This document presents the steps to setup an environment for using the EVAL-AD5543SDZ evaluation board together with the Xilinx KC705 FPGA board, the Xilinx Embedded Development Kit (EDK) and the Micrium µC-Probe run-time monitoring tool. Below is presented a picture of the EVAL-AD5543SDZ Evaluation Board with the Xilinx KC705 board.
For component evaluation and performance purposes, as opposed to quick prototyping, the user is directed to use the part evaluation setup. This consists of:
The SDP-B controller board is part of Analog Devices System Demonstration Platform (SDP). It provides a high speed USB 2.0 connection from the PC to the component evaluation board. The PC runs the evaluation software. Each evaluation board, which is an SDP compatible daughter board, includes the necessary installation file required for performance testing.
Note: it is expected that the analog performance on the two platforms may differ.
Below is presented a picture of SDP-B Controller Board with the EVAL-AD5543SDZ Evaluation Board.
The EVAL-AD5543SDZ evaluation board is designed to help customers quickly prototype new AD5553 circuits and reduce design time.
The AD5553 is a precision, 14-bit, low power, current output, small form factor, digital-to-analog converter (DAC). It is designed to operate from a single 5 V supply with a ±10 V multiplying reference. The applied external reference, VREF, determines the full-scale output current. An internal feedback resistor (RFB) facilitates the R-2R and temperature tracking for voltage conversion when combined with an external op amp. A serial data interface offers high speed, 3-wire, microcontroller-compatible inputs using serial data input (SDI), clock (CLK), and chip select (CS).
The first objective is to ensure that you have all of the items needed and to install the software tools so that you are ready to create and run the evaluation project.
The following table presents a short description the reference design archive contents.
|Bit||Contains the KC705 configuration file that can be used to program the system for quick evaluation.|
|Microblaze||Contains the EDK 13.4 project for the Microblaze softcore that will be implemented in the KC705 FPGA.|
|Software||Contains the source files of the software project that will be run by the Microblaze processor.|
|uCProbeInterface||Contains the uCProbe interface and the .elf symbols file used by uC-Probe to access data from the Microblaze memory.|
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.
At this point everything is set up and it is possible to start the evaluation of the ADI hardware through the controls in the uC-Probe application provided in the reference design.
Launch uC-Probe from the Start → All Programs → Micrium → uC-Probe.
Select uC-Probe options.
Set target board communication protocol as RS-232
Setup RS-232 communication settings
The following figure presents the uC-Probe interface that can be used for monitoring and controlling the operation of the EVAL-AD5543SDZ evaluation board.
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 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. While the communication with the board is activated the value will be sent to the DAC via SPI continuously.
The Output Voltage numeric box will display the corresponding output voltage for the selected DAC value that can be measured on the VOUT connector.
In case there is a communication problem with the board the follwing actions can be perfomed in order to try to fix the issues:
