| 15 | ##### How to use this driver ##### |
| 16 | ============================================================================== |
| 17 | |
| 18 | [..] |
| 19 | The SAI HAL driver can be used as follows: |
| 20 | |
| 21 | (#) Declare a SAI_HandleTypeDef handle structure (eg. SAI_HandleTypeDef hsai). |
| 22 | (#) Initialize the SAI low level resources by implementing the HAL_SAI_MspInit() API: |
| 23 | (##) Enable the SAI interface clock. |
| 24 | (##) SAI pins configuration: |
| 25 | (+++) Enable the clock for the SAI GPIOs. |
| 26 | (+++) Configure these SAI pins as alternate function pull-up. |
| 27 | (##) NVIC configuration if you need to use interrupt process (HAL_SAI_Transmit_IT() |
| 28 | and HAL_SAI_Receive_IT() APIs): |
| 29 | (+++) Configure the SAI interrupt priority. |
| 30 | (+++) Enable the NVIC SAI IRQ handle. |
| 31 | |
| 32 | (##) DMA Configuration if you need to use DMA process (HAL_SAI_Transmit_DMA() |
| 33 | and HAL_SAI_Receive_DMA() APIs): |
| 34 | (+++) Declare a DMA handle structure for the Tx/Rx stream. |
| 35 | (+++) Enable the DMAx interface clock. |
| 36 | (+++) Configure the declared DMA handle structure with the required Tx/Rx parameters. |
| 37 | (+++) Configure the DMA Tx/Rx Stream. |
| 38 | (+++) Associate the initialized DMA handle to the SAI DMA Tx/Rx handle. |
| 39 | (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on the |
| 40 | DMA Tx/Rx Stream. |
| 41 | |
| 42 | (#) The initialization can be done by two ways |
| 43 | (##) Expert mode : Initialize the structures Init, FrameInit and SlotInit and call HAL_SAI_Init(). |
| 44 | (##) Simplified mode : Initialize the high part of Init Structure and call HAL_SAI_InitProtocol(). |
| 45 | |
| 46 | [..] |
| 47 | (@) The specific SAI interrupts (FIFO request and Overrun underrun interrupt) |
| 48 | will be managed using the macros __HAL_SAI_ENABLE_IT() and __HAL_SAI_DISABLE_IT() |
| 49 | inside the transmit and receive process. |
| 50 | [..] |
| 51 | (@) Make sure that SAI clock source is configured: |
| 52 | (+@) SYSCLK or |
| 53 | (+@) PLLQ output or |
| 54 | (+@) HSI or |
| 55 | (+@) External clock source which is configured after setting correctly |
| 56 | the define constant EXTERNAL_CLOCK_VALUE in the stm32g4xx_hal_conf.h file. |
| 57 | |
| 58 | [..] |
| 59 | (@) In master Tx mode: enabling the audio block immediately generates the bit clock |
| 60 | for the external slaves even if there is no data in the FIFO, However FS signal |
| 61 | generation is conditioned by the presence of data in the FIFO. |
| 62 | |
| 63 | [..] |
| 64 | (@) In master Rx mode: enabling the audio block immediately generates the bit clock |
| 65 | and FS signal for the external slaves. |
| 66 | |
| 67 | [..] |
| 68 | (@) It is mandatory to respect the following conditions in order to avoid bad SAI behavior: |
| 69 | (+@) First bit Offset <= (SLOT size - Data size) |
| 70 | (+@) Data size <= SLOT size |
| 71 | (+@) Number of SLOT x SLOT size = Frame length |
| 72 | (+@) The number of slots should be even when SAI_FS_CHANNEL_IDENTIFICATION is selected. |
| 73 | |
| 74 | [..] |
| 75 | (@) PDM interface can be activated through HAL_SAI_Init function. |
| 76 | Please note that PDM interface is only available for SAI1 sub-block A. |
| 77 | PDM microphone delays can be tuned with HAL_SAIEx_ConfigPdmMicDelay function. |
| 78 | |
| 79 | [..] |

| 905 | ##### IO operation functions ##### |
| 906 | ============================================================================== |
| 907 | [..] |
| 908 | This subsection provides a set of functions allowing to manage the SAI data |
| 909 | transfers. |
| 910 | |
| 911 | (+) There are two modes of transfer: |
| 912 | (++) Blocking mode : The communication is performed in the polling mode. |
| 913 | The status of all data processing is returned by the same function |
| 914 | after finishing transfer. |
| 915 | (++) No-Blocking mode : The communication is performed using Interrupts |
| 916 | or DMA. These functions return the status of the transfer startup. |
| 917 | The end of the data processing will be indicated through the |
| 918 | dedicated SAI IRQ when using Interrupt mode or the DMA IRQ when |
| 919 | using DMA mode. |
| 920 | |
| 921 | (+) Blocking mode functions are : |
| 922 | (++) HAL_SAI_Transmit() |
| 923 | (++) HAL_SAI_Receive() |
| 924 | |
| 925 | (+) Non Blocking mode functions with Interrupt are : |
| 926 | (++) HAL_SAI_Transmit_IT() |
| 927 | (++) HAL_SAI_Receive_IT() |
| 928 | |
| 929 | (+) Non Blocking mode functions with DMA are : |
| 930 | (++) HAL_SAI_Transmit_DMA() |
| 931 | (++) HAL_SAI_Receive_DMA() |
| 932 | |
| 933 | (+) A set of Transfer Complete Callbacks are provided in non Blocking mode: |
| 934 | (++) HAL_SAI_TxCpltCallback() |
| 935 | (++) HAL_SAI_RxCpltCallback() |
| 936 | (++) HAL_SAI_ErrorCallback() |
