[opus] Trying to use Opus in an STM32F429IIT6 embedded project

[Ulisses Piassa]

Hi everybody,

I tried the solutions proposed and some more things, but afterall, I still
could not figure out whats going wrong...

Some developers told me to try using the "opusfile" library, but it seems
really complicated to port to my project.

So I'm back to the mark zero.

Here's an screenshot of the files I ported to my project:



[image: Inline image 1]
[image: Inline image 2]
[image: Inline image 3]

When I say "port", I mean "I put all the files that the compiler looked for
and generated an error for not finding them". If I want to use the "decode"
function, I put all the files which this function depends on.

Absolutely ANY help would be useful. If anyone can give me any clue, I'll
be really thankful!

Thanks a lot!

Best Regards,


Ulisses

P.S.: I'm sorry Jean-Marc, I'd just realized that I replied for you only,
and not for the opus list. My apologies.
