Now, the development board can enter different work mode based on customer operations. If you duplicate the motion: move / tap / shake / rotate the development board to generate activity interrupt -> make the development board stable around two seconds to generate inactivity interrupt three times, the development board will go into SD card data logger mode. Please note that activity and inactivity should always happen in serials and activity should always happen before inactivity. Eink display will give indications during your operations. At the digit unit position, it will show the activity interrupt times. At the digit hundred position, it will show the inactivity interrupt times. Figure 30 shows the eink display when the development board get the first inactivity interrupt after the first activity interrupt. When the development board get the third inactivity interrupt after the third activity interrupt, it will start to check whether the hardware configuration is OK for data logger. Figure 32 shows the hardware configuration is OK for data logger and the development board has entered into data logger mode. Figure 33 shows there is something wrong with hardware configuration for data logger, such as forget to insert SD card, SD card is broken or the supply current is not enough when using a dying external battery. For a new SD card, if you never configure it through ADXL362 DB GUI, it will save ADXL362 output in 2g measurement range and 50Hz output data rate. Figure 32. Eink Display for Entered Into Data Logger Mode Figure 30. Eink Display for First Inactivity Interrupt 8. Figure 31 shows the eink display when the development board get the second inactivity interrupt after the second activity interrupt. Figure 33. Display Bad Configuration for Data Logger 10. Once development board entered into data logger mode successfully, it won’t receive any instructions from ADXL362 DB GUI. If you run the GUI before development board enter into data logger mode, it won’t judge activity and inactivity interrupt anymore. It is recommended to configure SD data logger parameter before saving data with it. To configure data logger parameter, run ADXL362 DB GUI after connecting the Rev. 0 | Page 9 of 14 EVAL-ADXL362Z-DB Evaluation Board User Guide development board with PC through USB. A window similar to the one shown in Figure 34 is displayed. At this point, the functionality of the GUI is completely deactivated. You need to select assigned COM port number for development board as shown in Figure 34, and click Connect. Figure 35. Configurate SD Card Data Logger Parameters Successfully Figure 34. ADXL362 DB GUI Startup 11. After the COM port is connected, the full functionality of the GUI is available for you to use. Note that you should not press the reset button (SW1) while the GUI is running. This causes the development board and the GUI to lose sync and also causes the evaluation system to no longer function properly. Additionally, if for any reason the development board and the GUI do not appear to be properly communicating, you should close the GUI by clicking the Quit Program, reset microcontroller by pressing SW1 and then restart the GUI. 12. Go to SD Data Logger tab, you can configure ADXL362 output data rate (SD data logger frequency is based on this), measurement range, different work mode for power/noise tradeoff, internal low-pass filter pole and self test. After selection, please click Configurate button in Data Logger Parameters Configuration section, if there is no problem with hardware configuration, Figure 35 will be shown. If there is something wrong with the SD card, it will give the warning message to let you check SD card. 13. The saved data on SD card can be viewed and saved to PC by clicking Start button in View & Save SD Data section. This causes many of the options and tabs to be grayed out or to disappear, to prevent software conflicts, until all valid data in SD card has been read or the Stop button in View & Save SD Data section is clicked. The saved acceleration data on SD card then begins to flow across the screen (See Figure 36). At the same time, it allows you to continuously stream the data to eleven .txt file. The first .txt file is named and located by user, the other ten .txt files are named based on the first .txt file and located in the same folder. Eg: If user named DataloggerTest.txt in pop-up dialog box and saved it on desktop, then other ten .txt files which named DataloggerTest_1.txt, DataloggerTest_2.txt, … DataloggerTest_10.txt will be built automatically on desktop. Once SDDataloggerTest.txt saved 64K samples, the following data will be saved in DataloggerTest_1.txt, the rest can be deduced by analogy. When go to the last file DataloggerTest_10.txt, the data will be saved continuously even its size is bigger than 64K samples. If the samples saved in SD card is smaller than 64K, then the files without any data saved will be deleted automatically when all valid data in SD card has been read or the Stop button in View & Save SD Data section is clicked. Each .txt file created contains a header with the date, time, X, Y, Z axes acceleration data, in g, are aligned in tabdelimited columns.

After configuration, you can begin real-time measurement by clicking the View Measurement. This causes many of the options and tabs to be grayed out or to disappear, to prevent software conflicts, until the Stop Measurement button is clicked. The accelerometer output data then begins to flow across the screen. View & Save Measurement performs the same basic function as View & Save SD Data which is introduced in item 13. Figure 36. View and Save SD Card Data on PC 14. After view and save SD Card data on PC, it is recommended to erase SD Card for saving data the next time. To erase SD Card, click Start in Erase SD Card section. Progress bar in Erase SD Card section will show the erase process. It needs around 30ms to erase 256 x 512 bytes data, if there are 1GB valid data saved in SD card, it may need around four minutes to erase. Of course, it needs very long time to save 1GB data. Suppose the output data rate of ADXL362 is 100Hz, it needs to save data continuously around 21 days to generate 1GB 3-axes acceleration data. Figure 37 shows picture once SD card is erased successfully. If there is something wrong with the SD card, it will give the warning message to let you check SD card. Figure 38. Real Time Data Tab 16. ADXL362 DB GUI also support inclinometer demo. Go to Inclinometer tab, read the notes firstly. Then, put the development board on table flatly to make it parallel with the ground (z axis in 1g field), click Offset Calibration button, wait around 10 seconds to finish offset calibration. After that, click Start Tilt Sensing button to test the development board tilt angle (please try to make z axis in 0g filed when playing tilt sensing). You can click Stop Tilt Sensing button to stop tilt sensing function at any time (See Figure 39). Figure 37. Erase Finished and Successfully 15.

Figure 1 shows EVAL-ADXL362Z-DB various connection for different purposes. Firstly, the EVAL-ADXL362Z-DB could be configured as a portable data logger to save essentially unlimited acceleration data onto a MicroSD. User can select different acceleration output data rate, measurement range, etc. based on different applications to save. These raw data can be used for refining algorithms, tuning thresholds, and generally familiarizing oneself with accelerometer data. Figure 39. Inclinometer Demo 17. It is recommended to power development board through USB as described in Figure 29 when evaluating ADXL362 DB GUI. For data logger, it is recommended to use high capacity AAA batteries or lithium thin cell to power the development board, and thus it integrates seamlessly into portable applications as shown in Figure 40. Secondly, the EVAL-ADXL362Z-DB could be used to verify user finalized solution. Take pedometer as an example, you can tie the development board on wrist/arm/ankle, hold in hand or put in pocket, then walk or run and show the steps on the eink display. You can check the solution accuracy intuitively. At the same time, you can check the current consumption of your solution with multi-meter. The development board offer three optional current: accelerometer itself, system current without display (accelerometer + microcontroller), system current with display (accelerometer + microcontroller + display) for measurement. Thirdly, the EVAL-ADXL362Z-DB could be configured to communicate with PC. Then, user can view and save the real time output of ADXL362 on PC, configure data logger parameters and realize demo that does not have to be portable, like inclinometer. POWER SUPPLIES Figure 40.
