Detailed Description

PDMCC26XX I2S Parameters are used when calling PDMCC26XX_I2S_open().

Field Documentation

blockCount

uint8_t blockCount

Number of PDM buffers the I2S driver can fill without the PDM driver processing them. Must be larger than 3.

blockSizeInSamples

PDMCC26XX_I2S_TransferSize blockSizeInSamples

I2S DMA transfer size in number of samples. Each sample consumes either 16 or 24 bits per channel, set by PDMCC26XX_I2S_AudioFormatConfig.memLen. Number of channels are set in PDMCC26XX_I2S_AudioPinConfig.ad0NumOfChannels and PDMCC26XX_I2S_AudioPinConfig.ad1NumOfChannels

callbackFxn

PDMCC26XX_I2S_CallbackFxn callbackFxn

Callback function pointer

currentStream

PDMCC26XX_I2S_StreamNotification* currentStream

Pointer to information about the current state of the stream

freeFxn

PDMCC26XX_I2S_FreeFxn freeFxn

Free function pointer

mallocFxn

PDMCC26XX_I2S_MallocFxn mallocFxn

Malloc function pointer

requestMode

PDMCC26XX_I2S_RequestMode requestMode

Blocking or Callback mode

requestTimeout

uint32_t requestTimeout

Timeout for the request when in blocking mode
