COMMUNICATION: HCS12 - RS232 - PC

Started by March 13, 2003
Hi,

i am using the HCS12 chip (MC9S12DP256) and I have to communicate through the RS-232 with PC. Be so kind and help me. I find any (C source) codes, which could get me started.

Thanx, Martyn

I assume you have a c compiler. The compiler already has the functions you
need.... you need to init the sci for 9600 bps operation, and you need a
function to send a character and another to receive a character... these are
putchar() and getchar(); So a simple first program might be

#include <stdio.h>
void main(void){
char c;

initsci();
while(1){
printf("This is a test\n");
}
}



Hi Martyn,

check out the example code in the ACPRD HCS12 reference design, it also
contains some SCI stuff:

Hi
you need to download the new version of the codewarrior V2 (free
trial version) from motorola site.Then when you have this version
you need to create a project with the processor expert it creats for
you the template with the beans. The next step is to add this
internal components and mark the beans that you want (SCI0 in your
case) then
look at the event.c file and AS1.c file

Try this and if you still have some trouble contact me again
