ADIS16265 EVALUATION ON THE EVAL-ADIS
OVERVIEW
The ADIS16265 is a fully calibrated, digital gyroscope provides +/-320 degrees/second of measurement range. The standard supply voltage (+5V) and serial peripheral interface (SPI) enable simple integration into most industrial system designs. A simple internal register structure handles all output data and configuration features. This includes access to the following output data: calibrated rotation rate, power supply, internal temperature, auxiliary analog and digital input signals, diagnostic error flags, and programmable alarm conditions.
The electrical connection typically only requires 5 I/O lines for synchronous data collection, as shown in the following figure:
ADIS16265/PCB BREAKOUT BOARD
For those who are on a tight timeline, connecting the ADIS16265 to an embedded controller will provide the most flexibility in developing application firmware and will more closely reflect the final system design. The ADIS16265/PCBZ is the breakout board for the ADIS16265 and may provide assistance in the process of hooking it up to an existing embedded processor system.
EQUIPMENT LIST
SYSTEM REQUIREMENTS
Windows XP, Vista, 7
.NET Framework 3.5
NOTE: Newer versions of the .NET framework do not currently support the IMU Evaluation software package.
PHYSICAL SETUP
The ADIS16265 provides the EVAL-ADIS16265 function on a 1.2 inch × 1.3 inch printed circuit board (PCB), which simplifies the connection to an existing processor system. The four mounting holes accommodate either M2 (2mm) or Type 2-56 machine screws. These boards are made of IS410 material and are 0.063 inches thick. The second level assembly uses a SAC305-compatible solder composition (Pb-free), which has a pre-solder re-flow thickness of approximately 0.005 inches. The pad pattern on the ADIS16265/PCBZ matches that shown in below. J1 and J2 are dual-row, 2 mm (pitch) connectors that work with a number of ribbon cable systems, including 3M Part Number 152212-0100-GB (ribbon-crimp connector) and 3M Part Number 3625/12 (ribbon cable).
NOTE: Do not plug the EVAL-ADIS into the USB cable at this stage of the setup. Wait until the software installation is complete.
Step #1
The connection to the ADIS16265/PCBZ is simple using J1 and a 16 pin cable included with the EVAL-ADIS.
WARNING: Make sure that the connector cable going from J1 on the ADIS16265/PCBZ is properly aligned to the J1 connector on the EVAL-ADIS. The 16 pin cable is included with the EVAL-ADIS and proper mating has the last 4 cable connections open. The Black wire from from J2-12 of the ADIS16265/PCBZ to the DIO1 test point on the EVAL-ADIS is only required for synchronous data.
Step #2
Mounting to the system frame is accomplished using 4 M2x.4x4mm machine screws included with the ADIS16265/PCBZ. The mounting location holes are marked as an example in the picture below. Use the 4 A-location holes to secure the ADIS16265/PCBZ to the EVAL-ADIS.
Step #3
The following picture (left side) shows JP1 in the +3.3V position (factory-default). That is not the correct JP1 jumper setting on the EVAL-ADIS) required for the ADIS16265CCCZand should be moved to the *+5V* position (right side).
NOTE: If JP1 is left on +3.3v position the software will look like the following picture. Move JP1 to the+5V setting to correct the problem.
IMU EVALUATION SOFTWARE DOWNLOAD/GETTING STARTED
Visit the IMU Evaluation Software Wiki Guide for software download, driver installation and basic, “getting started” instructions.
QUICK TIP: Right click on this link and open this guide in a new Tab or Window, while keeping this Wiki Guide open.
IMU EVALUATION SOFTWARE FOR THE ADIS16265
After the USB driver installation is complete, connect the EVAL-ADIS USB connector to the PC, using the USB Mini cable, from the EVAL-ADIS kit. LED2 will illuminate as soon as this connection is made. This indicates that the EVAL-ADIS has power and is going through its start-up/initialization process. After the EVAL-ADIS completes its this process, LED1 will illuminate, indicating that it is time to launch the IMU Evaluation application. During the initialization process, several messages may appear on the screen. They are related to updating the EVAL-ADIS firmware and establishing communication between the PC and the EVAL-ADIS. Once LED1 lights up, double click on the IMU_Evaluation.exe file to launch the application.
Main Window
Once the IMU Evaluation software starts-up, the Main Window will appear and look like the following picture. The second picture provides color-coded boxes to support further discussion of each function in this screen.
The orange box identifies the drop-down menus, which provide a number of useful features. The Devices option provides a list of products. For ADIS16265 Evaluation, click on Devices and then select ADIS16265. The green box shows the current device selection, which in this case, identifies the ADIS16265 as the current selection.
The Register Access option provides a listing of user-configurable registers in the ADIS16265 and also provides read/write access to each one of these registers.
The Data Capture option provides the core data collection function.
The Demos option does not support the ADIS16265.
The Tools option provides some diagnostic tools for the USB interface.
The About option provides more detail software revision information.
The purple box identifies the output registers, which update, real-time, after pressing the Read button (see the red box for the location of the Read button).
The yellow box identifies the waveform recorder window. The window contains the gyroscope output (see register titles in the purple box).
Register Access
The purpose of the Register Access window is to provide both read and write access to the user registers in the ADIS16265. The following picture shows the appearance of this window.
The color coded boxes illustrate the different functions that this window provides.
The purple box identifies the register category. In addition to the Control/Status, this drop-down control offers access to Output and Calibration registers.
The red box identifies all of the registers that are in the current category. Click on the register name to select a register for individual read/write access.
The green box identifies the read/write control options for the current register selection. Use the hexadecimal format when writing commands to a particular register.
The yellow box updates all the registers in the current category.
APPLICATION TIP: The Register Access screen writes to user control registers, inside of the ADIS16265, two bytes at a time. So, when configuring a register, make sure to include the hexadecimal number for all 16-bits, before pressing the Write Register button. When using an embedded processor to write to user control registers, inside of the ADIS16265, each command (16-bits) writes to one byte at a time.
Data Capture Menu
The Data Capture function supports synchronous data acquisition, based on the data-ready signal from the ADIS16265. The following picture represents the Data Capture window, right after opening it from the Main Window and the second picture provides color-coded boxes, in order to support further discussion of each function that is associated with this screen.
The red box identifies all of the registers that are eligible for inclusion in the next acquisition process. Click on each box to include a register in the next data acquisition sequence. The box will have a check mark when it has been selected.
The green box identifies the configuration box for the name and location of the data storage file.
The yellow box identifies a number of configuration options for the data acquisition process. The Record Length is a user input for the total number of samples in a data record. Note that all selected registers will have this number of samples in the data record file, after the acquisition process completes. After each update to the Record Length box, the software calculates the displays the total Capture Time. The Add File Header option allows the user to add or remove the header in the data storage file. The Use Scaled Data causes the software to convert the decimal, twos complement number into its representative value. The default setting for Use Scaled Data, option the gyroscope outputs will be in units of degrees/second.
EXAMPLE EXERCISES
This section currently has no ADIS16265-specific content, but the ADIS16448 Evaluation on the EVAL-ADIS Wiki Site has some good examples to start with.
