Interesting problem with programming BS2
Archiver
Posts: 46,084
Gentlemen,
I have a small problem when I am trying to program a BS2. I have not used
this setup in a while but the last time I used it, things worked properly.
Anyway, I am trying to program a BS2 in a circuit and I have all the same
equipment as last time (about 2 months ago). The cables are the same, etc.
It is the only cable I have to program these chips.
What is happening is when I go to program the chip, it 'shorts' it out for a
short period of time (the meter on the power supply goes to 2.5A) and then
it returns to normal. The chip takes the program and works properly before
and after.
The really interesting thing is that I got a new laptop (Dell) and it
actually has a com port, not strictly USB. When I just hook up the cable to
it, it 'shorts' out the power supply too. I cannot get it to work at all on
the new one. It 'shorts' the chip out whenever you try to program, or even
hook it up.
Does anyone have any ideas? I am stumped and I really wanted to use my new
laptop.
Thanks,
Mark

one will program a chip that is out of the circuit perfectly. The old one
will program the chip in the circuit, but it shorts the source out for the
period of time while it is programming, then works fine after that.
Question: Do the pins of the stamp revert to some default input or output
during programming?
The last observation is the new laptop (win 2000) shorts the souce out
immediately by just hooking up the cable.
I appreciate everyone's help on this one.

The pins are cleared and set as follows, upon reset of the Stamp. From page
numbered 47 in Stamp Manual Version 2.0C :
quote
When the BASIC Stamp is powered up, or reset, all memory locations are
cleared to 0, so all pins are inputs (DIRS = %0000000000000000). Also, if
the PBASIC program sets all the I/O pins to outputs (DIRS =
%1111111111111111), then they will initially output low, since the output
latch (OUTS) is cleared to all zeros upon power-up or reset, as well.

Regarding your last observation:
Did you check your boards connector (DB9 socket I presume)
Some times the socket pins get a bit worn out and if there
is a bit too much solder plugging in a cable could lead
to shorting pins to other tracks which could explain the
increase in current. Do check it out and wiggle your cable
and see (on the solder side of the connector) how the connector behaves.
Also check your cable, just to be sure.

Ok.. update. I have figured it out to differences in the laptops. The new
one will program a chip that is out of the circuit perfectly. The old one
will program the chip in the circuit, but it shorts the source out for the
period of time while it is programming, then works fine after that.
Question: Do the pins of the stamp revert to some default input or output

The last observation is the new laptop (win 2000) shorts the souce out
