Can this be done with Basic Stamps?

Archiver

Bill-

This might be done with today's Stamps, but the overall scheme would
probably fit much more nicely into the new BSIIp (BASIC Stamp II
Plus, "planned for release in the first quarter of 2001").

- No Stamp has a "clock" per se in it. You can use pauses and delays
to stop everything for a certain amount of time and resume execution
later. The timing error with this approach is < 2%. There are
several clocks and timers available that can be conveniently
connected to today's Stamps to add on real timekeeping abilities.
The 1-Wire capability of the BSIIp adds several new clock options
from the Dallas Semiconductor line.

- No Stamp supports generation of parity bits for asynchronous
serial communication. A variety of baud rates and other parameters
are available. A Stamp could drive an external device (UART) to
solve the parity problem if necessary. Can you be more specific?

- You can hang an LCD and buttons on any Stamp to accomplish the
time setting or other programming functions via application
software. However, the new BSIIp has built-in LCD support for
Hitachi-based LCD's and would make this job much easier.

Hello to all,

I was wondering if an existing aging piece of hardware we
have can replaced with something fabricated via Basic Stamps.

The device is basically a timer that has an internal clock and
at programmable intervals sends text string commands out to
a 20 mA loop circuit.

So I need something that would:

1. communicate through the loop at programmable baud, parity, etc.
settings.

2. have an internal clock that could at least be settable via
a computer interface and ideally would have an LCD display
with buttons for setting the time.

3. send out text strings including characters like SOH (ASCII 1)
STX (ASCII 2), etc. From my knowledge of Basic, this part should
be no problem. But the strings would have to be sent at
programmable times.

4. For the mA loop in question, the loop current is supplied by
an external source.


Anyone who has any input concerning this please email me!

Thanks to all,

Bill Bartley
