Download and Launch the Zedboard OLED Demo
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. Return to this guide when prompted to check for extra hardware requirements and setup.
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 JTAG port. Then return to the Github Projects Tutorial to finish programming the demo onto your board.
Using the Zedboard OLED Demo
1. Startup and Bringdown
The OLED display can be turned on and off by pressing the right D-Pad Button (BTNR). When the board is first programmed, the display will automatically be initialized. When you are done operating the demo, and want to turn your board off, press the CPU Reset Button to turn the display off. The status of the display is indicated by LED0, if it is on, the display is on. The display can be turned on from an off state by pressing the CPU Reset Button again.
Make sure to turn off the OLED display before shutting down or reprogramming your board.
