* @brief This file provides the Audio driver for the STM32H7S78_DK
* discovery board.
@verbatim
How To use this driver:
-----------------------
+ This driver supports STM32H7RSxx devices on STM32H7S78_DK (MB1736) board.
+ Call the function BSP_AUDIO_OUT_Init() for AUDIO OUT initialization:
Instance : Select the output instance. Can only be 0 (I2S).
AudioInit: Audio Out structure to select the following parameters.
- Device: Select the output device (headphone, speaker, ..).
- SampleRate: Select the output sample rate (8Khz .. 96Khz).
- BitsPerSample: Select the output resolution (16 or 32bits per sample).
- ChannelsNbr: Select the output channels number(1 for mono, 2 for stereo).
- Volume: Select the output volume(0% .. 100%).
This function configures all the hardware required for the audio application (codec, I2C, I2S,
GPIOs, DMA and interrupt if needed). This function returns BSP_ERROR_NONE if configuration is OK.
If the returned value is different from BSP_ERROR_NONE or the function is stuck then the communication with
the codec has failed (try to un-plug the power or reset device in this case).
User can update the I2S or the clock configurations by overriding the weak MX functions MX_I2S6_Init()
and MX_I2S6_ClockConfig().
User can override the default MSP configuration and register his own MSP callbacks (defined at application level)
by calling BSP_AUDIO_OUT_RegisterMspCallbacks() function.
User can restore the default MSP configuration by calling BSP_AUDIO_OUT_RegisterDefaultMspCallbacks().
To use these two functions, user has to enable USE_HAL_I2S_REGISTER_CALLBACKS within stm32h7rsxx_hal_conf.h file.
+ Call the function BSP_AUDIO_OUT_Play() to play audio stream:
Instance : Select the output instance. Can only be 0 (I2S).
pBuf: pointer to the audio data file address.
NbrOfBytes: Total size of the buffer to be sent in Bytes.
+ Call the function BSP_AUDIO_OUT_Pause() to pause playing.
+ Call the function BSP_AUDIO_OUT_Resume() to resume playing.
Note. After calling BSP_AUDIO_OUT_Pause() function for pause, only BSP_AUDIO_OUT_Resume() should be called
for resume (it is not allowed to call BSP_AUDIO_OUT_Play() in this case).
Note. This function should be called only when the audio file is played or paused (not stopped).
+ Call the function BSP_AUDIO_OUT_Stop() to stop playing.
+ Call the function BSP_AUDIO_OUT_Mute() to mute the player.
+ Call the function BSP_AUDIO_OUT_UnMute() to unmute the player.
+ Call the function BSP_AUDIO_OUT_IsMute() to get the mute state(BSP_AUDIO_MUTE_ENABLED or BSP_AUDIO_MUTE_DISABLED).
+ Call the function BSP_AUDIO_OUT_SetDevice() to update the AUDIO OUT device.
+ Call the function BSP_AUDIO_OUT_GetDevice() to get the AUDIO OUT device.
+ Call the function BSP_AUDIO_OUT_SetSampleRate() to update the AUDIO OUT sample rate.
+ Call the function BSP_AUDIO_OUT_GetSampleRate() to get the AUDIO OUT sample rate.
+ Call the function BSP_AUDIO_OUT_SetBitsPerSample() to update the AUDIO OUT resolution.
+ Call the function BSP_AUDIO_OUT_GetBitPerSample() to get the AUDIO OUT resolution.
+ Call the function BSP_AUDIO_OUT_SetChannelsNbr() to update the AUDIO OUT number of channels.
+ Call the function BSP_AUDIO_OUT_GetChannelsNbr() to get the AUDIO OUT number of channels.
+ Call the function BSP_AUDIO_OUT_SetVolume() to update the AUDIO OUT volume.
+ Call the function BSP_AUDIO_OUT_GetVolume() to get the AUDIO OUT volume.
+ Call the function BSP_AUDIO_OUT_GetState() to get the AUDIO OUT state.
+ BSP_AUDIO_OUT_SetDevice(), BSP_AUDIO_OUT_SetSampleRate(), BSP_AUDIO_OUT_SetBitsPerSample() and
BSP_AUDIO_OUT_SetChannelsNbr() cannot be called while the state is AUDIO_OUT_STATE_PLAYING.
