Member Enumeration Documentation

BitDepth

enum class daisy::SaiHandle::Config::BitDepth

strong

Bit Depth that the hardware expects to be transferred to/from the device.

Enumerator
SAI_16BIT
SAI_24BIT
SAI_32BIT

Direction

enum class daisy::SaiHandle::Config::Direction

strong

Specifies the direction for each peripheral block.

Enumerator
TRANSMIT
RECEIVE

Peripheral

enum class daisy::SaiHandle::Config::Peripheral

strong

Specifies the internal peripheral to use (mapped to different hardware pins)

Enumerator
SAI_1
SAI_2

SampleRate

enum class daisy::SaiHandle::Config::SampleRate

strong

Rate at which samples will be streaming to/from the device.

Enumerator
SAI_8KHZ
SAI_16KHZ
SAI_32KHZ
SAI_48KHZ
SAI_96KHZ

Sync

enum class daisy::SaiHandle::Config::Sync

strong

Specifies whether a particular block is the master or the slave If both are set to slave, no MCLK signal will be used, and it is expected that the codec will have its own xtal.

Enumerator
MASTER
SLAVE
