TAS6584-Q1: Gain Compensation Biquad Coefficient Writing

Good Morning!

I am looking for a register map or the gain compensation biquads. I cannot seem to find it anywhere, is it possible to obtain that information so I can change these filter values manually? Thank you very much, I would ideally be able to use a custom I2C interface to initialize these on startup.

Best Regards,

Levi,

It is best to use the PPC3 GUI to adjust the biquad as needed. The changed values are found by monitoring the I2C code with the built-in logger. There are 24 built-in functions for the biquad. Or you can create your own with the GUI. This is much easier than calculating the values,

I've downloaded PPC3, but it is my understanding I must request access to the EVM. I have done so and am waiting to hear back! Thank you again! I am hoping they approve my access soon, and i can check the I2C codes like you're saying.

Levi,

You can run the PPC3 without an EVM to see what I2c registers it will send out.
