# A script to start up controls and icsim (ICSim by Craig Smith
# https://github.com/zombieCraig/ICSim)
# along with cansniffer (can-utils project at

# If you used my can_stuff_install.sh script then there is nothing to do.
#
# If you installed them on your own and changed the git repository,
# set the ICSIMDIR to the directory installed ICSim,
# with trailing slash (see config section).
#
# tested on Ubuntu 14.04 LTS amd64
#==============================================================================

#==== config ==================================================================

# change if you changed the git repository for ICSim or changed icsim_install.sh
ICSIMDIR='/usr/share/ICSim/'

# turn on off seed logging
LOGSEEDS=true

# the full path file you wish to log the seeds
SEEDSLOGFILE='/var/log/icsim_seeds.log'
