Moved to other topic my question ....

dramida

Me too, and it opens the door for auto-take-off and landing. It shoud be nice to have scriptable commands witch could be given from CLI, something like:

Code: Select all

Takeoff 10
Wait 5
Head 320
GoTo 120
While VBAT >14.6 do {crazy stuff :)}
RTH 30
LAND

dramida

Could you do an rushduino software version witch compile on an Atmega 16? (that would be compatible with remzibi hardware and many of us already have one )

dramida

Good finding Wilco! How do you fell about the rate of climb? I would prefer to have a wider range of climb rates.

dramida

Very interensting and useful application i found here I'll give it a try right now .................... I just tested your app on a Samsung Galaxy S III and most of the menus works, BUT, the most important, when entering in AUX or PID, the aplication does not shows the values, it shows 0 everywere i...

dramida

AP mode of altitude hold works very nice in Mahowik trunk(m). With a little tweaking, it could be a standard feature of MWC. Here is a demonstrative video in witch you may see the stick position and the altitude of the copter. An auto-landing attempt is also made successfully m I strongly advice you...

dramida

Hi, i just test-flight the quad with Mahowik branch MWC R1248 ( m) The focus was on controlling the altitude. config.h /* Natural alt change for rapid pilots. It's temporary switch OFF the althold when throttle stick is out of deadband defined with ALT_HOLD_THROTTLE_NEUTRAL_ZONE * but if it's commen...

I (http://fotografieaeriana.eu/index-en.html) want to donate an MWC UAV kit "UAV 433Mhz Autopilot GPS Flight Control System" (http://www.rctimer.com/index.php?gOo=go ... oductname= ) for each forum member who actively participate in GPS Waypoint Navigation software evolving.
Donations will be made gradually , accordingly to navigation software development.

dramida

What would improve to a copter this new routine? is it affected by lateral acceleration in angle computation? How fast is it compared with giro-acc CF?

dramida

An example of how Multiwii CAMSTAB works on roll-pitch axes i show here

Thanks everyone for supporting me.

dramida

Are you aware about ALT bug from R1188 afterwards? viewtopic.php?f=8&t=2678

dramida

Yesterday i re-tested R1232 on a totally different copter: Criuss AIOP with Ublox serial GPS in quad configuration. Altitude readings behave strangely, first it shows a high negative altitude (-26000 or so) witch is not so stable (worst than bmp085) and after a few minutes it freezes to 0 I am surpr...

dramida

I forgot to mention, as octo's are not quite common, the crius FC is configured in Octo flat plus. Does anyone have a working altitude on R1232 MWC? I need to hear some success stories

dramida

Immediately after software update to R1232, GUI showed on ALT graph -25000m or something like that and a wild baro graph with ups and downs, then i rebooted and worked nice for a while, i was impressed how smooth worked. In this period I observer that wen calibrating giro, the ALT graph had a sudden...

Nice board about MWC software undies

dramida

Using Crius AIOP with MS6511 baro on Mega 2560, Altitude graph shows strange negatives values some times or even flat after a while

Rolling back on previous MWC 1171 and everything works normal on the same controller.

dramida

Your programming work is sunken in hundreds of average posts, how can software pioneers could be more visible? I stumbled across your topic and i was stunned about what i found

I will certanly try it.

I tried to setup an NMEA GPS (Mediatek 3329) on serial 2 and in spite of all my efforts, the led does not flash (neither the GUI). Tested on 38400 baud, after re-flashing GPS with Eod Bandi recomanded 1.51 NMEA 5Hz firmware. Needless to say that GPS is working (tested with MiniGps 171 and OSD displa...

dramida

Let me tell you that i had the same gps pos hold bug with tricopter and also quadcopter ( i gathered a multiwii fleet here ) WInd is the incredient to test PH accuracy, because without wind, PH tests are pointless. Solution is simple and resembles with carefree mode : Rotate back correction vectors ...

dramida

Controlled rate of climb/dive by throttle Could you describe in details how you see this? More throttle (from point where althold was activated) => more climb vertical speed? As for me it works in my b2, b3... has some lag but good for smooth altitude tuning, i.e. not for rapid acro fliers Auto-lan...

...The wish of one person is not always the wish of the community. True. Someone should decide what features should be implemented in the name of the comunity. I think that person is you Alex. If someone gets rewarded for coding some features/ removing some bugs, is a win-win-win ( me -codder - the...

Thanks, you just got yourself 100 euro . Send me please your paypall account on PM, or even better, write it here, maybe someone else would appreciate your contribution . I hope this feature will evolve into MSP command. Add regarding logging in eeprom, for an end-user, all logs are not necesarry. A...

