1) Follow the Using Digilent Github Demo Projects Tutorial. This is an HDL design project, and as such does not support Vivado SDK, select the tutorial options appropriate for a Vivado-only design. Return to this guide when prompted to check for extra hardware requirements and setup.
2) In order to fully use the demo, you will need to connect a serial terminal to your Nexys Video. Plug your board into your computer with Micro USB cables attached to the PROG and UART ports and make sure the board is turned on. Then open a serial terminal (such as TeraTerm) on your computer. In the terminal application, setup the serial port to connect to the appropriate port for your board, with a baud rate of 9600. Then return to the Github Projects Tutorial to finish programming and running the demo.
On startup, the Nexys Video will transmit “Nexys Video GPIO/UART DEMO!”. Whenever one of BTNU, BTNL, BTND, or BTNR is pressed, the Nexys Video transmits “Button press detected!”.
Before turning off or reprogramming your board, shut down the OLED display by pressing the CPU_RESET button.
