TAS5806MD: Creating custom EQ from PPC3

Chris Bonser26

Part Number: TAS5806MD

I am trying to use a created header file from the Pure Path Studio (PPC3) and download directly to the TI5806MD amplifiers. It seems that my I2c writes are correct, and I can change things like volume control, but the EQ settings (for testing a low pass at 100hz, and a high pass at 5k) do not seem to make any impact to the audio. Not sure what I am missing.

Thanks,

Hello Chris,

Can you provide your header file. Also when generated that header file did you have the dump mode on current state after you made the EQ modifications.

Best regards,

Luis

Hello Chris,

Looking at your header file, the processing blocks aren't configured. Can you provide the PPC3 file you used to generate this dump file. All the DSP config registers are empty looking at your header file.

best regards,

Luis

Luis,

I am working with another party on this. They say that this configuration works on their test equipment. So we must be doing something wrong in extracting the header files.

Here is their PPC3 file and generated headers.
