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 + (+) InjectedConvCpltCallback : ADC group injected conversion complete 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 + (+) InjectedConvCpltCallback : ADC group injected conversion complete 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. + + @endverbatim +
