I've looked at several posts talking about shrinking the footprint of printf-like functions by setting #define switches in header files. There is also a "Tips & Tricks" segment about this discussed here. I wish to do the opposite. I want full floating point support for printf and scanf, but I'm running into problems making it happen.
First of all, here is what I have:
CodeWarrior 6.1 Special Eddition (Under "Help->About" it states the version is 5.9.0, Build 2404)
MCF51QE64 for my target MPU
Some other related threads that I have found useful are:
CW 6.3 for ColdFire and floating point
Simple Printf on CF question
As it stands by default, I can compile printf functions with the "%f" term, but nothing will be displayed. (I'm actually using sprintf and whatever putchar function I choose.) Also, printf works fine for printing integer values (%d, etc.).
I have tried adding print.c from "C:\Program Files\Freescale\CodeWarrior for Microcontrollers V6.1\lib\hc08c\src" and modifying libdefs.h from "C:\Program Files\Freescale\CodeWarrior for Microcontrollers V6.1\lib\hc08c\include", but I getting a lot of errors. Specifically in libdefs.h I include the switch "#define LIBDEF_PRINTF_FLOATING 1".
I think others have had success with this process before, but maybe there is a quirk for the Coldfire V1 that I am not aware of. I also wonder if I should be grabing printf.c from the HC08 source directory.
Thank you in advance for any guidance you can provide.
