best way to just get pitch data from arduimu

i would just like to send only pitch angle data from arduimu to another arduino

 

my understanding of code is poor

 

i would like to know which of the following pieces of code i need to load onto the imu board to achieve this task?

 

which piece of code do i need to modify to send only pitch data?

additional questions

is the gps required for the DCM to work if i only want pitch attitude?

which ardu-imu would be best suited to my need?

Get the ArduIMU+ V2. Load up arduimu.pde and the rest of the files will load automatically. The GPS while not absolutely necessary, supposedly helps with centripetal force corrections in dynamic situations. It all depends on the type of application you have in mind. If you have a static application - you can save a lot of trouble by just using a tri-axis accelerometer.

If you are truly only interested in pitch AND the IMU will always have it's X axis aligned with its motion (this is the general assumption in the DCM code and why it works for airplanes but not for helicopters) then no, you do not need the gps to get good pitch information.

If you are trying to reduce the size of the code you can delete the gps files, the pressure altitude file and the compass file. However, you may need to patch the code a bit to compile with these files absent.

http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1267759859 seams to offer a solution without messing around with code i dont understand.

i am also looking for any info on 'autopilot feedback control loops?' to control pitch through a rudder on something like this thing given that X axis pointing forward, Y axis running through the kite string and Z axis pointing down running through the wing.
