PDMCC26XX I2S Parameters are used when calling PDMCC26XX_I2S_open().
| PDMCC26XX_I2S_RequestMode PDMCC26XX_I2S_Params::requestMode |
Blocking or Callback mode
| uint32_t PDMCC26XX_I2S_Params::ui32requestTimeout |
Timeout for the request when in blocking mode
| PDMCC26XX_I2S_CallbackFxn PDMCC26XX_I2S_Params::callbackFxn |
Callback function pointer
| PDMCC26XX_I2S_TransferSize PDMCC26XX_I2S_Params::blockSize |
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
| void* PDMCC26XX_I2S_Params::pvContBuffer |
Pointer to consecutive buffer in memory. Driver will chunk it into the queue. Make sure to provide correct buffer size PDMCC26XX_I2S_Params.ui32conBufTotalSize
| uint32_t PDMCC26XX_I2S_Params::ui32conBufTotalSize |
Size of consecutive buffer must match total available sample size: (wanted number of blocks) * (number of samples per block) * (samplesize(in bytes)) * number of channels
| void* PDMCC26XX_I2S_Params::pvContMgtBuffer |
Pointer to consecutive buffer in memory. Driver will use this to manage buffer. Make sure to provide correct buffer size PDMCC26XX_I2S_Params.ui32conMgtBufTotalSize
| uint32_t PDMCC26XX_I2S_Params::ui32conMgtBufTotalSize |
Size of consecutive buffer must match total available sample size: (wanted number of blocks IN and OUT, it must be same number IN and OUT) * overhead size I2S_BLOCK_OVERHEAD_IN_BYTES
| PDMCC26XX_I2S_StreamNotification* PDMCC26XX_I2S_Params::currentStream |
Pointer to information about the current state of the stream
