Yes, you need a crystal, and two small capacitors (or use a ceramic resonator, with the capacitors built in). You can use a simple RC (resistor capacitor) external oscillator, but it's not very accurate - best to use a crystal.
 
ok here we goo.>!!

well i brought a 20Mhz crystal 6euro's..!!

and 2 very small capacitors (33pF???)

wired it up and then i saw that i was in plan suplying the VDD to pin 10 instead of pin 11 :cry: :shock:

soow now i have to wait to repait my sucker..!! jeejje :lol:

I use the P16PRO40 with my own software, WinPicProg.

ok but can you also program the pic18FXXX???

No, I've never had any interest in them, WinPicProg basically supports the chips I use - after all, it was written for my own use :lol:

IC-Prog is pretty good, and is free as well - I don't know if it supports the 18 series chips or not - I've never had occasion to look.

What I would like to do is buy a PicStart +, but I can't justify the money ( I have around 200 16C57XT's that I can't use ).

that one is standard for my programmer..

Right, you have the picall programmer (not just the software), I've considered ordering one as well - just for the 16C57 - but I don't know what I'd use them for :lol:
