Hey guys, was wondering if I could get a little advice?
I've just been looking up a way of using a PIC for USB connectivity from the following page...(https://www.waitingforfriday.com/index.php/Building_a_PIC18F_USB_device).
The project uses the 5v from the USB to power the circuit, thing is I'll have a lot of other things going on and was wondering if I could simply build the circuit linked above without drawing power from the USB port and use another source to power the circiut. So basically, will the computer still be able to communicte with the pic without drawing power from, and sharing a common earth with the computer?
I'd really appriciate any ideas or advice.
Cheers
Martyn.
