Ready-made I/O for Digilent boards
www.digilentinc.com
The DIO4 Digital I/O board
provides a simple and
inexpensive ready-made
source for several useful I/O
devices and ports. It can be
used with the D2SB or D2FT
boards to provide a
convenient source of I/O
devices that are useful in the
design and debug of digital
circuits. All I/O devices are
directly mapped to I/O pins
on the system FPGA, so it is
very quick and easy to use.
