User IO pin outs for Panda II

On the Panda II schematic why is J3 pin 37 called out as IO68 when it is labeled D52 on the board?

Same applies to all pins not just that pin.

The reason is a layer of abstraction here. The pins on headers are labeled Dxx or Anxx …etc. Those are the names found in the FEZ Panda dll.

If you are using the USBizi dll then you can use IOxx instead

Thanks - that clears it up.
