sprintf for CCS 6.0

Matthew Chiang

Hi there,

I'm having sprintf problems with CSS 6.0 with 5.2 compiler. I've read some of the solutions but they seem to apply for version 4. I was wondering if there were solution for the latest CSS.

Thanks

Have you had a look at this wiki page? The concepts are equally applicable to all versions of CCS.

One of the most common reasons for printf family of routines to not work is insufficient stack and heap sizes.

Thanks. Shouldn't you set aside enough stack/heap size by default so this wouldn't be an issue?

There is usually a default stack and heap size set by the tools, however that may not be sufficient depending on the needs of the application. This wiki page contains some additional information about stack and heap requirements.

Where is the tcf file for my project? I can't find it anywhere. I'm trying to edit the stack for the DSP/BIOS section.

Is the tcf file not visible in the Project Explorer view? If it is a linked file and not physically in the project folder, you can right-click on the file in the Project Explorer view, go to Properties and click on Resources to see the location of the file.

I'm sorry but I still cannot find it.

Let's use this blinky example. This is my view in the project window:

Where is the tcf file hidden?

This example is not a BIOS project, hence does not have a tcf file. A .tcf file only exists in BIOS5 projects. For non-BIOS projects, you can set the stack and heap sizes by going into Linker settings as indicated here.
