capturing variable
Archiver
Posts: 46,084
I'm trying to communicate with an asynchronous device via SERIN and
SEROUT. It's communicating, but returns an unexpected result.
instead of giving me the expected 8byte ASCII hexadecimal string, I
get $7C. any idea why?
thanks for the help. Steve

instruction....
Since the BASIC Stamp stores everything as a number anyway, prevent
possible errors when sending ASCII characters by simply embedding that
character. Like this:
SendData:
SEROUT 9, 16624, [noparse][[/noparse]"S"]
And, according to my BASIC Stamp, the ASCII code for "S" is 83, not 82.

If I'm correct you are trying to receive 8 bytes. In that case
try the following. This code will bring in the 8 bytes. If you have any
questions please reply.

thanks for all the help, guys, I may be back at you in a day or two.

What often happens in cases like this, is that the instrument
responds too fast, before the Stamp is ready to receive. It takes
the Stamp a good fraction of a millisecond between the time it sends
the "S" and before it is ready to receive its first byte. But the
instrument may only wait a few microseconds. The Stamp has no input
serial buffer. When it is ready, it starts receiving out of sync in
the middle of the response.
In your latest experiment, it would "time out" because it tuned in
too late to get all 8 of the characters it is expecting. Even when
it times out, you can print the string buffer and see if there is
anything recognizable there. It might be garbled, but it will give
you an idea of whether or not my theory is correct.
The setup delay for a SERIN command with a timeout and using the STR
modifier is about 240 microseconds on a BS2sx, and a bit faster on
the BS2p. 600 microseconds on a vanilla BS2.

You were expecting back the string "7F0000000836A410<CR>", but when
you were only looking for one byte, you got $7f

modifier to put that string into scratchpad memory and save yourself
some space. To learn more click Help|Contents on the menu of the
Stamp editor.
It has been said that SPSTR only works with fixed length strings.
Well, I use it for variable length strings. You can e-mail me at
FrankSmith512@y... if you need to learn how to do that. I only
read a very small amount of the posts. E-mail will be your best bet.
Best Wishes,
Frank
