Hi there, well, I'm a little bit surprise to here from you guys that your quad isn't stable when using the ATMEL IMU. I'm using the sensors on my flyduspider and I must say that it's PERFECTLY STABLE! I'm running the I2C bus at 400kHz, connected to an LLC. If the IMU would behave bad because of the...

captaingeek

FYI - imo this board at this time with the current coding is not worth the trouble as stable mode is not working correctly yet from my test.

captaingeek

darn didnt realize this was released was fighting the atmel i1 acc all weekend trying to get it working with 1.8p2. havnt been able to get stable mode working right with that board no matter what ive tried.

captaingeek

$9.99 sounds likea good deal.

captaingeek

alex's link to the faq post was indicating that this is normal behaviour and should be ignored: The motor output on the GUI is not equal on both sides with a neutral RC input This is the normal PID loop behaviour, the I-term is actually cumulating the error over time & tries to compensate for th...

captaingeek

so... with 1.8 being out for awhile... what have folks settled in with LPF and PID settings?

captaingeek

have you tuned it in acro only mode?

captaingeek

Here's my current seetings and I like how it hovers. but is fast flight it starts dropping. why?

here's my pid settings:

captaingeek

i find it hard to beleive that the mwc is locking up unless youve dont somthing to the code. mine have never done that and I've used 1.5 - current.

captaingeek

let us know how she flies

captaingeek

sounds like a lot of trouble. this is one of the reasons i use motor stop.

Hello guys, this module its compatible with us copters. There are two androids App with works with the MultiWii system. http://wbb.multiwii.com/viewtopic.php?f=8&t=248 http://www.rcgroups.com/forums/showpost.php?p=18050473&postcount=1 Great configuration tutorial from Berkely http://wbb.mul...

captaingeek

how many ticks? try 10 - 20. not sure what the max is.

i tried using this but am having trouble. ive uploaded the firmware, and opened the GUI. It seems to be working somewhat... i can see the sliders and the buttons to enable / disable each motor. i can read write settings. but when I active the throttle the motors wont spin. when I activate throttle t...

captaingeek

hmmm thats pretty cool. you could make a really cheap tri / quad with this and old brushed motors. im thinking of the brushed motors extracted from used electric toothbrushes.

captaingeek

Anyone actually try connecting one of these things to a 5V arduino and see what happens? I have a Bt module with an adaptor board, which does not have the voltage divider resistors. I can't be bothered adding them, and was wondering if anyone has got away with it? I have toyed with connecting the B...

captaingeek

this is pretty cool

captaingeek

hi im thinking about picking one of these up. is goodluckbuy the way to go?

also has anyone ggotten it working with a droidx?

thanks!!

captaingeek

very nice. im curious what makes you a bugs work nightmare? do you flying your copter into swarms of bugs?

captaingeek

had a great night of flying myself. with this board and baro everything worked as expected. was able to stay within about a 50' box in stable mode and 30' of alt. The heading hold works pretty good too.

captaingeek

so has anyone gotten stable mode working stable with this board?

captaingeek

if it is im not aware of how to enable it or configure.

I think if you could make the LED / Pin 13 blink when the battery was low that would be awesome!

bonus for making it blink slowly at 40%, medium at 30 and fast below 20%.

captaingeek

Try lowering the LPF.

captaingeek

increase the throws to 125%

captaingeek

hmmmm nice

captaingeek

im sure you had a feeling this was gona be coming but first crash / hard landing its gona break.

but hey why the heck not

captaingeek

here's what im runnin currently... lowering I helped quite a bit for level mode. I noticed the cycle time bouncing from 3300 to 3800ms.

Is the lpf setting integrated when defining ATAVRSBIN1? I'm flying 1.8 with only the defaults havn't touched the #define ITG3200_LPF_XX settings. MAIN SOFT: more settings are avalaible for the ITG3200 gyro there was also a bug regarding the ITG3200 initialisation which is corrected => 2000deg/s sett...

captaingeek

after testing last night I'm still seeing some issues with level mode. I'm using an atmel i1 sensor board. hovers and flys great in acro mode. in level mode, i can set it so that it will hover perfectly level down close to the ground and that works good. but when I goto altitude to setup in hover in...

captaingeek

test flew with 1.8 this morning flew great. I didnt adjust the LPF settings and it flew fine. has the LPF filter setting been defined by default when the i1 is uncommented?

captaingeek

test flown this morning with the atmel i1. flew great with defaults. upped p's for pitch/roll. amazingly stable in level mode. adding a baro now.

captaingeek

yahhoooo! cant wait to test.

after sitting still for 5 minutes

right after flying, sitting still on table:

captaingeek

which version are you running.

lets take the ESC's out of the equation. In the GUI, are the motor output's dancing?

captaingeek

captaingeek

3a apply 12v power to esc's
4 esc's will blip motors indicating that the max thottle point has been detected.

I cheat by removing 12v power from the ESC's, activating throttle on the FC and going max throttle, then quickly connect ESC's so they pick up max throttle. then onto step 5.

captaingeek

how are you calibrating the ESC's?

captaingeek

from what I've heard you shouldnt have to mess with the min/max.

reset those to defult then calibrate the ESC's.

you can also try reseting the yaw direction.

captaingeek

atmel i1 and current dev:

http://www.youtube.com/watch?v=MsbslvYMR8o

mag seems to work. havn't touched new settings other then that. stable mode takes quite a bit of software trim (20 clicks left aileron and 15 back) and tends to dwel a bit during flight testing.

captaingeek

im pretty happy with the performance. played around with stable mode a lot. most of the video below is in acro mode. in stable mode my model takes about 30 left aileron clicks and 10 back clicks of programming trim. it seems to dewl a bit too during flight testing with this sensor. mag is working we...

captaingeek

new fame dialed in quite nicely. this is in stable mode.

I increased roll and pitch P values yesterday a bit more last night. I think it can go a bit higher but am still fighting some bogging issues. Any heavy forward flight or movment and the quad wants to drop outta the air. One of the motors seems to be having issues. I think im going to give up on the...

captaingeek

lol OK - didn't even realize that would work! For mine I just hit calibrate while the model is still. its weird because the LED start's blink and didn't ever seem to stop so I figured there was somthing wrong witn the calibration routine.

captaingeek

1.8 hasn't been released. the dev code is just that, in dev. with that said. i have done some testing with the mag and it does work. have you calibrated it? i think it may need to swirled around a bit then calibrated like you do with an iphone. whats your pids look like? I'm try to dial myn in for f...

captaingeek

Alex - yes this is the case. This same copter flew fine with WMP/ADXL 345 only in 1.7. With this i1 sensor board it is unflyable until I set it at 42khz. Thanks guys. If I understand correctly on your setup: - it works great with 42Hz LPF (line #define ITG3200_LPF_42HZ un commented) - it doesn't wor...

captaingeek

im now running the same quad with the atmel ineria 1. with default pids in the current dev code MultiWii_dev20110714 and the itg3200 set at 42khz it was a bit floppy. i've dialed in the attached pids and am quite happy with the performance. still getting some bogging at around mid stick when the bat...
