Jerome Coutant 0:c0f3bbab73d2 7 * @brief This file provides the Audio driver for the STM32F769I-DISCOVERY
Jerome Coutant 0:c0f3bbab73d2 8 * board.
Jerome Coutant 0:c0f3bbab73d2 9 @verbatim
Jerome Coutant 0:c0f3bbab73d2 10 How To use this driver:
Jerome Coutant 0:c0f3bbab73d2 11 -----------------------
Jerome Coutant 0:c0f3bbab73d2 12 + This driver supports STM32F7xx devices on STM32F769I-DISCOVERY (MB1225) Evaluation boards.
Jerome Coutant 0:c0f3bbab73d2 13 + Call the function BSP_AUDIO_OUT_Init(
Jerome Coutant 0:c0f3bbab73d2 14 OutputDevice: physical output mode (OUTPUT_DEVICE_SPEAKER,
Jerome Coutant 0:c0f3bbab73d2 15 OUTPUT_DEVICE_HEADPHONE or OUTPUT_DEVICE_BOTH)
Jerome Coutant 0:c0f3bbab73d2 16 Volume : Initial volume to be set (0 is min (mute), 100 is max (100%)
Jerome Coutant 0:c0f3bbab73d2 17 AudioFreq : Audio frequency in Hz (8000, 16000, 22500, 32000...)
Jerome Coutant 0:c0f3bbab73d2 18 this parameter is relative to the audio file/stream type.
Jerome Coutant 0:c0f3bbab73d2 19 )
Jerome Coutant 0:c0f3bbab73d2 20 This function configures all the hardware required for the audio application (codec, I2C, SAI,
Jerome Coutant 0:c0f3bbab73d2 21 GPIOs, DMA and interrupt if needed). This function returns AUDIO_OK if configuration is OK.
Jerome Coutant 0:c0f3bbab73d2 22 If the returned value is different from AUDIO_OK or the function is stuck then the communication with
Jerome Coutant 0:c0f3bbab73d2 23 the codec has failed (try to un-plug the power or reset device in this case).
Jerome Coutant 0:c0f3bbab73d2 24 - OUTPUT_DEVICE_SPEAKER : only speaker will be set as output for the audio stream.
Jerome Coutant 0:c0f3bbab73d2 25 - OUTPUT_DEVICE_HEADPHONE: only headphones will be set as output for the audio stream.
Jerome Coutant 0:c0f3bbab73d2 26 - OUTPUT_DEVICE_BOTH : both Speaker and Headphone are used as outputs for the audio stream
Jerome Coutant 0:c0f3bbab73d2 27 at the same time.
Jerome Coutant 0:c0f3bbab73d2 28 Note. On STM32F769I-DISCOVERY SAI_DMA is configured in CIRCULAR mode. Due to this the application
Jerome Coutant 0:c0f3bbab73d2 29 does NOT need to call BSP_AUDIO_OUT_ChangeBuffer() to assure streaming.
Jerome Coutant 0:c0f3bbab73d2 30 + Call the function BSP_AUDIO_OUT_Play(
Jerome Coutant 0:c0f3bbab73d2 31 pBuffer: pointer to the audio data file address
Jerome Coutant 0:c0f3bbab73d2 32 Size : size of the buffer to be sent in Bytes
Jerome Coutant 0:c0f3bbab73d2 33 )
Jerome Coutant 0:c0f3bbab73d2 34 to start playing (for the first time) from the audio file/stream.
Jerome Coutant 0:c0f3bbab73d2 35 + Call the function BSP_AUDIO_OUT_Pause() to pause playing
Jerome Coutant 0:c0f3bbab73d2 36 + Call the function BSP_AUDIO_OUT_Resume() to resume playing.
Jerome Coutant 0:c0f3bbab73d2 37 Note. After calling BSP_AUDIO_OUT_Pause() function for pause, only BSP_AUDIO_OUT_Resume() should be called
Jerome Coutant 0:c0f3bbab73d2 38 for resume (it is not allowed to call BSP_AUDIO_OUT_Play() in this case).
Jerome Coutant 0:c0f3bbab73d2 39 Note. This function should be called only when the audio file is played or paused (not stopped).
Jerome Coutant 0:c0f3bbab73d2 40 + For each mode, you may need to implement the relative callback functions into your code.
Jerome Coutant 0:c0f3bbab73d2 41 The Callback functions are named BSP_AUDIO_OUT_XXX_CallBack() and only their prototypes are declared in
Jerome Coutant 0:c0f3bbab73d2 42 the stm32f769i_discovery_audio.h file. (refer to the example for more details on the callbacks implementations)
Jerome Coutant 0:c0f3bbab73d2 43 + To Stop playing, to modify the volume level, the frequency, the audio frame slot,
Jerome Coutant 0:c0f3bbab73d2 44 the device output mode the mute or the stop, use the functions: BSP_AUDIO_OUT_SetVolume(),
Jerome Coutant 0:c0f3bbab73d2 45 AUDIO_OUT_SetFrequency(), BSP_AUDIO_OUT_SetAudioFrameSlot(), BSP_AUDIO_OUT_SetOutputMode(),
Jerome Coutant 0:c0f3bbab73d2 46 BSP_AUDIO_OUT_SetMute() and BSP_AUDIO_OUT_Stop().
Jerome Coutant 0:c0f3bbab73d2 47
Jerome Coutant 0:c0f3bbab73d2 48 + Call the function BSP_AUDIO_IN_Init(
Jerome Coutant 0:c0f3bbab73d2 49 AudioFreq: Audio frequency in Hz (8000, 16000, 22500, 32000...)
Jerome Coutant 0:c0f3bbab73d2 50 this parameter is relative to the audio file/stream type.
