serial to parallel converter
Archiver
Posts: 46,084
Is there a way to program a serial to parallel converter with a BS2? I
have tried using serial in, but it's 8 bit limit is a problem. This is
just a simple R&D project that will be torn down after it's built. I am
trying to pick up and decode a serial signal that might be up to 16 bits
in length, not including start & stop bits and I would rather not buy
hardware if I can program it in software. I realize this may require
two word variables and the baud rate is somewhere near 968 baud. Thanks
for your help.

Hope this helps. It includes hardware and software. You can run the tests
he mentions at some standard baud rate that a simple terminal program can
be set for, then when you're satisfied it works, change the constant in the
BS2 program for 968 baud.

great, I have another project for those. Has anyone seen a good PC
based digital scope? I ran a search on google for 'digital scope' and
just about passed out from all the hits. Any good ideas here? Thanks
for your suggestion Jim.

You might search the Stamp list message archives. I think maybe Al
Williams held forth at length on this topic maybe a year ago... unless I'm
confusing the Stamp list with an article in Nuts and Volts. He probably
did both.
A Google on "+PC +digital +scope" produces a lot of hits, but they're one
heck of a lot more focused than what I saw without the +PC. I saw some
good relevant stuff on the first page. (The +'s force ALL words to be
present vs ANY word.)

Off the topic a little bit: almost sounds like the baud rate I use in much
of my serial and SPI routines: my main timer tick rate in most of my
projects is 1.024 mS which is 973 Hz. I so all of my background processing
during those ticks (including communications) - thus that odd rate.
Not an answer to your question but I thought I'd mention one possibility
for that particular baud rate.

Hehe, nah - it's good to see that someone actually found stuff on my site
useful. :-)
I'm slowly getting bits and pieces together for some of the unlinked ideas.
I have the parts for the bidirectional serial/parallel bus, so will
hopefully get that up and running soon. Will also play with a 16 bit bus
(which is easy to send/receive with the Stamp's shiftin/out command).
Also, the AM/FM Tuner controller is a project I definately want to get under
way. Just not sure if I should do the Frequency Synthesis with the Stamp or
the Motorola Chips I have.
cheers,
