Wait for Mollie air-plane mode clip, Copterichie!

Hi Dramida, if you meant RX failsafe, you can disable Frsky RX failsafe by rebinding the receiver (from frsky user guide).

vpb

Hi, have you checked the correct ESC pins connection? Do you use CCW + CW props and are they mounted in the right direction?

Look at that http://www.multiwii.com/connecting-elements (Atmega328 or MEGA).

vpb

Hi PatrikE, very happy to see that you still take focus on airplane mode, cause I have a spare Crius SE and want to use it in my FPV plane. Does it warm up? and have you tested the new AIRPLANE RTH yet?

vpb

latest development version

http://multiwii.googlecode.com/svn/trun ... wii_shared

or you can checkout any version
svn co http://multiwii.googlecode.com/svn/trun ... wii_shared -r xxxx

vpb

It depends on Alex and others developers, some features are stable enough, they should be closed and packaged into a released version. Nothing should be waited. And the latest development version is always usable & stable. You can check the development log at m, with some developer's description...

Hi Dramida, the vario altitude looks promising, but do you feel sometime it's not continuos, especially in height gaining. But overall it's still very nice, I'll merge back the vario altitude with latest dev.

vpb

I'm on Turnigy 9X, Frsky + Er9x, but I made switchable RF module, and the stock RF module and 6 other turnigy RX are all still usable . About Failsafe, just curious, anyone here use Frsky failsafe instead of MW code. With Frsky RX failsafe the RX applies all saved channel's states, so we can easily ...

Another nice clip! Hi, you use gopro as the FPV camera also? Which lense do you use? It looks like the depth is real.

vpb

Max value (I refer on frsky display lcd) is 10 characters including the period. I dont think we need GPS_distanceToHome, GPS_directionToHome with LCD mounted on the flying machine. But if it can transfer wirelessly to ground (bluetooth), it'll be nice. In that case, I think you can consider show the...

vpb

ok. How many digits would you like to see for each? Less is better wrt. both computation time and readability. Sth like this will be nice, but ofcourse it depends on LCD characters limit E10668.4004 N1071.5075 Datas_Longitude_bp = abs(GPS_coord[LON]) / 100000; Datas_Longitude_ap = abs((GPS_coord[LO...

vpb

HI Hamburger, according to frskytelemetry GPS data: Datas_Longitude_bp = abs(GPS_coord[LON]) / 100000; //before period character Datas_Longitude_ap = abs((GPS_coord[LON])/10) % 10000; //after period character Datas_Latitude_bp = abs(GPS_coord[LAT]) / 100000; Datas_Latitude_ap = abs((GPS_coord[LAT])/...

vpb

Hi Hamburger, GPS coordinate, number of satellite will be nice.

v2.2 - Christmas's gift for multiwii community, can it be?

vpb

Hi EOSBandi, I see your new commit on latest r1284 dev. "No changes in the mag calibration dance, gain calibration is done automatically
at every startup". I want to test that new MAG calibration code, does the procedure change?

Thank you!

Thank for your info!

thank you very much timecop! I'll try your code and update some result here.

Hi, has someone attempted to integrate Frsky FAS-100 to Multiwii board? I've seen Hamburger wiki post about hardware sensor integration, about mapping sensor data input to arduino value [0:5v] -> [0:1023], and a DIY Frsky I2C bridge of mr.rc-cam but not documented yet. Many people here use Frsky and...

vpb

haha, good foot

. Is your rx a frsky one? I like and will copy your rx-antennas mounting

sure it will work

so cute

, abormor, which video frequency are you using? looks like a 900mhz-1.3ghz. I've done some big 1010mhz CL antennas, tired of keeping it from being bended @@

It's standalone osd (with dedicated gps...), I still like the way rushduino gets data directly from multiwii here .

I still cannot find max7456 here to build rushduino board, hunger to try it but I need to wait the chips to arrive

yeah it's sure

You can jump over to the latest dev version if you want. try ALTHOLD_FAST_THROTTLE_CHANGE & ALT_HOLD_THROTTLE_NEUTRAL_ZONE

vpb

Has someone used more than 1 sonar to implement object avoidance test?

vpb

And this one two (maybe the same)? m I think we must wait for modelci , Kataventos is working on original rushduino board I'm glad, developments continues with the highly assistances. This is last and final for Rushduino board. Then only will continue for Minim-osd. Because, I need to empty place fo...

vpb

You just need to choose Crius board in the config, that will define what it has and what it needs in def.h

vpb · Re: Altitude Hold improvement solution you can try 5-6 0.20 0.30-0.50

you can try 5-6 0.20 0.30-0.50

vpb

nice to hear that, with smaller one I've never got fixex in house

. But I think what we need is the stable signal outside, when flying far and high, that's important. I sometimes loose the signal without any reason, it's very dangerous.

vpb

you can always checkout latest version, it's ok! i'm flying r1275.

vpb

so all "sad" people here can't live without alt-hold ? and MultiWii is just that? It's improved (thanks to Mahowik) and will be improved again by someone later, there're good coders are flying multiwii out there. Alt-hold is acceptable now? I see so many interesting features outside this t...

Horizon is just angle, so it uses the same PID settings. You can tune in angle or horizon mode. But I think you should tune in horizon mode when hovering around, when moving forward, how the angle-correction acts when you release the sticks... this is incorrect and misleading information. read the ...

Yes, it's mixed between acro & level prop = max(abs(rcCommand[PITCH]),abs(rcCommand[ROLL])); // range [0;500] if ( f.HORIZON_MODE && axis<2) { PTerm = ((int32_t)PTermACC*(500-prop) + (int32_t)PTermGYRO*prop)/500; ITerm = ((int32_t)ITermACC*(500-prop) + (int32_t)ITermGYRO*prop)/500; } els...

Ya, I fly with horizon mode all the time FPV and non-fpv flight. With old level mode, I felt like trying to fight against the machine just to move around , I think guys who want to understand horizon mode just try it on field. My Level PID is 4.0/0.30/85. Level D is really like a damper, lowering it...

You've done a big improvement Mahowik, I guess dramida will miss you much

I can only speak for myself here: I always have a hard time merging code that is to complicated for me to understand. I could fuck up the code without knowing why and how should I fix thise bugs... You merge the code manually by hand? without the confliction code, you can always merge code by comma...

vpb

I don't get it: And in case the code is no longer availabe on Mahowik branch, i attached a zip file with the MWC source code you see flying in video above. Hi dramida, if you want a merged version that Mahowik did on the main trunk, just checkout the version before he removed it svn co http://multi...

vpb

I use horizon mode + alt-hold + gps-hold without any problem. Horizon mode is easier to fly than old angle mode. I spent time reading the difference between two but it's true that you should try it, it's very nice, something like you move around with acro-mode and when you stop (neutral sticks) the ...

vpb

Hi kataventos, can you share your board pictures? I've ordered Frsky FS100 current sensor to integrate with current frsky code, do you have any experiment on that sensor with Multiwii?

vpb

take a look at POWERMETER, but I think we must use POWERMETER_HARD for the precision reading.

vpb

On r1271, mahowik has rolled back with log message: "rollback changes as not stable yet...".
I'm still flying ok, hello Mahowik?

vpb

can sb show me the "like" button?

, omg I cant wait to build that, hope that I'll find max7456 & atmega328p at the near local shop.

vpb

i use it with r1268 without any problem.

thank you dramida! will try to tweak gps pos hold PID, it's been in my to-do list for a long time

. With default PID, and alt-hold activated, it moves around 2-3m. Can you share a clip?
