Connecting to Virtual the COM port

Before using the functions of the Evaluation Kit Software it is necessary to open the

connection with the EK3LV02DL board. This is achieved through the following procedure:

1.

Connect the EK3LV02DL to desired USB port;

2.

In the pop-menu “USB ---> Virtual COM” choose the Virtual COM number on which the

board has been mapped. For additional information on how to get this value check

section 2.3.

3.

Open the connection by clicking on “Connect” (Figure 9 ref2). Once this procedure is

completed, the General Purpose LED of the board will switch from red to green.

Once the procedure has been completed, the user can acquire, plot and save the

acceleration data measured by the sensor and he/she can access the content of the

registers embedded in the device. Further details about each single function are provided in

the sections hereafter.

Note:

Due to Virtual COM driver communication speed limits, the maximum Output Data Rate allowed for the

device is 640 Hz. Higher Output Data Rate could result in a possible data loss.

Registers Read/Write

Through the “Register Read/Write” panel (Figure 9, ref3), the user can either directly write

or read the registers value inside the LIS3LV02DL device.

In particular, by clicking on the “Read/Write” button a new window appears (Figure 10).

To perform a register read out, the user must select the desired register name into “Reg

Name” pop up menu (ref4) and then he/she must click on the “Read” button (ref2). The

result of the reading will appear in the text box “Reg Value” (ref3).

To write a data into a register, the user must select the desired register name (ref4), choose

the desired value in the text box “Reg Value” (ref3) and then click on the “Write” button

(ref1). In case of read-only registers, the write button is not enabled.
