The FFT can be orders of magnitude faster +* than the DFT, especially for long lengths. +* The algorithms described in this section +* operate on complex data. A separate set of functions is devoted to handling +* of real sequences. +* \par +* There are separate algorithms for handling floating-point, Q15, and Q31 data +* types. The algorithms available for each data type are described next. +* \par +* The FFT functions operate in-place. That is, the array holding the input data +* will also be used to hold the corresponding result. The input data is complex +* and contains <code>2*fftLen</code> interleaved values as shown below. +* <pre> {real[0], imag[0], real[1], imag[1],..} </pre> +* The FFT result will be contained in the same array and the frequency domain +* values will have the same interleaving. +* +* \par Floating-point +* The floating-point complex FFT uses a mixed-radix algorithm. Multiple radix-8 +* stages are performed along with a single radix-2 or radix-4 stage, as needed. +* The algorithm supports lengths of [16, 32, 64, ..., 4096] and each length uses +* a different twiddle factor table. +* \par +* The function uses the standard FFT definition and output values may grow by a +* factor of <code>fftLen</code> when computing the forward transform. The +* inverse transform includes a scale of <code>1/fftLen</code> as part of the +* calculation and this matches the textbook definition of the inverse FFT. +* \par +* Pre-initialized data structures containing twiddle factors and bit reversal +* tables are provided and defined in <code>arm_const_structs.h</code>. Include +* this header in your function and then pass one of the constant structures as +* an argument to arm_cfft_f32. For example: +* \par +* <code>arm_cfft_f32(arm_cfft_sR_f32_len64, pSrc, 1, 1)</code> +* \par +* computes a 64-point inverse complex FFT including bit reversal. +* The data structures are treated as constant data and not modified during the +* calculation. The same data structure can be reused for multiple transforms +* including mixing forward and inverse transforms. +* \par +* Earlier releases of the library provided separate radix-2 and radix-4 +* algorithms that operated on floating-point data. These functions are still +* provided but are deprecated. The older functions are slower and less general +* than the new functions. +* \par +* An example of initialization of the constants for the arm_cfft_f32 function follows: +* \code +* const static arm_cfft_instance_f32 *S; +* ... +* switch (length) { +* case 16: +* S = &arm_cfft_sR_f32_len16; +* break; +* case 32: +* S = &arm_cfft_sR_f32_len32; +* break; +* case 64: +* S = &arm_cfft_sR_f32_len64; +* break; +* case 128: +* S = &arm_cfft_sR_f32_len128; +* break; +* case 256: +* S = &arm_cfft_sR_f32_len256; +* break; +* case 512: +* S = &arm_cfft_sR_f32_len512; +* break; +* case 1024: +* S = &arm_cfft_sR_f32_len1024; +* break; +* case 2048: +* S = &arm_cfft_sR_f32_len2048; +* break; +* case 4096: +* S = &arm_cfft_sR_f32_len4096; +* break; +* } +* \endcode +* \par Q15 and Q31 +* The floating-point complex FFT uses a mixed-radix algorithm.

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 +==============================================================================*/ + +/* Includes ------------------------------------------------------------------*/ +#include "stm32l476g_discovery_audio.h" + +/** @addtogroup BSP + * @{ + */ + +/** @addtogroup STM32L476G_DISCOVERY + * @{ + */ + +/** @defgroup STM32L476G_DISCOVERY_AUDIO STM32L476G-DISCOVERY AUDIO + * @brief This file includes the low layer driver for cs43l22 Audio Codec + * available on STM32L476G-Discovery board(MB1184). + * @{ + */ + +/* Private typedef -----------------------------------------------------------*/ +/** @defgroup STM32L476G_DISCOVERY_AUDIO_Private_Types Private Types + * @{ + */ + +/* Private typedef -----------------------------------------------------------*/ + + +typedef struct +{ + + Audio_CallbackTypeDef CbError; /* pointer to the callback function invoked when ... */ + Audio_CallbackTypeDef CbHalfTransfer; /* pointer to the callback function invoked when ... */ + Audio_CallbackTypeDef CbTransferComplete; /* pointer to the callback function invoked when ... */ +} AUDIO_OUT_TypeDef; + +typedef struct +{ + DFSDM_Channel_HandleTypeDef hDfsdmLeftChannel; /* DFSDM channel handle used for left channel */ + DMA_HandleTypeDef hDmaDfsdmLeft; /* DMA handle used for DFSDM regular conversions on left channel */ + int32_t * LeftRecBuff; /* Buffers for left samples */ + uint32_t Frequency; /* Record Frequency */ + uint32_t BitResolution; /* Record bit resolution */ + uint32_t ChannelNbr; /* Record Channel Number */ + uint16_t * pRecBuf; /* Pointer to record user buffer */ + uint32_t RecSize; /* Size to record in mono, double size to record in stereo */ + Audio_CallbackTypeDef CbError; /* pointer to the callback function invoked when a DMA transfer fails */ + Audio_CallbackTypeDef CbHalfTransfer; /* pointer to the callback function invoked when half of the DMA transfer is completed */ + Audio_CallbackTypeDef CbTransferComplete; /* pointer to the callback function invoked when the DMA transfer is completed */ +} AUDIO_IN_TypeDef; + +/** + * @} + */ + +/* Private defines ------------------------------------------------------------*/ +/** @defgroup STM32L476G_DISCOVERY_AUDIO_Private_Constants Private Constants + * @{ + */ +/** + * @} + */ + +/* Private macros ------------------------------------------------------------*/ +/** @defgroup STM32L476G_DISCOVERY_AUDIO_Private_Macros Private Macros + * @{ + */ +/*### PLAY ###*/ +/* SCK(kHz) = SAI_CK_x/(SAIClockDivider*2*256) */ +#define SAIClockDivider(__FREQUENCY__) \ + (__FREQUENCY__ == AUDIO_FREQUENCY_8K) ? 12 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_11K) ? 2 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_16K) ? 6 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_22K) ? 1 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_32K) ? 3 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_44K) ? 0 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_48K) ? 2 : 1 \ + +/*### RECORD ###*/ +#define DFSDMOverSampling(__FREQUENCY__) \ + (__FREQUENCY__ == AUDIO_FREQUENCY_8K) ? 256 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_11K) ? 256 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_16K) ? 128 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_22K) ? 128 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_32K) ? 64 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_44K) ? 64 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_48K) ? 32 : 16 \ + +#define DFSDMClockDivider(__FREQUENCY__) \ + (__FREQUENCY__ == AUDIO_FREQUENCY_8K) ? 24 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_11K) ? 4 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_16K) ? 24 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_22K) ? 4 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_32K) ? 24 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_44K) ? 4 \ + : (__FREQUENCY__ == AUDIO_FREQUENCY_48K) ? 32 : 32 \ + +#define DFSDMFilterOrder(__FREQUENCY__) \ + (__FREQUENCY__ == AUDIO_FREQUENCY_8K) ?
