Supported commands

The EK3LV02DL board is equipped with a dedicated firmware which supports a set of

commands that allow to control the 3-axis digital output MEMS sensor mounted on the

board and to acquire the measured acceleration data.

The firmware handles also the communication between the EK board and the PC through

the USB bus. Through the usage of these commands it is possible to control the 3-axis

digital output MEMS sensor mounted on the board and to acquire the measured

acceleration data, thus allowing the user to easy write his/her own applications which exploit

the mounted accelerometer.

This section describes the commands that are supported by the firmware loaded onto the

microcontroller of the EK3LV02DL Evaluation Kit.

7.1

Getting Started

Before using the commands described in the next paragraphs, the following procedure must

be performed:

1.

Connect the EK3LV02DL to the USB port

2.

Start an appropriate software which allows to send the command through the Virtual

serial port. The remaining part of this document will suppose the usage of the “Hyper

Terminal”.

3.

Create a new connection; for example name it “EK3LV02DL” and click OK;

4.

In the “Connect Using” field select the right Virtual COM port onto which the USB port

has been mapped.

5.

Set the port to 115200 Bit per second, 8 Data bits, Parity None; 1 Stop bit, Flow control

None and then click OK.

6.

In the Hyper Terminal select “Files > Properties > Settings” and then click onto the

“ASCII Setup” button.

7.

Select “Send line ends with line feeds” and “Echo typed characters locally”.

8.

Click onto OK button to close the “ASCII Setup” window.

9.

Click onto OK button to close the “Properties” window.

Once this procedure has been completed the user can send to the EK3LV02DL the

commands described in the following sections by typing the commands themselves in the

“Hyper Terminal” window.
