Re: Subject: Re: [Paparazzi-devel] AHRS over SPI on Tiny

[Andrew S]

Hello

I could extend this with equations - how to do this in a fixed wing aircraft without magnethometer. It tested for many hours of fly and works perfectly with cheap gyros.  But only if somebody would agree to correct my english before... :) Who can?

Hello,
one question: In the Wiki there is  described that a group  integratedthe ArduIMU  for Paparazzi by ZHAW,
Winterthur, Switzerland. It is possible  that there share  the code?

Christophe i think it is a good  idea if you take you explanations inthe paparazzi wiki..
 
It is known if the linear accelerations C  are occur.  A=B+C+D  This isknow if  the norm  of the measured accelerations is not equal g. aftersubtracting D. D is  v x  w. The cross product of the linear speed vwith the measured  rates.
 
 Regards
Heinrich

Hi all,

 

We are currently using the dydronesimu v2 board along with papparazi , The needed Gps data is taken fromthe tiny and feed into IMU via SPI then the computed angles feed to thetiny by SPI. Currently there is some problems with SPI......

 

The razor is based on the IMUv2 andcan run his code with some mods.

 

I have done static and dynamic test(roundabout driving) and the performance is very good..... and I getvery good support as one of the developers is local to me.

 

By the way I don´t do anyprogramming ,I´m only the pilot ....
