====== Cora Z7 Basic I/O Demo ====== {{:reference:programmable-logic:cora-z7:demos:cora2.jpg?400|}} ---- ===== Description ===== This project is a Vivado demo using the Cora Z7's RGB LED's and pushbuttons, written in Verilog. * When programmed onto the board, the RGB LEDs will cycle from Blue to Green to Red to off * As long as one of the two buttons is pushed, the corresponding RGB LED will be turned off ---- ===== Inventory ===== * Cora Z7 with a MicroUSB Programming Cable * Vivado installation compatible with the latest release of this demo (2020.1) * //See [[programmable-logic:guides:installing-vivado-and-vitis|Installing Vivado, Vitis, and Digilent Board Files]] for installation instructions.// ---- ===== Download and Usage Instructions ===== First and foremost, releases - consisting of a set of files for download - are only compatible with a specific version of the Xilinx tools, as specified in the name of the release (referred to as a //release tag//). In addition, releases are only compatible with the specified variant of the board. For example, a release tagged "20/DMA/2020.1" for the Zybo Z7 is only to be used with the -20 variant of the board and Vivado 2020.1. The latest release version for this demo is highlighted in green. **Note:** //Releases for FPGA demos from before 2020.1 used a different git structure, and used a different release tag naming scheme.// ^ Board Variant ^ Release Tag ^ Release Downloads ^ Setup Instructions ^ | Cora Z7-07S | @#C0EEBD: 07S/Basic-IO/2022.1-1 | {{https://github.com/Digilent/Cora-Z7/releases/download/07S/Basic-IO/2022.1-1/Cora-Z7-07S-Basic-IO-hw.xpr.zip}} | See //Using the Latest Release//, below | | Cora Z7-10 | @#C0EEBD: 10/Basic-IO/2022.1-1 | {{https://github.com/Digilent/Cora-Z7/releases/download/10/Basic-IO/2022.1-1/Cora-Z7-10-Basic-IO-hw.xpr.zip}} | See //Using the Latest Release//, below | | Cora Z7-07S | 07S/Basic-IO/2021.1-1 | {{https://github.com/Digilent/Cora-Z7/releases/download/07S/Basic-IO/2021.1-1/Cora-Z7-07S-Basic-IO-hw.xpr.zip}} | See //Using the Latest Release//, below | | Cora Z7-10 | 10/Basic-IO/2021.1-1 | {{https://github.com/Digilent/Cora-Z7/releases/download/10/Basic-IO/2021.1-1/Cora-Z7-10-Basic-IO-hw.xpr.zip}} | See //Using the Latest Release//, below | | Cora Z7-07S | 07S/Basic-IO/2020.1-1 | {{https://github.com/Digilent/Cora-Z7/releases/download/07S/Basic-IO/2020.1-1/Cora-Z7-07S-Basic-IO-hw.xpr.zip}} | See //Using the Latest Release//, below | | Cora Z7-10 | 10/Basic-IO/2020.1-1 | {{https://github.com/Digilent/Cora-Z7/releases/download/10/Basic-IO/2020.1-1/Cora-Z7-10-Basic-IO-hw.xpr.zip}} | See //Using the Latest Release//, below | | Cora Z7-07S | v2018.2-1 | [[https://github.com/Digilent/Cora-Z7-07S-Basic-IO/releases/tag/v2018.2-1|Release ZIP downloads]] | [[https://github.com/Digilent/Cora-Z7-07S-Basic-IO/tree/v2018.2-1| v2018.2-1 Github README]] | | Cora Z7-10 | v2018.2-1 | [[https://github.com/Digilent/Cora-Z7-10-Basic-IO/releases/tag/v2018.2-1|Release ZIP downloads]] | [[https://github.com/Digilent/Cora-Z7-10-Basic-IO/tree/v2018.2-1| v2018.2-1 Github README]] | | Cora Z7-07S | 2017.4-1 | [[https://github.com/Digilent/Cora-Z7-07S-Basic-IO/releases/tag/2017.4-1|Release ZIP downloads]] | [[https://github.com/Digilent/Cora-Z7-07S-Basic-IO/tree/2017.4-1| 2017.4-1 Github README]] | | Cora Z7-10 | 2017.4-1 | [[https://github.com/Digilent/Cora-Z7-10-Basic-IO/releases/tag/2017.4-1|Release ZIP downloads]] | [[https://github.com/Digilent/Cora-Z7-10-Basic-IO/tree/2017.4-1| 2017.4-1 Github README]] | **Note for Advanced Users:** //GitHub sources for this demo can be found in the [[https://github.com/digilent/cora-z7/tree/07S/Basic-IO/master|07S/Basic-IO/master]] and [[https://github.com/digilent/cora-z7/tree/10/Basic-IO/master|10/Basic-IO/master]] branches of the Cora-Z7 repository.
