+====== ADIS16375 EVALUATION ON THE EVAL-ADIS=====
+===== OVERVIEW =====
+The [[adi>ADIS16375|ADIS16375]] iSensor® is a complete inertial system that includes a triaxis gyroscope and triaxis accelerometer. Each sensor in the [[adi>ADIS16375|ADIS16375]] combines industry-leading iMEMS® technology with signal conditioning that optimizes dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, alignment, and linear acceleration (gyro bias). As a result, each sensor has its own dynamic compensation formulas that provide accurate sensor measurements over a temperature range of −40°C to +105°C.
+The [[adi>ADIS16375|ADIS16375]] provides a simple, cost-effective method for integrating accurate, multiaxis, inertial sensing into industrial systems, especially when compared with the complexity and investment associated with discrete designs. All necessary motion testing and calibration are part of the production process at the factory, greatly reducing system integration time. The SPI port typically connects to a compatible port on an embedded processor, using the connection diagram below. The four SPI signals facilitate synchronous, serial data communication. Connect RST to a digital I/O line for remote reset control or leave it open for normal operation. The factory default configuration provides users with a data-ready signal on the DIO2 pin, which pulses high when new data is available in the output data registers.

+===== ADIS16375/PCB BREAKOUT BOARD =====
+For those who are on a tight timeline, connecting the [[adi>ADIS16375|ADIS16375]] to an embedded controller will provide the most flexibility in developing application firmware and will more closely reflect the final system design. The [[adi>en/mems-sensors/mems-inertial-measurement-units/adis16375/products/EVAL-ADIS16375/eb.html|ADIS16375/PCBZ]] is the breakout board for the [[adi>ADIS16375|ADIS16375]] and may provide assistance in the process of hooking it up to an existing embedded processor system.
+===== ADISUSB: PC EVALUATION =====
+For those who would prefer to perform PC-based evaluation of the [[adi>ADIS16375|ADIS16375]], before developing their own embedded system, the [[adi>EVAL-ADIS|EVAL-ADIS]] is the appropriate system to use. The remainder of this Wiki site will focus on PC-based evaluation with the [[adi>EVAL-ADIS|EVAL-ADIS]] system.
+===== EQUIPMENT LIST =====
+[[adi>EVAL-ADIS|EVAL-ADIS]]
+[[adi>en/mems-sensors/mems-inertial-measurement-units/adis16375/products/EVAL-ADIS16375/eb.html|ADIS16375/PCBZ]]
+===== SYSTEM REQUIREMENTS =====
+Windows XP, Vista, 7
+.NET 3.5 Framework
+===== PHYSICAL SETUP =====
+The [[adi>en/mems-sensors/mems-inertial-measurement-units/adis16375/products/EVAL-ADIS16375/eb.html|ADIS16375/PCBZ]] includes one interface PCB, 4 M2x.4x18mm machine screws and one [[adi>ADIS16375|ADIS16375AMLZ]] unit. The [[adi>ADIS16375|ADIS16375]] is approximately 44 mm × 47 mm × 14 mm and provides a flexible connector interface that enables multiple mounting orientation options. Set the interface PCB aside, as it is not used for connecting the [[adi>ADIS16375|ADIS16375AMLZ]] to the [[adi>EVAL-ADIS|EVAL-ADIS]].
+NOTE: Do not plug the [[adi>EVAL-ADIS|EVAL-ADIS]] into the USB cable at this stage of the setup.  Wait until the software installation is complete.
+=== Step #1 ===
+Place the ADIS16375 device over the "F" mounting holes and align its connector with J4 on the [[adi>EVAL-ADIS|EVAL-ADIS]].
+{{:resources:eval:user-guides:inertial-mems:imu:375-connector-pinout.png?300 |}}
+{{:resources:eval:user-guides:inertial-mems:imu:375-hole-mnt-dimension.png?300|}}
+{{:resources:eval:user-guides:inertial-mems:imu:adis16480-eval-adis-holelocations.png?500|}}
+{{:resources:eval:user-guides:inertial-mems:imu:375-correct-j4-connection.png?500|}}
+WARNING: Make sure that the connector is in proper alignment before pressing it in. Misalignment can cause pin damage and exposure to harmful conditions.
