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).
