    Default Usb-Pc connection 18f4550 pls help

    Hi,
    I have a project with 18f4550. I've read "USBDemo, something to learn USB a little bit" and learn lots of thing.

    Firstly I know visual basic (about at moderate level ) and my pic assembly is I think is enough.

    My project is that, I will write something on my pc program (max 8 letters.) And 4550 have to show is at 8 of 16-segment display (alphanumeric display). I have to use common anode and select the displays by transistors etc..

    In this case, I have to send 8 info for displays. But, I don't know how. Mr E 's sample is only for 1 information. And don't know how to give 8 informations from pc to 8 vars (I mean variables) I after that making a for loop (select display and show the letter ) at pic ( at the same time alive connection)

    It's too complicated. Please help me. Sorry for my bad English.

    Here is 1 way, not the only, I'm sure.

    Are they always the same 8 variables ?
    If so just use LCDOUT var1," ", var2," ", var3," ", var4 or something to that effect . . .
