Howdy stampers,
I plan to still kinda watch list for a while but
since the stamp doesn't have interrupts, I had to
try another chip for a project and now I'm totally
sold and probably won't be doing too much stamp
stuff. Thanks to all here for help and it was great
having Al Williams around to answer questions.
Best regards,
Bandit

········Would youlet me know (off list) what direction you're heading as far as a chipwith interrupts?· I'm very interested and am considering optionsmyself.
Thank you,
Tim

heavy load out there in the world and it has to be reliable when it does a
pbasic command. Interrupts must be done under a control condition. To do an
interrupt in the middle of a command can in some cases mean trouble. You
could lock up your control sytem causing an operation not desired. Second,
the polling interrupts on the BS2p only become active after the pbasic
command has been completed. This way you, the programmer, know that the
command was completed when an interrupt occurs and the next command resulting
from the interrupt was defined clearly in the program software. Third, the
pbasic commands allows the polling interrupts to be locked, if desired, and
the interrupt I/O pin causing the interrupt is stored in stamp memory for
programming input use. All pins can be interrupt I/Os which more than
available on a PC.
The BASIC Stamp is a simple reliable device and will always work well if its
design and firmware logic remains simple. I think time will prove this out.
