I have a model glider and I need to record the motion of it

Do you want to just record the datas in some media OR you want real time recording/displaying the readings.
I'm asking because are two totally different options .

NikTheGreek

Just an idea that came to my mind.

Do you think that the GPS FIX problem is a result of the resonators i'm using in both boards ? (I2C GPS board & the FC)

Thank you for your answer.
swapped tx/rx cables but now i don't take any signal.
My problem is that the GPS FIX isn't stable.

NikTheGreek

Thank you vistauser for your answer.

But my problem persists even with your suggested settings.
As i mention here viewtopic.php?f=8&t=649&start=1440#p25562 .
I dont know if it is a GUI problem or anything else .

Hi. three days ago successfully flashed my SKYLAB SKM53 based in 3329 module with new firmware (more details here http://www.multiwii.com/forum/viewtopic.php?f=16&t=2639 ) The problem i'm facing is that i get no stable GPS FIX. The data displayed at the GUI correctly Lat - Lon..etc.. even if i h...

No one ?

Acording to the EosBandi "manual" .. The GPS implementation in MultiWii (both I2c and serial) expects that your GPS receiver is 1. set to 10Hz (or 5Hz) update rate 2. communicates at 115200 baud speed 3. and output GGA, GSA and RMC frames This values must be set to 10 in each dropdown menu...

Use the calculator form here.. http://panoramaic.se/configurator/dev_20120414/
no matter what values , will give you the results.

Good job
Looking good....

As i wrote above successfully flashed my SKYLAB SKM53 and is used in I2C mode (additional arduino 328p). What i've done so far is... 1.Uploaded I2C_GPS_NAV V2.1 to my secondary arduino. I didnt made no changes to the file 2. In the Multiwii_2_1 in config.h a. uncomment #define I2C_GPS b. defined the...

Hi. Successfully flashed my Skylab SKM53 according the directions found here m Everything during the flash went as expected..BUT when i'm trying to test my GPS using Minigps found in the in the above link seems that is not working. In the program i select the com port and boudrate and then "COL...

NikTheGreek

I had this "crazy" idea.

"Home base" tracker on the quad/plane to move the antenna accordingly
combined with a base tracker that will follow the plane/quad movements.

I dont know if this is posible but i think that will be usefull for many users.

NikTheGreek

Hi. I've read a lot of post concerning the SKYLAB SKM53 GPS that i'm holding in my hand but i haven't taken a clear answer . This module it is or not compatible with MW ? If yes could you please provide me with a link on how to do it ? If no ... could you please help me to buy a new one that is comp...

Hi, since i like to build my one boards i wonder which solution you think is better at this point of development of MW and of caurse for future use ? 1. A board based Atmega 2560 like this m 2. A board based on STM32 like this one m Please help me choose the best option or if you have a better solut...

Have you test this ?

Hi.
I wonder if and how i can build a diy antenna tracker that will work with multiwii code.
What i found so far is http://www.rcgroups.com/forums/showthread.php?t=1651310
Any available link will be much appreciated.

You are right...somehow you have to connect the ISP to the microcontroler directly

NikTheGreek

2nd attempt.

Take off with default PID
ACC enabled since the begining and at 46 sec BARO and MAG enabled...but then tilting slightly front.

What i must do in order to make my Quad more stable even without ACC , BARO and MAG ?

i was facing similar problem and the problem was my ESC.
Somehow and without reason the aluminium plate made contact with the componets of the ESC and created a short cirquit.

NikTheGreek

Im using this all the time

What realy save me is the DEADBAND...
i put it to 10 and is much better..probably i can set it to 8 with a litle more effort.
BTW..yesterday i had my first "flight"...[url]http://www.multiwii.com/forum/viewtopic.php?f=9&t=2477

Thank you guys for your words.

The best is that right after the crash my Quad had only some aluminium parts of the landing skid bended !!!
Apart my pride , everything is OK

NikTheGreek

Hi
This is my home made Quad.

And here is my first attempt to fly.

https://www.youtube.com/watch?v=VeZj3gBJvGo

The truth is that i got no experience in flying rc planes or quads.
The last time i flown something was a KITE !!!!

NikTheGreek

Finally , seems that i discovered what is the problem.(i'm not sure) Yes the #define DEADBAND options when used is giving a solution but in fact we cover the problem under the carpet. The problem is there and is nothing else than bad aligned sensors. I discover this the hard way..three days now. The...

NikTheGreek

one more thing besides trimming min-mid-max you must set #define DEADBAND 6 in your config.h. the value is based on how much your sticks fluctuate from 1500 when it is at midpoint. I had to set mine to 24, and the motor speeds are now super stable. Seems that #DEFINE DEADBAND is doin the job !!! im...

NikTheGreek

Some of us we are facing problem to align all motors to the same power level during the setup.

so i think that it would be great , if it's possible , to make an "auto level motor function" !!!

NikTheGreek

One more thing you can try. Load the latest "shared" code from trunk. You have to do an SVN checkout of trunk branch to get the file. Then add the multiwii shared folder into your arduino sketch folder and rename the multiwii_shared folder to just multiwii and load that to your flight con...

NikTheGreek

I'm about to explode !!!! I've followed all your valuable advices , and thank you very much for your effort and time. What i've seen is that what ever i do the motors align for 2-3 seconds and gradually the Rear_L is decreased and the REAR_R increased !!!! I dont know what else i could do .

NikTheGreek

Can you provide us a pic of those "crazy readings" !!

http://m.youtube.com/#/watch?v=knagzCgXGEg&desktop_uri=%2Fwatch%3Fv%3DknagzCgXGEg Thank you but....nothing If you can see difference in GUI and noticed it in flight (like in your case) I suggest that you clear EEPROM (Arduino > File > Examples >EEPROM > eeprom_clear) and than upload correspondi...

NikTheGreek

and how do you explain the fact that the problem remains at the same motor even when i switch places in motors and escs ?

NikTheGreek

NikTheGreek

Thank you TS00

NikTheGreek

One more test.
I replaced the "broken" ESC-Motor pair with a different one and the problem remains as it was, even when i switch the "broken" with one of the other three the problem persists in the READ_L in the GUI !!!!

I'm confused !!!!

HELP !!!!

NikTheGreek

I made a test by switching places of the back motors.
Back_L <-----> Back_R
What i saw was exactly the same as previus tests(Back_L lower)
which means...
a.my TX is creating the problem ?
b. it is a software problem ?

am i wrong ?

NikTheGreek

My English are poor so i'll try to "decode" ... IN VER 2.1 You can trim that out by using the trim switches on the Tx but only in gyro mode, that is level mode not switched on. 1.You mean in PASSTHROU MODE right ? You can get it flying hands off in this state then you can set about trimmin...

NikTheGreek

Hi again. As you can see the REAR_L motor have less power than the others. Calibrating my quad seems that it doesnt effect the motor power. In my first test flight my Quad lift of the ground but tilting left and back. Is it a motor problem or software ? http://i47.tinypic.com/sdgpjd.jpg

NikTheGreek

Seems that this is my last question before my first attempt to fly my quad. So i have a last question for you. Do you think that is better to ground the ESCs GND (black cable) in my aluminium frame OR NO ? Of course i'll ground also my battery's negative to the frame and all electronic parts. This w...
