Dear friends:
I want to send data to computer by USART of Atmega8 with Asynchrony mode. I=
write very simple program for sending data to computer and can see the sen=
t data by oscilloscope in pin number 2 of COM1 (serial port) of my computer=
. But unfortunately I can=E2=80=99t see sent data on the Terminal section o=
f CodevisionAVR Program or on the Hyper Terminals of Windows. I think the s=
etting of them such as Baud rate number of Stop bits, parity is correct.=20
Setting of Terminal:
Baud rate: 9600=C2=A0=C2=A0 Data bits: 8=C2=A0 =C2=A0Stop bits:1=C2=A0=C2=
=A0 Parity: none=C2=A0 =C2=A0=C2=A0Emulation:TTY
Main part of Program:
UCSRA=3D0x00; UCSRB=3D0x08; UCSRC=3D0x86;=C2=A0 UBRRH=3D0x00; =C2=A0UBRRL=
=3D51; //9600
top:
=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 UDR=3D=E2=80=99a=E2=80=99;=C2=A0=C2=A0=
=C2=A0=C2=A0=C2=A0=C2=A0=20
=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 delay_ms(100);
=C2=A0goto top;
Please Help me I should solved this problem AFAP.
Best regards.

How are you connecting the AVR to your computer?

Dear Ali,

for accurate serial communication you have to use external crystal
instead of internal rc oscillator.
with 8 MHz ones:
// USART initialization
// Communication Parameters: 8 Data, 1 Stop, No Parity
// USART Receiver: On
// USART Transmitter: On
// USART Mode: Asynchronous
// USART Baud Rate: 9600
UCSRA=3D0x00;
UCSRB=3D0x18;
UCSRC=3D0x86;
UBRRH=3D0x00;
UBRRL=3D0x33;
void char TransmitByte( unsigned char data )
{
while ( !(UCSRA & (1< er
UDR =3D data; // start transmittion=20=09
NOP();
while ( !(UCSRA & (1< r
}

You also need some sort of level translation. The easiest is something like
a max232, but there are certainly other schemes.

We have no idea what the original poster is using or trying to use. That's
why I asked the question. I didn't assume anything.

All we have is a snippet of code and the statement that he can't see the
data on Terminal section of Codevision AVR or Hyperterminal. Yes, some sort
of level translation is needed (RS-232 for a serial port, etc.) But until w=
e
find out if that has been implemented, or what has exactly, we can't really
do much to help.

We can always give the advise to not use Hyperterminal.

Use something else, Tera Term for example:

There is quite a bit of terminal software out there. Here's a few I like:

Netterm:

http://www.securenetterm.com/html/netterm.html

Real term:

http://realterm.sourceforge.net/

What is actually wrong with Hyperterminal?

It always worked fine for me, for what it does.