Here is how altitude holds in wind with MultiWii-R1177 http://www.youtube.com/watch?v=SB_O4swILJU

Thanks alot boys. Any news about baro- AccZ controlled climb/descent?

dramida

More and more voices are saying that 8 bit MCU are absolete. Please bring it to its knees and have a strong reason to step forward.

dramida

This is what i've done with multiwii last week.

http://www.fotografieaeriana.eu/panoram ... olare.html

I need a reliable platform and i am ready to support people who help me:)
Alex, I thank you for this wonderful project and the way you chosed to lead the way.

dramida

I prefer to sponsor new feature in multiwii than buy some other fancy controllers . I already did that twice for members of this community, privately. I encourage all interested folks to post here the prize for achieving different features of multiwii and multiply our financial efforts. It works lik...

dramida

Hi everybody, new here, first post. ..... I hope I missed something and someone discover a way to do that, actually I found impossible to compute a position for more than seconds with only IMU (no gps), Hi there Algorithmer, i am glad a new member joined our efforts to build a cheap open source pow...

dramida

Good move Mis. I'll test your new calibration routine. On what MWC release should i make changes? B3 from Mahowik or some main trunk dev? /Mihai Sebbi. I think, but not sure that altitude drop after switch althold on can be caused by 1G constants difference from real 1G reading. I make some code cha...

dramida

I think that calibrating at startup 1G acceleration is a must for successful repeatable behavior of all functions using accelerometer.(temperature variations, fabrications marginal errors, even altitude and latitude does count) Please consider a non leveled surface at startup.

dramida

Here you have a flight with more than 17 min of alt hold and pos hold flyin g with pushes up and down and sideways. I used Multiwii R1143 on Crius AIOP. m Thank you community for this achievement. I am looking forward to have an controlled ascend/descent with failsafe landing on baro and use of X-Y ...

dramida

I trully like it! i would try to build one for myself in a 50x50mm square PCB, where can i find some schematics?

dramida

No, because then you'd have to have the copter precisely level at power up. Good find about startup calibration on a non-level surface. Solution: We always can apply the per axis angle G corrections as we suppose that level is calibrated and copters stays still on ground. I am no more a software co...

dramida

1 Keeping track of each controller is difficult without an identifaction name/number. We need an editable field in gui in witch each board identifies itself. Ofcorse this field should be keeped in EEPROM and ideally not affected by software upgrades. 2 Keeping track of flight time would be nice. So ...

dramida

Can we just make an average of the acc values read at startup, when also giro is calibrated. And then define that average as 1g. G force differs from spot to spot, not much, but maybe enough to have signifficant drift in algorythm.

dramida

I found an European good source of GPS and fpv related gadgets here http://www.mr-lee-catcam.de/pe_cc_o3_en.htm

dramida

We need a startup calibration subroutine for 1g value.

dramida

I think we have a Bug in GPS. Try to yaw the copter in GPS pos hold and it will go all over the sky till you stop yaw-ing. Is this Bug enough? Sorry, but i cannot reproduce this. My copter stays within 2m with full yaw (if you like, until battery is empty). Maybe because I changed PH code. I am int...

dramida

Today i tested B2 version of Alex. 1- Can't use GPS based function as this dev version has no support for Ublox GPS 2- Altitude control (up and down) is to "soft" , i crashed into ground two times and it tends to lose altitude after a controled climb (verry slow). 0.5 m/s vertical speed is...

dramida

Hello Mr Remzibi, i salute your initiative.
As a 10 DOF Mega2560 board costs 63 usd ( http://www.rctimer.com/index.php?gOo=go ... oductname= ), i suggest firstly to write a serial OSD only for Mega Flight controllers. A further implementation should be i2C com for 328 FC.

dramida

For the past two months it seems that Mr. EosBandi has better things to do with his time

dramida

If bugs are cleared one after the other, there will be no magic after all. I had big ptoblems lately with ublox serial gps.

dramida

was this bug solved?

dramida

I made much more money by using Multiwii copters, take a look at http://www.fotografieaeriana.eu , you are not the only one whom i donated money. Actually you earned it. Please keep it.

dramida

Mahowik, you are the Man, i'll be the first who buys you lots of beer cans for your work. Even i didn't had time to test your last development Sw, I am convinced that we will reach a solution. 100$ from me, right now...donation is now complete

dramida

can't wait for this new ALT TO RTH function! ALT_TO_RTH already available in MultiWii_2_1_b1. You can download it here m sketch with ALT_TO_RTH_FINISH will be posted soon in MultiWii_2_1_b2 Autolanding will be possible only with sonar I think, because on altitudes less then 2m baro values become ve...

This mod should be included in shared trunk. It is about controlling tilt angle while stabilisation in enabled.
