    Hi ACGUY,

    Are you using the EVM board?
    I assume your system is Win-7 64 bits?
    I will try to identify the root cause of this issue as I can't reproduce it on my side. I'm using the EVM board and the control software is installed on a Win-7 64 bit system.

    ACGUY,

    I will try to replicate this issue on a similar Win-7_32 bit.
    By the way I use Win-7_64 bit with no problems, you could try to use another system like this to see of the EVM works fine.

    ACGUY,

    I have tested TLV320DAC32 EVM with an I2C master tool on a 32-bit system and it works fine too.
    Have you tried on a winXP system? Are you using the TLV320DAC32 GUI software?

    Hi Ivan,

    About device.

    I gave up on looking for solution about this issue, I using this device for engineer sample boards. Are 30-sets.
    They are all reading the status by shifting the address by 1-bit, they are no problem.


    About EVM and GUI.

    The operation is unstable. Sometimes it stops on our PCs.
    Sometimes register data is unreflect for export file.


    On this case, Is 1-bit shifted control appropriate ? Please let me know your opinion.

    Regards,
    ACGUY
