Arty Z7 HDMI In Demo
Overview
Description
The Arty Z7 HDMI In project demonstrates the usage of the HDMI in and out ports on the Arty Z7 board. There are two projects, one for each variant of the board: Arty Z7-10 and Arty Z7-20. The behavior is as follows:
- Video data streams in through the HDMI in port and out through the HDMI out port.
- A UART interface is available to configure what is output through HDMI.
- There are 3 display frame buffers that the user can choose to display or write to.

Download and Launch the Arty Z7 HDMI Input Demo
1) Follow the Using Digilent Github Demo Projects Tutorial. Since this is a Vivado SDK Project, you can either directly launch SDK and import the hardware handoff, or you can generate a bitstream in Vivado before launching SDK. Select the hardware handoff options in the tutorial if you don't want to modify the project block design later. Return to this guide when prompted to check for additional hardware requirements and setup.
2) Plug one end of the HDMI cable into a video monitor and the other into the Arty Z7 HDMI out port. Do the same for an HDMI source, likely your computer, and the HDMI in port.
3) Turn on your board and open a serial terminal (such as TeraTerm) on your computer to receive status messages. Setup the serial port to connect to the appropriate port for your board, with a baud rate of 115200, 8 data bits, no parity bit and 1 stop bit. Then return to the Github Project Tutorial to finish programming and running the demo.
Using the Arty Z7 HDMI Input Demo
HDMI Display Options
1 - Change the resolution of the HDMI output to the monitor.
2 - Change the frame buffer to display on the HDMI monitor.
3/4 - Store a test pattern in the chosen video frame buffer - color bar or blended.
5 - Start/Stop streaming video data from HDMI to the chosen video frame buffer.
6 - Change the video frame buffer that HDMI data is streamed into.
7 - Invert and store the current video frame into the next video frame buffer and display it.
8 - Scale the current video frame to the display resolution, store it into the next video frame buffer, and then display it.
