TLV320AIC3100: default settings / startup

Part Number: TLV320AIC3100

Hi Champs,

Customer is asking if we could provide or point to a description/guide for a quickstart of this device. Are there default settings needed to know to have it working?

Can we activate a sound from the beep generator as a first test?

    hello Simon,

    The EVM GUI provides an example setup, but it is specific to the default clock setup for the EVM.

    see below setup for audio playback,  I believe this script assumes an MCLK of 12.288MHz, and the data format is I2S, 16bit and the device is in slave mode.

    # --------------------------------------------------------------- page 0 is selected

    # PLL_clkin = MCLK,codec_clkin = PLL_CLK
    w 30 04 03
    # PLL Power up, P = 1, R = 1

    # J = 8

    # D = 0000, D(13:8) = 0

    # mode is i2s,wordlength is 16

    # POWERUP DAC left and right channels (soft step disable)
    w 30 3f d6
    # UNMUTE DAC left and right channels
    > 00

    There is also a beep generator application note that has an example script.

    Best regards,
