****************************************************************************** + * @file stm32f4xx_hal_i2s.c + * @author MCD Application Team + * @brief I2S HAL module driver. + * This file provides firmware functions to manage the following + * functionalities of the Integrated Interchip Sound (I2S) peripheral: + * + Initialization and de-initialization functions + * + IO operation functions + * + Peripheral State and Errors functions + @verbatim + =============================================================================== + ##### How to use this driver ##### + =============================================================================== + [..] + The I2S HAL driver can be used as follow: + + (#) Declare a I2S_HandleTypeDef handle structure. + (#) Initialize the I2S low level resources by implement the HAL_I2S_MspInit() API: + (##) Enable the SPIx interface clock. + (##) I2S pins configuration: + (+++) Enable the clock for the I2S GPIOs. + (+++) Configure these I2S pins as alternate function pull-up. + (##) NVIC configuration if you need to use interrupt process (HAL_I2S_Transmit_IT() + and HAL_I2S_Receive_IT() APIs). + (+++) Configure the I2Sx interrupt priority. + (+++) Enable the NVIC I2S IRQ handle. + (##) DMA Configuration if you need to use DMA process (HAL_I2S_Transmit_DMA() + and HAL_I2S_Receive_DMA() APIs: + (+++) Declare a DMA handle structure for the Tx/Rx Stream/Channel. + (+++) Enable the DMAx interface clock. + (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters. + (+++) Configure the DMA Tx/Rx Stream/Channel. + (+++) Associate the initialized DMA handle to the I2S DMA Tx/Rx handle. + (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the + DMA Tx/Rx Stream/Channel. + + (#) Program the Mode, Standard, Data Format, MCLK Output, Audio frequency and Polarity + using HAL_I2S_Init() function. + + -@- The specific I2S interrupts (Transmission complete interrupt, + RXNE interrupt and Error Interrupts) will be managed using the macros + __HAL_I2S_ENABLE_IT() and __HAL_I2S_DISABLE_IT() inside the transmit and receive process. + -@- Make sure that either: + (+@) I2S PLL clock is configured or + (+@) External clock source is configured after setting correctly + the define constant EXTERNAL_CLOCK_VALUE in the stm32f4xx_hal_conf.h file. + + (#) Three mode of operations are available within this driver : + + *** Polling mode IO operation *** + ================================= + [..] + (+) Send an amount of data in blocking mode using

HAL_I2S_DMAResume() + (+) Stop the DMA Transfer using HAL_I2S_DMAStop() + + *** I2S HAL driver macros list *** + =================================== + [..] + Below the list of most used macros in I2S HAL driver. + + (+) __HAL_I2S_ENABLE: Enable the specified SPI peripheral (in I2S mode) + (+) __HAL_I2S_DISABLE: Disable the specified SPI peripheral (in I2S mode) + (+) __HAL_I2S_ENABLE_IT : Enable the specified I2S interrupts + (+) __HAL_I2S_DISABLE_IT : Disable the specified I2S interrupts + (+) __HAL_I2S_GET_FLAG: Check whether the specified I2S flag is set or not + + [..] + (@) You can refer to the I2S HAL driver header file for more useful macros + + *** I2S HAL driver macros list *** + =================================== + [..] + Callback registration: + + (#) The compilation flag USE_HAL_I2S_REGISTER_CALLBACKS when set to 1U + allows the user to configure dynamically the driver callbacks. + Use Functions HAL_I2S_RegisterCallback() to register an interrupt callback. + + Function HAL_I2S_RegisterCallback() allows to register following callbacks: + (+) TxCpltCallback : I2S Tx Completed callback + (+) RxCpltCallback : I2S Rx Completed callback + (+) TxRxCpltCallback : I2S TxRx Completed callback + (+) TxHalfCpltCallback : I2S Tx Half Completed callback + (+) RxHalfCpltCallback : I2S Rx Half Completed callback + (+) ErrorCallback : I2S Error callback + (+) MspInitCallback : I2S Msp Init callback + (+) MspDeInitCallback : I2S 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_I2S_UnRegisterCallback to reset a callback to the default + weak function. + HAL_I2S_UnRegisterCallback takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxCpltCallback : I2S Tx Completed callback + (+) RxCpltCallback : I2S Rx Completed callback + (+) TxRxCpltCallback : I2S TxRx Completed callback + (+) TxHalfCpltCallback : I2S Tx Half Completed callback + (+) RxHalfCpltCallback : I2S Rx Half Completed callback + (+) ErrorCallback : I2S Error callback + (+) MspInitCallback : I2S Msp Init callback + (+) MspDeInitCallback : I2S Msp DeInit callback + + By default, after the HAL_I2S_Init() and when the state is HAL_I2S_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples HAL_I2S_MasterTxCpltCallback(), HAL_I2S_MasterRxCpltCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak functions in the HAL_I2S_Init()/ HAL_I2S_DeInit() only when + these callbacks are null (not registered beforehand). + If MspInit or MspDeInit are not null, the HAL_I2S_Init()/ HAL_I2S_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state. + + Callbacks can be registered/unregistered in HAL_I2S_STATE_READY state only. + Exception done MspInit/MspDeInit functions that can be registered/unregistered + in HAL_I2S_STATE_READY or HAL_I2S_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_I2S_RegisterCallback() before calling HAL_I2S_DeInit() + or HAL_I2S_Init() function. + + When The compilation define USE_HAL_I2S_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registering feature is not available + and weak (surcharged) callbacks are used. + + @endverbatim +
