Hello,
I have a 9DOF Sensor Stick (SENS-10724) from SparkFun, hooked up to a Teensy 3.1 via I2C. Vcc is connected to the 3.3V on the Teensy.
I am using the same setup as in this thread: http://forum.pjrc.com/threads/25432-Teensy-3-1-amp-freeIMU
Here is a pic of my setup:
Using the Wire Library I am able to turn on the device and output data to the Serial Monitor. The accelerometer gives reasonable values, but I am not for certain. The gyroscope and magnetometer seem to give maximum values of ~65530, that change when the chip is moving, but return to 65530 when sitting still. I have also tried using the RAZOR_AHRS arduino and processing sketches from this tutorial: https://github.com/ptrbrtz/razor-9dof-ahrs/wiki/Tutorial
I am able to get the AHRS sketches loaded and running, the processing sketch finds the serial port just fine, but all the values returned are zeros.
I am not sure where the problem lies at this point. As best as I can tell, I do not need pullup resistors on the SCL and SDA connections, since the 9DOF Stick has the 4.7K pullup resistors onboard? any help would be greatly appreciated.
Thank you,
