* Description:
|
|
* Initialize the selected I2C port. And return a unique instance of struct
|
|
* struct i2c_master_s. This function may be called to obtain multiple

|
|
*
|
|
* Input Parameters:
|
|
* Port number (for hardware that has multiple I2C interfaces)
|
|
*
|
|
* Returned Value:
|
|
* Valid I2C device structure reference on success; a NULL on failure
