MultiWii

Hi, I recently been trying to upgrade to 2.2 - Everything works fine except that I cannot recalibrate the gyro or Acc with the usual TX stick combos- All other versions of the software calibrate w/ no problem ( I was previously using dev1143 ) Ive tried : clearing EEprom and resetting TX trims and s...

hey guys, I havent been following along on the alt hold progress so forgive me if Im missing something obvious in config or something... Ive tried the last two new dev versions- 1129 & 1143, and everything is great except for alt hold (I have a bmp085, PID= default @ 1.6/ .015/ 7)- Starting at a...

Dude, ALL the summer has been here in the US! (pant)

I guess Im the only one who has everything soldered directly= servo connectors are removed and no headers.

Good advice, but I was think more about changing the battery settings, timing, etc.; than throttle calibration, per say.

Hey, this may have already been considered (and dismissed) but... I was thinking it would be helpful if there was a simple way to access all the esc's for manual programming (via transmitter sticks.) Something like the current "calibrate throttle" procedure, but instead of the arduino doin...

Good to hear Im not alone- Mine doesnt go all the way to the ground but if it is returning home at about 30' it'll drop to about 8'. edit- just did a test flight, and after returning home it (after turning to face original orientation) it does slowly descend, and will touch the ground unless I give ...

baro is not necessary... but something I noticed.... Unless baro/ alt hold is toggled "on", it seems like my quad always wants drop altitude upon returning home. Is this just my imagination( a result of wind/ switching from ff to a hover) or is it returning to the original "home"...

There is (or at least was, with the prev dev's) necessary patch to get reliable gps data. Look back a few pages-

Is optical currently available in the latest dev version? I cant find anything about it in config.h or other tabs but is listed in the GUI. (tho' the box is black not brown like the other available sensors- I assume not a good sign)

yeah hoping I can at least use mine for optical and multiplexed sonar- if my copter will even take off with all the weight.

Pyrofer- make sure you get those two patches tommie posted a page or two back. Without, GPS data is really erratic and RTH and PH are disabled.

yes, mine is working well. I use a second "pro-mini" and mtk3339 gps.

tiny gps is a dead end since new nav functions will not fit into the atmega328 memory

bummer. i just built one.

hey, anyone else get to try out RTH & PH yet? BTW- here's a tip for those using a arduino as ISP programmer: I had a hell of a time getting it to work until I found this: (sorry , cant find link now, - Ill edit it in later) I am using a uno and arduino 1.0- apparently some have trouble flashing ...

Using lastest dev- tried it- just that one line? #if defined(GPS_SERIAL) || defined(TINY_GPS) - better but still not right. it now responds to RTH, but my 'copter and I seem to disagree where home is. I performed lots of gyro recalib to make sure it knew,but no change. POS still really has no effect...

OK- just did a test flight. I think that there may be a problem- it flew like the gps info had no influence on the craft at all. Toggling poshold- it would continue to drift with no perceivable correction in flight. Return to home- it made no effort to return. Didnt even turn around. Im guessing tha...

Ok-I think its all working properly. Is there currently any use of the optical function? I have a few ad5050's and some disposable camera lenses to play with. Not a priority, but it would be helpful if the LED functionality was increased - different "blinks" to indicate the state of GPS co...

Ok- replaced those lines in gps.ino (latest dev version)- and things look way more stable- last 2 digits (lan and lon) change, but seems consistent with I2cGPS performance. Distance to home still is reading 6084 or something (changes slightly with lan+lon) - also still no flashing ring. edit- neverm...

ok- that patch is for 2.0, right?

Heres a like second or two worth of lines read using the arduino I2c read sketch posted on pg 7: Request: 3 13 6 12 0 0 0 40 41 38 3 73 55 118 18 244 255 4 1 5 0 0 0 0 255 255 255 255 255 255 Request: 3 13 6 12 0 0 0 40 41 38 3 73 55 118 34 244 255 2 1 5 0 0 0 0 255 255 255 255 255 255 Request: 3 13...

Katch, did you get to fly? How's it work? i still cant get a decent fix- the GPS values in the GUI are constantly jumping around (especially the last 5 digits of lat and lon) and there is no flashing donut, ever. Against my better judgment, I did a test flight and it was all over the place. Any idea...

make sure that you have all the init stuff un-commented in config.h. I missed it the first time I programed my attiny. Pretty sure it is working now, though I didnt fully test my gps to see if it reset to the default baud/refresh rates after removing the battery. The problem Im having is that the GP...

great! Ill test it out later.

Tommie- congrats on tiny gps making it to the lastest dev! I saw the sonar contrioled landing lights-, cool- Is the optical fuctional? Actually I was going to ask to same thing about the init command- unfortunately, I only have a mac - currently no windows access and unable to run the mediatek confi...

you are right that solution for serial gps (also possible on 328 when GUI off)... for i2c GPS u can use this http://www.multiwii.com/forum/viewtopic.php?f=8&t=649&start=610#p14024 actually it's the same but with common Serial lib usage... Thanks! that does the trick. ( Worst thing was that ...

I kinda thought thats what was going on but wanted to wait until the dust settled before asking questions. Good chance Im mistaken, but it appears to me that this solution is for mega/serial gps- as the changes are to MultiWii. --Using a 328 for the FC so Im trying to get I2c-gps with a second pro m...

Yeah, kinda dont want to have to buy/install windows. my old windows PC is dead( wont boot) so I may be out of options. Flashing/ setting up the mkt3339 is a one time thing, right?, so i may just try to use a friend's PC.

Im in the same boat - I just got the mtk 3339 - heh,and Im a mac user, am I gonna have to dig my old windowsXP tower outta the basement to get I2c gps setup?, ughh.

I believe there are a few tweaks to parts of the multiwii code necessary for the i2c from tiny-gps to be recognized/read by the FC. Tommie has posted a modified version of 2.0 with the necessary changes, but with all the recent GPS progress it is getting out dated. Would be great if tiny-gps compati...

I'd like to tiny-gps merged into the latest devs.

heh, We need to start a "petition"

Hey, just order some parts- cant wait to build the tiny-gps! Have the patches been merged in the lasted devs?

Interested -just sent you a PM
Charlie

Just tried the new DEV- stable mode is greatly improved,way less drift than 2.0. very stable! The GUI looks great too. sonar and optical support... awesome!
