First of all, is there another forum for FreeIMU discussion? I'd rather not clutter up a Teensy-specific forum with general questions.
On to technical questions:
1) The newer version of I2Cdev that comes with the MPU-9150 (from SparkFun) removed the use of SPI, but the FreeIMU libraries still use it. This is causing a problem when trying to integrate the two. Is SPI still needed? Can I remove it from FreeIMU?
2) What part of FreeIMU actually contains the motion fusion algorithms? There are several example projects, and it is not clear what each is meant for...
