TAS2505: The equipment dosen't work after I configute I2C according to the 4.0.11 Example from TAS2505 Application Reference Guide

Part Number: TAS2505

dear FAE,

I  configute I2C according to  the 4.0.11 Example  from TAS2505 Application Reference Guide in order to check whether the TAS2505 work or not. My configuration is as follow:

I2C address is 0x30 , MCLK is 11.2896MHz and the Fs is 44.1KHz. And the I2C configuration is totally the same with the example.

However , there is no response from the device. Hope receive the response soon!

  • Hi, welcome to e2e,

    Are you using the EVM board? Also are you using the device GUI? In case you're not using the EVM board, could you please share your schematic?
    Could you read back the device registers so we can make sure that they're properly setup and I2C communication is working fine?

    Best regards,

  • The I2C which I received is a little bit different from what I write to the I2C, according to the Application Reference Guide, 

    30 00 00

    30 04 00

    30 0B 81

    30 0C 82

    30 0D 00

    30 0E 80

    However, what I read from I2C is 

    0B 81

    0C 7E

    0D 03

    0E 7B

    And I have affirmed that the SDA and SCL have been received by the device correctly.

    My device schematic is in the attach.

    Hope receive the reply soon!
