# Uncomment to make node autostart after X time-msgs has been sent to node
# Do not choose 0 as X, also 1 is a bad choice
# This should not be used on nodes with application under developement
AUTOSTART=2

# Node hardware id, this number should be unique on your network
# leave as <GENERATE_HW> at first compile, the build will then automatically set it to whatever gets generated (see config.h)
# Never set this manually if you are not sure what you are doing

#NODE_HW_ID=0x12345678 

# F_CPU is the clock frequency of your microcontroller, check fuses below for external/internal clock source
