+ ##### 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 AHB clock
+ or asynchronous clock derived from system clock, the PLL2 or the PLL3 running up to 400MHz.
+
+ (+++) Example:
+ Into HAL_ADC_MspInit() (recommended code location) or with
+ other device clock parameters configuration:
+ (+++) __HAL_RCC_ADC_CLK_ENABLE(); (mandatory)
+
+ RCC_ADCCLKSOURCE_PLL2 enable: (optional: if asynchronous clock selected)
+ (+++) RCC_PeriphClkInitTypeDef RCC_PeriphClkInit;
+ (+++) PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_ADC;
+ (+++) PeriphClkInit.AdcClockSelection = RCC_ADCCLKSOURCE_PLL2;
+ (+++) 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 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 __HAL_RCC_ADCx_FORCE_RESET(), __HAL_RCC_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:
+ (+++) __HAL_RCC_ADC_CLK_DISABLE(); (if not used anymore)
+ RCC_ADCCLKSOURCE_CLKP restore: (optional)
+ (+++) RCC_PeriphClkInitTypeDef RCC_PeriphClkInit;
+ (+++) PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_ADC;
+ (+++) PeriphClkInit.AdcClockSelection = RCC_ADCCLKSOURCE_CLKP;
+ (+++) HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit);
+
+ (#) 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.
