MultiWii

Arakon

First of all, are your FCs actually Arduino 2560? Which one are they exactly?
Bootloader should never be needed unless you actually flashed and messed up using the ISP port instead of FTDI.

Arakon

Did you calibrate the ACC? It will not arm until you calibrate.

Arakon

Did you select the correct board and chip in arduino?

Arakon

Did you calibrate the ESCs?
Also, while it's sitting on the ground, it's pretty normal that the motors don't spin up evenly.

Arakon

If the FC has a dedicated sat port, I'd assume it already has the regulator in place.
As for binding, the pins probably vary on a nanowii.

Arakon

//************************** // Defines that allow a "Bind" of a Spektrum or Compatible Remote Receiver (aka Satellite) via Configuration GUI. // Bind mode will be same as declared above, if your TX is capable. // Ground, Power, and Signal must come from three adjacent pins. // By default...

Arakon

I think he means dumping the FW that is currently flashed. That is possible through an external programmer, but only as a compiled binary dump, not as arduino code.

Arakon

Chances are that you didn't configure the GPS baud rate properly, or have it hooked to the wrong serial port.

Arakon

In the GUI, do all channels go from 1000 (low) to 2000 (high) and are centered at 1500?

Arakon

You should preferably use only the bec of one esc.

Arakon

Bluetooth does nothing but simply replace the serial connection. Instead of going to the USB converter, it goes to BT. Nothing is needed on the multiwii side.

Arakon

Did you stick foam on it? It has to be protected from propeller wash and bright light.

Arakon

If you are testing while it's sitting on the floor, it's normal that the motors don't spin the same.

Arakon

Crius AIO Pro v1 works for this.

Arakon

Supposedly pedestrial is meant to work best for our slow moving copters.

Arakon

Did you calibrate the ACC? You didn't calibrate your transmitter/stick travel, I see that much.
Also, can you actually arm the copter before you try to throttle up?

Arakon

Or the copter type was not set.

Arakon

"New" doesn't mean a thing, props are almost always unbalanced from factory. Prop balancing is one of the most important steps to getting a stable flight.

Arakon

It isn't, unfortunately. Multiwii stops at 8 channels total.

Arakon

You can simply get the current dev version, that's all stuff that will be included in 2.4.

Arakon

Technically, you don't need the display. Technically, you can experiment with your transmitter until you happen to find the settings that work. It just takes forever, and the display costs like 10 bucks off ebay. One thing you need to realize is that most companies that build and sell multiwii board...

Arakon

For the sat RX, you have to keep flashing back and forth (with the sat definition commented in/out), otherwise the sat rx data requests will interfere randomly with the reading and writing of values in multiwiiconf. To be sure the TX is set up right, you have to use an i2c display. I'm fairly sure t...

Arakon

Both are generic Neo-6 GPS modules, which is the same thing almost everyone uses. RTH as failsafe will only work if your receiver supports failsafe. That said, the flight controller in that set is quite outdated by now and GPS not fully supported on it anymore. Look for an atmega2560 based flight co...

Arakon

What you are describing IS altitude hold. The copter has no way of knowing if it is rising or sinking without a baro.

Arakon

Completely wrong forum for this. Megapirate has nothing to do with multiwii.

Arakon

Do you have a compass (HMC5883 or similar) installed? Without a compass, it won't know which direction it is facing.

Arakon

How much more rigid than aluminium do you want to get?
And for rigid, that is exactly the wrong way to go. The plastic arms amplify vibration and the dji clone arms are often so soft, you can easily bend them by hand.

Arakon

Pretty much, yes.

Arakon

That'll work, yes.

Arakon

First of all, your endpoints are not adjusted properly. They're not centered and don't go all the way up/down to 2000/1000. That'll instantly introduce a drift, when you try to lift off. If the motors start turning this late and this slow, you either have a crazy high throttle rate/throttle expo set...

Arakon

Whichever you define in #define RX_SERIAL_PORT x.
Remember that you need a signal inverter.

Arakon

Slightly over half? Then it should be taking off by itself.
Did you actually calibrate the ESCs? If not, run the calibration first.

Arakon

I'm running a mini tricopter. I finally got it to fly decently, but I have some issues with yaw still. The front props are counter rotating. When I turn left, it turns slower than right.. that's normal. However, if I turn only slightly left (i.e. just adjusting the "nose" a little to the l...

Arakon

And in case you still can't figure out how to wire it up, the Uno is basically the same as a pro mini, just 15x bigger and much, much heavier too.

Arakon

The one you linked is ages old and completely outdated. You can use your arduino, but it's much larger and heavier than neccessary.

Arakon

Considering that sensor board doesn't have a baro, it's perfectly normal that you can't get any altitude measurements.

Arakon

I just had a closer look at your USB adapter.. you didn't hook up the reset line (DTR), that is required for the flashing to work.

Arakon

You don't need to delete anything, you can just flash as is. I still don't see why it wouldn't work for you, as when I download that same firmware, extract the entire folder (not just the content) that is inside the zip, and run the .ino from inside that folder, it works instantly. Either something ...

Arakon

The end points are set up properly (although I did have to go up to 144% for throttle to reach 2000. Maybe some scaling would help? On the KK board, I only had to go to a max of 115% on any channel to hit 100% each direction). Telemetry switching is working with sat, so I can see the endpoints on th...

Arakon

I have a mini quad with MWii 2.3 (not sure about the exact revision, half a year old) on a selfbuilt Pro Mini based FC, which is using an Orange Spektrum satellite. Works absolutely great, up until you enter config mode for the OLED by stick combo. The stick combo works, the config menu is triggered...

Arakon

Like I already wrote above, copy the remaining files to that folder and you're good to go.

Arakon

When it moves the file to the new folder, did it move ALL the files in the folder, or only the .ino? If not all the files are in that folder, move them manually. Also, I just tried the file you linked. It's already in the proper folder, all you should have to do is double click it after extracting t...

Arakon

That usually means that you only have the .ino, but are missing all the other files. They should all together be in a folder with the same name as the .ino file.

Arakon

I just tried it on my broken board.. mag works, MPU/Baro don't, LEDs don't.. didn't try inputs.

Arakon

The sensors are the basic set you'll find on i.e. the crius aio pro.. HMC5883L, MS5611 baro, MPU is a 6000 instead of 6050, but as far as I am aware, should function just the same. I'm guessing you'll have to do something about the Atmega32u2, which does the PPM encoding as well as USB/serial conver...

Arakon

Well yeah, I am talking about the "old" sensors of course.

Arakon

One option is to simply desolder/cut off the mag and baro. That way there will be no device conflict. Best done with a hot air station or very carefully with a scalpel.

Arakon

You can not flash over telemetry link, you have to connect it via USB.
In arduino, when you downloaded the whole multiwii firmware package, you open the multiwii.ino by doubleclicking it.

Arakon

1 serial port only on the 328p. The I2C board has absolutely nothing to do with the mag, those combo boards just have the mag stuck onto the same board as the GPS, but technically, they're entirely seperate units.

Arakon

I'm no coder at all, so take this as just a theory and I have no idea how difficult this would be. Wouldn't it make more sense to change the compass calibration to run until a certain amount of samples of all directions is collected? Rather than 30 seconds and praying that you got all directions pro...
