 +===== 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. |
  
-  * 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. +Commands can be executed using a serial terminal connected to the UART peripheral of Xilinx KC705 FPGA.
-  * The **//DAC//** switch is used to enable/disable the input of the 74HCT244 octal buffer present on the evaluation board. When the switch is pressed the buffer’s input is enabled and it is possible to communicate with the DAC on SPI. +
-  * The **//LDAC//** switch is used to control the LDAC signal of the AD5541A. When the switch is pressed the DAC register is updated with the contents of the serial register data. +
-  * The **//DAC Value//** slider is used to set the value to be loaded into the DAC register. The selected value is displayed in the numeric box next to the slider.+
  
-===== Troubleshooting =====+The following image shows a generic list of commands in a serial terminal connected to Xilinx KC705 FPGA's UART peripheral.

-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.+
