Member Enumeration Documentation

◆ Format

enum class daisy::Wm8731::Config::Format

strong

Sets the communication format used

Enumerator
MSB_FIRST_RJ
MSB_FIRST_LJ
I2S
DSP

◆ WordLength

enum class daisy::Wm8731::Config::WordLength

strong

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.

◆ Defaults()

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

inline

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

◆ 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

◆ fmt

◆ lr_swap

bool daisy::Wm8731::Config::lr_swap

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

◆ mcu_is_master

bool daisy::Wm8731::Config::mcu_is_master

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

◆ wl
