+===== Evaluation Boards =====
+  * [[adi>EVAL-AD5541ASDZ]]
+====== Overview ======
+This document presents the steps to setup an environment for using the **[[adi>AD5541A|EVAL-AD5541ASDZ]]** evaluation board together with the Xilinx KC705 FPGA board and the Xilinx Embedded Development Kit (EDK). Below is presented a picture of the EVAL-AD5541ASDZ Evaluation Board with the Xilinx KC705 board.

+The [[adi>AD5541A]] is a single, 16-bit, serial input, unbuffered voltage output digital-to-analog converter (DAC) that operates from a single 2.7 V to 5.5 V supply. The DAC output range extends from 0 V to VREF and is guaranteed monotonic, providing ±1 LSB INL accuracy at 16 bits without adjustment over the full specified temperature range of -40°C to +125°C. Offering unbuffered outputs, the AD5541A achieves a 1 µs settling time with low power consumption and low offset errors. Providing low noise performance of 11.8 nV/vHz and low glitch, the AD5541A is suitable for deployment across multiple end systems. The AD5541A uses a versatile 3-wire interface that is compatible with 50 MHz SPI, QSPI™, MICROWIRE™, and DSP interface standards.
+The **EVAL-AD5541ASDZ** evaluation board is designed to help customers quickly prototype new AD5541A circuits and reduce design time.

+====== Run the Demonstration Project ======
+===== Hardware setup =====
+<WRAP round important 80%>
+\\
+Before connecting the ADI evaluation board to the Xilinx KC705 make sure that the VADJ_FPGA voltage of the KC705 is set to 3.3V. For more details on how to change the setting for VADJ_FPGA visit the Xilinx KC705 product page.
+</WRAP>
+  * Use the FMC-SDP interposer to connect the ADI evaluation board to the Xilinx KC705 board on the FMC LPC connector.
+  * Connect the JTAG and UART cables to the KC705 and power up the FPGA board.
+===== Quick start evaluation =====
+For a quick start evaluation, run the **download.bat** script located in the **SDK/SDK_Workspace/bin** folder provided within the Reference Design Files.  This script uses XMD to program the FPGA with the HDL Reference Design and download the Software Reference Design into the DDR.
+<WRAP round info 80%>
+\\
+The **download.bat** script assumes that the Xilinx ISE Design Suite 14.6 is installed at this path: **C:/Xilinx/14.6**. If the installation path on your computer is different, please modify the script accordingly.
+</WRAP>
+If programming was successful, you should be seeing the command messages appear on the terminal.
+===== Reference Project Overview =====
+The following commands were implemented in this version of EVAL-AD5541A reference project for Xilinx KC705 FPGA board.
+^ Command ^ Description ^
+| **help?** | Displays all available commands. |
+| **voltage=** | Sets the DAC output voltage. Accepted values:\\ 0 .. 2500 - desired output voltage in milivolts. |
+| **voltage?** |  Displays last written voltage value to the DAC. |
+| **register=** | Writes to the DAC register. Accepted values:\\ 0 .. 65535 -  the value written to the DAC. |
+| **register?** | Displays last written value in the DAC register. |
+Commands can be executed using a serial terminal connected to the UART peripheral of Xilinx KC705 FPGA.
+The following image shows a generic list of commands in a serial terminal connected to Xilinx KC705 FPGA's UART peripheral.
