Changing DSP mux select at runtime

Susan Williams

I have a question about using PurePath Studio. I created a project that contains a mux. I generate the code for it, and in my product I'm going to load that code on the codec but I want to be able to go in and toggle the mux select. How do I know what register that is in? It must be one of the coefficients, but I'm not seeing where it tells me how to find it.

Being able to change it in PurePath Studio is good as far as it goes, but I have to know how it is doing it basically in order to use it dynamically in a product.

Which chip are you using? We have different PPS for different chip sets.

We're using the AIC3254

Good day guys,

Is there any progress on these issues?

I am using Arduino Uno SPI to control AIC3254.

I want to select mux on the fly but dont know how the real procedure is...

As my reading So far, I just found how to change filter coefficients on the fly...

Any help would be much appreciated.

Thanks and Best Regards,

Hi Kal,

This information would be in the Component Interface section in the Properties window.

Thanks Justin!

I just feel that I know that to answer my question somehow is a bit tremendous. There are overwhelmed aspect to look at, such an adaptive mode, SPI aspect, driver, register aspect, procedure, buffer, and counting.... haha. By the way, I have solve the problem alhamdulillah by refer to page 22 of slaa404c.

simplified procedure:

1. select page.

2. write data of mux selection to register.

3. switch buffer.

4. repeat 1.

*note that processing block might be need to be configure first, in order to enable adaptive mode.

Just my two cents,

Thanks and Best Regards,

kal
