Generating 38 KHz tone

[jumpjack]

I do I generate a 38 KHz square wave with a PIC?
Is it just a matter of turning on/off a pin 38000 times per second?
How do I set precise timing?

Yes, that's all it is - check my IR PIC tutorial for an example.

thanks.
in the meantime, maybe you're interested in taking a look at my post about IR remote controls replication:

It's part of a larger tutorial:

You should be able to learn how to code into your pic just ANY remote of yours.

Thanks, but I've been doing that for many years
