multiwii-clearflight-wifi-to-ezi-gui-how-to/

Leo

Guys, when posting the code please use the "Code" tags. Makes it easier on the eyes.

@JFRouh: Please post your complete config.h and post exactly what hardware components you are using.
