Data logger stage

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

logs all sensor values every one second.

Below are the steps for starting the data 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 data logger application. The start time is

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

4.

All the selected sensor data is logged inside the EEPROM every one second.

5.

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

Figure 11.

Note:

Once the data 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 “Start the Data logger” GUI

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

Note:

Data is logged at an interval of 1 second. Once the memory for a particular sensor is full, no

more data is written inside the EEPROM for that sensor.
