- ##### How to use this driver #####
- ==============================================================================
- [..]
-
- *** Configuration of top level parameters related to ADC ***
- ============================================================
- [..]
-
- (#) Enable the ADC interface
- (++) As prerequisite, ADC clock must be configured at RCC top level.
- Caution: On STM32F0, ADC clock frequency max is 14MHz (refer
- to device datasheet).
- Therefore, ADC clock prescaler must be configured in
- function of ADC clock source frequency to remain below
- this maximum frequency.
-
- (++) Two clock settings are mandatory:
- (+++) ADC clock (core clock, also possibly conversion clock).
-
- (+++) ADC clock (conversions clock).
- Two possible clock sources: synchronous clock derived from APB clock
- or asynchronous clock derived from ADC dedicated HSI RC oscillator
- 14MHz.
- If asynchronous clock is selected, parameter "HSI14State" must be set either:
- - to "...HSI14State = RCC_HSI14_ADC_CONTROL" to let the ADC control
- the HSI14 oscillator enable/disable (if not used to supply the main
- system clock): feature used if ADC mode LowPowerAutoPowerOff is
- enabled.
- - to "...HSI14State = RCC_HSI14_ON" to maintain the HSI14 oscillator
- always enabled: can be used to supply the main system clock.
-
- (+++) Example:
- Into HAL_ADC_MspInit() (recommended code location) or with
- other device clock parameters configuration:
- (+++) __HAL_RCC_ADC1_CLK_ENABLE(); (mandatory)
-
- HI14 enable or let under control of ADC: (optional: if asynchronous clock selected)
- (+++) RCC_OscInitTypeDef RCC_OscInitStructure;
- (+++) RCC_OscInitStructure.OscillatorType = RCC_OSCILLATORTYPE_HSI14;
- (+++) RCC_OscInitStructure.HSI14CalibrationValue = RCC_HSI14CALIBRATION_DEFAULT;
- (+++) RCC_OscInitStructure.HSI14State = RCC_HSI14_ADC_CONTROL;
- (+++) RCC_OscInitStructure.PLL... (optional if used for system clock)
- (+++) HAL_RCC_OscConfig(&RCC_OscInitStructure);
-
- (++) ADC clock source and clock prescaler are configured at ADC level with
- parameter "ClockPrescaler" using function HAL_ADC_Init().
-
- (#) ADC pins configuration
- (++) Enable the clock for the ADC GPIOs
- using macro __HAL_RCC_GPIOx_CLK_ENABLE()
- (++) Configure these ADC pins in analog mode
- using function HAL_GPIO_Init()
-
- (#) Optionally, in case of usage of ADC with interruptions:
- (++) Configure the NVIC for ADC
- using function HAL_NVIC_EnableIRQ(ADCx_IRQn)
- (++) Insert the ADC interruption handler function HAL_ADC_IRQHandler()
- into the function of corresponding ADC interruption vector
- ADCx_IRQHandler().
-
- (#) Optionally, in case of usage of DMA:
- (++) Configure the DMA (DMA channel, mode normal or circular, ...)
- using function HAL_DMA_Init().
- (++) Configure the NVIC for DMA
- using function HAL_NVIC_EnableIRQ(DMAx_Channelx_IRQn)
- (++) Insert the ADC interruption handler function HAL_ADC_IRQHandler()
- into the function of corresponding DMA interruption vector
- DMAx_Channelx_IRQHandler().
-
- *** Configuration of ADC, group regular, channels parameters ***
- ================================================================
- [..]
-
- (#) Configure the ADC parameters (resolution, data alignment, ...)
- and regular group parameters (conversion trigger, sequencer, ...)
- using function HAL_ADC_Init().
-
- (#) Configure the channels for regular group parameters (channel number,
- channel rank into sequencer, ..., into regular group)
- using function HAL_ADC_ConfigChannel().
-
- (#) Optionally, configure the analog watchdog parameters (channels
- monitored, thresholds, ...)
- using function HAL_ADC_AnalogWDGConfig().
-
- *** Execution of ADC conversions ***
- ====================================
- [..]
-
- (#) Optionally, perform an automatic ADC calibration to improve the
- conversion accuracy
- using function HAL_ADCEx_Calibration_Start().
-
- (#) ADC driver can be used among three modes: polling, interruption,
- transfer by DMA.
-
- (++) ADC conversion by polling:
- (+++) Activate the ADC peripheral and start conversions
- using function HAL_ADC_Start()
- (+++) Wait for ADC conversion completion
- using function HAL_ADC_PollForConversion()
- (+++) Retrieve conversion results
- using function HAL_ADC_GetValue()
- (+++) Stop conversion and disable the ADC peripheral
- using function HAL_ADC_Stop()
-
- (++) ADC conversion by interruption:
- (+++) Activate the ADC peripheral and start conversions
- using function HAL_ADC_Start_IT()
- (+++) Wait for ADC conversion completion by call of function
- HAL_ADC_ConvCpltCallback()
- (this function must be implemented in user program)
- (+++) Retrieve conversion results
- using function HAL_ADC_GetValue()
- (+++) Stop conversion and disable the ADC peripheral
- using function HAL_ADC_Stop_IT()
-
- (++) ADC conversion with transfer by DMA:
- (+++) Activate the ADC peripheral and start conversions
- using function HAL_ADC_Start_DMA()
- (+++) Wait for ADC conversion completion by call of function
- HAL_ADC_ConvCpltCallback() or HAL_ADC_ConvHalfCpltCallback()
- (these functions must be implemented in user program)
- (+++) Conversion results are automatically transferred by DMA into
- destination variable address.
