Rev. 0 | Page 7 of 20 EVAL-AD2S1210 EVALUATION BOARD SOFTWARE INSTALLING THE SOFTWARE SETTING UP THE EVAL-CED1Z The EVAL-AD2S1210 evaluation kit includes self-installing software on a CD-ROM for controlling and evaluating the performance of the AD2S1210 when it is operated with the EVAL-CED1Z. The software is compatible with Windows® 2000/XP®. If the setup file does not run automatically, setup.exe can be run from the CD-ROM. This section describes how the evaluation board, the EVALCED1Z, and the software should be set up to begin using the complete system. 1. 2. When the CD is inserted into the PC, an installation program automatically begins. This program installs the evaluation software. The user interface on the PC is a dedicated program written especially for the AD2S1210 when operating with the EVAL-CED1Z. Install the software before connecting the USB cable between the EVAL-CED1Z and the PC. This ensures that the appropriate USB driver files have been properly installed before the EVALCED1Z is connected to the PC. When the software is run for the first time with the EVAL-CED1Z connected to the PC, the PC automatically finds the new device and identifies it. Follow the onscreen instructions that appear automatically. This installs the drivers for the EVAL-CED1Z on the PC. If an error appears on screen when the software is first opened, then the PC is not recognizing the USB device. To correct this error, 1. Right-click the My Computer icon, then select Properties. When the System Properties window opens, select the Hardware tab. 2. Click Device Manager in the Hardware tab of the System Properties window. 3. Examine the devices listed under the Universal Serial Bus Controller heading. 4. If an unknown device is listed, right-click this option and select Update Driver. 5. The New Hardware Wizard runs twice, and under the ADI Development Tools, the hardware is listed as ADI Converter Evaluation and Development Board (WF). 6. Reboot your PC. 3. 4. 5. Install the AD2S1210 evaluation board software. Connect the EVAL-CED1Z and the evaluation board together via the 96-way connector. Apply power to the EVAL-CED1Z via the provided +7 V, 15 W power supply. At this stage, the green Power LED on the EVAL-CED1Z should light up, which indicates that the EVAL-CED1Z is receiving power The USB cable can then be connected between the PC and the EVAL-CED1Z. A green LED positioned beside the USB connector on the EVAL-CED1Z lights up indicating that the USB connection has been established. The EVAL-CED1Z is detected. Proceed through any dialog boxes that may appear (use the recommended options) to finalize the installation. Start the EVAL-AD2S1210 software. The FPGA code is automatically downloaded to the EVAL-CED1Z. The red LED, D14, on the EVAL-CED1Z now lights up. This indicates that the EVAL-CED1Z is functional and ready to receive instructions. The software can now be operated as described in the following sections. Note that when completing conversions on the AD2S1210 evaluation board while using the EVAL-CED1Z board, D14, the red LED on the EVAL-CED1Z, lights up to indicate that the USB transmission is occurring. Rev. 0 | Page 8 of 20 EVAL-AD2S1210 SOFTWARE OPERATION The data capture display section consists of the following subtabs: With the hardware set up, you can now use the software to control the EVAL-CED1Z and the AD2S1210 evaluation board. To launch the software, from the Analog Devices menu, select the AD2S1210 Evaluation Software submenu, and then AD2S1210 Ver0. Figure 3 displays the main window that is opened. If an error message appears, click Continue and restart the application after checking the connection between the adapter board and the USB port on the PC. Also check that the USB device is identified by the Device Manager as detailed in the Installing the Software section. • • • • • • The software that controls the EVAL-CED1Z and, therefore, the AD2S1210 evaluation board, has one main window. Figure 3 shows the window that appears when the software is run. The main function of this window is to allow you to read samples from the evaluation board and display them. The window can be divided into three main sections. Note that the AD2S1210 evaluation software has two modes of operation, normal mode and stream mode. In normal mode, the software is designed to gather a defined number of samples and display those results on the data capture display. In stream mode, the software is designed to continuously sample the AD2S1210 in defined measurement intervals, and display the results as a continuous stream of data on the data capture display. The Acquisition (Codes), Acquisition (Degrees/RPS), Histogram Position, and Histogram Velocity tabs operate in normal mode. The Stream (Codes) and Stream (Degrees/RPS) tabs operate in stream mode. These modes of operation are outlined in more detail in the Taking Samples section. 08036-003 The menu bar is located at the top of the window. The control buttons are below the menu bar, followed by a data capture display.

The CED Buffer indicator provides an indication of the available memory remaining. If there is increased activity on the USB port, the transfer of data may be slowed down, which may cause the external memory to fill before the data can be uploaded to the PC. In this case, the CED Buffer indicator shows that the buffer is full. You should either disconnect other external devices that may be using the USB port, or you can increase the conversion loop interval to decrease the number of samples to upload, which eases the requirement on the USB port. Note also that the transfer of data from the EVAL-CED1Z to the PC is slower when connected to a USB 1.1 port than when connected to a USB 2.0 port. Save as Picture. Saves the front panel as a JPEG file. Data Capture Display Exit. Exits the program. In the data capture display, you can select the format in which to view the position and velocity conversion results. The position data can be displayed in digital output code format or in degrees. The velocity data can be displayed in digital output code format or in rotations per second (RPS). The desired display options are selected by clicking on the Acquisition (Codes), Acquisition (Degrees/RPS), Stream (Codes), Stream (Degrees/RPS), Histogram Position, and Histogram Velocity tabs. USING THE SOFTWARE Menu Bar The menu bar consists of the File and Help submenus. File Menu Save Data (Acquisition).

