+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The LPTIM HAL driver can be used as follows:
+
+ (#)Initialize the LPTIM low level resources by implementing the
+ HAL_LPTIM_MspInit():
+ (++) Enable the LPTIM interface clock using __HAL_RCC_LPTIMx_CLK_ENABLE().
+ (++) In case of using interrupts (e.g. HAL_LPTIM_PWM_Start_IT()):
+ (+++) Configure the LPTIM interrupt priority using HAL_NVIC_SetPriority().
+ (+++) Enable the LPTIM IRQ handler using HAL_NVIC_EnableIRQ().
+ (+++) In LPTIM IRQ handler, call HAL_LPTIM_IRQHandler().
+
+ (#)Initialize the LPTIM HAL using HAL_LPTIM_Init(). This function
+ configures mainly:
+ (++) The instance: LPTIM1 or LPTIM2.
+ (++) Clock: the counter clock.
+ (+++) Source : it can be either the ULPTIM input (IN1) or one of
+ the internal clock; (APB, LSE, LSI or MSI).
+ (+++) Prescaler: select the clock divider.
+ (++) UltraLowPowerClock : To be used only if the ULPTIM is selected
+ as counter clock source.
+ (+++) Polarity: polarity of the active edge for the counter unit
+ if the ULPTIM input is selected.
+ (+++) SampleTime: clock sampling time to configure the clock glitch
+ filter.
+ (++) Trigger: How the counter start.
+ (+++) Source: trigger can be software or one of the hardware triggers.
+ (+++) ActiveEdge : only for hardware trigger.
+ (+++) SampleTime : trigger sampling time to configure the trigger
+ glitch filter.
+ (++) OutputPolarity : 2 opposite polarities are possible.
+ (++) UpdateMode: specifies whether the update of the autoreload and
+ the compare values is done immediately or after the end of current
+ period.
+ (++) Input1Source: Source selected for input1 (GPIO or comparator output).
+ (++) Input2Source: Source selected for input2 (GPIO or comparator output).
+ Input2 is used only for encoder feature so is used only for LPTIM1 instance.
+
+ (#)Six modes are available:
+
+ (++) PWM Mode: To generate a PWM signal with specified period and pulse,
+ call HAL_LPTIM_PWM_Start() or HAL_LPTIM_PWM_Start_IT() for interruption
+ mode.
+
+ (++) One Pulse Mode: To generate pulse with specified width in response
+ to a stimulus, call HAL_LPTIM_OnePulse_Start() or
+ HAL_LPTIM_OnePulse_Start_IT() for interruption mode.
+
+ (++) Set once Mode: In this mode, the output changes the level (from
+ low level to high level if the output polarity is configured high, else
+ the opposite) when a compare match occurs. To start this mode, call
+ HAL_LPTIM_SetOnce_Start() or HAL_LPTIM_SetOnce_Start_IT() for
+ interruption mode.
+
+ (++) Encoder Mode: To use the encoder interface call
+ HAL_LPTIM_Encoder_Start() or HAL_LPTIM_Encoder_Start_IT() for
+ interruption mode. Only available for LPTIM1 instance.
+
+ (++) Time out Mode: an active edge on one selected trigger input rests
+ the counter. The first trigger event will start the timer, any
+ successive trigger event will reset the counter and the timer will
+ restart. To start this mode call HAL_LPTIM_TimeOut_Start_IT() or
+ HAL_LPTIM_TimeOut_Start_IT() for interruption mode.
+
+ (++) Counter Mode: counter can be used to count external events on
+ the LPTIM Input1 or it can be used to count internal clock cycles.
+ To start this mode, call HAL_LPTIM_Counter_Start() or
+ HAL_LPTIM_Counter_Start_IT() for interruption mode.
+
+
+ (#) User can stop any process by calling the corresponding API:
+ HAL_LPTIM_Xxx_Stop() or HAL_LPTIM_Xxx_Stop_IT() if the process is
+ already started in interruption mode.
+
+ (#) De-initialize the LPTIM peripheral using HAL_LPTIM_DeInit().
+
+ *** Callback registration ***
+ =============================================
+ [..]
+ The compilation define USE_HAL_LPTIM_REGISTER_CALLBACKS when set to 1
+ allows the user to configure dynamically the driver callbacks.
+ [..]
+ Use Function HAL_LPTIM_RegisterCallback() to register a callback.
+ HAL_LPTIM_RegisterCallback() takes as parameters the HAL peripheral handle,
+ the Callback ID and a pointer to the user callback function.
+ [..]
+ Use function HAL_LPTIM_UnRegisterCallback() to reset a callback to the
+ default weak function.
+ HAL_LPTIM_UnRegisterCallback takes as parameters the HAL peripheral handle,
+ and the Callback ID.
+ [..]
+ These functions allow to register/unregister following callbacks:
+
+ (+) MspInitCallback : LPTIM Base Msp Init Callback.
+ (+) MspDeInitCallback : LPTIM Base Msp DeInit Callback.
+ (+) CompareMatchCallback : Compare match Callback.
+ (+) AutoReloadMatchCallback : Auto-reload match Callback.
+ (+) TriggerCallback : External trigger event detection Callback.
+ (+) CompareWriteCallback : Compare register write complete Callback.
+ (+) AutoReloadWriteCallback : Auto-reload register write complete Callback.
+ (+) DirectionUpCallback : Up-counting direction change Callback.
+ (+) DirectionDownCallback : Down-counting direction change Callback.
+
+ [..]
+ By default, after the Init and when the state is HAL_LPTIM_STATE_RESET
+ all interrupt callbacks are set to the corresponding weak functions:
+ examples HAL_LPTIM_TriggerCallback(), HAL_LPTIM_CompareMatchCallback().
+
+ [..]
+ Exception done for MspInit and MspDeInit functions that are reset to the legacy weak
+ functionalities in the Init/DeInit only when these callbacks are null
+ (not registered beforehand). If not, MspInit or MspDeInit are not null, the Init/DeInit
+ keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
+
+ [..]
+ Callbacks can be registered/unregistered in HAL_LPTIM_STATE_READY state only.
+ Exception done MspInit/MspDeInit that can be registered/unregistered
+ in HAL_LPTIM_STATE_READY or HAL_LPTIM_STATE_RESET state,
+ thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
+ In that case first register the MspInit/MspDeInit user callbacks
+ using HAL_LPTIM_RegisterCallback() before calling DeInit or Init function.
+
+ [..]
+ When The compilation define USE_HAL_LPTIM_REGISTER_CALLBACKS is set to 0 or
+ not defined, the callback registration feature is not available and all callbacks
+ are set to the corresponding weak functions.
