ADAU1701 KABD-430 Configuration

Category: Hardware
Product Number: KABD - 4 X 30

Hello. I am new to both the ADAU1701 and Sigma studio. I am using the Dayton Audio KABD-430 with the DSPB-ICP1 In-Circuit Programmer. I realize that the answers I am seeking are likely buried in the wiki somewhere but I am in need of some (hopefully) simple assistance.

I have built a 2 way portable boom box with the KABD-430. After completing the wiring and a successful connection to the ADAU1701, I am realizing that the learning curve for Sigma studio is going to take me way, way longer to get my head around. This is a custom build for a customer and I am well out of time. The example projects are a start but I continue to be stymied by my lack of experience with Sigma. I am hoping that either a project in Sigma for what I need already exists or that someone could help me with the modifications.

It is a 2 way design with a desired x-over at about 3500 HZ. I have wired a switch (Pot 1 on the KABD) to select between the Bluetooth and Aux inputs per instructions. I would like Pot 2 to be a treble tone control and Pot 3 to be a bass tone control. Pot 4 is for Volume. That's about it. My difficulty is how to hopefully modify an existing sample project to these specs as I think a new project would take me even longer. All the example projects mix the bluetooth and aux signals (not desired) and I am wracking my head on how to reassign the pots. Hopefully if I can get that far I can figure out how to tweak the x-over to perfection.

I realize this question may seem I am asking to be hand-held through Sigma and perhaps I am. I foolishly assumed both that Sigma was more intuitive and/or I was more competent. Were it not for a diminishing timeline I would be happy to spend days and days to learn Sigma. Obviously my competence with speaker design does not extend to this level of IC engineering since my searches so far indicate a fluency in the language I do not possess. As this is already a verbose question I hope this is enough for someone to point me in the right direction and of course I will try to provide any other relevant information if someone is willing to help me out. I am loathe to admit it, but it should now be assumed that I am a bungling idiot with Sigma. I have spent more time trying to navigate Sigma than it took me to build, wire and finish the whole rest of the project and I am out of time.

I sincerely appreciate the assistance from anyone who has taken the time to read through this.

  • hello,

    I hopefuly get delivery of a my kabd-430 soon, and will be happy to choose your use case as a training use case on mine.

    I tkink I know how to do those on another board (1467) but I've seen differrences of cell behaviour between the two chips.

    So, I'll come back when I'll be able to bring you some example sigmadsp project 

  • Hello SloWave,

    A quick suggestion, if you want help in modifying your program you should include your program in the post. It is easy to do now, you can simply drag and drop it in the window when you are writing a post. 

    SigmaStudio is quick and easy to learn. You can get rather far in just days rather than taking years to learn DSP programming using C or other languages. Still, I understand there is a learning curve and I had to endure the same process. Then add the stress of a looming deadline it is difficult to relax and learn. 

    I hope your project ends up well.

    Dave T

  • H all, now I've taken delivery of my 1st kabd-430, so please @SloWave share your .dspproj so that we can have a look at it and help you !

    Cheers.
