****************************************************************************** - * @file stm32f0xx_hal_cec.c - * @author MCD Application Team - * @brief CEC HAL module driver. - * This file provides firmware functions to manage the following - * functionalities of the High Definition Multimedia Interface - * Consumer Electronics Control Peripheral (CEC). - * + Initialization and de-initialization function - * + IO operation function - * + Peripheral Control function - * - * - @verbatim - =============================================================================== - ##### How to use this driver ##### - =============================================================================== - [..] - The CEC HAL driver can be used as follow: - - (#) Declare a CEC_HandleTypeDef handle structure. - (#) Initialize the CEC low level resources by implementing the HAL_CEC_MspInit ()API: - (##) Enable the CEC interface clock. - (##) CEC pins configuration: - (+++) Enable the clock for the CEC GPIOs. - (+++) Configure these CEC pins as alternate function pull-up. - (##) NVIC configuration if you need to use interrupt process (HAL_CEC_Transmit_IT() - and HAL_CEC_Receive_IT() APIs): - (+++) Configure the CEC interrupt priority. - (+++) Enable the NVIC CEC IRQ handle. - (+++) The specific CEC interrupts (Transmission complete interrupt, - RXNE interrupt and Error Interrupts) will be managed using the macros - __HAL_CEC_ENABLE_IT() and __HAL_CEC_DISABLE_IT() inside the transmit - and receive process. - - (#) Program the Signal Free Time (SFT) and SFT option, Tolerance, reception stop in - in case of Bit Rising Error, Error-Bit generation conditions, device logical - address and Listen mode in the hcec Init structure. - - (#) Initialize the CEC registers by calling the HAL_CEC_Init() API. - - [..] - (@) This API (HAL_CEC_Init()) configures also the low level Hardware (GPIO, CLOCK, CORTEX...etc) - by calling the customed HAL_CEC_MspInit() API. - *** Callback registration *** - ============================================= - - The compilation define USE_HAL_CEC_REGISTER_CALLBACKS when set to 1 - allows the user to configure dynamically the driver callbacks. - Use Functions @ref HAL_CEC_RegisterCallback() or HAL_CEC_RegisterXXXCallback() - to register an interrupt callback. - - Function @ref HAL_CEC_RegisterCallback() allows to register following callbacks: - (+) TxCpltCallback : Tx Transfer completed callback. - (+) ErrorCallback : callback for error detection. - (+) MspInitCallback : CEC MspInit. - (+) MspDeInitCallback : CEC MspDeInit. - This function takes as parameters the HAL peripheral handle, the Callback ID - and a pointer to the user callback function. - - For specific callback HAL_CEC_RxCpltCallback use dedicated register callbacks - @ref HAL_CEC_RegisterRxCpltCallback(). - - Use function @ref HAL_CEC_UnRegisterCallback() to reset a callback to the default - weak function. - @ref HAL_CEC_UnRegisterCallback() takes as parameters the HAL peripheral handle, - and the Callback ID. - This function allows to reset following callbacks: - (+) TxCpltCallback : Tx Transfer completed callback. - (+) ErrorCallback : callback for error detection. - (+) MspInitCallback : CEC MspInit. - (+) MspDeInitCallback : CEC MspDeInit. - - For callback HAL_CEC_RxCpltCallback use dedicated unregister callback : - @ref HAL_CEC_UnRegisterRxCpltCallback(). - - By default, after the @ref HAL_CEC_Init() and when the state is HAL_CEC_STATE_RESET - all callbacks are set to the corresponding weak functions : - examples @ref HAL_CEC_TxCpltCallback() , @ref HAL_CEC_RxCpltCallback(). - Exception done for MspInit and MspDeInit functions that are - reset to the legacy weak function in the @ref HAL_CEC_Init()/ @ref HAL_CEC_DeInit() only when - these callbacks are null (not registered beforehand). - if not, MspInit or MspDeInit are not null, the @ref HAL_CEC_Init() / @ref HAL_CEC_DeInit() - keep and use the user MspInit/MspDeInit functions (registered beforehand) - - Callbacks can be registered/unregistered in HAL_CEC_STATE_READY state only. - Exception done MspInit/MspDeInit callbacks that can be registered/unregistered - in HAL_CEC_STATE_READY or HAL_CEC_STATE_RESET state, - thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit. - In that case first register the MspInit/MspDeInit user callbacks - using @ref HAL_CEC_RegisterCallback() before calling @ref HAL_CEC_DeInit() - or @ref HAL_CEC_Init() function. - - When the compilation define USE_HAL_CEC_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 - ****************************************************************************** -
