Problem with serial communication
PostPosted: Tue Mar 14, 2006 10:26 am     Reply with quote

Hi everybody;

I am trying to send data from pic16f877 to pc by using rs232.I use hyper terminal.I can send data but there is always a delay.After oppening any file on my desktop i see the data.Data is correct but as you can see i can only get the new data after opening a new folder/file/explorer page with my pc.

I used
[code]
#include <16F877.h>
#use delay(clock=4000000)
#fuses NOWDT,XT, NOPROTECT,NOLVP
#use rs232(baud=9600,parity=N,xmit=PIN_C6,rcv=PIN_C7,bits=9)
.
.
.
long value=0;
value++;
.
.
.
printf("%ld\n\r", value);
[/code]

[quote] baud rate is9600
data bits:8
synch none
stop bit 1
flow control none[/quote]
I set character delay to 100 ms at ASCII settings. And i tried the same things on another computer.The results were the same.
why do you think this problem occurs.Thanks for your help.
