UPDATE NOTICE: This Wiki Guide covers the use of evaluation tools (ADIS16210/PCBZ and EVAL-ADISZ) that are no longer available for purchase, but it remains online to support those who already have these tools. For all new ADIS16210 users, please go to the ADIS16210's product page, then click on Evaluation Kits and then click on the See All tab to review a listing of the most current ADIS16210 evaluation tools. Thank you!
The ADIS16210 iSensor® is a digital inclinometer system that provides precise measurements for both pitch and roll angles over a full orientation range of ±180°. It combines a MEMS tri-axial acceleration sensor with signal processing, addressable user registers for data collection/programming, and a SPI-compatible serial interface. The electrical connection typically only requires 5 I/O lines for synchronous data collection, as shown in the following figure:
For those who are on a tight timeline, connecting the ADIS16210 to an embedded controller will provide the most flexibility in developing application firmware and will more closely reflect the final system design. The ADIS16210/PCBZ is the breakout board for the ADIS16210 and may provide assistance in the process of hooking it up to an existing embedded processor system.
For those who would prefer to perform PC-based evaluation of the ADIS16210, 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.
Windows XP, Vista, 7
.NET Framework 3.5
NOTE: Newer versions of the .NET framework do not currently support the IMU Evaluation software package.
The ADIS16210/PCBZ provides the ADIS16210 on a small printed circuit board (PCB) that simplifies the connection to an existing processor system. This PCB includes a silkscreen, for proper placement, and four mounting holes that have threads for M2 × 0.4 mm machine screws. The second set of mounting holes on the interface boards are in the four corners of the PCB and provide clearance for 4-40 machine screws. The third set of mounting holes provides a pattern that matches the EVAL-ADIS evaluation system, using M2 × 0.4mm × 4 mm machine screws. These boards are made of IS410 material and are 0.063 inches thick. J1 is a 16-pin connector, in a dual row, 2 mm geometry that enables simple connection to a 1 mm ribbon cable system. For example, use Molex P/N 87568-1663 for the mating connector and 3M P/N 3625/16 for the ribbon cable. For direct connection to the EVAL-ADIS evaluation system, use these parts to make a 16-pin cable or remove pins 13, 14, 15 and 16. The LEDs (D1 and D2) are not populated, but the pads are available to install to provide a visual representation of the DIO1 and DIO2 signals. The pads accommodate Chicago Miniature Lighting Part No. CMD28-21VRC/TR8/T1, which works well when resistors R1 and R2 are approximately 400 Ω (0603 pad sizes).The mating connector for the ADIS16210, J2, is AVX P/N 04-6288-015-000-846. The picture below provides a close-up view of this connector, which clamps down on the flex cable to press its metal pads onto the metal pads inside the mating connector. The schematic is for the ADIS16210/PCBZ board.
NOTE: Do not plug the EVAL-ADIS into the USB cable at this stage of the setup. Wait until the software installation is complete.
Slide the ADIS16210CMLZ part into the mating J2 connector on the ADIS16210/PCBZ. Press the J2 clamp down onto the flex connector to complete the ADIS16210CMLZ part connection to the ADIS16210/PCBZ. Then secure the part using the M2 × 0.4mm × 4 mm machine screws provided with the ADIS16210/PCBZ. The following pictures provide a visual reference for correct connection but are actually ADIS16228CMLZ parts that share the same mechanical body.
Mounting to the system frame is accomplished using 4 M2 x.4 x 6mm machine screws included with the ADIS16210/PCBZ. The mounting location holes are marked as an example in the picture below. Use the 4 holes to secure the ADIS16210/PCBZ to the EVAL-ADIS.
NOTE: If JP1 is left on +5v the software will look like the following picture. Move JP1 to the+3.3V setting to correct the problem.
Click here to download the IMU Evaluation software to a personal computer, which enables PC-based evaluation of the ADIS16210 on an EVAL-ADIS evaluation system. The download file will contain three separate files: The USB drivers (SDPDrivers.exe), the application file (IMUEvaluation.exe) and the revision table. Copy these files to a convenient folder for running the application from.
The SDPDrivers.exe file contains USB drivers that are compatible with both 32-bit and 64-bit Windows systems. Double-click on the SDPDrivers.exe file and follow the prompts to install the USB driver files onto the PC. When the following window appears, click on Next and then click on Install to continue with the installation.
The following pictures show the progress bar and the final confirmation window. Click on Finish to complete the installation.
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 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.
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 ADIS16210 Evaluation, click on Devices and then select ADIS16210. The green box shows the current device selection, which in this case, identifies the ADIS16210 as the current selection.
The Register Access option provides a listing of user-configurable registers in the ADIS16210 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 ADIS16210.
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 two 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).
The purpose of the Register Access window is to provide both read and write access to the user registers in the ADIS16210. 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 ADIS16210, 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 ADIS16210, each command (16-bits) writes to one byte at a time.
The Data Capture function supports synchronous data acquisition, based on the data-ready signal from the ADIS16210. 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 boxes identify 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.
