pypilot reads ~/.pypilot/pypilot.conf for initial settings. This file should not be edited while pypilot is running since it will be overwritten when pypilot is stopped.
~/.pypilot/serial_ports – This is a list of devices pypilot is allowed to use. If the file does not exist, pypilot will try to use any serial port ~/.pypilot/blacklist_serial_ports – This optional file is a list of devices pypilot may not use
pypilot or pypilot/autopilot.py can be run directly from the command line for the best debugging control. In this case the output log will be on the console, and it can be stopped from Ctrl-c
If pypilot is run as a service the output log can be retrieved via journalctl. Under tinypilot, the logs are located in /var/log
