Arty Z7 HDMI Out Demo



The Arty Z7 HDMI Out project demonstrates the usage of the HDMI out port 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:

  • Frames stream out through the HDMI 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.

Download and Launch the Arty Z7 HDMI 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.

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.
