Take a look around Bruce's website, www.Rentron.com as he has a wealth of information on using Picbasic with infrared. The infrared serial communication article explains how to set up HWPM for different oscillator speeds to get 38kHz. I bought a few of his decoder chips, and he's great with sharing what he knows, as you'll see on his website. (The decoder chips work great, by the way!)