+{{:resources:eval:user-guides:inertial-mems:imu:375-correct-j4-connection.png?600 |}}
+=== Step #2 ===
+Once the alignment with J4 is correct, gently press the top of the ADIS16375AMLZ unit down, so that its connector presses into J4. When the connector is fully seated, the ADIS16375AMLZ will rest on the EVAL-ADIS surface.  The following pictures provide a reference of how this setup will look when the ADIS16375AMLZ has correct alignment with the mating connector on the [[adi>EVAL-ADIS|EVAL-ADIS]].
+{{:resources:eval:user-guides:inertial-mems:imu:adis1648x_evaladis_install_step01-02.jpg?400|}}
+{{:resources:eval:user-guides:inertial-mems:imu:adis1648x_evaladis_install_step01-02b.jpg?400|}}
+=== Step #3 ===
+Select the mounting screws. The [[adi>EVAL-ADIS|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.
+{{:resources:eval:user-guides:inertial-mems:imu:adis1648x_evaladis_install_step01-04.jpg?400|}}
+=== 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. The suggested torque setting for the attachment hardware is 40 inch-ounces, or 0.2825 N-m.
+{{:resources:eval:user-guides:inertial-mems:imu:adis1648x_evaladis_install_step01-05.jpg?400|}}
+=== Step #5 ===
+Set the jumper JP1 on the ([[adi>EVAL-ADIS|EVAL-ADIS]]) to the **+3.3V** position setting for the [[adi>ADIS16375|ADIS16375AMLZ]]. The following picture shows JP1 in the **+3.3V** position

+{{:resources:eval:user-guides:inertial-mems:imu:eval-adis-usbdriverinstall-04.png?nolink&445|}}
+===== IMU EVALUATION SOFTWARE GUIDE =====
+After the USB driver installation is complete, connect the [[adi>EVAL-ADIS|EVAL-ADIS]] USB connector to the PC, using the USB Mini cable, from the [[adi>EVAL-ADIS|EVAL-ADIS]] kit. LED2 will illuminate as soon as this connection is made. This indicates that the [[adi>EVAL-ADIS|EVAL-ADIS]] has power and is going through its start-up/initialization process.  After the [[adi>EVAL-ADIS|EVAL-ADIS]] completes 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 [[adi>EVAL-ADIS|EVAL-ADIS]] firmware and establishing communication between the PC and the [[adi>EVAL-ADIS|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.
+{{:resources:eval:user-guides:inertial-mems:imu:375-eval-adis-main-screen-software.png?445|}}
+{{:resources:eval:user-guides:inertial-mems:imu:375-eval-adis-main-screen-defined.png?445|}}
+The orange box identifies the drop-down menus, which provide a number of useful features. The **Devices** option provides a list of products. For [[adi>ADIS16375|ADIS16375]] Evaluation, click on **Devices** and then select **ADIS16375**. The green box shows the current device selection, which in this case, identifies the [[adi>ADIS16375|ADIS16375]] as the current selection.
+The **Register Access** option provides a listing of user-configurable registers in the [[adi>ADIS16375|ADIS16375]] 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 [[adi>ADIS16375|ADIS16375]].
+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 bottom window contains the three accelerometer 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 [[adi>ADIS16375|ADIS16375]]. The following picture shows the appearance of this window.
+{{:resources:eval:user-guides:inertial-mems:imu:375-eval-adis-registers.png?600|}}
+The color coded boxes illustrate the different functions that this window provides.
+{{:resources:eval:user-guides:inertial-mems:imu:375-eval-adis-registers-defined.png?600|}}
+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 the 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 [[adi>ADIS16375|ADIS16375]], 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 [[adi>ADIS16375|ADIS16375]], 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 [[adi>ADIS16375|ADIS16375]].  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.
+{{:resources:eval:user-guides:inertial-mems:imu:375-eval-adis-datalog.png?445|}}
+{{:resources:eval:user-guides:inertial-mems:imu:375-eval-adis-datalog-defined.png?445|}}
+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 [[adi>ADIS16375|ADIS16375]] updates its output register. This depends on the configuration in the SMPL_PRD {12:8] bits. For example, if SMPL_PRD = 0x0801, bits 12:8 represent a decimation setting of 8, which would result in an update rate of 102.5 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.
