Detailed Description

PDMCC26XX Object.

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

Field Documentation

bool PDMCC26XX_Object::useDefaultFilter

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

bool PDMCC26XX_Object::streamStarted

Stream started flag

bool PDMCC26XX_Object::micPowerActiveHigh

Set to TRUE if setting the GPIO high powers the microphone

bool PDMCC26XX_Object::applyCompression

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

bool PDMCC26XX_Object::isOpen

Has the object been opened

uint16_t PDMCC26XX_Object::retBufSizeInBytes

Size of returned buffers

uint16_t PDMCC26XX_Object::pcmBufferSizeInBytes

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

uint32_t PDMCC26XX_Object::startupDelayWithClockInSamples

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

int32_t* PDMCC26XX_Object::decimationFilter

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

PDMCC26XX_StreamNotification* PDMCC26XX_Object::streamNotification

Stream state variable

PDMCC26XX_Gain PDMCC26XX_Object::micGain

Microphone gain

PDMCC26XX_CallbackFxn PDMCC26XX_Object::callbackFxn

Callback function pointer

PDMCC26XX_MallocFxn PDMCC26XX_Object::mallocFxn

Malloc function pointer

PDMCC26XX_FreeFxn PDMCC26XX_Object::freeFxn

Free function pointer

PIN_State PDMCC26XX_Object::pinState

Pin driver state object

PIN_Handle PDMCC26XX_Object::pinHandle

Pin driver handle

ti_sysbios_family_arm_m3_Hwi_Struct PDMCC26XX_Object::hwi

Hwi object handle
