function Defaults¶
Sets the following config: MCU is master = true L/R Swap = false CSB Pin state = false Format = MSB First LJ WordLength = 24-bit
Public Attributes Documentation¶
variable mcu_is_master¶
Sets the device to slave mode if true, and master mode if false.
variable lr_swap¶
Sets whether the left/right channels are swapped or not.
variable csb_pin_state¶
Set true if tied high, and false if tied low. determines the I2C address for communicating with the device
