Hi, I am trying to use sprintf function but my code syze overflowed with 19k.
So is there stdio pack of functions which is the bare minimum of code. My only goal is just printing to string.

In the first place, if you do not need to sprintf floating point values, then you could try setting the define "CR_INTEGER_PRINTF", as described in the FAQ:

http://support.code-red-tech.com/CodeRedWiki/UsingPrintf

If that doesn't reduce things sufficiently for you, then you could take a look at the "lib_small_printf_m0" that NXP provide as part of their LPC1114 examples for LPCXpresso. This is a port that NXP have done of the "small printf" that can be found at:
