Public Types Documentation¶

enum Format¶

enum daisy::Wm8731::Config::Format {
    MSB_FIRST_RJ = 0x00,
    MSB_FIRST_LJ = 0x01,
    I2S = 0x02,
    DSP = 0x03
};

Sets the communication format used

enum WordLength¶

enum daisy::Wm8731::Config::WordLength {
    BITS_16 = (0x00 << 2),
    BITS_20 = (0x01 << 2),
    BITS_24 = (0x02 << 2),
    BITS_32 = (0x03 << 2)
};

Defines the size of a sample in bits This is for communication only, the device processes audio at 24-bits, and the strips/pads bits to send to the processor.

Public Attributes Documentation¶

variable csb_pin_state¶

bool daisy::Wm8731::Config::csb_pin_state;

Set true if tied high, and false if tied low. determines the I2C address for communicating with the device

variable fmt¶

Format daisy::Wm8731::Config::fmt;

variable lr_swap¶

bool daisy::Wm8731::Config::lr_swap;

Sets whether the left/right channels are swapped or not.

variable mcu_is_master¶

bool daisy::Wm8731::Config::mcu_is_master;

Sets the device to slave mode if true, and master mode if false.

variable wl¶

WordLength daisy::Wm8731::Config::wl;

Public Functions Documentation¶

function Defaults¶

inline void daisy::Wm8731::Config::Defaults ()

Sets the following config: MCU is master = true L/R Swap = false CSB Pin state = false Format = MSB First LJ WordLength = 24-bit
