Greeting diydrones,
Before I'm buying the ArduIMU V3 I'd like to confirm a few things.
I'm interested in connecting the ArduIMU V3 to another Arduino and having the second Arduino control a quadcopter according to the data received from the ArduIMU. Can the ArduIMU provide the current orientation in respect to the ground and North(So I can use inertial navigation - I won't use GPS at first)?
If it is possible are there any guides/manuals that describe how to work with the ArduIMU V3 in that manner?
Thank you.

Hey buddy,
What part of code needs to be change in ArduIMU_1.9.8 Firmware if we want to use ArduIMU running DCM on it without GPS..?
Thank You..!
I just tested ArduIMU without GPS, to use it just for Heading, Pitch and Roll measurement.
Results are bad, with big drifts on all values , but specially on heading.
I use V1.9 software, I use magnetometer and speedfilt , setting #define orders:
#define USE_MAGNETOMETER 1
#define SPEEDFILT 2
Perhaps I made a mystake ?
What about calibration ? I didn't find any information about arduIMU V3 calibration...
Is it possible to get accurate values of heading,pitch and roll without GPS ?
Many thanks.
Thank you for your reply, are there any output examples that include the magnetometer by any chance?
For example in the screenshot here: http://code.google.com/p/ardu-imu/wiki/Demo the magnetometer chart is empty(First picture, bottom left part).
Also, is it viable to use the ArduIMU V3 without a GPS module?
From the wiki page:
Which I find rather strange since it has a 3 axis Gyro, 3 axis accelerometer and a 3 axis magnetometer(Which is enough to correct drift on all angles as far as I understand).
I'm sure it can. You would use the serial port to communicate between the two. As far as guides/manuals... I don't know of anything available at all for the V3. I plan on setting up a wiki with information when I get some time. I will be doing the same thing of doing ArduIMU->Arduino soon.
