- ===============================================================================
- ##### 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.
