##### 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_LPTIM1_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: Only LPTIM1 is present in STM32L053xx.
|
|
(##) 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.
