Datasheet

The Genesys 2 board includes eight slide switches, six push buttons, and eight individual LEDs. The pushbuttons and
slide switches are connected to the FPGA via series resistors to prevent damage from inadvertent short circuits (a short
circuit could occur if an FPGA pin assigned to a pushbutton or slide switch was inadvertently defined as an output). The
five pushbuttons arranged in a plus-sign configuration are “momentary” switches that normally generate a low output
when they are at rest, and a high output only when they are pressed. The red pushbutton labeled “CPU RESET,” on the
other hand, generates a high output when at rest and a low output when pressed. The CPU RESET button is intended to
be used in processor designs to reset the processor, but you can also use it as a general purpose pushbutton. Slide
switches generate constant high or low inputs depending on their position.
The eight individual high-efficiency LEDs are anode-connected to the FPGA via 330-ohm resistors, so they will turn on
when a logic high voltage is applied to their respective I/O pin. Additional LEDs that are not user-accessible indicate
power-on, FPGA programming status, and USB and Ethernet port status.
14. Pmod Connectors
The Pmod connectors are arranged in a 2×6 right-angle, 100-mil female connectors that mate with standard 2×6 pin
headers. Each 12-pin Pmod connector provides two power pins (6 and 12), two ground pins (5 and 11), and eight logic
signals, as shown in Figure 20. The VCC and Ground pins of can deliver up to 1A of current per pin. Pin assignments for
the Pmod I/O connected to the FPGA are shown in Figure 16.
