-===== Description ===== 
- 
-The OLED Demo project demonstrates a simple usage of the Nexys Video's  
-OLED Display. The behavior is as follows: 
-  
- * The user presses the CPU reset button to initialize the OLED display, this runs through the sequence to safely start the display. The user can then load a splash screen onto the display by pressing the DPad up button, clear the display by pressing the DPad down button. By pressing the DPad center button, the user can switch between the normal operating mode and a mode where each pixel on the display is on. To safely turn the display off again, the user can press the CPU reset button again.

-===== How to... ===== 
  
 +===== Download and Launch the Nexys Video OLED Demo =====
  
 +>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 extra hardware requirements and setup.
  
-==== 1. Generate the Project ====+>2) Ensure that your board is plugged into a 12 Volt power supply and connected to your computer via a Micro USB cable attached to the PROG port. Then return to the Github Projects Tutorial to finish programming the demo onto your board.
  
->1.1) Download the repository linked in the download section and place it in the location of your choosing.  +===== Using the Nexys Video OLED Demo ====
- +
->1.2) Generate the **Oled** project within the "Projects" folder by following this guide before continuing: [[vivado:github|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 ==== +
- +
->3.1) Once you have generated your bit file, Click on the hardware manager and connect to your board by choosing the local server option. +

 >The procedures for safely turning on and off the OLED display are handled by the CPU Reset Button. When the board is first turned on, the display is off, and must be brought up, press the CPU Reset Button to turn it on. Once the display is on, when you are done operating the demo, and want to turn your board off, press the CPU Reset Button again to turn the display off. The status of the display is indicated by LED0, if it is on, the display is on. >The procedures for safely turning on and off the OLED display are handled by the CPU Reset Button.
