OpenPCD is a free and open RFID reader reference
design platform. The OpenPCD firmware is software
that runs in OpenPCD's AT91SAM7 ARM controller,
and connects the RFID reader hardware (CL RC632
ASIC) with the Host PC via USB. The Firmware
includes a custom USB device stack and drivers for
the various embedded AT91SAM7 components. The
firmware itself does not run on Linux, but it only
works with a Linux host PC talking to it.
