Field Documentation

uint8_t PDMCC26XX_I2S_Params::blockCount

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

uint32_t PDMCC26XX_I2S_Params::requestTimeout

Timeout for the request when in blocking mode

PDMCC26XX_I2S_RequestMode PDMCC26XX_I2S_Params::requestMode

Blocking or Callback mode

PDMCC26XX_I2S_TransferSize PDMCC26XX_I2S_Params::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

PDMCC26XX_I2S_CallbackFxn PDMCC26XX_I2S_Params::callbackFxn

Callback function pointer

PDMCC26XX_I2S_MallocFxn PDMCC26XX_I2S_Params::mallocFxn

Malloc function pointer

PDMCC26XX_I2S_FreeFxn PDMCC26XX_I2S_Params::freeFxn

Free function pointer

PDMCC26XX_I2S_StreamNotification* PDMCC26XX_I2S_Params::currentStream

Pointer to information about the current state of the stream
