EVALUATION BOARD HARDWARE DEVICE DESCRIPTION This user guide describes the evaluation board for the AD2S1200 and the AD2S1205, which are 12-bit resolution tracking resolver-to-digital converters.

The AD2S1200 and the AD2S1205 integrate an on-chip programmable sinusoidal oscillator that provides sine wave excitation for resolvers.

The 12-bit angular position and velocity data is accessed via either a 12-bit parallel port or a 3-wire serial interface. On-chip incremental encoder emulation with direction output is also available for positional data.

On-chip fault detection detects loss of resolver signals, out of range input signals, input signal mismatch, and loss of position tracking.

Complete specifications for the AD2S1200 and the AD2S1205 are provided in the AD2S1200 and the AD2S1205 data sheets, available from Analog Devices, which should be consulted in conjunction with this user guide when using the evaluation board. Full details on the EVAL-SDP-CB1Z are available on the Analog Devices website.

HARDWARE LINK OPTIONS The function of the link options are described in Table 2. The default setup is configured to operate the board with the mains power supply adapter and to interface to the EVAL-SDP-CB1Z board via the parallel interface.

It is also possible to operate the board in standalone mode when interfacing to a user defined system. The evaluation board can be configured to operate in standalone serial or parallel mode by setting the necessary link options. Angular positional data can also be determined by interfacing with the encoder outputs.

POWER SUPPLIES Care should be taken before applying power and signals to the evaluation board to ensure that all link positions are as per the required operating mode. See Table 2 for the complete list of link options.

This evaluation board comes with a wall-mountable switching power supply that provides a 9 V dc output. Connect the supply to a 100 V to 240 V ac wall outlet at 50 Hz to 60 Hz. The output from the supply is provided through a 2.0 mm inner diameter jack that connects to the evaluation board at J702. The 9 V supply is connected to the various on-board power manage-ment devices that supply the correct bias to each of the various sections on the board and the EVAL-SDP-CB1Z board.

When using this evaluation board with the EVAL-SDP-CB1Z board, it is necessary to power the board through the J702 connector. The VCCY for the ADG3304 and ADG3308 level translator devices are sourced from the EVAL-SDP-CB1Z board.

In standalone configuration, it is possible to power the evaluation board through external power supplies via the relevant screw terminal connectors.

If the evaluation board is used without the 9 V adapter, 5 V must be connected to the AVDD input to supply the AD2S1200/ AD2S1205 AVDD pin. In addition, 5 V must be connected to the DVDD input to supply the AD2S1200/AD2S1205 DVDD pin. 12 V must be connected to the +12 V connector to supply the excitation buffer circuitry.

Each supply is decoupled on this board using 10 µF tantalum and 10 nF multilayer ceramic capacitors.

Extensive ground planes are used on this board to minimize the effect of high frequency noise interference. There are two main ground planes, AGND and DGND. These are connected at one location close to the AD2S1200/AD2S1205.

Data Capture Display

In the data capture display, you can select the format in which to view the position and velocity conversion results. The posi-tion 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), Histogram Position, and Histogram Velocity tabs.

Acquisition (Codes) Tab

The Acquisition (Codes) tab displays the conversion results taken in normal mode of the position and velocity of the resolver connected to the EVAL-AD2S1200/05SDZ board. The number of conversions results displayed is defined by the Number of Samples box. The conversion results are displayed as wave-forms in digital code on two graphs. The upper graph displays the position conversion results. The lower graph displays the velocity conversion results. The maximum, minimum, and mean values of the sample set are displayed on indicators to the right of each graph.

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.

Acquisition (Degrees/RPS) Tab

The Acquisition (Degrees/RPS) tab displays the conversion results taken in normal mode of the position and velocity of the resolver connected to the EVAL-AD2S1200/05SDZ board. The number of conversions results displayed is defined by the Number of Samples box. The position conversion result is displayed in degrees on the upper graph. The lower graph displays the velocity conversion results in RPS. The maximum, minimum, and mean values of the sample set are displayed on indicators to the right of each graph.


Histogram Position Tab

The Histogram Position tab displays the histogram of the posi-tion conversion results taken in normal mode of the resolver connected to the EVAL-AD2S1200/05SDZ 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.


Histogram Velocity Tab

The Histogram Velocity tab displays the histogram of the velocity conversion results taken in normal mode of the resolver con-nected to the EVAL-AD2S1200/05SDZ 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.

Within any of the chart panels, the tools shown in Figure 15 allow user control of the different chart displays.

Figure 15. Chart Tools

DATA CAPTURE To initiate conversions and to capture the sample data, you must click the Single Acquisition or the Reoccurring Acquisition button.

When the Single Acquisition button is clicked, the software instructs the EVAL-SDP-CB1Z to read back the conversion results from the EVAL-AD2S1200/05SDZ board. The number of samples is selected via the Number of Samples box. After each conversion, data from the AD2S120x is written to external memory on the EVAL-SDP-CB1Z. The required set of samples is uploaded through the USB port to the PC when all conver-sions are completed.

When you click the Reoccurring Acquisition button, the software instructs the EVAL-SDP-CB1Z to read back the conversion results from the EVAL-AD2S1200/05SDZ board in a repeating loop. The number of samples is selected via the Number of Samples box. After each conversion, data from the AD2S120x is written to external memory on the EVAL-SDP-CB1Z. 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 AD2S120x device is not converting; therefore, there may be a time delay between two blocks of samples.

In single acquisition and reoccurring acquisition mode, the data is displayed on the data capture display. The data is displayed on the Acquisition (Codes), Acquisition (Degrees/RPS), Histogram Position, and Histogram Velocity tabs.

Figure 16 shows a typical data capture. Both position and velocity data results are presented in the data capture display. Additionally, the following data is displayed:

• A summary of the measured positional data • A summary of the measured velocity data
