Front-end configuration app for the TempDataLogger project. This script
|
|
configures the logger to the current system time and date, with a user
|
|
defined logging interval.
|
|
|
|
The logging interval should be specified in milliseconds and is rounded to
|
|
a multiple of 500ms.
|
|
|
|
Usage:
|
|
python temp_log_config.py <Log_Interval>
|
|
|
|
Example:
|
|
python temp_log_config.py 500
|
|
|
|
Requires the pywinusb library (https://pypi.python.org/pypi/pywinusb/).
