MultiWii

Ziss, I have find 1 bug.... if I slowly decrease the input down to 900us (with servotester) The motor is making (little) sound (startup active?). If I decrease fast everything is shut down correctly. I use pwm_fast_100.inc and will you chance in Qynx20A.inc : #define DbgLEDOff sbi PORTD,2 #define Db...

I can import DXF autocad12, but located in the Netherlands....

epoxy milling?

Hello, The software is complete...... but not for Multiwii sorry, if there is interest I can fix it..... The PID tuning is only active when ik set the Tune bit (see picture) http://lynxshop.nl/product_images/uploaded_images/Mainscreen.png Normaly AUX1 is for switching LEVEL on/off and AUX2 for BARO ...

I use Ziegler–Nichols for PID calculation.... When I set the tune bit, I tune Gyro pid with AUX2 and level PID witch AUX1 Then With AUX3 I save the PID settings in EEprom. I tune the setting with the quadrocopter in my hand (Above my head)and feel the reaction. if(PMTR_Tune){ if(rcData[AUX3]>1700){ ...

Hi Everyone, What do you think, about releasing v 1.0 of FW? Any outstanding issues or missed/ignored suggestions left? regards, ziss_dm Zero problems after hours of flying I think its ready for V1.0....... I just finish the second version of the pcb. Pictures follow tommorow....... Ziss, Please se...

I did it already in my Gui... if there is interrest I put it in the Wii gui. http://lynxshop.nl/product_images/uploaded_images/Mainscreen.png Main screen http://lynxshop.nl/product_images/uploaded_images/flags.png Select PPM receiver if needed http://lynxshop.nl/product_images/uploaded_images/kanaal...

@all,

I'm looking for the Turnigy TY-P1 schematic...... (to find the hardware problem?)

thanks,


Rob

Ziss, - With 3 cels I don't have any problems.... Every combination have a nice startup and runs well. - As I understand the only problem is a unwanted reset? - if you want a hysteresis I can test it. - Maybe the problem is not the software but the hardware I'm going to read the previous posts and l...

@ Ziss, Great, now nothing have to be changed to test it.... Hi Rob, Would you be able to test this version (the support of the Qynx20A is included)? And also new ZC filter for Heiko. regards, ziss_dm Yes, I have test it.... I program with AVRStudio so I need to include: .include "m8def.inc&quo...

video of test with 100 steps resolution

After many flights today one of the test motor (the one with the bad bearings) burned out after landing , ESC was ok.

Hi Rob, You can try only one filter cap on the neutral point (MIDEN). regards, ziss_dm I have try but even a 1N capacitor is not working...... I have test version 4 and this is ok without caps works ok, smooth start, zero problems..... On the scope everyting looks good, nice spikes (not dirty) so i...

About your test fligh: Is it with standard RC range or with extended range? I have changed my software to extended for the test, but I think 100 steps is enough, if I can make some time I make a good test (outdoor with wind). The 3 10N caps in the feedback are placed extra for working with rev. 3 o...

Schematic Qynx ESC

original designed for pwm on positive site and RC_PWM on ICP input

The 3 10N caps in the feedback are placed extra for working with rev. 3 of Ziss dm version......

Maybe not needed in rev.4 , have to test this tomorrow.



Rob Keij

Test software rev3

ESC test, (with 10N caps added to the feedback)

@ziss_dm adding them, 1N to less (do nothing) 47N start OK but with high speed losing sinc. 10N ok, smooth start and current ok. try tomorrow the adjusted ZC filter, may be I can remove the caps..... this evening I post my schematic. For my quad board this ESC software works very well......... Rob

I have test the new software and I had also startup problems, but........
I have it fixed with 10N capacitors in the feedback.

I have fly with it and everyting looks ok.

Even with bad bearings(for test) Startup no problem and no smoking fet's


Rob

@ ziss_dm

Ok, I try this tomorrow. I test with "bad bearing motors" so the start up is not "clean" but it should work... and very good for testing

Rob

Hi Sorry for my english. Two weeks ago I reprogram my ESC (Mystery 12A blue series) with firmware from this topic. Quadro is now stable like never before. Thanks a lot for this soft But I have big problem. About 50% of crashes (three times) were ending with burned transistor (AO4409). The strange i...

sloppy.. no problem, my English is sloppy as well.. Ok switching to acro and then back to level resets the drift. that is not the Esc I have to think about this, its easyer if i can have the same problem but i dont have muliwii software board. I use my own board not compatible with ardueno or multiw...

Yes only by wobbles or short time drift....... If its uncontrollable Esc,s reacting not right to slow or wrong internal filtering. long time drift is controllable by the control sticks. and I think it should be the esc,s because thats the only difference. not everybody have this problem. you can tes...

@noctaro

if I read your post, ik think the problem is your ESC ,
if you decrease the P the problem is less but still there (try it)

Rob

@ tosjduenfs

I have test many ESC with my Qynx board (with 500Hz PWM) I had big problems with Multiplex ESC and castle creations.
I have discovered that the Multiplex Esc I have test are the same software as Castle Creations.

So you can be sure the problem is the Castle creations ESC's.

Rob

Yes you can, but not directly,
You still need a brushed controller. If the PWM output in the Multiwii software is modified you can drive
directly a Mosfet(s).

But its easiest to use brushed controler.

Rob

If PID settings are low I think the problem are the ESC´S.
(If frame is without vibrations)
what kind of ESC you use? (type and settings)

@ Berkely You also can try to look only after a High level I dont know wich pin you are using so you have to chance that. if(!(PINA&16)){// Only processing after a high level...... if(diff>5000) chan = 0; else { if(900<diff && diff<2200 && chan<8 ) rcValue[chan] = diff; chan++; i...

@shikra

Maybe vibration from frame to board?
Connect to GUI hold frame, power up en look to the screen......
