ADIS1648x EVALUATION ON THE EVAL-ADIS
OVERVIEW
The ADIS1648x MEMS IMU family has three different products: ADIS16480， ADIS16485 and_ADIS16488. All three of these products provide low-profile， high-peformance IMUs that use a serial peripheral interface for data communications. This interface enables direct connection with a large variety of embedded processor products. This electrical connection typically only requires 5 I/O lines for sychronous data collection， as show in the following figure.
ADIS16IMU1/PCBZ BREAKOUT BOARD
The ADIS16IMU1/PCBZ provides a simple method for connecting an existing processor system to the ADIS16480AMLZ， ADIS16485BMLZ or ADIS16488AMLZ， using 1mm ribbon cables. Click on one of the following link for more information on this breakout boards.

EVAL-ADIS: PC EVALUATION
For those who would prefer to perform PC-based evaluation of the ADIS1648x products， before developing their own embedded system， the EVAL-ADIS is the appropriate system to use. The remainder of this Wiki site will focus on PC-based evaluation with the EVAL-ADIS system. Here is a list of equipment required for this:
EVAL-ADISZ
ADIS16488AMLZ
NOTE: Substitute ADIS16480AMLZ or ADIS16485AMLZ for the ADIS16488AMLZ， as needed for specific application requirements.
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.
NOTE: The machine screws that come with the EVAL-ADIS can have a moderate impact on local magnetic fields. For those who need the best performance out of the magnetometer solution， consider replacing them with machine screws that are made out of aluminum or other non-ferrous materials.
NOTE: The following steps represent the most convenient means of attachment， but do not support the “best practices” that are listed in this application note:
ADIS1648x Mounting Guidelines.
PHYSICAL SETUP
The EVAL-ADIS includes a bag of M2x0.4mm machine screws， which include 4 pieces that are in lengths of 16mm and_20mm. Using the 16mm version will only allow for 2mm of penetration into the EVAL-ADIS mouting holes， while the 20mm screws will result in the screws sticking out of the bottom side of the EVAL-ADIS， when fully-secured.
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
Place the ADIS1648x device over the “F” mounting holes and_align its connector with J4 on the EVAL-ADIS.
Step #2
Once the alignment with J4 is correct， gently press the top of the ADIS1648xxMLZ unit down， so that its connector presses into J4. When the connector is fully seated， the ADIS1648xxMLZ will rest on the EVAL-ADIS surface. The following pictures provide a reference of how this setup will look when the ADIS1648xxMLZ has correct alignment with the mating connector on the EVAL-ADIS.
This picture provides an example of the an incorrect connector alignment. Take care to avoid this type of connection error， because it can cause the the ADIS1648xxMLZ to experience harmful conditions. Notice the entire row of gold pins that are outside of the mating connector.
Step #3
Select the mounting screws. The EVAL-ADIS includes a bag of M2x0.4mm machine screws， which include 4 pieces that are in lengths of 16mm and_20mm. Using the 16mm version will only allow for 2mm of penetration into the EVAL-ADIS mouting holes， while the 20mm screws will result in the screws sticking out of the bottom side of the EVAL-ADIS， when fully-secured.
Step #4
Use a screwdriver to secure all four screws into the appropriate mouting holes. Note that difficulty in getting the screws to penetrate the pre-tapped holes can be an indicator of connector misalignment.
Step #5
Set JP1 (EVAL-ADIS) to “+3.3V.”
Step #6
Install header to connect the two pins on JP2. Even if the application does not require use of the RTC function， this connection is necessary to assure reliable operation in the ADIS1648xs processor function.

IMU EVALUATION SOFTWARE OVERVIEW
IMU Evaluation Software installation only requires two simple steps:
1. Download， unzip and_install the EVAL-ADIS USB Driver http://www.analog.com/en/evaluation/EVAL-ADIS/eb.html#SOFTWARE_AND_TOOLS (click here to see the download link)
2. Download， unzip and_copy the IMU_Evaluation*.exe file to the desired location on the test PC (click here to see the download link)
IMU EVALUATION SOFTWARE STARTING POINT
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 (below left) 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 this process， LED1 (below right) 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.
Before Plugging Cable In LED2 = Power OK LED1 = USB Connection Established
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 evaluation of any ADIS1648x product， click on Devices and_then select_the part number (ADIS16488， for example). The green box shows the current device selection， which in this case， identifies the ADIS16448 as the current selection.
The Register Access option provides a listing of user-configurable registers available from the part number selected in the “Devices” drop_down menu. It also provides read/write access to each one of these registers.
The Data Capture option provides the core data collection function.
The Demos option only supports a 3-D rendering tool on the ADIS16480.
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 three waveform recorder windows. The top window contains the three gyroscope outputs. The middle window contains the three accelerometer responses. The bottom window contains the three magnetometer responses. Also， each waveform matches the color of its register (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 ADIS1648x products. 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 Update Registers in Category button (orange box) triggers a read and_display update_of all registers in the current category (red box).
The yellow box identifies the area that provides single-bit command_buttons， such as the ones provided by the GLOB_CMD register.
The Save Reg Settings to File command_saves all of the registers in the current category into a *.csv (common-delimited) file. The Load Reg Settings from File button reads those settings back into the software package and_triggers a routine that updates all registers with the values from this file.
APPLICATION TIP: The Register Access screen writes to user control registers， inside of the ADIS1648x devices， 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 ADIS1648x devices， each command_(16-bits) writes to one byte at a time.
Data Capture
The Data Capture function supports synchronous data acquisition， based on the data-ready signal from the ADIS1648x. 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. The Sample Rate represents the rate that the ADIS1648x updates its output register. This depends on the configuration in the DEC_RATE register. For example， if DEC_RATE = 0x0009， the decimation setting is 10， which would result in an update_rate of 246 SPS. After each update_to the Record Length box， the software calculates the displays the total Capture Time. The Add 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. For example， when enabling Use Scaled Data， the gyroscope outputs will be in units of degrees/second.
