Kostas,
Short answer is no, there is no pre-programmed code in the CVS for measuring accels and gyros on the onboard ADC, converting them to usable units, and calculating roll,pitch,yaw values from them.  There is some code in sw/airborne/booz which does this from an external IMU source which may be of some use to you, but nothing exactly as you are looking.

hello there

i have buyed the tiny 2, accellerometers and gyros. i want to start using
those to test my airframe. what i want to do is to connect the gyros and the
accellerometers, control the dc brushless motors and measure the roll, pitch
and yaw angles. Are those measurements pre-programmed to the tiny??? Should
i make a code of my own?

Hello Everyone,

I am setting up my airframe to take still pictures using a Pentax Optio
A30 camera controlled remotely using PRISM IR emitter that under
ordinary circumstances would just plug directly into the receiver. In
other words, the PRISM controller works like a servo or typical actuator
as far as the ap is concerned. I started looking at the paparazzi code
and found dc.c and dc.h files under the sw/airborne directory. I also
found the dc.xml file in the conf/settings directory. There are even
buttons for the gcs under the picture directory. So it looks like
someone has done something similar before, but I can't find any
documentation or discussion about the topic. It could be that it is all
there already!

I setup the paparazzi center for a simulation using airframe -
funjet1.xml, flight_plan - versatile.xml, settings - dc.xml, radios -
T7cap.xml, and telemetry - default.xml. I keep getting the same build
error as reported below. Any ideas that anyone might have to get me
started in the right direction will be appreciated. Thanks much!!!!
