+Commands can be executed using a serial terminal connected to the UART peripheral of Xilinx KC705 FPGA.
-===== Demonstration Project User Interface =====
+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? }}
-This section presents the UART Terminal Interface, which helps the user to interact with the software application, that will run on the **Xilinx KC705** FPGA board.
+===== Software Project Setup =====
+{{page>import_workspace}}
-To use this interface, a terminal emulator software is needed, in this case the **Tera Term** is used.
-After programing the **KC705** FPGA with the //download.bit// file provided in the reference design archive, the message **AD5755 OK** should appear at the terminal window.
-{{ :resources:fpga:xilinx:interposer:adconnected.png?400 }}
-By using the command **help?**, can list out all the available commands for the current device, with a small description containing indications how to use them.
-{{ :resources:fpga:xilinx:interposer:terminal_help.png?400 }}
-The **AD5755** support the following commands, which can used to evaluate the converter:
-^ **Command** ^ **Description** ^
-| **help?** | Display all available commands |
-| **register?** | Get register value for a specified channel, the command has two arguments: register address and channel |
-| **register=** | Set a register value, the command has four arguments: register type, which can be data or control, register address, channel number and the desired value |
-| **power?** | Display the power state of the dc-to-dc converters, DAC and internal amplifiers for the selected channel. The command has one argument : channel |
