The ZYBO HDMI project demonstrates the usage of the HDMI and VGA ports on the ZYBO. The behavior is as follows:
- Video data streams in through the HDMI port and out through the VGA port.
- A UART interface is available to configure what is output through VGA.
- There are 3 display frame buffers that the user can choose to display or write to.
- Basic familiarity with Vivado & SDK
- This experience can be found by walking through our “Getting Started with Vivado” guide
- ZYBO board
- Micro-USB cable
- HDMI cable
- HDMI source
- VGA monitor
- Vivado Design Suite & Xilinx SDK 2015.4
- Version 2015.4 must be used to generate the project
1. Generate the Project
1.1) Download the project linked in the download section and unzip it in the location of your choosing.
1.2) Generate the hdmi_in 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. Export to SDK
4. Import the SDK files
5. Program the FPGA
6. Program the Microblaze Processor
6.1) Click on the videodemo folder and click the Green Run System Debugger on Local videodemo.elf button. The microblaze program will be programmed onto your Zybo board.
7. Run the Project
This portion will help you run the demo and observe all its features.
7.3) HDMI display options
1 - Changes the resolution of the VGA output to the monitor.
2 - Changes the frame buffer to display on the VGA monitor.
3/4 - Stores a test pattern in the chosen Video Frame buffer.
5 - Starts/Stops streaming video data from HDMI to the chosen video frame buffer.
6 - Changes the video buffer that HDMI data is streamed into.
7 - Inverts and stores the current video frame into the next video frame buffer and displays it.
8 - Scales the current video frame to the display resolution and stores it into the next video frame buffer, then displays it.
