Arty S7 General I/O Demo

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

• Arty S7 with a MicroUSB Programming Cable
• Vivado installation compatible with the latest release of this demo (2020.1)
  • See Installing Vivado, Vitis, and Digilent Board Files for installation instructions.
• Serial Terminal application to receive messages printed by the demo
  • See Installing and Using a Terminal Emulator (Redirect) for more information.

First and foremost, releases - consisting of a set of files for download - are only compatible with a specific version of the Xilinx tools, as specified in the name of the release (referred to as a release tag). In addition, releases are only compatible with the specified variant of the board. For example, a release tagged “20/DMA/2020.1” for the Zybo Z7 is only to be used with the -20 variant of the board and Vivado 2020.1.

The latest release version for this demo is highlighted in green.

Note: Releases for FPGA demos from before 2020.1 used a different git structure, and used a different release tag naming scheme.

Note for Advanced Users: All demos for the Arty S7 are provided through the Arty-S7 repository on Github. Further documentation on the structure of this repository can be found on this wiki's Digilent FPGA Demo Git Repositories (Redirect) page.

Instructions on the use of the latest release can be found in this dropdown:

Set up the Arty S7

Plug the microUSB programming cable into the Arty S7's PROG/UART port

At this point, the demo is now running on your board. Refer to the Description and Functionality sections of this document for more information on what it does.

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!”.

All materials related to the use of the Arty S7 can be found on its Resource Center.

For a walkthrough of the process of creating a simple HDL project in Vivado, see Getting Started with Vivado for Hardware-Only Designs (Redirect). Information on important parts of the GUI, and indirect discussion of the steps required to modify, rebuild, and run this demo in hardware can also be found here.
