  I am trying to run a breakout light sensor board using I2C and at the same time run a CC3000 wifi breakout board. I can

  confirm that both cards work as expected, separately. The problem comes when we try to use these boards at the same time.

  For the light sensor we are using B8 and B9 for SLC and SDA and it works fine. But the wifi board uses B8 for IRQ and I

  presume that this is set in the module. I noticed that B10 and B11 can be used as for I2C SLC and SDA but when I use these

  pins the with the light sensor board I get timeout errors. I am connecting using I2C2 function but I have tried using I2C1

  as well without success.

  So I see 2 options; work out why B10 and B11 aren't working with I2C or change the CC3000 module so that it uses another

  pin from B8.

  Does anyone have any suggestions on either options?
