Re: ADC solutions for real time parameter control?

Right, I see, I will look into that, I hadn't heard of SAR before. Thanks.

Inside our office? We would probably use VS1005 instead of VS1053... :D
Ah... does the VS1005 have inputs for connecting sensors like an analog potentiometer? I only see ADC inputs dedicated to audio on http://www.vlsi.fi/en/products/vs1005.html, or perhaps I'm overlooking something?

Re: Standard C libraries not found

By the way, another way to run Pure Data on a platform that can run native code is libpd: http://libpd.cc/about/ It might be less suitable for a relatively minimal embedded situation like the VSDSP chips though, that's hard for me to tell. In any case, I think it would be great to have the combinati...

Re: Standard C libraries not found

VSDSP supports the original Ansi standard C. Not C99, C11 or other extensions Ah, I see. Yes it looks like Heavy (hvcc) is dependent on these newer extensions. If you think it would be at all feasible to implement Heavy on your hardware, then yes, I think it would certainly be worth taking a look a...

ADC solutions for real time parameter control?

Hi all, I am curious whether there are known/typical solutions to connect several (for instance 4) analog potentiometers to a VS1053 to control DSP parameters in real time; so with high resolution (10 bit/10kHz) and low latency. Perhaps an ATTINY402 connected via UART could be used for this? Thanks.

Re: Standard C libraries not found

Meanwhile, I've come to understand that VSIDE only has a limited version of the complete Standard C library installed - I wonder to which degree it would be feasible to extend this. For now I will focus on getting back into programming directly in C.

Standard C libraries not found

Hi all! For a music effects project, I'm looking into using the VS1053B. I'm especially interested in using the hvcc framework for running C code that is designed with Pure Data. I have done some initial testing and am running into a somewhat weird bunch of errors, namely that several Standard C lib...
