->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.+>Follow the [[learn:programmable-logic:tutorials:github-demos:start:|Using Digilent Github Demo Projects]] Tutorial.

->Plug one end of the HDMI cable into the HDMI TX port of the Zybo Z7 and the other into your HDMI monitor. Also attach a USB micro cable between the Zybo Z7 and your computer. Finally, attach an external 5V power supply if you don't want to power from USB. +>Plug one end of the HDMI cable into the HDMI TX port of the Zybo Z7 and the other into your HDMI monitor.

->Attach the Pcam 5C assembly (which includes the Pcam 5C and the attached 15-pin flat flexible cable) by inserting the other end of the FFC into the Pcam connector on the Zybo Z7 as shown in image below. Ensure the cable is securely latched by pressing down firmly on the connector with two fingers. For a more detailed set of instructions, see the Pcam section in the [[reference:programmable-logic:zybo-z7:reference-manual#pcam_port|Zybo Z7 Reference Manual]]. If the cable has become disconnected from the Pcam 5C, please see the [[:reference:add-ons:pcam-5c:reference-manual|Pcam 5C reference manual]] for instructions on how to reattach it.+>Attach the Pcam 5C assembly (which includes the Pcam 5C and the attached 15-pin flat flexible cable) by inserting the other end of the FFC into the Pcam connector on the Zybo Z7 as shown in image below.

 This demo uses our own software to configure the OV5640 image sensor and open source IP to post process the image data. Both of these facets of the software greatly affect image quality. This section documents the current quality of the images our software is able to produce with the Pcam 5C. We are aware that the quality of the image affects whether the Pcam 5C is suitable for some applications, so the information provided here can be used to help determine if the product will fit your needs. This demo uses our own software to configure the OV5640 image sensor and open source IP to post process the image data.

-We hope to improve the quality of the images produced by this demo over time, so please check back often if you are interested. We are also looking into using Xilinx IP and the Omnivision provided Linux drivers to provide another software option for the use of the Pcam 5C. This will be made available if successful on the [[:reference:add-ons:pcam-5c:start|Pcam 5C Resource Center]].+We hope to improve the quality of the images produced by this demo over time, so please check back often if you are interested.

->The top and left edges of the image have a single pixel gray line. This artifact is introduced by our post processing IP. It is a known issue we plan to resolve in a future release of our IP. The image below is taken with the Pcam 5C lens cap on, which makes the gray line very visible on the all black image. +>The top and left edges of the image have a single pixel gray line. This artifact is introduced by our post processing IP,  axis_raw_demosaic.
