NG RS232 Tutorial ..... How To monitor the data ?

[aljamri]

Hi,
I'm doing NG Tutorial 7 which uses RS232, using USB to RS 232 converter cable and wants to know, which PC program can I use to read/manipulate the RS232 I/Os ?​

Thanks

Just use the hyperterminal that ships with windows

That USED to ship with Windows, but not since XP.

You can easily transfer a copy from XP if you have an XP machine though.

Failing that, there are plenty of free terminal emulator programs around.

@ Nigel sorry I have the professional version... I didn't know basic XP doesn't have it.... @aljamri Download teraterm https://hp.vector.co.jp/authors/VA002416/teraterm.html its free

I think you've misread my post XP DOES have it, but neither Vista or Win7 do - I copied Hyperterminal from my old XP machine to my new Vista one.

Now I'm cuffuffled!!!! I have vista AND windows 7 home premium at home and both have hyperterminal on...

My Windows 7 Home Premium laptop doesn't have hyperterminal...

Did you put it there?

Here's the Microsoft bulletin about it:

I don't remember putting it on!!! I use it to debug my C# projects via "com0com" I link hyper terminal to both ISIS and visual studio....very strange....

"I wonder if Visual studio installs it!!!!"

I believe it installs LOT'S of stuff, so you never know?.

 

[Mike - K8LH]

Well I've got Visual Studio 2010 installed on that same Win 7 Home Premium laptop and still no hyperterminal...

 

[Ian Rogers]

Right... at home now... It was installed BY ME!! just after installed micro.net (senility moving in) Sorry about that everyone!!

You can also use e.g. the python programming language with the pyserial or pyvisa libraries to talk to RS-232 devices. Get portmon from sysinternals to look at the stuff that goes on during RS-232 transactions, as it can help debug things sometimes.

Thnks for all, Ive found several alternatives, used them and have no response, only getting "0x00" which indicates no data recived. I've used N.G. first circuit in
. Is that fine or shall I use the second circuit in the same page?
Thanks

 

[Nigel Goodwin]

Either will work, they are essentially the same, just providing one or two sockets.

 

[aljamri]

Thanks Nigel,

I was much worried about the MAX 232 connection because I've read some where that it has two converters, one software and the other hardware, so that I thought I'm using the wrong one.

One step on the right way achieved, My PIC (16F628A) got connected into my PC (windows7), using very light software called Terminal the attachment shows a screen shot of sent and received data using the underneath code found in Mikro C help for USART.

EDIT: here is the link for Terminal:
https://www.opend.co.za/software/terminal/index.htm

unsigned short i;
 
void main() {
 
// Initialize USART module (8 bit, 9600 baud rate, no parity bit..)
Usart_Init(9600);
 
do {
if (Usart_Data_Ready()) { // If data is received
i = Usart_Read(); // Read the received data
Usart_Write(i); // Send data via USART
}
} while (1);
}//~
