NYX 0:85b3fd62ea1a 17 ##### How to use this driver #####
NYX 0:85b3fd62ea1a 18 ==============================================================================
NYX 0:85b3fd62ea1a 19
NYX 0:85b3fd62ea1a 20 [..]
NYX 0:85b3fd62ea1a 21 The SAI HAL driver can be used as follows:
NYX 0:85b3fd62ea1a 22
NYX 0:85b3fd62ea1a 23 (#) Declare a SAI_HandleTypeDef handle structure (eg. SAI_HandleTypeDef hsai).
NYX 0:85b3fd62ea1a 24 (#) Initialize the SAI low level resources by implementing the HAL_SAI_MspInit() API:
NYX 0:85b3fd62ea1a 25 (##) Enable the SAI interface clock.
NYX 0:85b3fd62ea1a 26 (##) SAI pins configuration:
NYX 0:85b3fd62ea1a 27 (+++) Enable the clock for the SAI GPIOs.
NYX 0:85b3fd62ea1a 28 (+++) Configure these SAI pins as alternate function pull-up.
NYX 0:85b3fd62ea1a 29 (##) NVIC configuration if you need to use interrupt process (HAL_SAI_Transmit_IT()
NYX 0:85b3fd62ea1a 30 and HAL_SAI_Receive_IT() APIs):
NYX 0:85b3fd62ea1a 31 (+++) Configure the SAI interrupt priority.
NYX 0:85b3fd62ea1a 32 (+++) Enable the NVIC SAI IRQ handle.
NYX 0:85b3fd62ea1a 33
NYX 0:85b3fd62ea1a 34 (##) DMA Configuration if you need to use DMA process (HAL_SAI_Transmit_DMA()
NYX 0:85b3fd62ea1a 35 and HAL_SAI_Receive_DMA() APIs):
NYX 0:85b3fd62ea1a 36 (+++) Declare a DMA handle structure for the Tx/Rx stream.
NYX 0:85b3fd62ea1a 37 (+++) Enable the DMAx interface clock.
NYX 0:85b3fd62ea1a 38 (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters.
NYX 0:85b3fd62ea1a 39 (+++) Configure the DMA Tx/Rx Stream.
NYX 0:85b3fd62ea1a 40 (+++) Associate the initialized DMA handle to the SAI DMA Tx/Rx handle.
NYX 0:85b3fd62ea1a 41 (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the
NYX 0:85b3fd62ea1a 42 DMA Tx/Rx Stream.
NYX 0:85b3fd62ea1a 43
NYX 0:85b3fd62ea1a 44 (#) The initialization can be done by two ways
NYX 0:85b3fd62ea1a 45 (##) Expert mode : Initialize the structures Init, FrameInit and SlotInit and call HAL_SAI_Init().
NYX 0:85b3fd62ea1a 46 (##) Simplified mode : Initialize the high part of Init Structure and call HAL_SAI_InitProtocol().
NYX 0:85b3fd62ea1a 47
NYX 0:85b3fd62ea1a 48 [..]
NYX 0:85b3fd62ea1a 49 (@) The specific SAI interrupts (FIFO request and Overrun underrun interrupt)
NYX 0:85b3fd62ea1a 50 will be managed using the macros __HAL_SAI_ENABLE_IT() and __HAL_SAI_DISABLE_IT()
NYX 0:85b3fd62ea1a 51 inside the transmit and receive process.
NYX 0:85b3fd62ea1a 52
NYX 0:85b3fd62ea1a 53 [..]
NYX 0:85b3fd62ea1a 54 (@) SAI Clock Source configuration is managed differently depending on the selected
NYX 0:85b3fd62ea1a 55 STM32F4 devices :
NYX 0:85b3fd62ea1a 56 (+@) For STM32F446xx devices, the configuration is managed through RCCEx_PeriphCLKConfig()
NYX 0:85b3fd62ea1a 57 function in the HAL RCC drivers
NYX 0:85b3fd62ea1a 58 (+@) For STM32F439xx/STM32F437xx/STM32F429xx/STM32F427xx devices, the configuration
NYX 0:85b3fd62ea1a 59 is managed within HAL SAI drivers through HAL_SAI_Init() function using
NYX 0:85b3fd62ea1a 60 ClockSource field of SAI_InitTypeDef structure.
NYX 0:85b3fd62ea1a 61 [..]
NYX 0:85b3fd62ea1a 62 (@) Make sure that either:
NYX 0:85b3fd62ea1a 63 (+@) I2S PLL is configured or
NYX 0:85b3fd62ea1a 64 (+@) SAI PLL is configured or
NYX 0:85b3fd62ea1a 65 (+@) External clock source is configured after setting correctly
NYX 0:85b3fd62ea1a 66 the define constant EXTERNAL_CLOCK_VALUE in the stm32f4xx_hal_conf.h file.
NYX 0:85b3fd62ea1a 67 [..]
NYX 0:85b3fd62ea1a 68 (@) In master Tx mode: enabling the audio block immediately generates the bit clock
NYX 0:85b3fd62ea1a 69 for the external slaves even if there is no data in the FIFO, However FS signal
NYX 0:85b3fd62ea1a 70 generation is conditioned by the presence of data in the FIFO.
NYX 0:85b3fd62ea1a 71
NYX 0:85b3fd62ea1a 72 [..]
