PIC18F2550 simple USB function

[chris414]

I am reasonably familiar the basics of a PIC18F2550 microcontroller, but am struggling with the USB side of things. All I need to be able to do is turn an LED on and off through a piece of software on my computer, using the USB connection. Has anyone seen any good tutorials out there?

Look up USB BitWhacker

UBW (USB Bit Whacker) Project

Which already does pretty well just what you want, and lot's more.

The really long way around, is to download MPLAB, MCC18 student version, latest Microchip USB stack, and the Microchip Solutions folder for some pre compiled USB demo code. There is a demo in there that does just what you ask, worked great for a 18f14K50. Don't see any projects defined for the 18f2550 though.
