- *** 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 - (+) 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 - ****************************************************************************** -
