UPDATE NOTICE: This Wiki Guide covers the use of an evaluation tool (EVAL-ADISZ) that is no longer available for purchase, but this Wiki Guide remains online to support those who already have these tools. For all new ADIS16209 users, please go to the ADIS16209's product page, then click on Evaluation Kits and then click on the See All tab to review a listing of the most current ADIS16209 evaluation tools. Thank you!
The ADIS16209 is a high accuracy, digital inclinometer that accommodates both single-axis (±180°) and dual-axis (±90°) operation. The standard supply voltage (3.3 V) 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 acceleration, accurate incline angles, 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:
For those who are on a tight timeline, connecting the ADIS16209 to an embedded controller will provide the most flexibility in developing application firmware and will more closely reflect the final system design. The ADIS16209/PCBZ is the breakout board for the ADIS16209 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 ADIS16209, 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 EVAL-ADIS16209 provides the EVAL-ADIS16209 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 ADIS16209/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.
Connect the ADIS16209/PCBZ to the EVAL-ADIS, using the ribbon cable (comes with EVAL-ADIS) and J1 on both boards. J1 on both boards share common pin assignments, for pins 1 through 12. So, make sure that the ribbon cable connects pins 1-12 on both J1 connectors.
Connect J2-11 (ADIS16209/PCBZ) to the DIO1 test point on the EVAL-ADIS. This is the data-ready signals, which is what the IMU Evaluation Software uses to synchronize the data acquisition with data sampling in the (ADIS16209/PCBZ), when using the Data Capture menu. See the section on Advanced Options for more details on triggering controls.
Mounting to the system frame is accomplished using 4 M2x.4x4mm machine screws included with the ADIS16209/PCBZ. The mounting location holes are marked as an example in the picture below. Use the 4 A-location holes to secure the ADIS16209/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 ADIS16209 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 ADIS16209 Evaluation, click on Devices and then select ADIS16209. The green box shows the current device selection, which in this case, identifies the ADIS16209 as the current selection.
The Register Access option provides a listing of user-configurable registers in the ADIS16209 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 ADIS16209.
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 gyroscope outputs. The bottom window contains the 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 ADIS16209. 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 ADIS16209, 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 ADIS16209, 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 ADIS16209. 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.
The only Advanced Options control option that is relevant for the ADIS16209 is the option for enabling or disabling the Data Ready Synchronization Enabled function. When this is checked, Data Capture leverages the data-ready signal to trigger data acquisition. When this option is unchecked, Data Capture will be asynchronous with ADIS16209 data production.
NOTE: The option Use External Trigger will appear in this screen, but since the ADIS16209 does not provide an external clock input function, this option does not apply to the ADIS16209.
