Wishbone LPC Bridge Samples:

1. pci_lpc/     PCI to LPC Host Controller using the Enterpoint Raggedstone1 FPGA card.
2. lpc_7seg/    LPC 7-Segment Display Peripheral using the Raggedston1 FPGA card.

To use these example, you will need two Raggedstone1 boards.  The first board is the PCI to LPC host, and the second board is the LPC device.  The two Raggedstone1 cards are connected together by making a short ribbon cable using 16-pin DIP IDC connectors.  The topmost pins of JR1/JR2 is where this cable plugs in.

The LPC bus is pinned out as follows, on JR2:

W1 LPC_CLK
W2 LFRAME#
V5 LAD<0>
U5 LAD<1>
V2 LAD<2>
V1 LAD<3>
U4
T4 LPC_INT (active low, not used by 7-segment peripheral, pulled up in host)

If you only have one Raggedstone1 PCI card, these designs could be combined and run on a single card.
