User NOTES
1. How To use this driver:
--------------------------
- This driver supports STM32F411xx devices on STM32F411E-Discovery Kit:
a) to play an audio file (all functions names start by BSP_AUDIO_OUT_xxx)
b) to record an audio file through MP45DT02, ST MEMS (all functions names start by AUDIO_IN_xxx)
a) PLAY A FILE:
==============
+ Call the function BSP_AUDIO_OUT_Init(
OutputDevice: physical output mode (OUTPUT_DEVICE_SPEAKER,
OUTPUT_DEVICE_HEADPHONE, OUTPUT_DEVICE_AUTO or
OUTPUT_DEVICE_BOTH)
Volume: initial volume to be set (0 is min (mute), 100 is max (100%)
AudioFreq: Audio frequency in Hz (8000, 16000, 22500, 32000 ...)
this parameter is relative to the audio file/stream type.
)
This function configures all the hardware required for the audio application (codec, I2C, I2S,
GPIOs, DMA and interrupt if needed). This function returns 0 if configuration is OK.
If the returned value is different from 0 or the function is stuck then the communication with
the codec (try to un-plug the power or reset device in this case).
- OUTPUT_DEVICE_SPEAKER: only speaker will be set as output for the audio stream.
- OUTPUT_DEVICE_HEADPHONE: only headphones will be set as output for the audio stream.
- OUTPUT_DEVICE_AUTO: Selection of output device is made through external switch (implemented
into the audio jack on the discovery board). When the Headphone is connected it is used
as output. When the headphone is disconnected from the audio jack, the output is
automatically switched to Speaker.
- OUTPUT_DEVICE_BOTH: both Speaker and Headphone are used as outputs for the audio stream
at the same time.
+ Call the function BSP_AUDIO_OUT_Play(
pBuffer: pointer to the audio data file address
Size: size of the buffer to be sent in Bytes
)
to start playing (for the first time) from the audio file/stream.
+ 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).
+ For each mode, you may need to implement the relative callback functions into your code.
The Callback functions are named BSP_AUDIO_OUT_XXXCallBack() and only their prototypes are declared in
the stm32f411e_discovery_audio.h file. (refer to the example for more details on the callbacks implementations)
+ To Stop playing, to modify the volume level, the frequency or to mute, use the functions
BSP_AUDIO_OUT_Stop(), BSP_AUDIO_OUT_SetVolume(), AUDIO_OUT_SetFrequency() BSP_AUDIO_OUT_SetOutputMode and BSP_AUDIO_OUT_SetMute().
+ The driver API and the callback functions are at the end of the stm32f411e_discovery_audio.h file.
Driver architecture:
--------------------
+ This driver provide the High Audio Layer: consists of the function API exported in the stm32f411e_discovery_audio.h file
(BSP_AUDIO_OUT_Init(), BSP_AUDIO_OUT_Play() ...)
+ This driver provide also the Media Access Layer (MAL): which consists of functions allowing to access the media containing/
providing the audio file/stream. These functions are also included as local functions into
the stm32f411e_discovery_audio.c file (I2S3_Init()...)
Known Limitations:
-------------------
1- When using the Speaker, if the audio file quality is not high enough, the speaker output
may produce high and uncomfortable noise level. To avoid this issue, to use speaker
output properly, try to increase audio file sampling rate (typically higher than 48KHz).
This operation will lead to larger file size.
2- Communication with the audio codec (through I2C) may be corrupted if it is interrupted by some
user interrupt routines (in this case, interrupts could be disabled just before the start of
communication then re-enabled when it is over). Note that this communication is only done at
the configuration phase (BSP_AUDIO_OUT_Init() or BSP_AUDIO_OUT_Stop()) and when Volume control modification is
performed (BSP_AUDIO_OUT_SetVolume() or BSP_AUDIO_OUT_SetMute()or BSP_AUDIO_OUT_SetOutputMode()).
When the audio data is played, no communication is required with the audio codec.
3- 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.
4- Supports only Stereo audio streaming. To play mono audio streams, each data should be sent twice
on the I2S or should be duplicated on the source buffer. Or convert the stream in stereo before playing.
5- Supports only 16-bits audio data size.
b) RECORD A FILE:
================
+ Call the function BSP_AUDIO_IN_Init(
AudioFreq: Audio frequency in Hz (8000, 16000, 22500, 32000 ...)
)
This function configures all the hardware required for the audio application (I2S,
GPIOs, DMA and interrupt if needed). This function returns 0 if configuration is OK.
+ Call the function BSP_AUDIO_IN_Record(
pbuf Main buffer pointer for the recorded data storing
size Current size of the recorded buffer
)
to start recording from the microphone.
+ User needs to implement user callbacks to retrieve data saved in the record buffer
(AUDIO_IN_RxHalfCpltCallback/BSP_AUDIO_IN_ReceiveComplete_CallBack)
+ Call the function AUDIO_IN_STOP() to stop recording
