rotation vector in rc_altitude.c #118

Closed rahulsharma11 closed 6 years ago

rahulsharma11 commented 6 years ago

Hi @StrawsonDesign , Can you please help me to understand the working principal in IMU filteration that is being used in rc_altitude.c As for what purpose "rc_quaternion_rotate_vector_array(accel_vec,mpu_data.dmp_quat)" is required before filter? What does it actually do? then what are the steps that are needed further etc? I want to understand it's flow so that i can proceed to make a separate code for 2D position estimation with imu integration. Will appreciate your help. Thanks.

Or is any slack/any account for roboticscape there? so that discussion can be made over ther.

I just made a slack channel here https://beagleboard.slack.com/messages/CBLPQ5MN2/details/

if that doesn't work please send your email so I can invite you manually.

Hi, Any update?

StrawsonDesign commented 6 years ago

just invited your email, and figured out that you need a specific link to get access, not just the main slack page. Sorry, I'm new to slack!

new page is in the header of the documentation website and the github README, I hope others will join us, I like your suggestion.
