PDMCC26XX Object.

The application must not access any member variables of this structure!

Field Documentation

§ applyCompression

bool applyCompression

Set to TRUE to apply compression. Setting it to FALSE allows user to apply own compression scheme.

§ callbackFxn

PDMCC26XX_CallbackFxn callbackFxn

Callback function pointer

§ decimationFilter

int32_t* decimationFilter

Filter that is applied if PDMCC26XX_Params::decimationFilter is set to FALSE

§ freeFxn

PDMCC26XX_FreeFxn freeFxn

Free function pointer

§ hwi

ti_sysbios_family_arm_m3_Hwi_Struct hwi

Hwi object handle

§ isOpen

bool isOpen

Has the object been opened

§ mallocFxn

PDMCC26XX_MallocFxn mallocFxn

Malloc function pointer

§ micGain

PDMCC26XX_Gain micGain

Microphone gain

§ micPowerActiveHigh

bool micPowerActiveHigh

Set to TRUE if setting the GPIO high powers the microphone

§ pcmBufferSizeInBytes

uint16_t pcmBufferSizeInBytes

Size of the pcm buffer inside the returnBuffer is equal to retBufSizeInBytes - PCM_METADATA_SIZE

§ pinHandle

PIN_Handle pinHandle

Pin driver handle

§ pinState

PIN_State pinState

Pin driver state object

§ retBufSizeInBytes

uint16_t retBufSizeInBytes

Size of returned buffers

§ startupDelayWithClockInSamples

uint32_t startupDelayWithClockInSamples

Some digital microphones have a startup delay. Set the number of samples to discard after powering the microphone starting to clock in data.

§ streamNotification

PDMCC26XX_StreamNotification* streamNotification

Stream state variable

§ streamStarted

bool streamStarted

Stream started flag

§ useDefaultFilter

bool useDefaultFilter

Set to TRUE to apply default filter. Set to FALSE to apply PDMCC26XX_Params::decimationFilter.
