-/*==============================================================================
- User NOTES
-
-1. How To use this driver:
---------------------------
- + This driver supports STM32L4xx devices on STM32L476G-Discovery (MB1184) Discovery boards.
- a) to play an audio file (all functions names start by BSP_AUDIO_OUT_xxx)
- b) to record an audio file through MP34DT01TR, ST MEMS (all functions names start by BSP_AUDIO_IN_xxx)
-
-a) PLAY A FILE:
-==============
- + Call the function BSP_AUDIO_OUT_Init(
- OutputDevice: physical output mode (OUTPUT_DEVICE_SPEAKER,
- OUTPUT_DEVICE_HEADPHONE 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, SAI,
- GPIOs, DMA and interrupt if needed). This function returns AUDIO_OK if configuration is OK.
- If the returned value is different from AUDIO_OK or the function is stuck then the communication with
- the audio codec has failed.
- - 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_BOTH : both Speaker and Headphone are used as outputs for the audio stream
- at the same time.
-
- + Call the function BSP_AUDIO_OUT_RegisterCallbacks to register user callbacks
- required to manage audio data streaming towards the audio codec (ErrorCallback(),
- HalfTransfer_CallBack() and TransferComplete_CallBack()).
-
- + Call the function BSP_AUDIO_OUT_Play() to start audio playback (for the first time).
- + Call the function BSP_AUDIO_OUT_Pause() to pause audio playabck
- + Call the function BSP_AUDIO_OUT_Resume() to resume audio playback.
- 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 audio playback.
- + To modify the volume level, the sampling frequency, the device output mode,
- the mute status or the audio configuration or the stop, use the functions: BSP_AUDIO_OUT_SetVolume(),
- AUDIO_OUT_SetFrequency(), BSP_AUDIO_OUT_SetOutputMode(), BSP_AUDIO_OUT_SetMute()and
- BSP_AUDIO_OUT_ChangeAudioConfig().
-
-Driver architecture:
---------------------
- + This driver provides the audio layer high level API: it consists in functions
- exported in the stm32l476g_discovery_audio.h file (e.g. BSP_AUDIO_OUT_Init(),
- BSP_AUDIO_OUT_Play(), ...).
- + This driver also includes the Media Access Layer (MAL): it consists in
- functions allowing to access setup the audio devices. These functions
- are included as local functions into the stm32l476g_discovery_audio.c file
- (e.g. AUDIO_SAIx_Init()).
-
-Known Limitations:
-------------------
- 1- 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.
- 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.
- 3- 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 (DFSDM,
- GPIOs, DMA and interrupt if needed). This function returns AUDIO_OK if the
- configuration completes successfully.
-
- + Call the function BSP_AUDIO_IN_RegisterCallbacks to register user callbacks
- used to stream audio data toward the record buffer (ErrorCallback(),
- HalfTransfer_CallBack() and TransferComplete_CallBack()).
-
- + 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.
-
- + Call the function AUDIO_IN_STOP() to stop recording

- GLASS LCD MAPPING
-================================================================================
-LCD allows to display informations on six 14-segment digits and 4 bars:
-
- 1 2 3 4 5 6
------ ----- ----- ----- ----- -----
-|\|/| o |\|/| o |\|/| o |\|/| o |\|/| |\|/| BAR3
--- -- -- -- -- -- -- -- -- -- -- -- BAR2
-|/|\| o |/|\| o |/|\| o |/|\| o |/|\| |/|\| BAR1
------ * ----- * ----- * ----- * ----- ----- BAR0
-
-LCD segment mapping:
---------------------
- -----A----- _
- |\ | /| COL |_|
- F H J K B
- | \ | / | _
- --G-- --M-- COL |_|
- | / | \ |
- E Q P N C
- |/ | \| _
- -----D----- DP |_|
-
- An LCD character coding is based on the following matrix:
-COM 0 1 2 3
-SEG(n) { E , D , P , N }
-SEG(n+1) { M , C , COL , DP }
-SEG(23-n-1) { B , A , K , J }
-SEG(23-n) { G , F , Q , H }
-with n positive odd number.
-
- The character 'A' for example is:
- -------------------------------
-LSB { 1 , 0 , 0 , 0 }
- { 1 , 1 , 0 , 0 }
- { 1 , 1 , 0 , 0 }
-MSB { 1 , 1 , 0 , 0 }
- -------------------
- 'A' = F E 0 0 hexa

+ User NOTES
+
+1. How To use this driver:
+--------------------------
+ + This driver supports STM32L4xx devices on STM32L476G-Nucleo (MB1184) Nucleo boards.
+ a) to play an audio file (all functions names start by BSP_AUDIO_OUT_xxx)
+ b) to record an audio file through MP34DT01TR, ST MEMS (all functions names start by BSP_AUDIO_IN_xxx)
+
+a) PLAY A FILE:
+==============
+ + Call the function BSP_AUDIO_OUT_Init(
+ OutputDevice: physical output mode (OUTPUT_DEVICE_SPEAKER,
+ OUTPUT_DEVICE_HEADPHONE 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, SAI,
+ GPIOs, DMA and interrupt if needed). This function returns AUDIO_OK if configuration is OK.
+ If the returned value is different from AUDIO_OK or the function is stuck then the communication with
+ the audio codec has failed.
+ - 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_BOTH : both Speaker and Headphone are used as outputs for the audio stream
+ at the same time.
+
+ + Call the function BSP_AUDIO_OUT_RegisterCallbacks to register user callbacks
+ required to manage audio data streaming towards the audio codec (ErrorCallback(),
+ HalfTransfer_CallBack() and TransferComplete_CallBack()).
+
+ + Call the function BSP_AUDIO_OUT_Play() to start audio playback (for the first time).
+ + Call the function BSP_AUDIO_OUT_Pause() to pause audio playabck
+ + Call the function BSP_AUDIO_OUT_Resume() to resume audio playback.
+ 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 audio playback.
+ + To modify the volume level, the sampling frequency, the device output mode,
+ the mute status or the audio configuration or the stop, use the functions: BSP_AUDIO_OUT_SetVolume(),
+ AUDIO_OUT_SetFrequency(), BSP_AUDIO_OUT_SetOutputMode(), BSP_AUDIO_OUT_SetMute()and
+ BSP_AUDIO_OUT_ChangeAudioConfig().
+
+Driver architecture:
+--------------------
+ + This driver provides the audio layer high level API: it consists in functions
+ exported in the stm32l4xx_nucleo_audio.h file (e.g. BSP_AUDIO_OUT_Init(),
+ BSP_AUDIO_OUT_Play(), ...).
+ + This driver also includes the Media Access Layer (MAL): it consists in
+ functions allowing to access setup the audio devices. These functions
+ are included as local functions into the stm32l4xx_nucleo_audio.c file
+ (e.g. AUDIO_SAIx_Init()).
+
+Known Limitations:
+------------------
+ 1- 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.
+ 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.
+ 3- 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 (DFSDM,
+ GPIOs, DMA and interrupt if needed). This function returns AUDIO_OK if the
+ configuration completes successfully.
+
+ + Call the function BSP_AUDIO_IN_RegisterCallbacks to register user callbacks
+ used to stream audio data toward the record buffer (ErrorCallback(),
+ HalfTransfer_CallBack() and TransferComplete_CallBack()).
+
+ + 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.
+
+ + Call the function AUDIO_IN_STOP() to stop recording