- (+++) Stop conversion and disable the ADC peripheral
- using function HAL_ADC_Stop_DMA()
-
- [..]
-
- (@) Callback functions must be implemented in user program:
- (+@) HAL_ADC_ErrorCallback()
- (+@) HAL_ADC_LevelOutOfWindowCallback() (callback of analog watchdog)
- (+@) HAL_ADC_ConvCpltCallback()
- (+@) HAL_ADC_ConvHalfCpltCallback
-
- *** Deinitialization of ADC ***
- ============================================================
- [..]
-
- (#) Disable the ADC interface
- (++) ADC clock can be hard reset and disabled at RCC top level.
- (++) Hard reset of ADC peripherals
- using macro __ADCx_FORCE_RESET(), __ADCx_RELEASE_RESET().
- (++) ADC clock disable
- using the equivalent macro/functions as configuration step.
- (+++) Example:
- Into HAL_ADC_MspDeInit() (recommended code location) or with
- other device clock parameters configuration:
- (+++) RCC_OscInitStructure.OscillatorType = RCC_OSCILLATORTYPE_HSI14;
- (+++) RCC_OscInitStructure.HSI14State = RCC_HSI14_OFF; (if not used for system clock)
- (+++) HAL_RCC_OscConfig(&RCC_OscInitStructure);
-
- (#) ADC pins configuration
- (++) Disable the clock for the ADC GPIOs
- using macro __HAL_RCC_GPIOx_CLK_DISABLE()
-
- (#) Optionally, in case of usage of ADC with interruptions:
- (++) Disable the NVIC for ADC
- using function HAL_NVIC_DisableIRQ(ADCx_IRQn)
-
- (#) Optionally, in case of usage of DMA:
- (++) Deinitialize the DMA
- using function HAL_DMA_DeInit().
- (++) Disable the NVIC for DMA
- using function HAL_NVIC_DisableIRQ(DMAx_Channelx_IRQn)
-
- [..]
-
- *** Callback registration ***
- =============================================
- [..]
-
- The compilation flag USE_HAL_ADC_REGISTER_CALLBACKS, when set to 1,
- allows the user to configure dynamically the driver callbacks.
- Use Functions @ref HAL_ADC_RegisterCallback()
- to register an interrupt callback.
- [..]
-
- Function @ref HAL_ADC_RegisterCallback() allows to register following callbacks:
- (+) ConvCpltCallback : ADC conversion complete callback
- (+) ConvHalfCpltCallback : ADC conversion DMA half-transfer callback
- (+) LevelOutOfWindowCallback : ADC analog watchdog 1 callback
- (+) ErrorCallback : ADC error callback
- (+) MspInitCallback : ADC Msp Init callback
- (+) MspDeInitCallback : ADC Msp DeInit callback
- This function takes as parameters the HAL peripheral handle, the Callback ID
- and a pointer to the user callback function.
- [..]
-
- Use function @ref HAL_ADC_UnRegisterCallback to reset a callback to the default
- weak function.
- [..]
-
- @ref HAL_ADC_UnRegisterCallback takes as parameters the HAL peripheral handle,
- and the Callback ID.
- This function allows to reset following callbacks:
- (+) ConvCpltCallback : ADC conversion complete callback
- (+) ConvHalfCpltCallback : ADC conversion DMA half-transfer callback
- (+) LevelOutOfWindowCallback : ADC analog watchdog 1 callback
- (+) ErrorCallback : ADC error callback
- (+) MspInitCallback : ADC Msp Init callback
- (+) MspDeInitCallback : ADC Msp DeInit callback
- [..]
-
- By default, after the @ref HAL_ADC_Init() and when the state is @ref HAL_ADC_STATE_RESET
- all callbacks are set to the corresponding weak functions:
- examples @ref HAL_ADC_ConvCpltCallback(), @ref HAL_ADC_ErrorCallback().
- Exception done for MspInit and MspDeInit functions that are
- reset to the legacy weak functions in the @ref HAL_ADC_Init()/ @ref HAL_ADC_DeInit() only when
- these callbacks are null (not registered beforehand).
- [..]
-
- If MspInit or MspDeInit are not null, the @ref HAL_ADC_Init()/ @ref HAL_ADC_DeInit()
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
- [..]
-
- Callbacks can be registered/unregistered in @ref HAL_ADC_STATE_READY state only.
- Exception done MspInit/MspDeInit functions that can be registered/unregistered
- in @ref HAL_ADC_STATE_READY or @ref HAL_ADC_STATE_RESET state,
- thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
- [..]
-
- Then, the user first registers the MspInit/MspDeInit user callbacks
- using @ref HAL_ADC_RegisterCallback() before calling @ref HAL_ADC_DeInit()
- or @ref HAL_ADC_Init() function.
- [..]
-
- When the compilation flag USE_HAL_ADC_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.
