    I2C is intended to operate on a bus. is there any reason why the two devices you intend to communicate with can't be set up with different addresses? Is the F28031 a master or slave on the I2C bus?

    That being said, your best bet is to bit-bang using GPIOs. I don't have example code, but I am aware that it has been done before.

    Thanks,
