Re: silly question - toma...@hotmail.com - Nov 20 8:23:57 2008
Thnx, but im still confuse. I know i should use hyperterminal, but the thing is i dont know how to write the coding to print the output through hyperterminal. Or is there any build in print function like printf? Can u provide some example C coding?
Btw, im using CodeWarrior 4.6 compiler.

If you use ICC12, you have to write your own "putchar" function.=20
Then, you can use the internal function "printf", "puts" to write any thing
on your serial port.
With CodeWarrior.. I don't know how to write interrupt service routine...
I send you a mail with joined file I rewrite to your address
t...@hotmail.com
with
- init SCI1
- redefinition of putchar
- interrupt function for SCI1
Hope you'll receive it. Sorry, it's in French !
In your main function, you just have to
- call init function
- enable interrupt
- write what you want by printf or puts or putchar
Anyway, a compiler never can find by itself where you want to send
characters with printf or puts. The compiler simply call putchar function.
It's why you have to write it.
