MultiWii

Arakon

That's pretty much exactly why.. you have to adjust your PIDs to work for all components of the copter.. if you make a major change, you have to re-adjust your PIDs.

Arakon

You can't define the board and then seperate sensors on top of that. Why are you using Multiwii 2.1? In 2.3, I get: //#define CRIUS_LITE // Crius MultiWii Lite //#define CRIUS_SE // Crius MultiWii SE //#define CRIUS_SE_v2_0 // Crius MultiWii SE 2.0 with MPU6050, HMC5883 and BMP085 You can try #defin...

Your bootloader may have gotten corrupted for some reason.
You could try using an USB to serial cable (cp2102 or FTDI based) and connect that to the ftdi port to see if you get a connection this way, to make sure it's not the USB port or chipset that has been damaged.

Arakon

Considering I managed to figure it out myself by trying things out and reading through the forums, it is nice to have confirmation of my findings. Are you going to spam all threads now because noone helped you within a few hours with a totally obscure issue that you likely caused yourself? I'm going...

Arakon

In Arduino, set the board to pro mini.
Check in the config.h if you chose the correct board.
If the board is right and you keep getting i2c errors, chances are that you have a defective board.

Arakon

Why are you using 2.1 in the first place? 2.3 is current. You will have to re-set everything, i.e. aux assignments, likely channel endpoints and mids (on your transmitter), and will have to calibrate the ACC and mag again before they work right.

Arakon

Aside from the fact that you were more rambling than giving detailed information, you have a fucked up windows and/or laptop and you try to blame multiwii for that? NOTHING multiwii does can mess up your PC. The USB chipsets are generics that are used in thousands of other applications. Not to menti...

Arakon

Uncomment #define motor_stop. It's perfectly normal otherwise.

Arakon

I'm using a Walkera Devo 7E with deviation firmware. I only had a chance so far to do a brief test and calibration flight in the (very small) garden, thanks to the weather here, but that worked without issues.

Arakon

There seems to be a bug with the heading reading of the android phone as of 2 or 3 versions ago. When I go to the GPS info screen, the android heading always shows around 170° for me, and if I turn the phone, at most the heading changes by 10-15° in either direction, then returns to approx. 170°. If...

Arakon

Your power wiring is creating a magnetic field that changes the more you throttle up. You have to move the magnetometer out of range of that field.. i.e. move the FC higher up or use an external magnetometer and put that somewhere out of the way.

Arakon

Is there any means to add more aux channels to multiwii? My SBUS receiver supports 14 channels, my radio 12 channels.. however, I can at most use 8. My radio also can not support more than 2 3-way and 2 2-way switches, so extended aux states are no help here.. I can use the trim buttons for addition...

Arakon

This doesn't seem to work. I get no compilation errors, but also no function.. even though multiwii wingui displays Aux 5&6 as working and switching properly.
Edit: Works now. #define DISABLE_SERVOS_WHEN_UNARMED had to be commented out. Thanks!

Arakon

Nevermind, I'm an idiot. I had (in my head) numbered the serial plug the other way around, so what I thought is RX3, is in fact RX1.

Arakon

I received an OrangeRX 3 Channel SBUS Receiver today (SBUS supports 14 channels). When I connect to to RX3 on my CRIUS AIOP 1.1, it usually doesn't show any signal in multiwiiconf (all channels set to 1502 and not moving). When I move the sticks around some, eventually it will react.. by changing al...

Arakon

Yes, that should work.

Arakon

That will work, yeah.

Arakon

The chipset is outdated on that one, and so is the baro. If you are getting a new FC, get an atmega2560 based one, i.e. the crius all in one pro. You could use the rest of the stuff that comes in that package, but it's probably cheaper to buy them seperately.

Arakon

Do the servo ports you are using have power?

Arakon

Those won't activate unless you have a proper GPS lock and are armed.

Arakon

Get an I2C converter board for the GPS, then you can use GPS while still having the serial port free.

Arakon

Did you cross RX and TX? RX on the ftdi board has to connect to TX on the controller, and vice versa.

Arakon

You can't, correct. Your best option is to get a controller with an Atmega 2560, that one got 4 serial ports.
You'd have to keep switching around otherwise, since you can not connect to PC while GPS or sat is hooked up.

