    I2C dropping out on arduino expansion board only

    grauwl

      I'm having an issue with using I2C on the arduino expansion board. I'm trying to interface with a MPU-9150 sensor, and when checking for i2c devices either using i2cdetect or an arduino i2c scanner program, the sensor seems to randomly show up or not.

      It works perfectly with the edison mini expansion board as well as on an arduino uno board, so I'm not sure what's going wrong with the edison arduino breakout board...

      Has anybody else run into this problem and/or know how to fix it? Thanks.
