The program is compiled good but the datas sent are strange characters and the ones in the program.

Might come from this part ?

#include <16F877A.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use ...

printf( "\r" );

This is not working too ...

But there's something strange because the program seems to work with the CCS PCM C Compiler, Version 4.013 and doesn't working with ...

I'm using a PIC 16F877A and I try to send a command "0x0D" on the rs232 but it's not working.

My program is

#include <16F877A.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay ...

You're right PCM Programmer, the problem is coming from the resistors.
Thank you so much again.

I'm using a PICDEM 2 Plus Demo Board with a PIC16F877A and I made a program to write on the 24LC256 eeprom on that board.
It's working very fine but now I made a circuit with another 24LC256 only and ...

I tried to change as you said to me but I stil have the same problem of display on my computer.

Can you please explain to me what is the polarity reversed ?

I have a problem when I want to send some characters from my Picdem 2 Demo Board with an 16F877A pic module to my computer via the rs232 com using the hyperterminal application.

The characters I'm ...

It's perfect !

Thank you for everything Mr PCM Programmer !

I'm downloading the manual now and then I think that I'll be able to program without bothering you all the time.

But I have one when I want to display a value ...

The version I found in the LST file is :

So let's see that tomorrow but anyway thank you so much for your help !

Best regards,

I've changed the line :

#include <16F877A.h>

But I still have the character after.

The PIC I'm using is a PIC16F877A-I/P if it can help

The Quartz is the one on the Picdem Board ---> JWT 4.00/5V MHZ and the PIC I'm using is a 16F877A
