 ------- -------
-===== How to..=====+===== Download and Launch the Arty Z7 HDMI Input Demo =====
  
-==== 1. Generate the Project ====+>1) Follow the [[:learn:programmable-logic:tutorials:github-demos:start:|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.
  
->1.1) Download the project linked in the download section and unzip it in the location of your choosing.  +>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.
- +
->1.2) Generate the **hdmi_in** project in 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**. +>{{:learn:programmable-logic:tutorials:arty-z7:hdmi_in_setup.jpg?500|}}
-> +
->{{:basys3:buildflow.png?600|}} +
-==== 3. Export to SDK ====+
  
->3.1) Export the microblaze project by going to **File>Export>Export Hardware**. Click the check box to **Include the bitstream**, and export it local to project. This will create a .sdk folder in your project directory. Afterwards, click **File>Launch SDK** to launch Xilinx SDK.+>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.

-==== 4. Import the SDK files ====+
  
->4.1) In your project Explorer window on the left side, click **File>Import** then expand the General tab and click **Existing Projects into Workspace**. Navigate to the Projects/hdmi_out folder, select the **sdk** folder, and click OK. In the //Import// window, click Finish to import the SDK project.

-==== 5. Program the FPGA ==== 
  
->5.1) Click **Xilinx Tools>Program FPGA** and click **Program**. Xilinx SDK will then program the FPGA with a microblaze bit file. +===== Using the Arty Z7 HDMI Input Demo =====

-==== 6. Program the Microblaze Processor ====+==== HDMI Display Options ====
  
->6.1) Click on the **hdmi_in** folder and click the Green **Run System Debugger on Local videodemo.elf** button. The microblaze program will be programmed onto your Arty Z7 board. +>  1 - Change the resolution of the HDMI output to the monitor.

-This portion will help you run the demo and observe all its features.+>  2 - Change the frame buffer to display on the HDMI monitor.
  
->7.1) Setup+>  3/4 - Store a test pattern in the chosen video frame buffer - color bar or blended.
 > >
->Plug one end of the HDMI cable into a video source and the other into the ZYBO HDMI port. Plug one end of your other HDMI cable into the HDMI Out port of the Arty Z7 and the other into your HDMI monitor. +>{{:learn:programmable-logic:tutorials:arty-z7:hdmi_incolorbar.jpg?500|}}{{:learn:programmable-logic:tutorials:arty-z7:hdmi_inblend.jpg?500|}}

->7.2) Setting up UART communications +>  5 - Start/Stop streaming video data from HDMI to the chosen video frame buffer.
-> +
->To see the UART communication channel, open a terminal program on your computer set to 112500 baud rate, 8 data bits, no parity bit and 1 stop bit. On startup, the Arty Z7 will display the HDMI settings menu, shown below. +
