This function + configures mainly: + (##) The instance: LPTIM1. + (##) 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 possibles. + (##) UpdateMode: specifies whether the update of the autoreload and + the compare values is done immediately or after the end of current + period. + + (#)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. + + (##) 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. + + (#)Call HAL_LPTIM_DeInit() to deinitialize the LPTIM peripheral. + + @endverbatim + ****************************************************************************** + * @attention + * + * <h2><center>© COPYRIGHT(c) 2015 STMicroelectronics</center></h2> + * + * Redistribution and use in source and binary forms, with or without modification, + * are permitted provided that the following conditions are met: + * 1.
