Field Documentation

§ audioClkCfg

PDMCC26XX_I2S_AudioClockConfig audioClkCfg

I2S clock division override and clock config

§ audioFmtCfg

PDMCC26XX_I2S_AudioFormatConfig audioFmtCfg

I2S audio format configuration

§ audioPinCfg

PDMCC26XX_I2S_AudioPinConfig audioPinCfg

I2S pin configuration

§ blockComplete

Semaphore_Struct blockComplete

Notify complete PDMCC26XX_I2S block transfer

§ blockCount

uint8_t blockCount

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

§ blockSizeInBytes

uint16_t blockSizeInBytes

Size of an individual PDM block buffer in bytes

§ blockSizeInSamples

PDMCC26XX_I2S_TransferSize blockSizeInSamples

I2S DMA transfer size, determines the block size in number of samples. Each sample consumes either 16 or 24 bits, set by PDMCC26XX_I2S_AudioFormatConfig.memLen

§ requestMode

PDMCC26XX_I2S_RequestMode requestMode

Blocking or return mode

§ requestTimeout

uint32_t requestTimeout

Timeout for the request when in blocking mode

§ sampleRate

int32_t sampleRate

I2S bit clock frequency in Hz. If negative, or not one of I2S_SAMPLE_RATE_16K/_24K/_32K/_48K then use user configured clock division.

§ semStopping

Semaphore_Struct semStopping

PDMCC26XX_I2S stopping sequence semaphore
