Hi everyone,
two things today,
1/
on a bs2p-40 there are 32 i/o pins. Do you set dirs:
Mainio
dirs=0101011010101010
auxio
dirs=0101011010101010
or do you do it as 1 32bit number?
2/
i am currently working on a new project based on the bs2p-40 chipset,
i would like to try and build future proofing into the design ready
to accept the next generation of stamp chipset. Can someone indicate
to me the number of i/o pins the device is likely to have?
Regards
jon millard

Since stamps are based on a PIC internally, you can probably predict what
the next generation stamp looks like from the current-generation pic.

1) The Stamp only deals with 16-bit numbers, so YES, the method you're using
to set DIRS for all 32 pins is correct.
2) The BS3 is very likely to have the same format/footprint as any of our
BS2-24 series modules. It is very advanced, uses new technologies not seen
before and -- in a word -- rocks! Be patient, though, getting it finished
and to production may take us a while. As a long-time Stamp user (I bought
'em for eight years before I got hired), I can tell you that the wait will
be worth it.

That is correct, except for a small syntax change, %:
DIRS=%0101011010101010
