    Problems with I2C device

    Clayton Hofrock

      I have a simple I2C 3 axis gyroscope device( Gyroscope Module 3-Axis L3G4200D | learn.parallax.comhttp://www.radioshack.com/product/index.jsp?productId=12310182)


      The device works fine with my adruino devices, but when I connect it to my Galileo, it does not work properly.

      I have reduced the sketch to a single I2C write. (single_i2c.ino)


      I have connected up a logic analyzer to record what is happening on SCL and SDA. I captured the single I2C write with both the Uno and the Galileo.


      I have attached a spreadsheet that has both the raw data (1s and 0s) and the decoded I2C data for both the Galileo and the Uno.
