USBDemo, something to learn USB a little bit

[Squibcakes]

Yeah your right it is a battle!

Couple of things.,... I am finding that jumping straight into USB with these 18F chips may be a bit ambitious.

These 18F series do seem to be a bit more complex than your average 16F chips.

Just getting my head around the config fuses and using mpasm as opposed to using PBP Compilier is mind boggling but I think I got it.

At this stage I'm just trying to get the 18F to flash the LEDs and stuff LOL!

On another note, I tried to compile Mr E's usbdemo.pbp file and I get all soughts of errors. Any idea why? I mean the hex file works, but cant I compile his pbp file. I want to make sure that I can get the basics working first.

I tried tiny bootloader which apparantly supports 18F4550 chips but couldnt get it to work yet.

mmm, i suspect those usuals
1. upgrade your MPASM version
2. comment all default PBP config fuses in the 18F4550.inc file, AND if you don't have PBP 2.47, modify the LIST line to.....

        LIST p = 18F4450, r = dec, w = -311, w = -230, f = inhx32

once done, if everything is in the same directory, it MUST work!3

for the Tiny loader, i know there's some DEFINEs to add... wich? i don't know, i don't and won't use it.
