Simple Data Logger just became significantly more powerful (and useful): You can now modify the regular expression used to match and capture data. Example: capture and record the net weight sent by a scale and ignore all other data.
SDL receives data sent from a device connected to your computer and writes it to a file. It currently supports devices connected to a COM port (RS-232, USB virtual COM port, Bluetooth SPP) which send data in ASCII format. It can either capture all printable characters (suitable for devices like bar code readers) or the first numeric value it encounters (suitable for measurement instruments like scales and balances). It can optionally add the date and time to the recorded data and transform the decimal separator of numbers from a dot to a comma (if required).
Files written by Simple Data Logger can easily be opened in Excel or other spreadsheet applications.
