-===== How to...  ===== 
  
-==== 1. Generate the Project ====+===== Download and Launch the Arty Pmod VGA Demo =====
  
->1.1) Download the zip archive linked in the downloads section and place it in the location of your choosing.+>1) Follow the [[:learn:programmable-logic:tutorials:github-demos:start|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 additional hardware requirements and setup.
  
->1.2) Extract the project source from the downloaded archive.+>2) Once you have generated your bit file, make sure that you have your Pmod VGA plugged into your Arty's Pmod ports JB and JC. Use a VGA cable to connect the Pmod VGA to your monitor's VGA port. Return to the Github Projects Tutorial to finish programming your board.
  
->1.3) Generate the **PmodVGA** project by following this guide before continuing: [[vivado:github|How to Generate a Project from Digilent's Github]]+===== Using the Arty Pmod VGA Demo =====
  
-==== 2. Build the Project ====+==== 1. View Results ====
  
->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 ==== 
- 
->3.1) Once you have generated your bit file, Click on ** Open Hardware Manager** then connect to your board by choosing the local server option. 
->

- 
->3.2) Click **Program device** to load the project onto your Arty. 
- 
-==== 4. Run the Project ==== 
- 
-This portion will help you run the demo and observe all its features. 
- 
->4.1) Set up hardware 
-> 
->Connect the Pmod VGA to Pmod ports JB and JC. Connect the Pmod VGA's VGA port to the VGA port on your monitor. 
- 
->4.2) View results

->To select a different display resolution, select the appropriate set of Sync Generation constants for your target resolution from the list starting at line 47 of **top.vhd**. Uncomment the ten corresponding constants, FRAME_WIDTH through V_POL, and comment out the default versions of those same constants. The default resolution is 1920x1080 @ 60Hz.+>To select a different display resolution, select the appropriate set of Sync Generation constants for your target resolution from the list starting at line 47 of **top.vhd**.
