Thread: printf formating!

Hi all,

I'm in the middle of type out an software from Keil compiler for '51 to IAR compiler for H8.
The issue is that I found:

Code:

unsigned char buffer[40];
unsigned char variable1, variable2;
....
sprintf(buffer,"%0.2d %2.2d", (int)variable1, (int)variable2);
....

I cant check whats the result of that statement in Keil compiler, but in IAR result is:

Code:

0.2d 2.2d

What has no sense. Any ideas?

Try just %d

I wouldn't bank on the standard C library for embedded compilers like the ones you're using to have FULL support for every single option within the ANSI-C standard.

I'm guessing that since it doesn't know about that extended format, it just copies it to the buffer.

I know now that IAR does not support %0.2d formating. In Keil it makes "08" from "8". So I have to write my own format function. Thanks for reply.
