Big pic for such a little job. You don't need a 48 Mhz crystal 20 would be fine. You'll have big problems with a 48 Mhz crystal
if you can't make a proper PCB for this. And a 18f4550 can't use a 48 mhz crystal any way it uses a 20 and Pll to get 48 mhz
But you don't need that if your not using USB.

I have a program that would do this but it's in Swordfish Basic
