"That's just too cool!"

- Isn't it?   :)



"Have you got a link (or links) for that?"

- Tadaaa!

"What's the physical connection between PIC and PC?"

CAUTION: SPAM ALERT!!!

- That can be anything you want.  You can use the PIC 18F family which now
integrates USB communication.  Mécanique has just released Easy HID which
generates default software template for the PIC and PC through a GUI
interface.  Check it out:
<http://www.mecanique.co.uk/products/usb/easyhid.html>

- But wait, that's not all, you also get access to a budget-priced unique
Vendor ID for your USB product.  USB.ORG has strict compliance requirements
before assigning a Vendor ID which costs between $1500 to $2500.  You can
avoid all that and use Mécanique's Vendor ID and get 10, that's right, -->
TEN <-- Product IDs for the low introductory price of £29.95.

"How big is the FATxx driver code on the PIC18F?"

- Check out the stuff I've uploaded in the Files section, USB folder.  I've
uploaded 2 folders that I generated using Easy HID.



So with a slave PIC 18F4550 you can interface with the PC via USB and manage
a smart card all at the same time.

If you will not market your product, you can leave the default Vendor and
Product ID generated in the code.
