problem with submodule #5

Closed ckchow closed 10 years ago

ckchow commented 10 years ago

I'm including your project as a submodule and whenever I checkout the branch with your project I get an error "No submodule mapping found in .gitmodules for path 'libraries/l3g'". This doesn't prevent me from using the rest of the module but it is a tiny bit bothersome. I think this means l3g wasn't added to FreeIMU correctly but I'm not sure.

You are probably correct - new to github. the l3g module is for the Altimu-10 IMU from Pololu so if you are not using that IMU it will make little difference. The l3g library can be downloaded from here until I get it fixed: https://github.com/pololu/l3g-arduino.git.

Hi Chris Just for reference properly linked the l3g submodule from Pololu but the actual l3g library is in a subfolder. Go figure. Anyway just as a heads up I am getting ready to change the AHRS algorithm which is based on the Madgwick implementation of the Mahoney filter to his gradient descent (MARG) method. Preliminary results seem good but need to do a long duration test on the drift.