Arakon

1) The Phantom FC has GPS. Some drift is normal without GPS hold. 2) Look at the deadband option in config.h. 3) Wrong FC, basically. For "as stable as possible" you'll need GPS and a FC with current sensors (the baro on the SE is outdated). If you have the cash and don't want to fly, but ...

m this one, actually. I used the L-arm (make sure to use the right one for your motors, I used m, for these you need to use the HK2206 L-arm) and the Mobius mount, and arm3_final from this one m to mount the gimbal to m with zip ties and servo tape. Total gimbal weight with camera and electronics is...

I use a 2D gimbal that basically consists of 3 3D-printed L-shaped strips, 2 cheap motors from HK and a cheap chinese controller. m That was my very first gimbal test flight with the mobius.. starting at 1:50, I flew some turns and did some quick direction changes to see how the gimbal holds up. The...

I got an sbus receiver on the way (OrangeRX DSMX 3Ch + 14ch SBUS). I tried finding info on how to hook it up and configure it, but there's basically no info except for discussions about the protocol. What I'd like to know: 1) config.h states "The following line apply only for Futaba S-Bus Recei...

Arakon

Arakon, maybe your EEPROM is corrupt. Please clear EEPROM and try again. Did that just now, will try once it stops storming here. Edit: Is there any way to save the mag and acc calibration values to PC? ACC calibration is done quickly, but mag usually takes me 2-3 tries and isn't exactly easy with ...

Arakon

Different motor speed is perfectly normal while it is sitting on the ground. Check that you didn't mix up any motor connections.

I noticed some issues with nav beta 7 and a crius aio pro 1.1, external mag, neo-6m GPS. Even with 8 satellites, when using mission mode (drawing waypoints with multiwii ez gui) or RTH, the copter will often either overshoot badly (I almost always have to abort RTH because it would just fly past me...

Arakon

Are your transmitter center values exactly at 1500? If they are not, that will be why.

Bluetooth range on a cell phone usually drops out after 20 meters or so. I definitely recommend buying a proper transmitter.

Arakon

Awesome, I'll give that a try as soon as the receiver arrives here.. unfortunately, it's still on the way.
And yes, the standard PWM outputs are supposed to work, but they're on channels 1, 2 and 3 unfortunately, not added to the end.

Arakon

You can't measure voltage on PWM pins. That's a signal that is rapidly moving up and down, whatever voltage you measure is garbage. It sounds more like you didn't calibrate the ESCs.

Arakon

I'm trying to set up an sbus receiver (OrangeRX DSMX3, 3 normal channels, 1 14 channel sbus output) to also handle things like a video switcher (uses pwm signals to determine camera 1, 2 or 3 for high/mid/low), and camera gimbal pitch (setting gimbal to point downwards, angled or straight forward). ...

Arakon

Props look good, but 2S really won't get you off the ground with 930kv motors.. they just won't spin fast enough. Make sure the motors spin in the right direction.. i.e. in the direction of the blunt, higher edge of the props. The transmitter should be able to do what is needed according its descrip...

Arakon

"R" stands for right hand rotation. Make sure you actually have the right props, otherwise the setup should be fine.

Arakon

I had that too, but the other way around, when I didn't erase the eeprom before going to a different software. Run the eeprom clear sketch, then flash the software, then upload the font files.

Arakon

You don't. The servo is physically limited to 90°, if you want more, you'll need to buy a special servo.

Arakon

You need just one I2C adapter board. You just hook both devices to the same pins, I2C devices use different addresses to know which one is being accessed.
That GPS you linked to does not have the compass. This one does: http://www.banggood.com/Ublox-NEO-6M-GP ... 28633.html

Arakon

I2C can handle several devices.. and yes, you absolutely need a compass.
If you want to stick with that flight controller, get the I2C GPS adapter.

Arakon

One small bug to report: When putting the GPS coordinates at the top, they're cut off (PAL mode), you just barely see the bottom lines of the text. When setting them to bottom, the callsign is in the same line and is being overlapped by the coordinates.

Arakon

You can actually record and use the live-out at the same time.. however, be aware that the live-out has a lag of approx. 100ms, so you may not want to use that camera for highspeed racing between trees.

Arakon

No failsafe by default.
The motors don't simply turn off. Unless someone happens to find it, your chances are very slim.. just pray that you won't read in the newspaper tomorrow that some kid was killed by a quadcopter dropping from the sky two towns over.

Arakon

That's a voltage regulator. If that overheats, you either mixed up the + and - lines or the GPS is drawing too much power.
If you still get errors now, with the GPS removed, chances are that you fried something on your flight controller.
