I've been using the codeSourcery environment through Anglia, but I've noticed that the code is getting a little big, because I've included sprintf and sscanf. Is there a way, short of writing my own versions, of getting a leaner version of sscanf and sprintf? Specifically, I would like to cut out the float support, if it would gain me some space.

Thanks.

hi,

anglia uses codesourcery toolchain. codesourcery uses newlib. I believe newlib either:

-can be compiled without float support for printf

-or includes a printf alternative without float support

check the manuals.

yes the anglia toolchain uses newlib.

It can be a bit bulky, you could reduce the size by using the integer only versions, eg. siprintf, iprintf etc. but they still use heap memory.

The best solution is to use one of the many free implementations on the net.
