Yes, you should be able to down load it.
Have you programmed the PIC18f4220 ?
I have an example file form MELabs that compiles
but when I try to program it it comes up with "code error at 0008"
I am wondering if it is my 40 pin ZIF socket on my programmer.
Is there one just for the 18f series . Mine is the one I have used
with the pic16f877 chips.
Thanks
Jim
