- ##### 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.
- (++) 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 system clock, PLLSAI1 or the PLLSAI2
- running up to 80MHz.
- (+++) Example:
- Into HAL_ADC_MspInit() (recommended code location) or with
- other device clock parameters configuration:
- (+++) __HAL_RCC_ADC_CLK_ENABLE(); (mandatory)
- RCC_ADCCLKSOURCE_PLL enable: (optional: if asynchronous clock selected)
- (+++) RCC_PeriphClkInitTypeDef RCC_PeriphClkInit;
- (+++) PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_ADC;
- (+++) PeriphClkInit.AdcClockSelection = RCC_ADCCLKSOURCE_PLL;
- (+++) HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit);
- (++) 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 ADC parameters (resolution, data alignment, ...)
- and regular group parameters (conversion trigger, sequencer, ...)

- channel rank into sequencer, ..., into regular group)
- using function HAL_ADC_ConfigChannel().
- (#) Optionally, configure the analog watchdog parameters (channels
- monitored, thresholds, ...)

- *** 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:

- (++) 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_EnableIRQ(ADCx_IRQn)
- (#) Optionally, in case of usage of DMA:
- (++) Deinitialize the DMA
- using function HAL_DMA_Init().
- (++) Disable the NVIC for DMA
- using function HAL_NVIC_EnableIRQ(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 HAL_ADC_RegisterCallback()
- to register an interrupt callback.
- [..]
- Function 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
- (+) InjectedConvCpltCallback : ADC group injected conversion complete callback
- (+) InjectedQueueOverflowCallback : ADC group injected context queue overflow callback
- (+) LevelOutOfWindow2Callback : ADC analog watchdog 2 callback
- (+) LevelOutOfWindow3Callback : ADC analog watchdog 3 callback
- (+) EndOfSamplingCallback : ADC end of sampling 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 HAL_ADC_UnRegisterCallback to reset a callback to the default
- weak function.
- [..]
- 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
- (+) InjectedConvCpltCallback : ADC group injected conversion complete callback
- (+) InjectedQueueOverflowCallback : ADC group injected context queue overflow callback
- (+) LevelOutOfWindow2Callback : ADC analog watchdog 2 callback
- (+) LevelOutOfWindow3Callback : ADC analog watchdog 3 callback
- (+) EndOfSamplingCallback : ADC end of sampling callback
- (+) MspInitCallback : ADC Msp Init callback
- (+) MspDeInitCallback : ADC Msp DeInit callback
- [..]
- By default, after the HAL_ADC_Init() and when the state is HAL_ADC_STATE_RESET
- all callbacks are set to the corresponding weak functions:
- examples HAL_ADC_ConvCpltCallback(), HAL_ADC_ErrorCallback().
- Exception done for MspInit and MspDeInit functions that are
- reset to the legacy weak functions in the HAL_ADC_Init()/ HAL_ADC_DeInit() only when
- these callbacks are null (not registered beforehand).
- [..]
- If MspInit or MspDeInit are not null, the HAL_ADC_Init()/ HAL_ADC_DeInit()
- keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
- [..]
- Callbacks can be registered/unregistered in HAL_ADC_STATE_READY state only.
- Exception done MspInit/MspDeInit functions that can be registered/unregistered
- in HAL_ADC_STATE_READY or 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 HAL_ADC_RegisterCallback() before calling HAL_ADC_DeInit()
- or 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.
