Running SITL: There are several options for running SITL. In all cases, SITL will output a mavlink stream on 127.0.0.1:14550 (UDP) for connection to any GCS software (Such as Mission Planner). An EEPROM (containing the state of the APM's flash memory - paramters, waypoints, etc) is saved for each vehicle type and (by default) will be re-loaded each time SITL is run. This can be overidden to start with a new EEPROM containing all default values. To continue with the current EEPROM, run: RunCopter.bat for a quadcopter running APM:Copter RunPlane.bat for running APM:Plane RunRover.bat for running APM:Rover 4) Updating the APM source code To update the APM code with the latest of Github, run UpdateAPMSource.bat. Note this is bleeding-edge source code and some bugs may be present. Deleting the SITL environment To uninstall/delete the SITL environment, simply delete the "cygwin64" folder in the C:\ drive.
