COM Port

This should be the first step before using the Data Logger UI Application.
1. Plug-in the hardware to the PC and check for the COM Port number in
Computer->System Properties->Device Manager->Ports
2. Select the COM Port number in the drop down menu as shown below and Click Open.
Now Software can communicate with Hardware.

1.2.

Log

1. In the drop down menu all the log files present in SD Card are displayed according to the
date. Choose a file that needs to be displayed.
2. As per chosen log file data is displayed either in binary or voltage.
Refer Section 1.3. Data Type for more details.

1.3.

Data Type

1. In the drop down menu choose one among Binary or Voltage.
2. Choosing Binary from drop down menu:
From the log file ADC values are displayed as raw ADC values from 0-1023 (for 10-bit
ADC) and 0 – 65535(for 16-bit ADC).

3. Choosing Voltage from drop down menu:
From the log file ADC values are converted to voltage and displayed in volts.

1.4.

Export to Excel

1. Contents of the log file chosen (in Section 1.2. Log) is exported to PC in .csv file format.

1.5.

Graph

1. Contents of the log file chosen (in Section 1.2. Log) is shown in a Graph.
