Stellaris LaunchPad IMU.

Recommended Posts

With the caveat that I connected my GY-80 to a MSP430 Launchpad and so far only played with the pressure sensor: For me it is sufficient to connect VCC_3.3V to the Launchpad VCC, leaving VCC_IN unconnected.

 

Nice work with the impromptu booster pack. I guess I found my weekend project :)

Hi,

 

don't know if you've seen this: http://www.ti.com/tool/boostxl-senshub - the Sensor-Hub Booster Pack.

 

The hardware resembles and IMU too, but, what makes this a precious gem - is the software that comes with it: a set of functions to deal with the sensors, and a 9 axis sensor fusion code (and a nice I2C driver which uses interrupts!).

 

Don't miss this! Will save you a lot of work!

Awesome! I was in the middle of doing the same thing by hand. I bought a very cheap GY80 clone off ebay, and so far I've managed to read the accel and gyro. I haven't messed with the magnetometer nor barometric pressure sensor yet. I think your work will be a good resource to get my IMU finished and ready for my experimental quad based on the Stellaris.

There's also this very nice library FreeIMU: a libre 9DOM/DOF inertial measurement unit (zip)

 

It uses advanced algorithms —quaternions— and compute different angles —raw-pitch-roll and Euler.

 

Fabio, the author, has fully documented the library with a MoS Thesis: Using Arduino for Tangible Human Computer Interaction

unfortunately i wasnt able to download it as a zip file(a comple CCS project) so i was asking if  there anyone here kind enough to attach the project zip file here so i can be able to import it into CCS
