IceBreaker - V2.0 "Polaris"

A sleek and easy-to-use focused release of Robert Franke's icebreaker with enhanced analysis support.

Changelog

• Removed inclination detector support
• Removed server
• Fixed average.py
• all paths used for the analysis scripts are now found in analysis/config.sh, which defines the paths as variables and thus might need to be sourced
• However, it is still needed to check the paths in icebreaker.py and barometer.py
• fixed the generation of the status webpage
• reworked the analysis.sh script. It is now more sleek and easier to read. Unused features have been removed
• don't fail if the barometer does not work

Files and directories

data dir: A single dir for the rawdata and pre-analyzed data is recommended - structured like this:

rawdata (datadir) |_ analysis |_ daq |_ pressure

Crontab

analysis/analysis.sh and analysis/send_report.sh need crontab entries to be executed each day

if data should be back-up'd another crontab entry is recommended

Setup

icebreaker.py and barometer.py both have to run via the python daemon library. To do so, the service architecture of ubuntu is invoked

You can start services with: sudo service daq start

That this works, the script "daq" has to be in the /etc/init.d/ folders. This is taken care of by icebreaker/daq/setup_boot.sh and similar for the barometer by icebreaker/barometer/setup_boot.sh

A temporary folder needs to exist and has to be given in analysis/config.sh
