TAS5756 programming for software engineer

Other Parts Discussed in Thread: TAS5756M

Hello

Would you please let me know the way to have .cfg file which includes  EQ-curves designed by customer in PPC2?

The Software engineer in my customer want to know the way Now.

 

I had read TAS5756 data sheet page 65, and I understood the way about Register Dump to cfg file by PPC2.

However, as data sheet says " baseline " as below , the file which I had Dumped seems always same

even though  I had changed the Biquad.

I want to know the way to have cfg files including EQ-curves which is designed by PPC2 by customer.

I need to have anything using " Save setting " file? 

--- data sheet p 65 ---

 

http://www.ti.com/lit/ds/symlink/tas5756m.pdf

. Use the Register Dump feature of the PPC software to generate a baseline configuration file.                                                                  

                                                                                                            ````````````````````````````

. Generate additional configuration files based upon operating modes of the end-equipment and integrate static  configuration information into initialization files.

 

. Integrate dynamic controls (such as volume controls, mute commands, and mode-based EQ curves  into the main system program.

 

I need your answer within 2days

    Hi, Shibatani-san,

    The Register Dump and System Build Features of the TAS5756M GUI are used to export all the register settings of the amplifier. As these features make a read of the registers of the amplifier, you need to load the desired Hybrid Flow to the amplifier before exporting. You need to follow the next sequence to export a configuration file with the configurations made in the EQ and other processing of the amplifier: 

    1. Run HybridFlow
    2. Tune Audio Processing
    3. Stop HybridFlow
    4. Export

    It is recommended to export the settings only when the HybridFlow is stopped.

    So, if different EQ curves are required, you might need to repeat these steps for each different curve. Another solution to accomplish this would be to monitor the changes made to the BQ coefficients while running the HybridFlow by using the I²C logging tool. By doing this, you would be able to check the registers that are changed to implement the filter change. Then, you can just write these coefficients after running the initial configuration to get a different EQ curve. 

    Save settings tool is used to save the settings configured in the GUI (i.e. type of HybridFlow, DAP settings, input configuration, etc...).
