Unable to interface USART with hyper terminal.

[Rahul]

Hey i am connecting PIC16f917 with hyterterminal using USART. Its running fine on proteus and virtual ports with hyperterminal. But when i am actually implementing its not running. I have also tested the cable by ‘LoopBack Test’.

 

Here is the code.

 

#include<pic.h>

#include<string.h>

 

void main()

{

 

// OCILLATOR FREQUENCY

SCS=1;

IRCF2=1;

IRCF1=1;

IRCF0=0;

 

//  USART INITIALISATION

SPBRG=25;

SYNC=0;

SPEN=1;

BRGH=0;

TXEN=1;

CREN=1;

 

while(1)

{

TXREG=72;

while(TXIF==0);

TXREG=73;

while(TXIF==0);

TXREG=32;

while(TXIF==0);

}

}

 

 

Its a simple program, just for testing.

 

Plz Help.

How u caclulate the baudrate.. i think problem in baudarate

[Anonymous]

I have reffer the Datasheet and selected the baudrate from there. SPBRG=25; for baud= 2400. I am using MAX232 can the problem be in it??…..And also i am using controller in DTE mode and expecting hyperterminal to work in DSE mode.
