Arty S7 General I/O Demo

Introductory level demonstration project for the Arty S7's LEDs, switches, buttons, and USB-UART bridge.

• Arty S7 FPGA board
• Micro-USB cable

• Vivado Design Suite 2017.2
  • Newer versions can be used, but the procedure may vary slightly
  • Currently you need to use the Design Edition for the Spartan 7 do to an error with the Spartan 7 in the Webpack edition
  • The Design Edition of Vivado will work without a Design Edition license as long as you are not targeting a device that requires the Design Edition license.
• Digilent Board Support Files for Vivado
  • Follow the Vivado Board Files for Digilent 7-Series FPGA Boards guide on how to install Board Support Files for Vivado.

Arty S7 GPIO Project Support Repository – ZIP Archive GIT Repo

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. When prompted to return…

2.) To see the UART communication channel, open a terminal program on your computer set to 9600 baud, 8 data bits, no parity bit and 1 stop bit. Choose the COM port that your ARTY is connected to (To determine what COM port your Arty is connected to, open up Device Manager on your machine. Under Ports (COM & LPT) you should see something like 'USB Serial Port (COMX)' where the X is the number of the connected COM port). Then return to the Github Project Tutorial to finish programming and running the demo.

To run all the features of this demo, you will only need the Arty S7 board.

For this section, all the switches are tied to their corresponding led. Every time a switch is toggled, the led directly above it will toggle with it.

The two tri-color LEDs will cycle colors with no interruption from other I/O.

On startup, the Arty S7 will transmit “ARTY GPIO/UART DEMO!”. Whenever a button is pressed, Arty S7 transmits “Button press detected!”.
