SEROUT Code to Hyperterm

Archiver

Hi,

I have a setup where there is a pin on the stamp, pin 8, that uses the
serout command. The command is supposed to send out a variable to
hyperterminal. However, this does not work. I get nothing in to
hyperterminal.

1. First off, is the baud rate 9600?

2. Second. . . what is the exact code I would use to send a variable
byte out of pin 8 so that hyperterminal can read and display it?

3. If I end up doing this wirelessly(TWS and RWS 434), should I still
send a synch and junk bit with the information if there is no stamp at
the other end?

Thanks a lot!

Baudd rate is 9600. You have to serout on P16 to go to Hyperterminal via the
serial cable.. Be sure Stamp Editor is turned off to free up Com1.

One more thing - I use Hyperterminal to control my model train. If you have
any querstions regardding communicating with Stamp from Hyperterminal let me
know.

I am currently working on and making a lot of progress with my GPS guided r/c car and airplane. The system uses the serin and serout command and I used the good old dos program called Telix to view the results of what I was getting from the GPS serial connection before I did anything else. It is an ultra simple dos program and a download site like www.download.com or www.shareware.com will have it for free. It will let you see what the stamp is outputting with no problem, I tried using hyperterminal and could not get it to work correctly even with the proper baud, parity and stop bit.

Just fyi.

The first thing that may be tripping you up is the modifications that need
to be made to the serial cable. See the stamp manual under 'serout' for a
detailed explanation.

The second thing that may be giving you problems is that physically pin 8 is
actually P3 (I/O #3) as far as serout is concerned. See page 200 (v1.9) of
the stamp manual if you are confused by this.

Here is code that will send out data on pin 8 (P3) at 9600 N81:
byteMe var byte
byteMe = "A"
serout 3, 16468, [noparse][[/noparse]byteMe]

If you wanted to send data on P8 (physical pin # 13), use this code:
byteMe var byte
byteMe = "A"
serout 8, 16468, [noparse][[/noparse]byteMe]


Also, someone suggested using P16 (if you have the carrier board). This
might give you problems because of the stamp resetting itself with the ATN
line. You'll need to make modifications to the cable once again. See the
figure I-17 and the 'serin' command in the manual (v1.9) for the why's and
how-to's.


To answer your third question ... I have no clue, never used those devices..