Jerome Coutant 0:c0f3bbab73d2 51 BitRes: Bit resolution fixed to 16bit
Jerome Coutant 0:c0f3bbab73d2 52 ChnlNbr: Number of channel to be configured for the DFSDM peripheral
Jerome Coutant 0:c0f3bbab73d2 53 )
Jerome Coutant 0:c0f3bbab73d2 54 This function configures all the hardware required for the audio in application (DFSDM filters and channels,
Jerome Coutant 0:c0f3bbab73d2 55 Clock source for DFSDM periphiral, GPIOs, DMA and interrupt if needed).
Jerome Coutant 0:c0f3bbab73d2 56 This function returns AUDIO_OK if configuration is OK.If the returned value is different from AUDIO_OK then
Jerome Coutant 0:c0f3bbab73d2 57 the configuration should be wrong.
Jerome Coutant 0:c0f3bbab73d2 58 Note: On STM32F769I-DISCOVERY, four DFSDM Channel/Filters are configured and their DMA streams are configured
Jerome Coutant 0:c0f3bbab73d2 59 in CIRCULAR mode.
Jerome Coutant 0:c0f3bbab73d2 60 + Call the function BSP_AUDIO_IN_AllocScratch(
Jerome Coutant 0:c0f3bbab73d2 61 pScratch: pointer to scratch tables
Jerome Coutant 0:c0f3bbab73d2 62 size: size of scratch buffer)
Jerome Coutant 0:c0f3bbab73d2 63 This function must be called before BSP_AUDIO_IN_RECORD() to allocate buffer scratch for each DFSDM channel
Jerome Coutant 0:c0f3bbab73d2 64 and its size.
Jerome Coutant 0:c0f3bbab73d2 65 Note: These buffers scratch are used as intermidiate buffers to collect data within final record buffer.
Jerome Coutant 0:c0f3bbab73d2 66 size is the total size of the four buffers scratch; If size is 512 then the size of each is 128.
Jerome Coutant 0:c0f3bbab73d2 67 This function must be called after BSP_AUDIO_IN_Init()
Jerome Coutant 0:c0f3bbab73d2 68 + Call the function BSP_AUDIO_IN_RECORD(
Jerome Coutant 0:c0f3bbab73d2 69 pBuf: pointer to the recorded audio data file address
Jerome Coutant 0:c0f3bbab73d2 70 Size: size of the buffer to be written in Bytes
Jerome Coutant 0:c0f3bbab73d2 71 )
Jerome Coutant 0:c0f3bbab73d2 72 to start recording from microphones.
Jerome Coutant 0:c0f3bbab73d2 73
Jerome Coutant 0:c0f3bbab73d2 74 + Call the function BSP_AUDIO_IN_Pause() to pause recording
Jerome Coutant 0:c0f3bbab73d2 75 + Call the function BSP_AUDIO_IN_Resume() to recording playing.
Jerome Coutant 0:c0f3bbab73d2 76 Note. After calling BSP_AUDIO_IN_Pause() function for pause, only BSP_AUDIO_IN_Resume() should be called
Jerome Coutant 0:c0f3bbab73d2 77 for resume (it is not allowed to call BSP_AUDIO_IN_RECORD() in this case).
Jerome Coutant 0:c0f3bbab73d2 78 + Call the function BSP_AUDIO_IN_Stop() to stop recording
Jerome Coutant 0:c0f3bbab73d2 79 + For each mode, you may need to implement the relative callback functions into your code.
Jerome Coutant 0:c0f3bbab73d2 80 The Callback functions are named BSP_AUDIO_IN_XXX_CallBack() and only their prototypes are declared in
Jerome Coutant 0:c0f3bbab73d2 81 the stm32f769i_discovery_audio.h file. (refer to the example for more details on the callbacks implementations)
Jerome Coutant 0:c0f3bbab73d2 82
Jerome Coutant 0:c0f3bbab73d2 83 Driver architecture:
Jerome Coutant 0:c0f3bbab73d2 84 --------------------
Jerome Coutant 0:c0f3bbab73d2 85 + This driver provides the High Audio Layer: consists of the function API exported in the stm32f769i_discovery_audio.h file
Jerome Coutant 0:c0f3bbab73d2 86 (BSP_AUDIO_OUT_Init(), BSP_AUDIO_OUT_Play() ...)
Jerome Coutant 0:c0f3bbab73d2 87 + This driver provide also the Media Access Layer (MAL): which consists of functions allowing to access the media containing/
Jerome Coutant 0:c0f3bbab73d2 88 providing the audio file/stream. These functions are also included as local functions into
Jerome Coutant 0:c0f3bbab73d2 89 the stm32f769i_discovery_audio.c file (DFSDMx_Init(), DFSDMx_DeInit(), SAIx_Init() and SAIx_DeInit())
Jerome Coutant 0:c0f3bbab73d2 90
Jerome Coutant 0:c0f3bbab73d2 91 Known Limitations:
Jerome Coutant 0:c0f3bbab73d2 92 ------------------
Jerome Coutant 0:c0f3bbab73d2 93 1- If the TDM Format used to play in parallel 2 audio Stream (the first Stream is configured in codec SLOT0 and second
Jerome Coutant 0:c0f3bbab73d2 94 Stream in SLOT1) the Pause/Resume, volume and mute feature will control the both streams.
Jerome Coutant 0:c0f3bbab73d2 95 2- Parsing of audio file is not implemented (in order to determine audio file properties: Mono/Stereo, Data size,
Jerome Coutant 0:c0f3bbab73d2 96 File size, Audio Frequency, Audio Data header size ...). The configuration is fixed for the given audio file.
Jerome Coutant 0:c0f3bbab73d2 97 3- Supports only Stereo audio streaming.
Jerome Coutant 0:c0f3bbab73d2 98 4- Supports only 16-bits audio data size.
