mbed_official	237:f3da66175598	21	The SMBUS HAL driver can be used as follows:
mbed_official	237:f3da66175598	22
mbed_official	237:f3da66175598	23	(#) Declare a SMBUS_HandleTypeDef handle structure, for example:

mbed_official	237:f3da66175598	25
mbed_official	237:f3da66175598	26	(#)Initialize the SMBUS low level resources by implement the HAL_SMBUS_MspInit ()API:
