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 |

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: http://hc12web.de/acprd On Thu, 13 Mar 2003 10:40:01 +0100 Martin Hone <> wrote: > Hi, > > i am using the HCS12 chip (MC9S12DP256) and I have to communicate through the RS-232 with PC.

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 Uri --- In , Martin Hones <martinhones@s...> wrote: > Hi, thank you for your reply. > I cant find any beans you wrote, please advise me.. > Martin > ----- Original Message ----- > From: uripeled2000 > To: > Sent: Sunday, March 16, 2003 11:34 AM > Subject: [68HC12] Re: COMMUNICATION: HCS12 - RS232 - PC > Hi > I had the same problem Try to use Version V2 of the Metrowerks it > has automatic beans that start it for you.If you can't find > contcat me I will help you > > uri.peled@s... > --- In , Oliver Thamm <othamm_yahgrp@h...> > wrote: > > Hi Martyn, > > > > check out the example code in the ACPRD HCS12 reference design, it > also > > contains some SCI stuff: > > http://hc12web.de/acprd > > > > > > > > On Thu, 13 Mar 2003 10:40:01 +0100 > > Martin Hones <martinhones@s...> wrote: > > > > > Hi, > > > > > > i am using the HCS12 chip (MC9S12DP256) and I have to > communicate through the RS-232 with PC.
