MultiWii

arnaldo

Hi, Tnx, Alex you made all dirty work for me.. I will try latest version today. BTW: Do we want additional feature "Throttele assistant"? Using only VEL PID alone gives really interesting behavior: It makes throttle adjustments really precise and soft and in theory it also should work wit...

arnaldo

can anyone make an executable dev with this upgrade ?!............alex?!?!?!?!?

arnaldo

I hope that Alex will add all these mod in his last dev

!

arnaldo

i'm using allinone with same conf of other dev...

arnaldo

yeah...the same problem before swap channel....when i pitch the arrow rotates

arnaldo

with last dev 529 mag doesn't work well like with 526

This looks good, can you share the code?

i can talk with ziojos.....

Hi Patrick, I discovered something interesting for your different tests: it's important to not smooth too much the baro output. A noisy output is better for baro reactivity, even if it's a little bouncy. I'm still sure there is something to do with the ZAcc. we have to find out how to use is at bes...

arnaldo

i tried 519 but doen't work well for me...

arnaldo

did anyone try last dev? can you have good resutls with baro mode?
i tried with different PID values but i'm not able to have a good alth hold.... at the moment the best Multiwii baro mode is that of Patricke

arnaldo

now mine works perfectly

This video shows how my compass works!
i think it works well on yaw movements...but i don't understand the error on pitch and roll!

arnaldo

this is a video test of your dev Patrik!

in mine all axes works fine...i don't understand why when i move on pitch roll axes the z axes rotate about 90 to 180 degree...
so qhen i go forward or backward the tail rotate...same thing on roll!

arnaldo

can you make me the file to test mag? i'm not so expert to make it...

arnaldo

with the last dev...5008...i can see correct values on z axes...but when i move it on pitch and roll axes...there is correct values on these axes...but also z axes rotate of 180degree...

arnaldo

with the last dev...5008...baro seems to work badly...it spin up 2 3 times and go into the stratosphere...
also compass works badly on pitch and roll axes....

arnaldo

druck....have you tried original DEV? baro and magneto work in flight? mine work in gui but not in flight...

arnaldo

i tried the first and the last dev.... they work... i don't know why in the original dev(alex dev) in the gui baro and compass work...but in flight when i switch them they don't work i think the best value is 2.... and when you switch baro you have to be stationary in altitude otherwise the quad sta...

arnaldo

hi patrick...why with your dev version baro and magneto work....with original dev...they work in gui...but not in flight...

however magneto also in your dev works badly....when i pitch or roll the arrov in gui turn...

arnaldo

where i can check that?

arnaldo

mmmm...i don't undesrtand....it's normal if i pitch the model forward about 50° to see the arrow rotates 90°???? it should be locked...however i will try in flight...
in 1,7 versione when...in flight i pitch the model...the tail turned(the same as in the gui) so flight was horrible...

arnaldo

mine is uder arduint that is in a capsule

no wind...no light

arnaldo

after calibration the problem is the same...

arnaldo

where is dev version?

ops...just read on rcgroups

arnaldo

i have the same problem...

arnaldo

ok...i will try it soon as possible....i see parameter 3 and 600?!?!?!?! woow....

arnaldo

Hello patrick...i tried your mod(first post) and it works with default parameter....i have a 0,5m of amplitude and sometimes 1meter...
can i try to change the first parameter??? i have to improve of 1 unit or much? how this parameter works?

arnaldo

i tried your mod druckgott, but it doesn't work for me...only one time at high altitude it worked for a while...
what i have to change? what do your values if changed?

arnaldo

i think for the next week i will try it!

arnaldo

you need a logical level converter for this board.

arnaldo

you can use a v tail servo mixer to use the same servo with arduino and with tx

arnaldo

try to change this(default 10Hz):
i2c_write(0x1D);

to this for 20Hz
i2c_write(0x1C);

or this for 42hz
i2c_write(0x1B);

i'm not sure...it requires the confirmation by alex!

arnaldo

sure...thank you alex!

arnaldo

do you think that the barometer in 1.7final will be improved

arnaldo

can you upload the complete executable package? you can use 4shared

arnaldo

no problem, there is a version with correct pin and hmc5883l

arnaldo

the seller said me that you can run arduino at 3,3....but i think for now the best choice is to use LLC.

i will ask him other info soon..

arnaldo

Hello guys, i wwould like to show you a new PCB board ALL IN ONE. http://www.rcgroups.com/forums/showatt.php?attachmentid=3895679&d=1301138059 this PCB includes the best sensor for our multicopter: -HMC5883 Triple Axis Magnetometer -BMA180 Triple Axis Accelerometer -BMP085 Barometric Pressure Se...

arnaldo

on my camera mount i added an extra pitch command...so i have 2 pitch control on the same pod...1 for arduino 1 for tx

arnaldo

good job Alex!

arnaldo

hello, I want to know if hmc5883 now works well, and if i using a wm+ and nunchuck I could run it at 400KHz

arnaldo

Hi, i bought another original Nunchuck, ut i discovered that is different by other!
What acc is it?
it seems to work fine.

arnaldo

compass works fine now? if i use wm+ and nunchuk how do i connect this?

arnaldo

i will add an extra pitch servo on my camera pod direclty connected to rx....so the stabilizator is indipendent by my pitch command...

arnaldo

arnaldo

yes for the same think, fpv flight is not simple with stabilization, however if i want to take a good video while i'm fliyng i have to put on the stabilizator...and put off for returning to home...
you can add a checkbox in the gui?

arnaldo

Alex can you add to aux channel also the enabling/disabling control for pitch-roll stabilization?!
