This demo will use EVAL-ADXL372-ARDZ along with EVAL-ADICUP3029 to create a impact measurement application. The ADXL372 is an ultralow power, 3-axis, ±200 g MEMS accelerometer.
The ADXL372 demo project uses the EVAL-ADXL372-ARDZ shield which has an ADXL372 accelerometer. The ADXL372 is configured to operate in “Instant On” mode which means that the device is powered down, until the sensor records an impact event that triggers a threshold. Once that level is surpassed, the ADXL372 automatically goes into measurement mode to capture the rest of the impact event.
The EVAL-ADICUP3029 is designed for IOT (Internet of Things) applications in mind, and therefore comes with on board Bluetooth 5.0 module. The ADuCM3029 is placed in “Plexi” mode, to optimize it's ultra low power consumption and can only be woken up from an external interrupt that comes from the ADXL372 impact sensor. At that point the ADuCM3029 is placed into full power mode to do the other application tasks necessary, before being placed back into “Plexi” mode.
The data is sent via Bluetooth 5.0 link to an iOS smart device, where all the max impact data can be read.
Both boards and all components are used in their respective low power modes to optimize the solutions battery life.
The following is a list of items needed in order to replicate this demo.
The data from the accelerometer will be sent over Bluetooth but can also be viewed using a UART connection.
To establish connection over UART, a micro USB cable connected to the board and a serial console program like Putty are required.
Following is the UART configuration.
Select COM Port Baud rate: 9600 Data: 8 bit Parity: none Stop: 1 bit Flow Control: none
Open up the IoTNode app on your Smart Phone or Tablet.
Just press the Scan button on the bottom left corner in order for the app to start searching for Bluetooth devices.
Once the device is visible press connect to access the information provided over Bluetooth.
After connecting to the device and generating enough G acceleration(minimum of 10 G on any axis), information will be displayed on the application. To generate this high value of acceleration you can try and hit the board on your hand ( do not put to much force in order to avoid damages to the device ).
There are two basic ways to program the ADICUP3029 with the software for the ADXL372.
Using the drag and drop method, the software is going to be a version that Analog Devices creates for testing and evaluation purposes. This is the EASIEST way to get started with the reference design
Importing the project into CrossCore is going to allow you to change parameters and customize the software to fit your needs, but will be a bit more advanced and will require you to download the CrossCore toolchain.