NYX 0:85b3fd62ea1a 73 (@) In master Rx mode: enabling the audio block immediately generates the bit clock
NYX 0:85b3fd62ea1a 74 and FS signal for the external slaves.
NYX 0:85b3fd62ea1a 75
NYX 0:85b3fd62ea1a 76 [..]
NYX 0:85b3fd62ea1a 77 (@) It is mandatory to respect the following conditions in order to avoid bad SAI behavior:
NYX 0:85b3fd62ea1a 78 (+@) First bit Offset <= (SLOT size - Data size)
NYX 0:85b3fd62ea1a 79 (+@) Data size <= SLOT size
NYX 0:85b3fd62ea1a 80 (+@) Number of SLOT x SLOT size = Frame length
NYX 0:85b3fd62ea1a 81 (+@) The number of slots should be even when SAI_FS_CHANNEL_IDENTIFICATION is selected.
NYX 0:85b3fd62ea1a 82
NYX 0:85b3fd62ea1a 83 [..]
NYX 0:85b3fd62ea1a 84 Three operation modes are available within this driver :

NYX 0:85b3fd62ea1a 261
NYX 0:85b3fd62ea1a 262 (+) User must implement HAL_SAI_MspInit() function in which he configures
NYX 0:85b3fd62ea1a 263 all related peripherals resources (CLOCK, GPIO, DMA, IT and NVIC ).
NYX 0:85b3fd62ea1a 264
NYX 0:85b3fd62ea1a 265 (+) Call the function HAL_SAI_Init() to configure the selected device with
NYX 0:85b3fd62ea1a 266 the selected configuration:
NYX 0:85b3fd62ea1a 267 (++) Mode (Master/slave TX/RX)
NYX 0:85b3fd62ea1a 268 (++) Protocol
NYX 0:85b3fd62ea1a 269 (++) Data Size
NYX 0:85b3fd62ea1a 270 (++) MCLK Output
NYX 0:85b3fd62ea1a 271 (++) Audio frequency
NYX 0:85b3fd62ea1a 272 (++) FIFO Threshold
NYX 0:85b3fd62ea1a 273 (++) Frame Config
NYX 0:85b3fd62ea1a 274 (++) Slot Config
NYX 0:85b3fd62ea1a 275
NYX 0:85b3fd62ea1a 276 (+) Call the function HAL_SAI_DeInit() to restore the default configuration
NYX 0:85b3fd62ea1a 277 of the selected SAI peripheral.

NYX 0:85b3fd62ea1a 583 [..]
NYX 0:85b3fd62ea1a 584 This subsection provides a set of functions allowing to manage the SAI data
NYX 0:85b3fd62ea1a 585 transfers.
NYX 0:85b3fd62ea1a 586
NYX 0:85b3fd62ea1a 587 (+) There are two modes of transfer:
NYX 0:85b3fd62ea1a 588 (++) Blocking mode : The communication is performed in the polling mode.
NYX 0:85b3fd62ea1a 589 The status of all data processing is returned by the same function
NYX 0:85b3fd62ea1a 590 after finishing transfer.
NYX 0:85b3fd62ea1a 591 (++) No-Blocking mode : The communication is performed using Interrupts
NYX 0:85b3fd62ea1a 592 or DMA. These functions return the status of the transfer startup.
NYX 0:85b3fd62ea1a 593 The end of the data processing will be indicated through the
NYX 0:85b3fd62ea1a 594 dedicated SAI IRQ when using Interrupt mode or the DMA IRQ when
NYX 0:85b3fd62ea1a 595 using DMA mode.
NYX 0:85b3fd62ea1a 596
NYX 0:85b3fd62ea1a 597 (+) Blocking mode functions are :
NYX 0:85b3fd62ea1a 598 (++) HAL_SAI_Transmit()
NYX 0:85b3fd62ea1a 599 (++) HAL_SAI_Receive()
NYX 0:85b3fd62ea1a 600 (++) HAL_SAI_TransmitReceive()
NYX 0:85b3fd62ea1a 601
NYX 0:85b3fd62ea1a 602 (+) Non Blocking mode functions with Interrupt are :
NYX 0:85b3fd62ea1a 603 (++) HAL_SAI_Transmit_IT()
NYX 0:85b3fd62ea1a 604 (++) HAL_SAI_Receive_IT()
NYX 0:85b3fd62ea1a 605 (++) HAL_SAI_TransmitReceive_IT()
NYX 0:85b3fd62ea1a 606
NYX 0:85b3fd62ea1a 607 (+) Non Blocking mode functions with DMA are :
NYX 0:85b3fd62ea1a 608 (++) HAL_SAI_Transmit_DMA()
NYX 0:85b3fd62ea1a 609 (++) HAL_SAI_Receive_DMA()
NYX 0:85b3fd62ea1a 610 (++) HAL_SAI_TransmitReceive_DMA()
NYX 0:85b3fd62ea1a 611
NYX 0:85b3fd62ea1a 612 (+) A set of Transfer Complete Callbacks are provided in non Blocking mode:
NYX 0:85b3fd62ea1a 613 (++) HAL_SAI_TxCpltCallback()
NYX 0:85b3fd62ea1a 614 (++) HAL_SAI_RxCpltCallback()
NYX 0:85b3fd62ea1a 615 (++) HAL_SAI_ErrorCallback()