Stream (Degrees/RPS) Tab The Stream (Degrees/RPS) tab displays the conversion results taken in stream mode of the position and velocity of the resolver connected to the AD2S1210 evaluation board. The position conversion result is displayed in degrees on the upper graph. The lower graph displays the velocity conversion results in RPS. At the bottom right of each graph are the zoom options. These allow you to zoom in and out to obtain a closer look at a sample if required. Histogram Position Tab The Histogram Position tab displays the histogram of the position conversion results taken in normal mode of the resolver connected to the AD2S1210 evaluation board. To enable this option, you must set the ON/OFF button to the on position. The histogram is displayed only when the output code varies for the one block of samples; that is, if the same conversion result is returned for all samples, the histogram is not displayed. At the bottom right of each graph are the zoom options. These allow you to zoom in and out to obtain a closer look at a sample if required. Histogram Velocity Tab The Histogram Velocity tab displays the histogram of the velocity conversion results taken in normal mode of the resolver connected to the AD2S1210 evaluation board. To enable this option, you must set the ON/OFF button to the on position. The histogram is displayed only when the output code varies for the one block of samples; that is, if the same conversion result is returned for all samples, the histogram is not displayed. At the bottom left of each graph are the zoom options. These allow you to zoom in and out to obtain a closer look at a sample if required. TAKING SAMPLES Initiating Conversions on the AD2S1210 Evaluation Board To initiate conversions and to capture the sample data, you must click the Single Acquisition, Reoccurring Acquisition, or Continuous Stream button. When the Single Acquisition or Reoccurring Acquisition button is clicked, the AD2S1210 evaluation software takes samples in normal mode. When the Continuous Stream button is clicked, the AD2S1210 evaluation software takes samples in stream mode. When the Single Acquisition button is clicked, the software instructs the EVAL-CED1Z to read back the conversion results from the AD2S1210 evaluation board. The number of samples is selected via the Num Samples box. After each conversion, data from the AD2S1210 is written to external memory on the EVAL-CED1Z. The required set of samples is uploaded through the USB port to the PC when the all conversions are completed. When you click the Reoccurring Acquisition button, the software instructs the EVAL-CED1Z to read back the conversion results from the AD2S1210 evaluation board in a repeating loop. The number of samples is selected via the Num Samples box. After each conversion, data from the AD2S1210 is written to external memory on the EVAL-CED1Z. The required set of samples is uploaded through the USB port to the PC when all the conversions are completed. If the Reoccurring Acquisition button is not clicked again to release the loop, the conversion loop repeats. While the data is being uploaded to the PC, the AD2S1210 device is not converting; therefore, there is a time delay between two blocks of samples. When the Continuous Stream button is clicked, the software instructs the EVAL-CED1Z to read back the conversion results from the AD2S1210 evaluation board. After each conversion, data from the AD2S1210 is written to external memory on the EVAL-CED1Z. At regular intervals, blocks of samples results are uploaded through the USB port to the PC. In Continuous Stream mode, while the data are uploaded to the PC, the AD2S1210 device is still converting. Therefore, there is no additional time delay between samples. In single acquisition, reoccurring acquisition, and continuous stream mode, the data is displayed on the data capture display. When the Single Acquisition or the Reoccurring Acquisition button is clicked, the data is displayed on the Acquisition (Codes), Acquisition (Degrees/RPS), Histogram Position, and Histogram Velocity tabs only. When the user clicks the Continuous Stream button, the data is displayed on the Stream (Codes) and Stream (Degrees/RPS) tabs only. Rev. 0 | Page 11 of 20 EVAL-AD2S1210 READING FROM AND WRITING TO REGISTERS ON THE AD2S1210 set by the Resolution : 10/12/14/16 bits drop-down box on the main window (see Figure 3). To read from and write to the registers on the AD2S1210, click the Registers button (see Figure 3). When you click the Registers button, the software instructs the EVAL-CED1Z to read the data in the AD2S1210 registers and displays this information in another window (see Figure 4). The register data is presented in decimal format. All registers are displayed on the right side of the window. Hysteresis. Enables or disables the hysteresis features of the AD2S1210. To change the settings of any displayed register other than the control register, you must overwrite the displayed decimal value by typing or selecting the new value, and then click the Send button. To overwrite the control register, use the four dropdown boxes on the left side of the window. Encoder Resolution. Selects the encoder resolution of the AD2S1210. Actual value sent to Control Register. Indicates the value that is written to the control register after clicking the Send button. Note that one or all of the registers can be written to with a single update. If you do not want to send any data to the registers, click the Cancel button. 08036-004 Resolution. Selects the software resolution of the RDC in the control register. This value must match the hardware resolution Phase Lock Range. Selects one of two phase lock ranges of the AD2S1210. Figure 4.
