Get fresh r1117 version from repository, and UBLOX should work propertly.
I'm rewrite some pieces of UBLOX parser, and fix it.
Tested on Crius AIO Pro with RC-Timer UBLOX module.

is this error also in the i2c GPS Code ?

Hi ,

have anyone try to move the "SONAR_PING" to pin A3 ?
will that work ?

Hi , since we have more and more functions , i need some more channels Is it possible to read more than 8 PPM Channels with the Mwii Code ? Here is the Part for read the PPM Channels (I think ) #if defined(SERIAL_SUM_PPM) void rxInt() { uint16_t now,diff; static uint16_t last = 0; static uint8_t cha...

LuFa

of course , I want it for example

can you post your change here ?

LuFa

thats know the right plase to ask question about gps :

LuFa

cencen , wich Acc did you use ?
did you have also make a test in a altitude >= 10m ?

LuFa

i know , but i cant calculate it , because i get a different Result . is somewhat difficult for me to explain it in english. for german people : Das Problem dabei ist , wenn ich das Beispiel nachrechne bekomme ich ein anderes Ergebnis als das richtige von dem Beispiel .

Hi , I need some help with the calculation of the PLEVELDIV . My sensor outout 10mV/A . if i use this formel : 37 / 4.9 * 10e6 / 18000 * 3600 / 1000 from the example , the Result from my is totaly different with this from the Example . So can anyone tell my the right Result for my sensor (10mV/A) ? BG

Hello Mwii Fan´s My GPS work now realy good , and im very happy about it .

thanks

Hi ,

Is it possible to use two magnetometer at the same time ?
sometimes my mag. have a "jump" for a short time .
So i think its a good idea to use a second magnetometer for a better result .

Ideas are welcome

LuFa

Hi , What is the best way to calibrate the magnetometer ? In the gui we have the button "calib. mag." but cant find any info how it works . My last info is , Klick on the calibrate button and move the Mwii in all directions , thats all . I hope anywhere can tell me exactly how is the best ...

LuFa

ok , so if my mwii version works with R33 , it will also work with the newest version ?

LuFa

is the new i2c Code compatibel with the old one ?
because i doesnt fly the newest Mwii version

LuFa

ok , have change the name of the wire lib and now i can compile it without errors

news about i2c GPS and Ublox Parser

?

LuFa

did you have change the PID Parameter for the Ublox Parser ?

LuFa

Hi EosBandi ,

Great ! can you tell us how to add it into the I2C Code ?

thanks so mutch

EosBandi ,

Alexmos have done a very good fusion off ACC-Z and Baro

Did you have any Flightvideos of your code ?

Hi have test the code today to and it works great ! i fly with the Alexmos code R35 , is it possible to add this also in the Altitude hold mode ? @thornton : its a small bug , try this one : if (rcData[AUX1] > 1700) { int16_t errorAngleDelta=0; int16_t Iratecomp=0; static int16_t olderrorAngle[4]; e...

LuFa

ok , cool .
will test it tomorrow

did you think its possible to use it also with Altitude Hold ?

can you tell my what exactly your code do ?
is it a art of dynamic I term ?

LuFa

Hi i will test your change tomorrow But i dont unterstand the following : Put level p=0 and double level I to previously unflyable levels and see how it performs with your chance i have to put the P term to 0 ?

any news about the MS5611 and your Code ? After some morge Flights , my best PID Values are : P:20 I:0.005 D:15 , with this setup the Baro works very great but the Sonar have some proplems .

ok , have test it know .
but doesnt work to

Hi

can anyone tell me where i can find the newest I2C GPS Nav code for the newest Mwii dev ?
on the googlecode site from eosbandi i can only find r33 , but i have read about a the new nav rate controller and cant find it .

thanks

LuFa

Hi Eos ,

sounds great !
can you tell us how did you config the Ublox modul ? via u-center ?
did you have a config file ?

LuFa

ok

did you plan to make a update of your code to the newest dev ?
because the 2.0 have the old GPS Code and it will be very nice to use the New GPS from Eosbandi with your OpticalFlow together

thanks a lot !

LuFa

Hi Alexmos , Now i have flight 20 Batterys and have make a lot of tests with Different PID Settings and with/without Sonarsensor . My result is : - Without Sonarsensor it is possible to minimize the Proplem but not to remove it comlete - Thatswhy i have Connect my HC-SR04 Sonarsensor - With Sonar it...

LuFa

some tests later

i have found out that the proplem is only in low alt. around 1m .
Now i connect my Sonar Sensor and make some new tests

what did you mean with " calibrate your ACC by six points " ? how does it work ?

Thanks

LuFa

Now i have change all PID Parameter but the Proplem is not realy remove

I have found that the proplem is smaller with a Small I term and a high D term .
My Parameters for the moment are P 10 I 0.003 D 23 , thats the best result for the moment , but after some times the proplem comes back

LuFa

Hi , today i have upload the r35 from alexmos to test the altohold I use the MS5611 baro sensor .

Hi ,

today i have test your corrected code , but Optical flow doesnt work

Did you have found another error in my code ?

maybe its a proplem of my hardware , to exclude that i will make a second test with your code tomorrow

LuFa

thank you very mutch

the rest was ok ?

LuFa

no error found ?

i think this code works and its only a proplem of the method how to write the PID Values correct directly in the code .
With your code (i think r23) the Values P 5.0 and I 0.010 works very great , but i dont know how to write this correct with #define .

Thanks

LuFa

thank you very very mutch !!

now i have add OPTICAL_FLOW_P_GAIN and OPTICAL_FLOW_I_GAIN .

my parameter for the moment are : P 5.0 and I 0.010 , what is the right method to write this directly in the code ?
because OPTICAL_FLOW_I_GAIN 0.100 doesnt work how to write it correct ?

no idea ?

LuFa

ok thanks

will test it ...

LuFa

ok thanks

at the moment i fly with your current code , and i can say it works very good !

can you tell my how i can set the volt trigger to 4s ?

I'm working on GPS integration right now

GPS integration for Hott Telemetry ?
