servos with a bs1

Archiver

Could some one tell me if I can use a BASIC Stamp 1 to run four
servos? I know that a bs2 will work but I would rather use a bs1 due
to the low cost of a bs1.

thank you

You can, but you won't have a lot of processing time left over between
updates. At worst case, you'll have to send four 2-millisecond pulses,
consuming a little more than 8 milliseconds and leaving you with about
12 milliseconds to work before your next servo update.

Of course, these are simple numbers, and are fine as servos aren't too
picky. If you're clever with your code you should be fine. The key is
NOT to use PAUSE in your servo update -- allow your program code to
consume that time.
