If you've never used ANY of Analog Devices' Inertial Sensor Evaluation Kits before*, start here! *This includes any of EVAL-ADXL###Z-M , EVAL-ADXRS###Z-M and EVAL-ADXL###Z-MLP . |
Prior to starting the GUI, plug in the system:
Connect the motherboard to the satellite board via the ribbon cable.
Then, connect the motherboard to the computer via the USB cable.
The ADI installer places a shortcut to the GUI in the Start menu under All Programs
→ Analog Devices - Inertial Sensor Eval
, as shown below. Click on this shortcut to start the evaluation system GUI.
The GUI starts up grayed out with all functions disabled. Before testing any devices, you must associate the software GUI with the installed hardware by selecting the appropriate COM port from the menu in the lower left corner. Follow these instructions if you do not know which COM port to use.
Selecting the appropriate COM port and clicking Connect should enable all GUI functionality.
To end the program, click the “Quit Program” button at the bottom right corner of the GUI screen, and then use the X at the top right to close the window.
In no particular order, here are a few tips for troubleshooting the system when things aren’t working:
The ADXL362 Evaluation System GUI includes 4 tabs for evaluation of various paramaters:
Real-time data: | View and save real-time acceleration measurements under user-input settings. |
Power consumption: | View real-time power consumption under user-input settings. |
Temperature: | View the effect of temperature on acceleration output. |
Configuration: | Write to and read from device registers. |
The Real Time Data tab configures the inertial sensor evaluation system and the ADXL362 for real-time acceleration monitoring. The tab contains an oscilloscope-like interface that you can use to view the output of the accelerometer and adjust the relevant parameters, such as output data rate, measurement range, output format, different work mode for power/noise tradeoff and Self Test (see figure above).
Configuration options:
Functionality:
View Meas
button. This causes many of the options and tabs to be grayed out or to disappear, to prevent software conflicts, until the Stop Meas button is clicked. The accelerometer output data then begins to flow across the screen. View & Save Meas
button.
When this button is clicked, the user is prompted to specify a file name and location for saving the data. Data is saved into a tab-delimited .txt file. The first row of the file always contains column labels denoting Date, Time, X, Y, and Z (for acceleration data in g).
The Save functionality is capable of saving unlimited data. To keep file size manageable, the data is split up into up to 11 separate .txt files. The first 10 files have a capacity of 64000 samples. The 11th file will contain all remaining data.
The name and location of the first .txt file are specified by the user upon clicking the View & Save Meas
button. All 11 files are created as soon as the first file name and location are specified. Consecutive numeric suffixes are appended to the specified file name, and all 11 files are saved to the same location. For example, if the first file is named ADXL362Test.txt
and saved to the desktop, then 11 files will be automatically created on the desktop: ADXL362Test.txt
, ADXL362Test_1.txt
, …, ADXL362Test_10.txt
. Files will be filled in order as data becomes available. When measurement is stopped (via the GUI), empty files are automatically deleted.

tab above the graph.When used properly, the ADXL362 offers extremely low system-level power consumption in addition to its own device-level power savings. A deep FIFO, robust motion (and lack-of-motion) detection, and autonomous interrupt processing allow the accelerometer to operate as a motion sensor and a power manager without the intervention of a host processor. The Power Consumption tab is designed to highlight some of the ADXL362's system-level power savings features.
The following functionality is available to you within the Power Consumption tab:
