It works fine for me.
After the acc-calibration i need 2 trimsteps with the sticks to get it perfect.

Be shure to follow this stages.

I tested this mod to day. Managed to fly a full acc in stable mode for the first time ever. I will set up and test the difference and make it possible to switch between the modes in flight. #ifdef LEVEL_PDF if(AUX2>1700){ PTerm = -(int32_t)angle[axis]*P8[PIDLEVEL]/100 ;} // The orignal way else{ PTe...

It works fine for me... And together with Shikra's Driftkiller it's the first time i'we been able to fly a full battery in Stable mode... I can confirm the procedure. First set a ArmBox in the gui. http://dl.dropbox.com/u/9750287/MultiWii/sshot-3.png Do the stickcommand. http://dl.dropbox.com/u/9886...

With the last changes on the 1.9 code.
My NB stops working after a couple of seconds.
The wmp contiues normally.

If i press reset it works 2-3 sec again then acc freezes.
1.9 ver before last changes works but cyckletime flickers between 4900 to 5100.
Used to be 6000 before.

PatrikE

It's not so much the cold tempertue who limits the flying.
The worst issue is the short day's.
It starts to get dark between 3-4 in the "evenings" during the winter..(If the weather is clear)

You can find my small project here.

Verified as working Cameras:
Sony NEX.
Canon 550D.

The other Cameras need to be tested..

Looks really god

The PassthruMode is nice to use for initial flights.
Launch with Passthru and switch over at safe altitude.

Hi DinoBravo. What kind of plane are you setting up? I'we done some test with a Funfly model. I have a couple of questions : 1) Why does the ACC light not turn green (directly below the NUNCHUK)? 2) When I deactivate LEVEL the gyros don't correct the ailerons or elevator - is this normal or is this ...

I have been skimming the net finding ir codes for cameras. When i run the code as a standalone triggerdevice I can get it to work on the cameras in the house. A Sony NEX5 and a Canon 550D. The problem is that the triggertimes is around 10 cykles of the MWii code. The timing in the triggercodes is ha...

2S vs 3S...

With 2S the throttle position for hovering will be close to full throw.
With 3S the throttle position for hovering will be around midstick.

2S will give wery little spare power to compensation.

/Patrik

PatrikE

Probobly the gyro or acc values isn't 0 and the controller starts to compensate for that.

My mixtable looks like this at the moment. #ifdef VTAIL4 motor[0] = PIDMIX(+0, +1, -1); //REAR_R motor[1] = PIDMIX(-1, -1, +4/10); //FRONT_R motor[2] = PIDMIX(+0,+ 1, +1); //REAR_L motor[3] = PIDMIX(+1, -1, -4/10); //FRONT_L #endif http://www.multiwii.com/forum/viewtopic.php?f=8&t=665&p=4204...

Yuo have probably checked that the real serial stream comtains what you expect...
But thats my only id'e right now

It would be handy to show TRIM values in GUI (like how many clicks there are in each dir) Try to send it as debug values...

All yuo need is actually co paste 3 rows in the serial section. then you can reset PID's from Arduino. case 'R': // Clear EEprom to reset default settinga next start. for (int i = 0; i < 512; i++){EEPROM.write(i, 0);} break; The Gui implementation is more work to update every time. We can place it o...

I think one problem is that Failsafe is overwriting your serial commands.
So start with to first comment this line in config.

Code: Select all

#define FAILSAFE             // Alex: comment this line if you want to deactivate the failsafe function

I use this code from a old thread to restore defaults.

Just send "R" to arduino with Serial monitor or Putty.

I have also added a reset button to my gui.

I wote for copterrichie... Start with a basic setup untill you have a perfectly working machine. It will not fly by it self and and need a bit adjusting before you have everything perfect.

For duemilanove you should go with #define PROMINI
The pinouts is the same.

Made a new check and it shows 0 degrees when heading north.

Do this check.
http://www.multiwii.com/faq#How_should_be_the_sensor_axis_directions
Mag and Acc should move in same directions.

PatrikE

@Alex
The mag orientation ogf the mag on this board should be.

Code: Select all

  #define MAG_ORIENTATION(X, Y, Z)  {magADC[ROLL]  = -X; magADC[PITCH]  = -Y; magADC[YAW]  = -Z;}

All axis inverted.
The other sensors is correct.
Tested and verified.

You have the WMP upside down in the picture.
But this is how it should be conected seen from bottom side.
*|VCC|SCL|*|*|SDA|GND|GND

PatrikE

The Mega boards is using.
PIN 20 + 21 (SDA + SCL)
And Pin 37 as powerpin.

I Have around 6000 with Wmp & NB.

You also need to replace the rxtxserial.dll file in the Multiwiidev filder to.

Make sure everything is connected the right way. Bad soldering on pic but it's a god illustration from http://www.multiwii.com/connecting-elements http://radio-commande.com/wp-content/gallery/triwiicopter/img_0420.jpg In my WM+ setup with i use pullups and 100khz. #define I2C_SPEED 100000L //100kHz ...

It sounds like you have some mix active in your TX.
Or most likely you run it in heli or glidermode.
set it in acro mode and delete all existing mixes and start from fresh.

/Patrik

PatrikE

In multiwii_dev_ file

Code: Select all

// ******************
// rc functions

#define MINCHECK 1100
#define MAXCHECK 1900

PatrikE

Normally the radio is to be set in airplane mode.
If you set it in heli mode its possible to use throttlecurves like on helicopters.

PatrikE

I think it looks like senors isn't oriented in the correct direction. Or engines connected on wrong outputs. It sure seems like it's compensating in the wrong directions. Check the gui to se how the engines compensates. if thats ok the esc's is probably conneted to wrong outputs. Hold it in your han...

I tested V1107.
All tendens to flipp id gone now..
Flies nearly perfect.

Loaded V1108.
The gyro is less sensitive. Reqire much higher PIDvalues.
No more daylight.
No more testing to day.

PatrikE

Use Winmerge.
http://winmerge.org/

You can compare 2 folders and stich them together.

PatrikE

Test if the old ver still works...
To eliminate hardware errors.

PatrikE

After upgrading to a new version you must recalibrate the ACC.

PatrikE

I tested on a funflymodel once and there is a lot of adjusting on the PID.s
It overcompensated massively.
P must be lowered quite much.
I plan to test on my EZ Hawk but haven't done it yet.

PatrikE

Iw'e seen some strange tendency on my machines to. When flying in acro mode just hovering around there is no problem.. But in acro mode flying Fastforward and some harder banking it will start to drift after leveling out. It feels like the gyro looses zero... First time was scary I had to hold Pitch...

PatrikE

It seems like one of the sensors is wrong.. Both should go in same direction when youre moving it. If you monted F.ex gyro upside down you will get that effect. This is the correct orientation of the Wii sensors. http://radio-commande.com/wp-content/uploads/2010/06/WMP_NK_wiring1.jpg /Patrik

PatrikE

If a baro is used one can use it to do a controlled decent.
like Althold just lower the altitude to hold by 5cm/sec or something.

PatrikE

Have you changed Maxthrottle?
It should be around 1850.

Check the throttlevalues in the GUI to see if it delivers correct to the Esc's

PatrikE

I run my with this mix. #ifdef VTAIL4 motor[0] = PIDMIX(+0,+1, -1); //REAR_R motor[1] = PIDMIX(-1, -1, +4/10); //FRONT_R motor[2] = PIDMIX(+0,+1, +1); //REAR_L motor[3] = PIDMIX(+1, -1, -4/10); //FRONT_L #endif Added 50% pitch on front motors. When i pull full YAW it will drop inner front a little. ...

Ahh Be safe fly low and slow...

Just the guys with hockeysticks missing.

PatrikE

I can't find any information on them saying they have PPM out...
But if it's true then it's a SUUUPER deal.

PatrikE

I'm planning the same.

It's possible you have to change the mix a little.
Check out this thread.
http://www.multiwii.com/forum/viewtopic.php?f=12&t=688
It explains how the mixing is done.
