Problem with serial communication

[zico]

I'm using CCS PCW compiler to generate code for serial communication for the PIC16F84.



#include "usart84.h"
#include


void main() {
char c;
// int8 i;
setup_counters(RTCC_INTERNAL,WDT_18MS);

printf("Hello ");
printf("Press a key: ");
c=getc();
printf("You've pressed: \%c",c);
}



The file "usart84.h" is as follows:

#include <16F84.h>
#use delay(clock=4000000)
#fuses XT,PUT,WDT
#use rs232(baud=9600,parity=N,xmit=PIN_A3,rcv=PIN_A2,bits=8)


The problem is :
The output is several time the word "Hello Press a" & some strange characters...
My question is :
How the computer & the PIC insure the synchronization???
Why the PIC is not reading the character? by getc()????
10x for ur responses.

<font face="Courier New" size=-1>Try doing these two things:

1. Remove the Watchdog timer from your program.

2. Put a while(1); statement as the last statement in main().

Hello.
10x a lot PCM programmer, you are absolutely right.
I simply deactivated the WDT, & that's it.
It's not looping.
Bravo.
