+ | ===== Description ===== | ||
+ | |||
+ | This project is a Vivado demo using the Nexys Video' | ||
+ | |||
+ | The selected channels and pins are as follows: | ||
+ | ^ XADC Channel | ||
+ | | AD1 | JXADC1(P) / JXADC7(N) | ||
+ | | AD0 | JXADC2(P) / JXADC8(N) | ||
+ | | AD8 | JXADC3(P) / JXADC9(N) | ||
+ | | AD9 | JXADC4(P) / JXADC10(N) | ||
+ | |||
+ | ---- | ||
+ | ===== Inventory ===== | ||
+ | |||
+ | * Nexys Video | ||
+ | * A MicroUSB Cable | ||
+ | * Vivado installation compatible with the latest release of this demo (2022.1) | ||
+ | * //See [[programmable-logic: | ||
+ | * Nexys Video 12 Volt Power Supply | ||
+ | * Wires and a circuit to measure | ||
+ | |||

+ | ===== 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 " | ||
+ | |||
+ | 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.// | ||

+ | --> Set up the Nexys Video # | ||
+ | |||
+ | Plug the 12V Power Supply into the Nexys Video. | ||
+ | |||
+ | Plug the MicroUSB into the PROG port. | ||
+ | |||
+ | The circuit and wires can be attached after the demo is already running. | ||

+ | ===== Functionality ===== | ||
+ | |||
+ | ====1. Applying a Voltage to the XADC Port==== | ||
+ | |||
+ | >For this demo, the AD1, AD0, AD8, and AD9 differential inputs on the JXADC header are used. We constructed a resistor ladder to connect each of the four channels' | ||
+ | > | ||
+ | > | ||
+ | |||
+ | |||
+ | ====2. OLED Display==== | ||
+ | |||
+ | >The OLED display shows the Voltage differential across each of the xadc pin pairs located on JXADC. | ||
+ | > | ||
+ | > | ||
+ | |||

+ | ===Important=== | ||
+ | Before turning off or reprogramming your board, shut down the OLED display by pressing the **CPU_RESET** button. | ||
