Post event logger stage

The post event logger stage is used to download the logged data in the computer and

compare this data.

Below are the steps for the post event logger stage:

1.

Put the switch SW4 into the downward position, as shown in Figure 11.

2.

Connect the RFID reader to the computer.

3.

Place the STEVAL-IPR002V1 on the RFID reader, as shown in Figure 12.

4.

Open the GUI application.

5.

Press the “Connect” button, as shown in Figure 6. It shows the message “Board is

connected”. If the board is not connected, close and reopen the GUI, and press the

“Connect” button again.

6.

Click on the “Download from the DataLogger/EventLogger” tab, as seen in the bottom

of the GUI window, as shown in Figure 15. A GUI window, as seen in Figure 8, opens.

7.

Press the “Get DataLogger/EventLogger” button on the GUI window.

8.

The window shows the values for different sensors on the GUI. These values, as seen

on the GUI, are the last stored values of the sensors. Each sensor also has a log count

which shows the number of values logged for that sensor.

9.

Figure 8 shows the condition.

10. Click on the “Graph Plot” tab at the bottom of the GUI window.

11. This opens the plotter window shown in Figure 16. Select the sensor whose plot is to

be seen and then click the “Plot” button.

12.

13. Double click on the plot to expand it. To exit from the expanded plot, again double click

on it and it returns to step 10.

14. To zoom in, use the scroll up on the mouse or the '+' button on the keyboard, and to

zoom out use the scroll down on the mouse or the '-' button on the keyboard. To slide

the graph right or left, click on the graph, left click on the mouse and slide to the right

side or left side.

15. To store the data in .xls, click on the “Save Plot” button and save the xls file.

Note:

The event logger mode logging time is recorded as hours and minutes only. Seconds are not

recorded inside the EEPROM. Therefore the plot shows values on a minute scale only.
