mbed_official 181:a4cbdfbbd2f4 19 ##### How to use this driver #####
mbed_official 181:a4cbdfbbd2f4 20 ==============================================================================
mbed_official 181:a4cbdfbbd2f4 21 [..]
mbed_official 181:a4cbdfbbd2f4 22 The LPTIM HAL driver can be used as follows:
mbed_official 181:a4cbdfbbd2f4 23
mbed_official 181:a4cbdfbbd2f4 24 (#)Initialize the LPTIM low level resources by implementing the
mbed_official 181:a4cbdfbbd2f4 25 HAL_LPTIM_MspInit():
mbed_official 181:a4cbdfbbd2f4 26 (##) Enable the LPTIM interface clock using __LPTIM1_CLK_ENABLE().
mbed_official 181:a4cbdfbbd2f4 27 (##) In case of using interrupts (e.g. HAL_LPTIM_PWM_Start_IT()):
mbed_official 181:a4cbdfbbd2f4 28 (+) Configure the LPTIM interrupt priority using HAL_NVIC_SetPriority().
mbed_official 181:a4cbdfbbd2f4 29 (+) Enable the LPTIM IRQ handler using HAL_NVIC_EnableIRQ().
mbed_official 181:a4cbdfbbd2f4 30 (+) In LPTIM IRQ handler, call HAL_LPTIM_IRQHandler().
mbed_official 181:a4cbdfbbd2f4 31
mbed_official 181:a4cbdfbbd2f4 32 (#)Initialize the LPTIM HAL using HAL_LPTIM_Init(). This function
mbed_official 181:a4cbdfbbd2f4 33 configures mainly:
mbed_official 181:a4cbdfbbd2f4 34 (##) The instance: Only LPTIM1 is present in STM32L053xx.
mbed_official 181:a4cbdfbbd2f4 35 (##) Clock: the counter clock.
mbed_official 181:a4cbdfbbd2f4 36 - Source : it can be either the ULPTIM input (IN1) or one of
mbed_official 181:a4cbdfbbd2f4 37 the internal clock; (APB, LSE, LSI or MSI).
mbed_official 181:a4cbdfbbd2f4 38 - Prescaler: select the clock divider.
mbed_official 181:a4cbdfbbd2f4 39 (##) UltraLowPowerClock : To be used only if the ULPTIM is selected
mbed_official 181:a4cbdfbbd2f4 40 as counter clock source.
mbed_official 181:a4cbdfbbd2f4 41 - Polarity: polarity of the active edge for the counter unit
mbed_official 181:a4cbdfbbd2f4 42 if the ULPTIM input is selected.
mbed_official 181:a4cbdfbbd2f4 43 - SampleTime: clock sampling time to configure the clock glitch
mbed_official 181:a4cbdfbbd2f4 44 filter.
mbed_official 181:a4cbdfbbd2f4 45 (##) Trigger: How the counter start.
mbed_official 181:a4cbdfbbd2f4 46 - Source: trigger can be software or one of the hardware triggers.
mbed_official 181:a4cbdfbbd2f4 47 - ActiveEdge : only for hardware trigger.
mbed_official 181:a4cbdfbbd2f4 48 - SampleTime : trigger sampling time to configure the trigger
mbed_official 181:a4cbdfbbd2f4 49 glitch filter.
mbed_official 181:a4cbdfbbd2f4 50 (##) OutputPolarity : 2 opposite polarities are possibles.
mbed_official 181:a4cbdfbbd2f4 51 (##) UpdateMode: specifies whether the update of the autoreload and
mbed_official 181:a4cbdfbbd2f4 52 the compare values is done immediately or after the end of current
mbed_official 181:a4cbdfbbd2f4 53 period.
mbed_official 181:a4cbdfbbd2f4 54
mbed_official 181:a4cbdfbbd2f4 55 (#)Six modes are available:
mbed_official 181:a4cbdfbbd2f4 56
mbed_official 181:a4cbdfbbd2f4 57 (##) PWM Mode: To generate a PWM signal with specified period and pulse,
mbed_official 181:a4cbdfbbd2f4 58 call HAL_LPTIM_PWM_Start() or HAL_LPTIM_PWM_Start_IT() for interruption
mbed_official 181:a4cbdfbbd2f4 59 mode.
mbed_official 181:a4cbdfbbd2f4 60
mbed_official 181:a4cbdfbbd2f4 61 (##) One Pulse Mode: To generate pulse with specified width in response
mbed_official 181:a4cbdfbbd2f4 62 to a stimulus, call HAL_LPTIM_OnePulse_Start() or
mbed_official 181:a4cbdfbbd2f4 63 HAL_LPTIM_OnePulse_Start_IT() for interruption mode.
mbed_official 181:a4cbdfbbd2f4 64
mbed_official 181:a4cbdfbbd2f4 65 (##) Set once Mode: In this mode, the output changes the level (from
mbed_official 181:a4cbdfbbd2f4 66 low level to high level if the output polarity is configured high, else
mbed_official 181:a4cbdfbbd2f4 67 the opposite) when a compare match occurs. To start this mode, call
mbed_official 181:a4cbdfbbd2f4 68 HAL_LPTIM_SetOnce_Start() or HAL_LPTIM_SetOnce_Start_IT() for
mbed_official 181:a4cbdfbbd2f4 69 interruption mode.
mbed_official 181:a4cbdfbbd2f4 70
mbed_official 181:a4cbdfbbd2f4 71 (##) Encoder Mode: To use the encoder interface call
mbed_official 181:a4cbdfbbd2f4 72 HAL_LPTIM_Encoder_Start() or HAL_LPTIM_Encoder_Start_IT() for
mbed_official 181:a4cbdfbbd2f4 73 interruption mode.
mbed_official 181:a4cbdfbbd2f4 74
mbed_official 181:a4cbdfbbd2f4 75 (##) Time out Mode: an active edge on one selected trigger input rests
mbed_official 181:a4cbdfbbd2f4 76 the counter. The first trigger event will start the timer, any
mbed_official 181:a4cbdfbbd2f4 77 successive trigger event will reset the counter and the timer will
mbed_official 181:a4cbdfbbd2f4 78 restart. To start this mode call HAL_LPTIM_TimeOut_Start_IT() or
mbed_official 181:a4cbdfbbd2f4 79 HAL_LPTIM_TimeOut_Start_IT() for interruption mode.
mbed_official 181:a4cbdfbbd2f4 80
mbed_official 181:a4cbdfbbd2f4 81 (##) Counter Mode: counter can be used to count external events on
mbed_official 181:a4cbdfbbd2f4 82 the LPTIM Input1 or it can be used to count internal clock cycles.
mbed_official 181:a4cbdfbbd2f4 83 To start this mode, call HAL_LPTIM_Counter_Start() or
mbed_official 181:a4cbdfbbd2f4 84 HAL_LPTIM_Counter_Start_IT() for interruption mode.
mbed_official 181:a4cbdfbbd2f4 85
mbed_official 181:a4cbdfbbd2f4 86
mbed_official 181:a4cbdfbbd2f4 87 (#) User can stop any process by calling the corresponding API:
mbed_official 181:a4cbdfbbd2f4 88 HAL_LPTIM_Xxx_Stop() or HAL_LPTIM_Xxx_Stop_IT() if the process is
mbed_official 181:a4cbdfbbd2f4 89 already started in interruption mode.
mbed_official 181:a4cbdfbbd2f4 90
mbed_official 181:a4cbdfbbd2f4 91 (#)Call HAL_LPTIM_DeInit() to deinitialize the LPTIM peripheral.
