Re: Not enough pins on EXPAND-B port for lab??

Subject:

Comments:
: : We have only 42 pins available on the EXPAND-B port. : : However in this lab, we need 23 address pins, 16 data : : pins, and 8 signalling pins which amounts to 47 : : signals (neglecting clock and reset). : : Am I missing something here? : There are actually 49 pins available. The pins marked DI1/99 : and so on are dual-use pins. During configuration they are : used to download the configuration bitstream, but after : configuration of the FPGA they can be used as normal I/Os -- : in the case above, I/O pin #99 for example. This is just : enough pins to do the lab. : Vaughn
