MultiWii

Nice idea, I guess.
Guess, because the first image shows a flying smartphone, while the rest describes a Smartphone controlled MultiWii.

Have you set your Minthrottle in the firmware high enough? Beware, in new Versions you have to set it in the UI and the config.h setting is ignored. Mine defaulted to 1050 which was too low to make the motors spin.

Gartenflieger

YAW-Direction is not longer handled in Config.h, you have to switch it in the gui. I think that is true for an increasing number of features/parameters. Guess how I found out. It is an improvement as it reduces the number of times you have to reflash the firmware. Maybe it would be agood idea to re...

Gartenflieger

Actually, I think you can use the vibration monitoring function within MutiWii, it must be enabled somewhere in the config.h and you have to reload the firmware without it again later, but probably easier than rewiring everything.

I might have stumbled upon a bug in the WinGUI support for the 6 modes per aux. After saving thhe settings to a file from WinGUI and reloading from that file, some of the settings are moved to the next aux channel. ( I observed it for aux1 and aux2) I assume the 6-mode-settings are not saved to the ...

Gartenflieger

So in the meantime you had some stable hovers, but the apparent power has reduced with each flight? In multiwii, unexpected power loss is sometimes caused by heavy vibration. If you feel safe doing so, you can hold the craft in your hand (or both hands withh a buddy at the Tx) while powering up to g...

I'm working on my first Quad. At first, it would get about 7 feet off the ground and then crash due to stabilization and mechanical issues. The altitude that it could reach gradually lowered on sucessive tests while I fixed the problems. Today, I replaced a motor and ESC that were damaged. On my fi...

Nice project! Let us see some video, please!

Did you select the correct board type in Arduino?

Gartenflieger

I suggest to just ignore all the ranting and it will stop by itself.

I see, is that behaviour in the MWii or in the GUI software?

Hi all, I have reassembled my copter after a while of abstinence. I downloaded the latest soft from EOSBandi, ans it flies fust fine. PosHold ans RTH work fine. However, when I ena le one of those modes, it is not shown in either Ezios app nor in The Wingui as active. Any ideas what could ne wrong? ...

Usually that's when camera doesn't match the pal/ NTSC settings. Suggest change pal/NTSC, save and reboot Yeah, that was it. After repeated CHANGE, WRITE, RESTART, RESET, LOAD cycles in varying order finally it is working now. Thanks for the hint. did a test flight and everything looks real good. R...

Hi all, coming from KV OSD 2.2, I intended to switch over to MWOSD R1. However, the OSD failed to overlay anything at all. All I saw was the camera video. When the camera accidentally switched itself off, I found out that the MWOSD overlay is actually displayed, but only as long as the input signal ...

Gartenflieger

i'd guess an INVERTER will swap the low and high levels of the signal, whereas a LEVEL CONVERTER will shift the high level to a different voltage. Am I right ?

Gartenflieger

Gartenflieger

great job, Shikra!
It seems a lot of people have been waiting for the release of the KV OSD. At least I was.
thank you for your effort.

Christoph

Gartenflieger

I have no idea. Maybe just run a search for RSSI.

Gartenflieger

You can either dig into the source code and remove it there or wait for the 2.3 release where the display items will be user-configurable.

Gartenflieger

I think the development is not actually going on in the google code repository.
Non-developers are supposed to use the 2.2 download.

Wrong, it means RTH has failed and you have a rogue copter. That is probably what the limit is supposed to avoid. So I'd say a second limit makes perfect sense.

Gartenflieger

A thought concerning the failsafe: I think the user should ALWAYS be able to interfere. I imagine there should be a test if the user has moved the sticks. If so, either abort whatever is done currently or modify the action according to the stick movement. For example: I see my copter returning home...

Is it possible the 2.3 takes a little longer to initialize the Motor outputs than the old versions? Every other time I connect the battery on my Quad, the motors won't beep as usual. In those cases the ESCs don't arm and neither does the quad.

