  GENERAL DESCRIPTION
  This user guide provides an overview of using the EVAL-ADIS-MCBZ, including instructions for the motion capture board (MCB) hardware setup and software functions. The EVAL-ADIS-MCBZ supports a wide array of Analog Devices, Inc., sensor families (ADXL, ADIS, and ADXRS). It easily communicates with sensors and captures data by connecting the hardware to a PC and running the evaluation software. The graphical user interface (UI) of the software allows plotting and storing sensor data for postcapture analysis.

EVALUATION BOARD PHOTOGRAPH
The MCB is shown from the top and angle view in Figure 1 and Figure 2, respectively.

HARDWARE SETUP

The most common hardware setup includes the MCB, USB cable, and the sensor (through the evaluation board (EB) or breakout board (BB)). A battery and SD card can be added to the MCB for saving the data independently from the PC platform. Figure 3 represents the hardware and two different sensors which have different boards (EB and BB). It is important to note that only one sensor can be connected to the MCB at a time, either through the EB or BB sensor connectors.In Figure 3, the EB and BB interface connectors are located in the upper left side of the MCB. On the MCB silkscreen, P5 identifies the BB interface connector, and P6 and P7 identify the EB interface connector. The EB connector has two 10-pin single-row connectors. For the BB connector, the M55-7003242R from HARWIN was used as a lock connector which has 32 pins with 1.5 mm pitch. By connecting the sensor to the MCB and the USB cable to the computer, the hardware setup is ready to communicate with the software. The next sections show the software setup and installa-tion.

CONNECTING TO THE HARDWARE
Starting from the main screen in the UI, connect to the MCB using the following steps:

1.  Click the scan button to search for the available COM ports.
2.  Select the desired COM port. If the EVAL-ADIS-MCBZ is connected to the PC, the COM port list is updated and the EVAL-ADIS-MCBZ is shown as ADI MCB, followed by eight characters that correspond to the microcontroller serial number.
3. Click the connect button.
   After connecting to the MCB, the sensor family and part number show up on the top right tab. Figure 6 shows the sensor connection and recognition icons.

When the system recognizes the sensor, the Register Map and Basic Configurations tabs fill with the corresponding sensor con-figuration options. Both tabs are on the right side of the UI. Figure 7 shows the settings in the Basic Configurations and Register Map tabs.
analog.com

Once initial configurations are completed, for certain sensors within the same family that lack a specified register for precise model detection, select the part number through the sensor combo box located on the top right side of the UI. Incorrect configuration of the sensor model may result in data being displayed on the graphs with incorrect scaling.

UI TABS
The UI provides an environment for visualizing and analyzing sensor data which consists of five tabs labeled Real Time, Full View, Data Analysis, Allan variance, 3D, and Load .adr File. The first three ones and the 3D tab are dedicated to online COM port data from the MCB. The next sections explain each tab and its feature in detail.

Sensor Operational Mode
Once the sensor connects and powers up, it enters Standby mode by default. To start data capturing or analysis, select the desired operational mode from the Operating Mode dropdown list in the Basic Configurations tab. Figure 8 shows the different operational modes for two different sensors (the ADXL355 and the ADXL382).
Figure 8. Operation Mode

Real Time Tab
Click the Real Time tab to capture and display data in the UI once the sensor is in Measurement mode. Click View rate to select the sample rate for the display, and click Time Scope to establish the length of the time record to display in the UI. The sample rate (View rate setting) may need adjustment, based on the bandwidth of the computing platform. Figure 9 shows the View rate and Time Scope tabs and their different values for ADXL355.

Full View Tab
Use this tab to capture acceleration data (in all axes), temperature, and interrupt pin status over time. Select the buffering type accord-ing to preference. The following three buffering methods are:

• Manual buffering: click Start Buffering to begin data capture. Click Stop and Draw Charts to stop capturing and display the data for the specified time duration.
• Single buffering: define the buffering time, then click Start Buffering to capture data for that duration. The system stops automatically after the set time.

Periodic buffering: select this option to repeat single buffering periodically.
Figure 10 shows the buffering options.

Figure 11 shows an example of Single buffering for the buffering time of 5 seconds. The acceleration in x-, y-, and z-axis and the interrupt (data ready in this case) are shown in Figure 11.

The View rate and Time Scope boxes do not apply to this tab. The buffering time is controlled using the three buffering options.

Data Analysis Tab
To explore the captured data in the frequency domain, click the Da-ta Analysis tab. It uses the fast Fourier transform (FFT) algorithm for frequency analysis. Data can be buffered with the three methods discussed in the Full View Tab section. Select between FFT and PSD modes using the corresponding radio buttons on the UI. The square root of the PSD is shown in the PSD tab. Figure 12 shows the Data Analysis tab for a sample case, displaying a frequency of 200 Hz for acceleration in the direction.

Allan Variance Tab
The Allan variance tab generates root Allan variance plots by loading pre- recorded time domain data in .csv format.
Figure 13 shows an example of a root Allan variance curve obtained for the ADXL357 accelerometer. Notice that the velocity random walk (VRW) and bias instability (BI) are computed from the loaded data set as well, and displayed as an array formatted as X-axis, Y-axis, and Z-axis. Similarly, for gyroscopes, the angle random walk and BI are computed.

3D Tab
Click the 3D tab to display a three-dimensional cube representing the sensor position within the XYZ (Cartesian) coordinate system, showing changes over time. Real-time values for acceleration and rotation are also visible in this tab, providing immediate feedback on the sensor orientation and movement.

Calibration Tab
This tab allows a quick and easy way to perform offset and sensitivity calibration for accelerometers and inertial measurement units
(IMUs) by leveraging the acceleration of gravity. Follow these steps for the calibration procedure:

1. Enter the local latitude, longitude, altitude, and heading of the location where the calibration is performed. This serves to fine tune the calibration to the local gravity field.

2.  Click the Start Record button.

3.  Position the EVAL-ADIS-MCBZ board in different directions so that at least a positive and negative reading on each axis is recorded. For a 3-axial accelerometer, it is recommended, at least, to position the board so that each axis reads approximately +1g and −1g. Figure 16 shows three sample directions for the +1g acceleration along three different axes. The more positions are recorded, the more accurate the calibration is. Make sure to hold each position for at least three seconds for the calibration algorithm to work properly.

4. Stop the recording. A .csv file with the naming convention SensorName_CRD_year-month-day_hour-minute-second is created, as shown in Figure 17, where the sensor connected is the ADXL359. This file contains the time domain data from start to finish of the recording.

5. Notice that the Calibration files text box can contain multiple calibration files. Select the appropriate file and click Start Calibration. The following two types of calibration files are created (see Figure 18

   •  A .bin file that is used to load the calibration coefficients into the EVAL-ADIS-MCBZ board and apply all necessary compensations.
   •  A .txt file that contains a report of the calibration results. The calibration report is displayed on the right hand side of the UI, intermediately after the calibration is completed. click the To MCB button to upload the calibration coefficients to the EVAL-ADIS-MCBZ board.
