Ok I was thinking of a little project to test the old grey cells and to finally how to learn how to use USB as i am planning to need it soon, and sooner jump into a big project this seems easier....


Set usb on the pic to appear to windows as a virtual com-port


if available, read a character, from the virtual com-port, convert it to upper case, and then output it at 9600 via the hwuart....

and....

continue till the worlds end.

Now its all simple when written down, and i can easily achieve this if it was using the hwuart and a swuart, but i am lost with the usb side.

I think i'm in the same boat as alot of people on this, so can we do this simply, if usb is such a thing.....

I know there are lots of easy this and that and HIDeous things around, but the keyword is simple.....

Got a spare 18f2550 and a 4mhz crystal here i think may be just the ticket
