| 19 | ##### How to use this driver #####
|
---|
| 20 | ==============================================================================
|
---|
| 21 | [..]
|
---|
| 22 | The LPTIM HAL driver can be used as follows:
|
---|
| 23 |
|
---|
| 24 | (#)Initialize the LPTIM low level resources by implementing the
|
---|
| 25 | HAL_LPTIM_MspInit():
|
---|
| 26 | (##) Enable the LPTIM interface clock using __LPTIMx_CLK_ENABLE().
|
---|
| 27 | (##) In case of using interrupts (e.g. HAL_LPTIM_PWM_Start_IT()):
|
---|
| 28 | (+) Configure the LPTIM interrupt priority using HAL_NVIC_SetPriority().
|
---|
| 29 | (+) Enable the LPTIM IRQ handler using HAL_NVIC_EnableIRQ().
|
---|
| 30 | (+) In LPTIM IRQ handler, call HAL_LPTIM_IRQHandler().
|
---|
| 31 |
|
---|
| 32 | (#)Initialize the LPTIM HAL using HAL_LPTIM_Init(). This function
|
---|
| 33 | configures mainly:
|
---|
| 34 | (##) The instance: LPTIM1.
|
---|
| 35 | (##) Clock: the counter clock.
|
---|
| 36 | - Source : it can be either the ULPTIM input (IN1) or one of
|
---|
| 37 | the internal clock; (APB, LSE, LSI or MSI).
|
---|
| 38 | - Prescaler: select the clock divider.
|
---|
| 39 | (##) UltraLowPowerClock : To be used only if the ULPTIM is selected
|
---|
| 40 | as counter clock source.
|
---|
| 41 | - Polarity: polarity of the active edge for the counter unit
|
---|
| 42 | if the ULPTIM input is selected.
|
---|
| 43 | - SampleTime: clock sampling time to configure the clock glitch
|
---|
| 44 | filter.
|
---|
| 45 | (##) Trigger: How the counter start.
|
---|
| 46 | - Source: trigger can be software or one of the hardware triggers.
|
---|
| 47 | - ActiveEdge : only for hardware trigger.
|
---|
| 48 | - SampleTime : trigger sampling time to configure the trigger
|
---|
| 49 | glitch filter.
|
---|
| 50 | (##) OutputPolarity : 2 opposite polarities are possibles.
|
---|
| 51 | (##) UpdateMode: specifies whether the update of the autoreload and
|
---|
| 52 | the compare values is done immediately or after the end of current
|
---|
| 53 | period.
|
---|
| 54 |
|
---|
| 55 | (#)Six modes are available:
|
---|
| 56 |
|
---|
| 57 | (##) PWM Mode: To generate a PWM signal with specified period and pulse,
|
---|
| 58 | call HAL_LPTIM_PWM_Start() or HAL_LPTIM_PWM_Start_IT() for interruption
|
---|
| 59 | mode.
|
---|
| 60 |
|
---|
| 61 | (##) One Pulse Mode: To generate pulse with specified width in response
|
---|
| 62 | to a stimulus, call HAL_LPTIM_OnePulse_Start() or
|
---|
| 63 | HAL_LPTIM_OnePulse_Start_IT() for interruption mode.
|
---|
| 64 |
|
---|
| 65 | (##) Set once Mode: In this mode, the output changes the level (from
|
---|
| 66 | low level to high level if the output polarity is configured high, else
|
---|
| 67 | the opposite) when a compare match occurs. To start this mode, call
|
---|
| 68 | HAL_LPTIM_SetOnce_Start() or HAL_LPTIM_SetOnce_Start_IT() for
|
---|
| 69 | interruption mode.
|
---|
| 70 |
|
---|
| 71 | (##) Encoder Mode: To use the encoder interface call
|
---|
| 72 | HAL_LPTIM_Encoder_Start() or HAL_LPTIM_Encoder_Start_IT() for
|
---|
| 73 | interruption mode.
|
---|
| 74 |
|
---|
| 75 | (##) Time out Mode: an active edge on one selected trigger input rests
|
---|
| 76 | the counter. The first trigger event will start the timer, any
|
---|
| 77 | successive trigger event will reset the counter and the timer will
|
---|
| 78 | restart. To start this mode call HAL_LPTIM_TimeOut_Start_IT() or
|
---|
| 79 | HAL_LPTIM_TimeOut_Start_IT() for interruption mode.
|
---|
| 80 |
|
---|
| 81 | (##) Counter Mode: counter can be used to count external events on
|
---|
| 82 | the LPTIM Input1 or it can be used to count internal clock cycles.
|
---|
| 83 | To start this mode, call HAL_LPTIM_Counter_Start() or
|
---|
| 84 | HAL_LPTIM_Counter_Start_IT() for interruption mode.
|
---|
| 85 |
|
---|
| 86 | (#) User can stop any process by calling the corresponding API:
|
---|
| 87 | HAL_LPTIM_Xxx_Stop() or HAL_LPTIM_Xxx_Stop_IT() if the process is
|
---|
| 88 | already started in interruption mode.
|
---|
| 89 |
|
---|
| 90 | (#)Call HAL_LPTIM_DeInit() to deinitialize the LPTIM peripheral.
