3.

Place the data logger board (STEVAL-IPR002V1) on the reader, as shown in

Figure 12.

4.

Open the event/data logger GUI application.

5.

Press the “Connect” button on the GUI, as shown in Figure 6. The information message

for board connection is seen on the GUI, as shown in Figure 13. If the message is

“Board is not connected” then again place the data logger board properly near the

RFID reader and press the “Connect” button.

6.

Click on the “Event Logger Selection” button, as shown in Figure 6. The GUI window for

the event logger opens as shown in Figure 10.

7.

Select the sensors whose values are to be logged in the “Select” section of the GUI.

Click on the check box to select the sensor.

8.

Enter the maximum and minimum values for the temperature sensor and the humidity

sensor. Light and vibration can have 5 different levels for the thresholds which can be

selected from the dropdown menu. If the sensors are not selected in the “Select”

section, their value cannot be configured.

9.

The time for starting the logger can be changed using the dropdown in the “Time”

section. This time is used to configure the RTC of the STM8L which is used for time

stamping of logged data.

10. Click the “Write EventLogger” button to configure the boundary values for different

selected sensors.

11. If the GUI shows the error message “Board is not connected”, close the GUI, open it

again and start with step 3 above.

12. If the board is configured for data logging, the “Data Recorded” message is displayed

on the GUI. Click on “OK”.

1.2.14

Event logger stage

This is the logger stage of the system. In this phase the STEVAL-IPR002V1 board logs the

sensor values which are outside the boundary limits configured in pre-event logger stage.

Below are the steps for staring the event logger stage:

1.

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

2.

Insert a 3 V coin cell (CR2032) into the connector, as shown in Figure 5.

3.

Put the switch SW4 into the upward position, as shown in Figure 14, the board is

powered up by the coin cell. This starts the event logger application. The start time is

taken as the time which was configured in the pre-event logger stage.

4.

If a sensor is selected and its value exceeds the boundary limit which is configured in

the pre-event logger stage, then it is logged inside the EEPROM. In the case of tamper,

data is logged only when the tamper switch(SW3) is pressed.

5.

To stop the data logging, put the switch SW4 into the left position, as shown in

Figure 11.

6.

To stop the data logging, put the switch SW4 into the downward position as shown in

Figure 11.

Note:

Once the event logger is stopped using switch SW4 then starting it again through SW4

reinitializes the internal clock reference of the data logger. Therefore, on restarting the data

logger the new start time should be configured using the “Set Event Logger” GUI window.

SW4 is used to connect/disconnect the coin cell from the system.
