Basic stamp programing
Archiver
Posts: 46,084
Hi, I'm making an automatic paper cutter and will be using a basic
stamp to control it. I was wondering if I could save $50 by just
putting a serial port on the paper cutter to program it instead of
getting the $50 programming board? Or does the programming board
have special circuits required to program it?
Thanks

power to the Stamp and a serial cable.

that there are a couple of caps in the serial connection and two the
pins are tied together so the editor can do a loopback test. We have
schematics for our various demo boards; any will give the correct
connections to build your own serial interface.

serial connector and a serious 5V regulator built onto the board along with
the core BS2 components. It costs about the same as the standard BS2-IC,
and the components are all through-hole which makes it easier form many of
us to repair it or integrate it into other equipment.

More pins are indeed nice but not mandantory........If timing is not
critical, using three stamp pins you can have those 3 pins control 8, 16, 24,
32, 40
or more output pins.
There is s shiftout command and a 7hHC595 serial shift register, and there is
stamp code already written on the web sight. You can do the same with a
74ls299 which can be used to expand input AND output ports.......use shift in
and
shift out..

I always include a 4 pin header aligned with pins 1-4, on all my boards, this
makes changes much easier.

port, 8 high current outputs to control valves, motors, etc. and 7
additional inputs for sensors, switches, etc. along with LED's to show the
status of the outputs to make programming and troubleshooting easier. Check

I/O. Much cheaper. If you need the speed of a p40, that is a different
matter.

(one in series, one in parallel -- see the
parallax schematics)
which is used to reset the BS2 so it can be
programmed. You can omit them, as long as you
have control of the 'DTR' line (this is the
232 pin 4, which goes to the 'ATN' pin.)
Then in your circuit you'll only need to
add the 4 pins mentioned earlier
(GND, TX, RX, DTR) AND a 'loopback'
wire on the DB-9 adapter, to program the
BS2 in-circuit.
If you are using the Microsoft COMM control,
set DTREnable to FALSE so it won't hold the BS2
in 'reset'.

I know they've been described by several as "for communicating with
PC". But what exactly do the 2 caps do? And what happens if the
series cap is shorted or parallel cap is opened?

One is a coupling capacitor, the other a bypass cap. If the coupling cap is
bad, no serial comm. If the bypass is bad you might get erratic operation due
to noise.

level on that line (a series cap will block DC, but allow a transition
to pass -- this is how the Editor resets the Stamp for reprogramming).

What exactly does each of the two caps do on ATN pin?
