This code includes FRDM-STBC-AGM01 in order to add 9dof Sensor Fusion to Nerf Gun Demo. 9dof = accelerometer, magnetometer and gyro.

Fork of FRDM-STBC-AGM01 by angus taggart

The goal of this project is to incorporate sensor fusion capability to the already existing Nerf Gun Demo. The demo is controlled using Freescale's FRDM-K64F. I'm looking to add the FRDM-STBC-AGM01 to the project, which not only has FSL's combo accelerometer and magnetometer part FXOS8700Q but also FSL's gyro part FXAS21000. Hopefully the combination of all three sensors for 9dof sensor fusion will improve the mobility and control of the the demo's movement.

Details of the project can be found on the Freescale online community at https://community.freescale.com/groups/demolab/projects/fun-with-sensorfusion-nerf-gun-and-openrov-projects.
