Public Types Documentation¶

enum BitDepth¶

enum daisy::SaiHandle::Config::BitDepth {
    SAI_16BIT,
    SAI_24BIT,
    SAI_32BIT
};

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

enum Direction¶

enum daisy::SaiHandle::Config::Direction {
    TRANSMIT,
    RECEIVE
};

Specifies the direction for each peripheral block.

enum Peripheral¶

enum daisy::SaiHandle::Config::Peripheral {
    SAI_1,
    SAI_2
};

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

enum SampleRate¶

enum daisy::SaiHandle::Config::SampleRate {
    SAI_8KHZ,
    SAI_16KHZ,
    SAI_32KHZ,
    SAI_48KHZ,
    SAI_96KHZ
};

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

enum Sync¶

enum daisy::SaiHandle::Config::Sync {
    MASTER,
    SLAVE
};

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.
