****************************************************************************** - * @file stm32f0xx_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: - (+@) External clock source is configured after setting correctly - the define constant EXTERNAL_CLOCK_VALUE in the stm32f0xx_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_Transmit() - (+) Receive an amount of data in blocking mode using HAL_I2S_Receive() - - *** Interrupt mode IO operation *** - =================================== - [..] - (+) Send an amount of data in non blocking mode using HAL_I2S_Transmit_IT() - (+) At transmission end of half transfer HAL_I2S_TxHalfCpltCallback is executed and user can - add his own code by customization of function pointer HAL_I2S_TxHalfCpltCallback - (+) At transmission end of transfer HAL_I2S_TxCpltCallback is executed and user can - add his own code by customization of function pointer HAL_I2S_TxCpltCallback - (+) Receive an amount of data in non blocking mode using HAL_I2S_Receive_IT() - (+) At reception end of half transfer HAL_I2S_RxHalfCpltCallback is executed and user can - add his own code by customization of function pointer HAL_I2S_RxHalfCpltCallback - (+) At reception end of transfer HAL_I2S_RxCpltCallback is executed and user can - add his own code by customization of function pointer HAL_I2S_RxCpltCallback - (+) In case of transfer Error, HAL_I2S_ErrorCallback() function is executed and user can - add his own code by customization of function pointer HAL_I2S_ErrorCallback - - *** DMA mode IO operation *** - ============================== - [..] - (+) Send an amount of data in non blocking mode (DMA) using HAL_I2S_Transmit_DMA() - (+) At transmission end of half transfer HAL_I2S_TxHalfCpltCallback is executed and user can - add his own code by customization of function pointer HAL_I2S_TxHalfCpltCallback - (+) At transmission end of transfer HAL_I2S_TxCpltCallback is executed and user can - add his own code by customization of function pointer HAL_I2S_TxCpltCallback - (+) Receive an amount of data in non blocking mode (DMA) using HAL_I2S_Receive_DMA() - (+) At reception end of half transfer HAL_I2S_RxHalfCpltCallback is executed and user can - add his own code by customization of function pointer HAL_I2S_RxHalfCpltCallback - (+) At reception end of transfer HAL_I2S_RxCpltCallback is executed and user can - add his own code by customization of function pointer HAL_I2S_RxCpltCallback - (+) In case of transfer Error, HAL_I2S_ErrorCallback() function is executed and user can - add his own code by customization of function pointer HAL_I2S_ErrorCallback - (+) Pause the DMA Transfer using HAL_I2S_DMAPause() - (+) Resume the DMA Transfer 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 - (++) 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 - (++) 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 - ****************************************************************************** -
