PDMCC26XX_I2S Object.
The application must not access any member variables of this structure!
| PDMCC26XX_I2S_RequestMode PDMCC26XX_I2S_Object::requestMode |
Blocking or return mode
| uint32_t PDMCC26XX_I2S_Object::ui32requestTimeout |
Timeout for the request when in blocking mode
| PDMCC26XX_I2S_CallbackFxn PDMCC26XX_I2S_Object::callbackFxn |
Callback function pointer
| int32_t PDMCC26XX_I2S_Object::i32SampleRate |
I2S bit clock frequency in Hz. If negative, or not one of I2S_SAMPLE_RATE_16K/_24K/_32K/_48K then use user configured clock division.
| PDMCC26XX_I2S_AudioClockConfig PDMCC26XX_I2S_Object::audioClkCfg |
I2S clock division override and clock config
| PDMCC26XX_I2S_AudioPinConfig PDMCC26XX_I2S_Object::audioPinCfg |
I2S pin configuration
| PDMCC26XX_I2S_AudioFormatConfig PDMCC26XX_I2S_Object::audioFmtCfg |
I2S audio format configuration
| PDMCC26XX_I2S_TransferSize PDMCC26XX_I2S_Object::blockSize |
I2S DMA transfer size, determines the block size in number of samples. Each sample consumes either 16 or 24 bits, set by PDMCC26XX_I2S_AudioFormatConfig.memLen
| void* PDMCC26XX_I2S_Object::pvContBuffer |
Pointer to consecutive buffer in memory. Driver will chunk it into the queue
| uint32_t PDMCC26XX_I2S_Object::ui32conBufTotalSize |
Size of consecutive buffer must match total available sample size: block * number of samples * samplesize(in bytes) * number of channels
| void* PDMCC26XX_I2S_Object::pvContMgtBuffer |
Pointer to consecutive buffer in memory. Driver will use this to manage buffer
| uint32_t PDMCC26XX_I2S_Object::ui32conMgtBufTotalSize |
Size of consecutive buffer must match total available sample size: wanted number of blocks in and out (must be same number in and out) * overhead size ()
| PDMCC26XX_I2S_StreamNotification* PDMCC26XX_I2S_Object::currentStream |
Ptr to information about the current transaction
| ti_sysbios_family_arm_m3_Hwi_Struct PDMCC26XX_I2S_Object::hwi |
Hwi object handle
| Semaphore_Struct PDMCC26XX_I2S_Object::blockComplete |
Notify complete PDMCC26XX_I2S block transfer
| Semaphore_Struct PDMCC26XX_I2S_Object::semStopping |
PDMCC26XX_I2S stopping sequence semaphore
| PIN_State PDMCC26XX_I2S_Object::pinState |
PIN driver state object
| PIN_Handle PDMCC26XX_I2S_Object::pinHandle |
PIN driver handle
| bool PDMCC26XX_I2S_Object::isOpen |
Has the object been opened
