TAS2557: Configuring with Binary Dump in Tuning Mode

Gui Borba
Prodigy 180 points
Part Number: TAS2557


Hello,

I am using the TAS2557 device in my system without the ROM mode. To configure it so far, I snooped the I2C bus to get all register writes that PPC performed to configure the device, and this appears to work. However, when I perform a binary dump in the "End System Integration" part of PPC3, I get a "combined_configuration" file with  > 10,000 register writes, which appears to be a lot more than what PPC3 is doing.

I am trying to understand why this dump is so large, and if there are any differences between it and what PPC does during live tuning of the device. Can you elaborate? How can I minimize this configuration?

Regards,

Gui

    Hi Gui,

    I am going to research the difference between the two process. I will be responding with further information the next week.

    Hi Gui,

    I have researched this.
    The writing registers should be similar between the binary files and PPC3. Any subsequent changes in the Audio Processing will write minimal changes in the files. Perhaps, you didn't get all the files in Audio Processing, so you can get full writing registers in Audio Processing with the following steps:
    1. Open the App Center, go to the TAS2557 homepage.
    2. Open I2C Monitor and start recording option.
    3. Click on Audio Processing option. Let the page load completely or try "Reload Tuning" from the setting wheel in Audio Processing.
