# To enable flight logging, define LOGGING_DIR env variable
#
# Env variables:
# LOGGING_DIR      : Full path to directory where flight logs are written to
# LOGGING_MODE     : Trigger event to start logging. Values:
#                      "while-armed" or "always". Default: "while-armed"
# LOGGING_MIN_FREE : Auto-delete old log files until there's at least the
#                    configured amount of bytes free on the storage device.
#                    Set to 0 to disable this functionality. Default: 0 (disabled)
# LOGGING_MAX_FILES: Auto-delete old log files until there are less than
#                    configured amount of logfiles in the log folder.
#                    Set to 0 to disable this functionality. Default: 0 (disabled)