+ For each mode, you may need to implement the relative callback functions into your code.
The Callback functions are named AUDIO_OUT_XXX_CallBack() and only their prototypes are declared in
the stm32h7s78_discovery_audio.h file. (refer to the example for more details on the callbacks implementations).
+ Call the function BSP_AUDIO_IN_Init() for AUDIO IN initialization:
Instance : Select the input instance. Can be 0 (I2S) or 1 (MDF).
AudioInit: Audio In structure to select the following parameters.
- Device: Select the input device (analog, digital mic1, mic2, mic1 & mic2).
- SampleRate: Select the input sample rate (8Khz .. 96Khz).
- BitsPerSample: Select the input resolution (16 or 32bits per sample).
- ChannelsNbr: Select the input channels number(1 for mono, 2 for stereo).
- Volume: Select the input volume(0% .. 100%).
This function configures all the hardware required for the audio application (codec, I2C, I2S, MDF
GPIOs, DMA and interrupt if needed). This function returns BSP_ERROR_NONE if configuration is OK.
If the returned value is different from BSP_ERROR_NONE or the function is stuck then the communication with
the codec has failed (try to un-plug the power or reset device in this case).
User can update the MDF/I2S or the clock configurations by overriding the weak MX functions MX_I2S6_Init(),
MX_I2S6_ClockConfig(), MX_ADF1_Init() and MX_ADF1_ClockConfig()
User can override the default MSP configuration and register his own MSP callbacks (defined at application level)
by calling BSP_AUDIO_IN_RegisterMspCallbacks() function.
User can restore the default MSP configuration by calling BSP_AUDIO_IN_RegisterDefaultMspCallbacks().
To use these two functions, user have to enable USE_HAL_I2S_REGISTER_CALLBACKS and/or USE_HAL_MDF_REGISTER_CALLBACKS
within stm32h7rsxx_hal_conf.h file.
+ Call the function BSP_AUDIO_IN_Record() to record audio stream. The recorded data are stored to user buffer in raw
(L, R, L, R ...).
Instance : Select the input instance. Can be 0 (I2S) or 1 (MDF).
pBuf: pointer to user buffer.
NbrOfBytes: Total size of the buffer to be sent in Bytes.
+ Call the function BSP_AUDIO_IN_Pause() to pause recording.
+ Call the function BSP_AUDIO_IN_Resume() to resume recording.
+ Call the function BSP_AUDIO_IN_Stop() to stop recording.
+ Call the function BSP_AUDIO_IN_SetDevice() to update the AUDIO IN device.
+ Call the function BSP_AUDIO_IN_GetDevice() to get the AUDIO IN device.
+ Call the function BSP_AUDIO_IN_SetSampleRate() to update the AUDIO IN sample rate.
+ Call the function BSP_AUDIO_IN_GetSampleRate() to get the AUDIO IN sample rate.
+ Call the function BSP_AUDIO_IN_SetBitPerSample() to update the AUDIO IN resolution.
+ Call the function BSP_AUDIO_IN_GetBitPerSample() to get the AUDIO IN resolution.
+ Call the function BSP_AUDIO_IN_SetChannelsNbr() to update the AUDIO IN number of channels.
+ Call the function BSP_AUDIO_IN_GetChannelsNbr() to get the AUDIO IN number of channels.
+ Call the function BSP_AUDIO_IN_SetVolume() to update the AUDIO IN volume.
+ Call the function BSP_AUDIO_IN_GetVolume() to get the AUDIO IN volume.
+ Call the function BSP_AUDIO_IN_GetState() to get the AUDIO IN state.
+ For each mode, you may need to implement the relative callback functions into your code.
The Callback functions are named AUDIO_IN_XXX_CallBack() and only their prototypes are declared in
the stm32h7s78_discovery_audio.h file (refer to the example for more details on the callbacks implementations).
+ The driver API and the callback functions are at the end of the stm32h7s78_discovery_audio.h file.
Known Limitations:
------------------
1- If the TDM Format used to play in parallel 2 audio Stream (the first Stream is configured in codec SLOT0 and second
Stream in SLOT1) the Pause/Resume, volume and mute feature will control the both streams.
2- Parsing of audio file is not implemented (in order to determine audio file properties: Mono/Stereo, Data size,
File size, Audio Frequency, Audio Data header size ...). The configuration is fixed for the given audio file.
