Is it possible to avoid using snprintf in TouchGFX. Is there any alternate method available to copy values in the buffer and display it without using snprintf.

I'm assuming you mean Unicode::snprintf() (which is a TouchGFX function). Why don't you want to use it?

Hi Martin,

Yes Unicode::snprintf(). I don't want to use that because snprintf uses dynamic memory allocation. There might be changes for creating memory fragmentation right? also due to performance issues.

did you ever get an answer? I have a similar question. For other embedded applications with limited processor power I used a simple int-to-string function. I was displaying a lot of fast-changing numeric data and the library functions were too inefficient and big.

No, I didn't get an answer yet.
