HANtune has the option to write and read data received from target communication into a log file. The logged parameter values are written into a .csv file.
To start recording signals, enable it by going to “Communication -> Enable Datalogging” or click on the log file button at the bottom status bar.
The name of the log file can partially be changed by going to “Communication -> Modify Datalog Filename”.
The current date and time will automatically be appended to the filename each time a new logging is started.
The log file will be saved (default) in the “log” subfolder folder in the HANtune folder. If desired, this folder can be changed by going to "Preferences -> User Preferences". Type or browse your desired folder in the "Log Location" field.
Log File Contents
A log file consists of two parts: a header and log values. Both are in human readable format. The header contains additional information as:
Next to the header, the actual log values are written into the file. Each line starts with a timestamp (in Seconds), followed by all the values of the signals received at that time. Each signal value is separated by a semicolon (;). A dot (.) or a comma (,) (depending on your language settings) denotes a decimal separator. A thousands separator is not used.
Using a spreadsheet capable of reading .csv format, you can examine a log file.
