-===== Demonstration Project User Interface ​===== +
- +
-The following figure presents the **uC-Probe** interface that can be used for monitoring and controlling the operation of the **EVAL-AD5272SDZ** evaluation board. +
- +
-{{ :​resources:​fpga:​altera:​bemicro:​ad5272interface.png?​700 }} +
- +
-**Section A** is used to activate the board and monitor activity. 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. +
- +
-**Section B** displays the data that is read from the RDAC register. +
- +
-**Section C** is used to write data to RDAC register. +
- +
-**Section D** allows access to the control register, enabling or disabling the resistor performance mode, RDAC write protection, and the 50-TP memory.+
  
-  * 50-TP Program – enables/​disables device for 50-TP program. +<WRAP round important 80%> 
-  * RDAC Write Protect – allows or not update ​of wiper position through a digital interface+\\ 
-  * Resistor Performance – enables/disables resistor tolerance calibration.+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>
  
-**Section E** is used to reset and to shutdown ​the device.+  ​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.
  
-  ​Soft Reset – sends a reset by software+===== Reference Project Overview ===== 
-  Hard Reset – sends a reset by hardware+The following commands were implemented in this version of EVAL-AD5272 reference project for Xilinx KC705 FPGA board. 
-  Power Down – powers down the part.+^ Command ^ Description ^ 
 +**help?** | Displays all available commands| 
 +**reset!**| Makes software ​reset of the device| 
 +**rdac=** | Writes to the RDAC register. Accepted values:\\ 0 .. 1024 (0 .. 255 for AD5274) - 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|
  
-**Section F** is used read/​write ​the 50-TP memory.+Commands can be executed using a serial terminal connected to the UART peripheral of Xilinx KC705 FPGA.
  
-  * Blow Fuse – blows the actual RDAC register data in the 50-TP memory+The following image shows a generic list of commands ​in a serial terminal connected to Xilinx KC705 FPGA's UART peripheral
-  * Read Fuse Content – reads content of 50-TP memory. +{{ :​resources:​fpga:​xilinx:​interposer:​Terminal_KC705.jpg? }}
-  * Read Fuse Address – reads address of the last 50-TP programmed memory location.+
  
-===== Troubleshooting ​=====+===== Software Project Setup ===== 
 +{{page>​import_workspace}}
  
-In case there is a communication problem with the board the follwing actions can be perfomed in order to try to fix the issues: 
-  * Check that the evaluation board is powered as instructed in the board'​s user guide. 
-  * 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.
