Hi there,

I'm using CodeWarrior 3.0 to compile my project for use on a MC68HC908JK1. When trying to debug my program, which does compile, I am inserting the printf() function and now my project won't compile.

Link Error: L1822: Symbol TERMIO_PutChar in file ...\ansii.lib is undefined

Could someone help me out by telling me how to get the printf to work.

Hi,

Just add the file termio.c from installation directory lib\HC12c\src to the project.

Hi Ron,

Thanks for tip but it opened up more problems,

now I am out of allocation space in segment ROM

I have stripped down all of my code trying to get this printf() function to work but there is still not enough room.

The ROM locations and size are:

$F600–$FBFF; user memory, 1536 bytes on MC68H(R)C08JK1.

As a follow-up to my last reply I am using a MC68HC08JL3 chip now for the sake of debugging. I plan to revert back to the JK1 once this is said and done.

So now there is enough ROM to compile but the True-time Simulator and Real-time Debugger is telling me I am using "invalid or unitialized memory" when I start my simulation

So now I've got two questions:

how to get printf() to compile onto a JK1?

AND

how do I get printf() to print to console (my screen)?

ANSI printf() take a lot ROM space. If your mcu is ROM limited
or use free SE CW HC08. Then you may code your won SCI utility like SendChar() / GetChar() / SendString()..

Check Compiler manual on how to generate compact code and
Manual_Engine_HC08.PDF -- P&E target interface for how to use full-chip-simulation properly.
