Introductory level demonstration project for Arty, designed using Vivado 2015.1.
- Arty FPGA board
- Micro-USB cable
- Vivado Design Suite 2016.4
- Newer versions can be used, but the procedure may vary slightly
- 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.
1. Generate the Project
1.1) Download the repository linked in the download section and place it in the location of your choosing.
1.2) Generate the GPIO project in the Projects folder by following this guide before continuing: How to Generate a Project from Digilent's Github
2. Build the Project
2.1) Click Generate Bitstream on the left hand menu towards the bottom. Vivado will run through both Run Synthesis and Run Implementation before it generates the bitstream automatically.
Note: If you want, you can click each step by itself in the order of Run Synthesis, Run Implementation and then Generate Bitstream.
3. Program the Board
3.2) Click program to load the project onto your Arty.
4. Run the Project
To run all the features of this demo, you will only need the Arty board.
4.2) UART Communication Using the Buttons
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). On startup, ARTY will transmit “ARTY GPIO/UART DEMO!”. Whenever a button is pressed, ARTY transmits “Button press detected!”.
