timing problem

Archiver

Here's one for timing gurus:

I need a 38.5 kHz clock for a subsystem that a BSII is controlling. While
the Stamp is running a very simple program, can I use it to also generate
reliable clock pulses at the above rate? What considerations are there, and
what tolerance on the rate can I expect?

Thanks in advance?

I've been using a 555, but I'm hoping for a method that will be more precise
without having to make pot adjustments.
Besides, the 555 is pretty sensitive to temperature, no?
