Functions
HAL_StatusTypeDef	HAL_Init (void)
	This function is used to initialize the HAL Library; it must be the first instruction to be executed in the main program (before to call any other HAL function), it performs the following: Configure the Flash prefetch, instruction and Data caches. Configures the SysTick to generate an interrupt each 1 millisecond, which is clocked by the HSI (at this stage, the clock is not yet configured and thus the system is running from the internal HSI at 16 MHz). Set NVIC Group Priority to 4. Calls the HAL_MspInit() callback function defined in user file "stm32f4xx_hal_msp.c" to do the global low level hardware initialization.
HAL_StatusTypeDef	HAL_DeInit (void)
	This function de-Initializes common part of the HAL and stops the systick. This function is optional.
void	HAL_MspInit (void)
	Initialize the MSP.
void	HAL_MspDeInit (void)
	DeInitializes the MSP.
HAL_StatusTypeDef	HAL_InitTick (uint32_t TickPriority)
	This function configures the source of the time base. The time source is configured to have 1ms time base with a dedicated Tick interrupt priority.
void	HAL_IncTick (void)
	This function is called to increment a global variable "uwTick" used as application time base.
uint32_t	HAL_GetTick (void)
	Provides a tick value in millisecond.
uint32_t	HAL_GetTickPrio (void)
	This function returns a tick priority.
HAL_StatusTypeDef	HAL_SetTickFreq (HAL_TickFreqTypeDef Freq)
	Set new tick Freq.
HAL_TickFreqTypeDef	HAL_GetTickFreq (void)
	Return tick frequency.
void	HAL_Delay (uint32_t Delay)
	This function provides minimum delay (in milliseconds) based on variable incremented.
void	HAL_SuspendTick (void)
	Suspend Tick increment.
void	HAL_ResumeTick (void)
	Resume Tick increment.
uint32_t	HAL_GetHalVersion (void)
	Returns the HAL revision.
uint32_t	HAL_GetREVID (void)
	Returns the device revision identifier.
uint32_t	HAL_GetDEVID (void)
	Returns the device identifier.
void	HAL_DBGMCU_EnableDBGSleepMode (void)
	Enable the Debug Module during SLEEP mode.
void	HAL_DBGMCU_DisableDBGSleepMode (void)
	Disable the Debug Module during SLEEP mode.
void	HAL_DBGMCU_EnableDBGStopMode (void)
	Enable the Debug Module during STOP mode.
void	HAL_DBGMCU_DisableDBGStopMode (void)
	Disable the Debug Module during STOP mode.
void	HAL_DBGMCU_EnableDBGStandbyMode (void)
	Enable the Debug Module during STANDBY mode.
void	HAL_DBGMCU_DisableDBGStandbyMode (void)
	Disable the Debug Module during STANDBY mode.
void	HAL_EnableCompensationCell (void)
	Enables the I/O Compensation Cell.
void	HAL_DisableCompensationCell (void)
	Power-down the I/O Compensation Cell.
uint32_t	HAL_GetUIDw0 (void)
	Returns first word of the unique device identifier (UID based on 96 bits)
uint32_t	HAL_GetUIDw1 (void)
	Returns second word of the unique device identifier (UID based on 96 bits)
uint32_t	HAL_GetUIDw2 (void)
	Returns third word of the unique device identifier (UID based on 96 bits)

Variables
__IO uint32_t	uwTick
uint32_t	uwTickPrio = (1UL << __NVIC_PRIO_BITS)
HAL_TickFreqTypeDef	uwTickFreq = HAL_TICK_FREQ_DEFAULT

==============================================================================
  [..]
  The common HAL driver contains a set of generic and common APIs that can be
  used by the PPP peripheral drivers and the user to start using the HAL. 
  [..]
  The HAL contains two APIs' categories: 
       (+) Common HAL APIs
       (+) Services HAL APIs
