MATLAB Central Newsreader - Using custom code in the C2000 target

Using custom code in the C2000 target

Kevin — Tue, 08 Jan 2008 10:25:05 -0500

Hello,

I have to use the C2000 target for a project. I *think* I am
getting used to the simpler blocks, but now I would like to
re-use some code I wrote on CCS before. This code should be
called on a timer interrupt.
How exactly can I do it? I've read that you can do it in
Real Time Workshop, but I am still new to all this I don't
know if I can use both RTW and the C2000 target together. Is
it possible?

Are you asking if you can integrate previously-written C-code with your new
project? If so, you can do this using a variety of legacy code mechanisms.
Start with Legacy Code Tool, which you can read about in the help doc:
>> doc legacy_code

Thank you for your answer

So, if I have a piece of code written in C for the C2000
that I want to call on an interrupt:
- I convert the code to a s-function using legacy_code
- I make a mdl file with the "hardware interrupt" component
and the "RTW s-function" component

Am I right?

Absolutely, that is the right way to go about it.
