* functionalities of the Low Power Timer (LPTIM) peripheral:
|

* + Initialization and de-initialization functions.
|
||||
* + Start/Stop operation functions in polling mode.
|

##### 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 HSI).
|
||||
(+++) Prescaler: select the clock divider.
|
||||
(#)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 @ref HAL_LPTIM_RegisterCallback() to register a callback.
|
||||
@ref HAL_LPTIM_RegisterCallback() takes as parameters the HAL peripheral handle,
|
||||
the Callback ID and a pointer to the user callback function.
|
||||
[..]
|
||||
Use function @ref HAL_LPTIM_UnRegisterCallback() to reset a callback to the
|
||||
default weak function.
|
||||
@ref 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 @ref HAL_LPTIM_TriggerCallback(), @ref 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 @ref 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.
