• Connecting an HDMI/DVI, VGA, or DisplayPort monitor shows a demo image with a mouse pointer.
• Connecting a USB mouse controls the mouse pointer on the display.
• The OLED () shows the Digilent logo and various information on several pages. Advance between pages with the 

BTNC button.

• The internal FPGA temperature, voltage and current readings of various power rails are shown on the OLED ().
• Connecting the board to an Ethernet network will acquire link, IP address and become “pingable” at the IPv4 address 

displayed on the OLED ().

• Connecting the USB-UART port to a PC and opening a terminal (115200, 8, N, 1) shows status messages.
• Pushing BTNU records audio off the microphone input for five seconds and plays it back on the headphone output if 

BTND is pushed, or line-out if BTNL. Similarly, BTNR starts a recording off the line-in jack.

• The LEDs are showing a scanning light bar.
• The fan starts when FPGA internal temperature reaches 60°C and stops when it drops back to 40°C.

To develop new FPGA designs for the Genesys 2, download and install the 

Xilinx Vivado® Design Suite

(http://www.xilinx.com/products/design-tools/vivado.html)

. The tools include all the USB drivers for the board. Once installed, the USB 

JTAG and USB UART ports can be connected to the PC and making the FPGA visible in Vivado Hardware Manager. 

Additional resources can be found on the Genesys 2 Resource Center. 

The Genesys 2 board can receive power from an external power supply through the center-positive barrel jack (J27). The 
external supply voltage must be 12 V ±5 %. The Genesys 2 cannot be powered from the USB bus. 

All Genesys 2 power supplies can be turned on and off together by a single logic-level power switch (SW8). Power supplies are 
either enabled/disabled directly by the power switch or indirectly by other supplies upstream. A power-good LED () (LD15), 
driven by the “power good” output of the on-board regulators, indicates that the supplies are turned on and operating 
normally. An overview of the Genesys 2 power circuit is shown in Figure 1.
