If you have been using LDmicro for quite some time, you should know that you can generate a 1s clock with any crystal.

A 20MHz crystal works much better.

Use the 500ms TCY instruction or the TON/TOF instructions.

I would strongly advise AGAINST a 38.763 kHz crystal because the clock frequency is far too slow to do anything with LDmicro.

For precision over very long periods (days or weeks), I would use the 50 or 60Hz mains frequency on a IOpin.
