-===== Demonstration Project User Interface =====+  * 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.
  
-The following ​figure presents ​the **uC-Probe** interface that can be used for monitoring and controlling ​the operation ​of the **EVAL-AD5270SDZ** evaluation board.+===== Reference Project Overview ===== 
 +The following ​commands were implemented in this version of EVAL-AD5270 reference project for Xilinx KC705 FPGA board. 
 +^ Command ^ Description ^ 
 +| **help?** | Displays all available commands. | 
 +| **reset!**| Makes a software reset of the device. | 
 +**rdac=** | Writes to the RDAC register. Accepted values:\\ 0 .. 1024 (0 .. 255 for AD5271) - the value written to RDAC. | 
 +| **rdac?** | Displays the last written value in RDAC register. | 
 +| **store!** | Stores the RDAC setting to 50-TP. | 
 +| **50TPValue?​** | Displays ​the contents ​of the selected 50-TP register. Accepted values:\\ 0 .. 50 - selected 50-TP register. | 
 +**50TPAddress?​** | Displays the address of the last programmed 50-TP register. | 
 +**power=** | Turns on/off the device. Accepted values:\\ 1 - normal mode.(default)\\ 0 - shutdown mode. | 
 +| **power?** | Displays the power status of the device|

-The communication with the board is activated / deactivated by toggling the **//​ON/​OFF//​** switch. The **//​Activity//​** LED turns green when the communication is active. If the **//​ON/​OFF//​** switch is set to **//ON//** and the **//​Activity//​** LED is **//​BLACK//​** it means that there is a communication problem with the board. See the **Troubleshooting** section for indications on how to fix the communication problems. 
  
-The rheostat value is set by the //​**"​Rheostat Value"​**//​ slider.+Commands can be executed using a serial terminal connected to the UART peripheral of Xilinx KC705 FPGA.
  
-===== Troubleshooting =====+The following image shows a generic list of commands in a serial terminal connected to Xilinx KC705 FPGA's UART peripheral. 
 +{{ :​resources:​fpga:​xilinx:​interposer:​Terminal_KC705.jpg?​ }}
  
-In case there is a communication problem with the board the follwing actions can be perfomed in order to try to fix the issues: +===== Software Project Setup ===== 
-  * Check that the evaluation board is powered as instructed in the board'​s user guide. +{{page>​import_workspace}}
-  * In uC-Probe refresh the symbols file by right-clicking on the **//System Browser//** window and selecting **//Refresh Symbols//​**. +
-  * If the communication problem persists even after performing the previous steps, restart the uC-Probe application and try to run the interface again.+