Gartenflieger

On the tx, channel limits usually need to be set betwenn 125 and 150%.

Gartenflieger

Your 'servo travel" is probably too small on the channels, YOu need to adjust it to 1000-2000 us.

Gartenflieger

I would think that the PWM Motor Signal of the micro already includes the stabilization from the flight controller. So you will end up with two stabilizers fighting each other? Anyway, Obviously you are willing to hack all the was into the micro's board to find the pure teceiver Signal. regards Chri...

Hi Michele,

I have been thinking for a while how to avoid oscillations in fast flight on my Parkmaster (1m 3D parkflyer), particularly around the longitudinal axis, i.e. aileron oscillations. Of course I want high PIDs for hovering. One thing is setting the throttle PID attenuation. However, in downward flight ...

Nice to see this finally evolving into the code. I have always been too (lazy

) busy to port it to the frequently changing releases.

Use a 3DR to Bluetooth bridge to get the best of both worlds!

I think there is an option to select from multiple parameter sets using stick combos.

Gartenflieger

Why don't you try to contact the CRIUS guys to get the original firmware setup so you can verify your board isn't damaged. Nevertheless, of course the board should work with the current MWC software. Many people are running it successfully. So either the board is damaged or you messed up the config....

Yeah I have a similar one made by Odys. What will you be using on the MWC side for Wifi? P.S. I fully understand why you are doing this; Because you can! And it's fun! That's what we are here for, after all. Some time ago I started a UI for Android using the "App Inventor", but it became a...

Gartenflieger

Are you using one MWC for multiple models? Otherwise the rates are stored in the EEPROM of each controller, isn't it?

Are you going to link using Bluetooth or Wifi?

Excellent! I have been waiting for this. Thank you, EOSBandi! Upon startup, the wizard appears freezed. I found others have encountered the same problem before.

Yes indeed, as the MTK is a Drotek unit, I might actually get something sensible out of the vendor.

I can confirm

that uploading the 3329-1.9 FW into the 3339 will brick it _FOREVER_ .

P.S. Or maybe not so forever? If someone knows a way to reanimate it, let me know, I still have the brick lying around somewhere...

However, I've been struggling with what should be a very simple thing: installing the board oriented vertically. I have done just that a while ago with an EPP silhouette model. I stuck the package to the side of the model. Going by Alex's instructions for the sensor orientation it took (I think) ab...

Gartenflieger

Most people solve that by checking the soldering and all other connections. ( And maybe re-do properly some connections)

Gartenflieger

It looks like my numbers are going negative when they should be going positive. How do I adjust this in software? Thanks For each of the sensors: - First, make sure the right axis are used in the mix: when rolling the copter left and right, only the ROLL line goes up and down in the GUI. If the PIT...

Gartenflieger

Are you saying the problem might be within the GY_80 libs? Maybe, sometimes the sensor bobs are implemented based on visual inspection of the direction of placement of the individual sensors on the board. And for my own first selfmade bobs I found that error prone. So you should go through the prec...

Gartenflieger

Maybe you misunderstood the instructions:
MINTHROTTLE in the config.h is to be set high enough to make all motors spin up reliably when armed.

Minimum THROTTLE channel of the radio should read around 1000 in the GUI. Set min/max and D/R in your radio to obtain that.

Hi jerbs, immediate flipping is usually due to wrong sensor orientation and/or wrong motor connection and/or wrong motor direction of rotation. You might want to do a quick check holding the quad in your hand. Arm, spin up a little and if any of those bugs is present, the quad will try to turn aroun...

Gartenflieger

I would think in 1.3 there was no expo on throttle.
I think you are correct in saying it is an array. The array holds the R/C stick positions.

P.S: By the way, I think it is a great idea to have a simplistic version as a starting point for those interested in programming.

Gartenflieger

To me the rotation looks the same in both the GUI and the diagram for the "Quadricopter X".
Maybe you want to check once again?
