| bcostm | 6:e1d9da7fe856 | 7 | * @brief This file provides the Audio driver for the STM32746G-Discovery board. |
| bcostm | 6:e1d9da7fe856 | 8 | @verbatim |
| bcostm | 6:e1d9da7fe856 | 9 | How To use this driver: |
| bcostm | 6:e1d9da7fe856 | 10 | ----------------------- |
| bcostm | 6:e1d9da7fe856 | 11 | + This driver supports STM32F7xx devices on STM32746G-Discovery (MB1191) board. |
| bcostm | 6:e1d9da7fe856 | 12 | + Call the function BSP_AUDIO_OUT_Init( |
| bcostm | 6:e1d9da7fe856 | 13 | OutputDevice: physical output mode (OUTPUT_DEVICE_SPEAKER, |
| bcostm | 6:e1d9da7fe856 | 14 | OUTPUT_DEVICE_HEADPHONE or OUTPUT_DEVICE_BOTH) |
| bcostm | 6:e1d9da7fe856 | 15 | Volume : Initial volume to be set (0 is min (mute), 100 is max (100%) |
| bcostm | 6:e1d9da7fe856 | 16 | AudioFreq : Audio frequency in Hz (8000, 16000, 22500, 32000...) |
| bcostm | 6:e1d9da7fe856 | 17 | this parameter is relative to the audio file/stream type. |
| bcostm | 6:e1d9da7fe856 | 18 | ) |
| bcostm | 6:e1d9da7fe856 | 19 | This function configures all the hardware required for the audio application (codec, I2C, SAI, |
| bcostm | 6:e1d9da7fe856 | 20 | GPIOs, DMA and interrupt if needed). This function returns AUDIO_OK if configuration is OK. |
| bcostm | 6:e1d9da7fe856 | 21 | If the returned value is different from AUDIO_OK or the function is stuck then the communication with |
| bcostm | 6:e1d9da7fe856 | 22 | the codec or the MFX has failed (try to un-plug the power or reset device in this case). |
| bcostm | 6:e1d9da7fe856 | 23 | - OUTPUT_DEVICE_SPEAKER : only speaker will be set as output for the audio stream. |
| bcostm | 6:e1d9da7fe856 | 24 | - OUTPUT_DEVICE_HEADPHONE: only headphones will be set as output for the audio stream. |
| bcostm | 6:e1d9da7fe856 | 25 | - OUTPUT_DEVICE_BOTH : both Speaker and Headphone are used as outputs for the audio stream |
| bcostm | 6:e1d9da7fe856 | 26 | at the same time. |
| bcostm | 6:e1d9da7fe856 | 27 | Note. On STM32746G-Discovery SAI_DMA is configured in CIRCULAR mode. Due to this the application |
| bcostm | 6:e1d9da7fe856 | 28 | does NOT need to call BSP_AUDIO_OUT_ChangeBuffer() to assure streaming. |
| bcostm | 6:e1d9da7fe856 | 29 | + Call the function BSP_DISCOVERY_AUDIO_OUT_Play( |
| bcostm | 6:e1d9da7fe856 | 30 | pBuffer: pointer to the audio data file address |
| bcostm | 6:e1d9da7fe856 | 31 | Size : size of the buffer to be sent in Bytes |
| bcostm | 6:e1d9da7fe856 | 32 | ) |
| bcostm | 6:e1d9da7fe856 | 33 | to start playing (for the first time) from the audio file/stream. |
| bcostm | 6:e1d9da7fe856 | 34 | + Call the function BSP_AUDIO_OUT_Pause() to pause playing |
| bcostm | 6:e1d9da7fe856 | 35 | + Call the function BSP_AUDIO_OUT_Resume() to resume playing. |
| bcostm | 6:e1d9da7fe856 | 36 | Note. After calling BSP_AUDIO_OUT_Pause() function for pause, only BSP_AUDIO_OUT_Resume() should be called |
| bcostm | 6:e1d9da7fe856 | 37 | for resume (it is not allowed to call BSP_AUDIO_OUT_Play() in this case). |
| bcostm | 6:e1d9da7fe856 | 38 | Note. This function should be called only when the audio file is played or paused (not stopped). |
| bcostm | 6:e1d9da7fe856 | 39 | + For each mode, you may need to implement the relative callback functions into your code. |
| bcostm | 6:e1d9da7fe856 | 40 | The Callback functions are named AUDIO_OUT_XXX_CallBack() and only their prototypes are declared in |
| bcostm | 6:e1d9da7fe856 | 41 | the stm32746g_discovery_audio.h file. (refer to the example for more details on the callbacks implementations) |
| bcostm | 6:e1d9da7fe856 | 42 | + To Stop playing, to modify the volume level, the frequency, the audio frame slot, |
| bcostm | 6:e1d9da7fe856 | 43 | the device output mode the mute or the stop, use the functions: BSP_AUDIO_OUT_SetVolume(), |
| bcostm | 6:e1d9da7fe856 | 44 | AUDIO_OUT_SetFrequency(), BSP_AUDIO_OUT_SetAudioFrameSlot(), BSP_AUDIO_OUT_SetOutputMode(), |
| bcostm | 6:e1d9da7fe856 | 45 | BSP_AUDIO_OUT_SetMute() and BSP_AUDIO_OUT_Stop(). |
| bcostm | 6:e1d9da7fe856 | 46 | + The driver API and the callback functions are at the end of the stm32746g_discovery_audio.h file. |
| bcostm | 6:e1d9da7fe856 | 47 | |
| bcostm | 6:e1d9da7fe856 | 48 | Driver architecture: |
| bcostm | 6:e1d9da7fe856 | 49 | -------------------- |
| bcostm | 6:e1d9da7fe856 | 50 | + This driver provides the High Audio Layer: consists of the function API exported in the stm32746g_discovery_audio.h file |
| bcostm | 6:e1d9da7fe856 | 51 | (BSP_AUDIO_OUT_Init(), BSP_AUDIO_OUT_Play() ...) |
| bcostm | 6:e1d9da7fe856 | 52 | + This driver provide also the Media Access Layer (MAL): which consists of functions allowing to access the media containing/ |
| bcostm | 6:e1d9da7fe856 | 53 | providing the audio file/stream. These functions are also included as local functions into |
| bcostm | 6:e1d9da7fe856 | 54 | the stm32746g_discovery_audio_codec.c file (SAIx_Out_Init() and SAIx_Out_DeInit(), SAIx_In_Init() and SAIx_In_DeInit()) |
| bcostm | 6:e1d9da7fe856 | 55 | |
| bcostm | 6:e1d9da7fe856 | 56 | Known Limitations: |
| bcostm | 6:e1d9da7fe856 | 57 | ------------------ |
| bcostm | 6:e1d9da7fe856 | 58 | 1- If the TDM Format used to play in parallel 2 audio Stream (the first Stream is configured in codec SLOT0 and second |
| bcostm | 6:e1d9da7fe856 | 59 | Stream in SLOT1) the Pause/Resume, volume and mute feature will control the both streams. |
| bcostm | 6:e1d9da7fe856 | 60 | 2- Parsing of audio file is not implemented (in order to determine audio file properties: Mono/Stereo, Data size, |
| bcostm | 6:e1d9da7fe856 | 61 | File size, Audio Frequency, Audio Data header size ...). The configuration is fixed for the given audio file. |
| bcostm | 6:e1d9da7fe856 | 62 | 3- Supports only Stereo audio streaming. |
| bcostm | 6:e1d9da7fe856 | 63 | 4- Supports only 16-bits audio data size. |
