class ATOMEchoBase

Constructors

class ATOMEchoBase(i2c, address: int = 0x18, i2s_port: int = 1, sample_rate: int = 44100, i2s_sck: int = -1, i2s_ws: int = -1, i2s_di: int = -1, i2s_do: int = -1)

Create an ATOMEchoBase object.

参数:

• i2c (I2C) – I2C object

• address (int) – The I2C address of the ES8311. Default is 0x18.

• i2s_port (int) – The I2S port number. Default is 1.

• sample_rate (int) – The sample rate of the audio. Default is 44100.

• i2s_sck (int) – The I2S SCK pin. Default is -1.

• i2s_ws (int) – The I2S WS pin. Default is -1.

• i2s_di (int) – The I2S DI pin. Default is -1.

• i2s_do (int) – The I2S DO pin. Default is -1.
