MultiWii

Found the problem. Used MultiWii WinGUI without v2.3 support. When you write any value with it, it changes some values at places you don't know about. My bad

I cannot understand this... I take a fresh mw build and only make these changes: #define TRI #define MINCOMMAND 900 #define I2C_SPEED 400000L #define CRIUS_AIO_PRO_V1 #define SERIAL_SUM_PPM #define PPM_ON_THROTTLE And the problem described above still persists. Arrgghh... Like it's a hardware proble...

No. You uncommented: /******** special ESC with extended range [0-2000] microseconds ********************/ /**************************************************************************************/ //#define EXT_MOTOR_RANGE // using this with wii-esc requires to change MINCOMMAND to 1008 for promini ...

This problem went away. I think it was when I commented out #define MEGA_HW_PWM_SERVOS

Hi, I have a problem with my tricopter, it's running on a crius aio pro v.1. When disarmed, the motor outputs shows 900, which is my MINCOMMAND. But when I arm the tricopter, the motor outputs goes to 1 increases with throttle. When throttle is around 1500 the motor outputs have reached 1000 and spi...

At least for arming and calibrating IMU you can either see the LEDs flash or you can see the copter is armed in the PC software,

Hi, don't know if this is common, but I have to start both MultiWii Conf and WinGUI in Windows XP compatibility mode to make them run. WinGUI wouldnt't start at all. After running in XP comp. mode I even notice some strange things like settings won't stick before I've tried a few times. Don't know w...

Hi, It's been a while since I've flown a multiwii setup, now flying arducopter, but want to install mw on an "acro-quad". I think acro mode in arducopter felt funny. When yawing you rotate the multirotor around it's own vertical axis. Which, when in a roll or pitch, is not vertical. When i...

Hi, I'm designing my own tri-frame and am making it from PCB material. So I can make solder pads for battery, ESC, LEDs and so on. But it would be very cool to implement a complete multiwii layout so my customers can choose to buy as a kit or fully assembled. Or just the PCB and mount your own fligh...

Thanks PatrikE. I discovered I didn't have the problems with ESC beeping while also connected to usb, hmm... So I noticed I didn't have power to the board when only powered with BEC Problem was, the 5v jumper from BEC to mcu and everything else was torn and destroyed. My 4-in-1 ESC had smashed it. T...

I scoped the motor PWM outputs in all I see is "rubbish", see attached photo. Never mind what I just wrote about the "rubbish". Seemed I couldn't use the microusb connector as ground, so when I grounded the probe properly the signals shows as plain 0v, no pulses. Does the v2.3 d...

Some good and some bad news. It seems multiwiiconf is not able to display values lower than 1000 on the motor output, because I double checked in WinGUI now and it showed 950 on motor outputs as expected from MINCOMMAND parameter. Now, I then went and checked what was bothering my ESC (hobbywing 4-i...

I've had this problem before, don't know how I've bypassed it earlier though. I have changed MINCOMMAND from 1000 to 950 to 900, but nothing is changed when i look in the GUI, still shows 1000 when unarmed. I have tried clearing eeprom with the eeprom clear-sketch and everything. EDIT: By the way th...

Hobby developer here. And I keep asking myself, why I still have to do some basic settings like min/max throttle value in config, I think this would be better off i GUI as it's a pain to tweak config.h values while out flying. and what about "GUI globalsettings pane" ? Yes, I did a search...

Yes as long as it functions like a regular Android tablet/phone and has bluetooth, yes. You need to have access to google play or download the .apk (android program file) for EZ-Gui from somewhere else.

Can anyone be so kind and observe the YAW values of the magnetometer, and post here about it?

What I'm suspecting is that since I'm far north (Norway) it's mostly the pitch and roll values that complete to the total YAW value? But I really have no clue.

Did you resolve this issue?

Did you find a solution to this?

You were right, my house sunk into the ground the day after.

Thanks Luis, I can see I have too much noise, the ROLL looks worst. I have tried balancing my props, my frame is a F450 flamewheel clone and I've lowered the low pass filtering on the MPU6050 down two notches to 98Hz, but I know this is not the way to kil noise induced by mechanics. About your video...

Hi,
Can you look at the picture and tell me if the vibrations are bad? I have balanced all four props, and motors are running at 1300, close to take-off.

Hi, first I had a multiwii standard fc (mega328p) but I lost the whole quad and bought a second one with bigger and better Crius All-In-One V1.1 (mega2560) fc. Same issue on both, if it is an issue... The YAW value under magnetometer only differs between 160-180 degrees. Sometimes it's all the way d...

I think you're right. I have found out that re-calibrating ACC (unarmed) when the copter is bad doesn't fix anything, it still re-calibrates at around 7 degrees. But when I calibrate the gyro it usually works! So it seems my gyro ITG3205 can be smacked out of calibration at crashes.

rascal329, you're might referring to oxnard28's problem, who is not the author of the thread. The problem was solved in post # which I can't find... Two posts above yours.

You should try //#define MICROWII // MicroWii 10DOF with ATmega32u4, MPU6050, HMC5883L, MS561101BA from http://flyduino.net/

The hobbyking also sells this board as MicroWii so it should be obvious

How are your sticks? Can you properly put throttle at min and yaw at max? You should see it in the gui.

Hi, Sorry for all the posts here, but I'm getting closer to my problems. When I power the multiwii via ftdi cable and watch in multiwiiconf I can see the roll axis starts to drift from the beginning, and it ends up at about -16 degrees. If I press calibrate, it "wobbles" a bit and settles ...

scrat, I did, I've been flying (uncontrollably) ever since

Hi,
after almost every second crash landing I have to re-calibrate my multiwii se. I guess this has something to do with my stick combinations while tackling the landing. Is there a way to turn off stick acc calibration by stick combos while multiwii is armed?

Thanks,
Henrik

Hi,
In the BMA180 datasheet it says it's been extensively calibrated in the factory production line. Can I somehow set my ACC calibration values to 0, so I only use the factory calibration?

Henrik

Just experienced the same problem. It's the failsafe kicking in when PPM level on thottle is too low from the receiver. It makes the multiwii have a hickup and you see angle-modes goes active, like you'd expect when failsafe kicks in. Thanks, great help everyone.
