PDMCC26XX Object.
The application must not access any member variables of this structure!
| PDMCC26XX_CallbackFxn PDMCC26XX_Object::callbackFxn |
Callback function pointer
| bool PDMCC26XX_Object::useDefaultFilter |
Set to TRUE to apply default filter. Set to FALSE to apply PDMCC26XX_Params::decimationFilter.
| int32_t* PDMCC26XX_Object::decimationFilter |
Filter that is applied if PDMCC26XX_Params::decimationFilter is set to FALSE
| PDMCC26XX_Gain PDMCC26XX_Object::micGain |
Microphone gain
| 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.
| 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.
| uint16_t PDMCC26XX_Object::retBufSizeInBytes |
Size of returned buffers
| PDMCC26XX_MallocFxn PDMCC26XX_Object::mallocFxn |
Malloc function pointer
| PDMCC26XX_FreeFxn PDMCC26XX_Object::freeFxn |
Free function pointer
| PDMCC26XX_StreamNotification* PDMCC26XX_Object::streamNotification |
Stream state variable
| bool PDMCC26XX_Object::bStreamStarted |
Stream started flag
| ti_sysbios_family_arm_m3_Hwi_Struct PDMCC26XX_Object::hwi |
Hwi object handle
| Semaphore_Struct PDMCC26XX_Object::blockComplete |
Placeholder for future semaphore
| PIN_State PDMCC26XX_Object::pinState |
Pin driver state object
| PIN_Handle PDMCC26XX_Object::pinHandle |
Pin driver handle
| bool PDMCC26XX_Object::isOpen |
Has the object been opened
