hi,
1.i want to make a virtual serial data by proteus virtual terminal,i place a virtual terminal block,join it to mega32,also i use max232 between them,but after max 232,from mega32 to output(virtual terminal) no data transmit
2.how do i make my favorite data* to send it for micro as e virtual data?
 
favorite data:a packet of data include 300 byte per second.

please help me.

The Virtual Terminal in ISIS doesn't need a MAX232 driving it - you'll be 
giving it inverted data, but there was a bug in the Mega16 and Mega32 models 
at some point recently, causing the UART to transmit rubbish.  I think I 
reported it to Labcenter.  I'd suggest trying a Mega644 without the MAX232.

I'm going to learn ATMEL AtMega8535 programming, so I bought:

STK-500
AVRISP MKII
1 breadbord
2 books: programming and customizing the avr microcontroller + Embedded C 
programming and the atmel AVR

What do you think if I use IAR Embedded Workbench as C compiler ?
What version ?
suggestions

Riccardo

Why not use the infinite value Studio plus gcc (which is available as
WinAVR)?

That will be VERY EXPENSIVE once you run out of what the
free demo can do.

AVRStudio and winAvr (as Jim already commented) are both free
and reasonably good.

A Mega8535 40-pin plugs straight into a STK500 and can be programmed via a RS232 port. So you may not need that AVRISP MKII. With this the 8535 and other chips can be programmed via a USP port.

The book "Embedded C Programing and the Atmel AVR" at one time came with the evaluation copy of CodeVisionAVR, and it probably still does. cvAVR is a very good C language compiler, especially for newbies. The CodeWizard that comes with it is great also. The only restriction is the code size is limited to, I believe, 2K. But that is enough to get you well into using the AVR family of micros.

I find that GCC (WinAVR) (and free) plays well with AVR Studio.  So far it
has done everything I have asked it to do.

I also use the AVR Ice Cube JTAG device
(http://www.ecrostech.com/AtmelAvr/AvrIceCube/index.htm) but I guess you
have the MKII for that.

I appreciate that, but there isn't much difference in the UARTs anyway.

I've just done a quick test and all is well as far as using a Mega32 with
the virtual terminal in ISIS.  I'm using the latest beta version (7.6 beta
4).  Whether the bug exists in the last full release, I don't know (7.5
SP3, I think).
As I said, though, first lose the MAX232 as far as driving the VTERM, and
don't forget to set the Mega32 properties correctly.
