GETTING STARTED

 

Figure 17: ADXRS450 Evaluation GUI Startup Screen

Before running the software evaluation GUI, it is a good idea to 
reset the ISEB by pressing the SW2 button described in the 
previous section.  This will remove any errors which could be 
lingering due to an improper shutdown or disconnection from 
the PC. 
After the completion of the Software GUI installation routine, a 
shortcut to launch the executable will be added to the PC’s start 
menu.  To launch the evaluation GUI, simply click on Start > 
All Programs > ADXRS450 Evaluation Software > ADXRS450 
Eval.  The user should then be shown a similar screen as that 
presented in Figure 14. 
At this point the functionality of the GUI is completely 
deactivated.  Before testing any devices, the user must associate 
the software GUI with the previously installed hardware 
through the COM port.   Refer to the PC’s Device Manager, 
under the Ports (COM & LTP) submenu in order to determine 
which COM port has been assigned to the ADI Inertial Sensor 
Evaluation System.  Select this COM port from the drop down 
menu, and click “Confirm COM” to begin using the GUI. 

Once the COM port is confirmed, the full functionality of the 
software evaluation GUI will become available to the user.  The 
following sections will detail the intent of each panel of the 
GUI.  The user can exit the GUI at any time by pressing the 
Quit Program button located in the lower right of the window. 
 

Important Note:

  Do not press the reset button (SW2)  while the 

GUI is running.  This will result in the ISEB and the Software 

GUI losing sync, and the evaluation system will no longer 

function properly.  Additionally, if for any reason the ISEB board 

and the software evaluation GUI do not appear to be properly 
communicating, the following reset routine should be performed: 

1.

 

Close the software GUI by pressing the “QUIT 
PROGRAM” button or by selecting File -> Exit.  

 

2.

 

With the Software GUI closed, reset the ISEB evaluation 

board by pressing the reset button (SW2).

 

3.

 

Restart the software GUI
