It can be # given read, periodic read and write, requests, that are executed # asynchronously, and a callback function is called with the result. This class # is used internally within the module. # # The \ref Simulator class is the actual interface to the flight simulator, and # an instance of it is returned by \ref mlx.fs.createSimulator. This object can # be used to connect to the simulator and disconnect from it, to query various # data and to start and stop the monitoring of the data. # # \ref AircraftModel is the base class of the aircraft models. A "model" is a # particular implementation of an aircraft, such as the PMDG Boeing 737NG in # Flight Simulator 2004. Since each type and each model has its peculiarities # (e.g. the different engine and fuel tank configurations), each aircraft type # has a generic model, that should work for most of the time. However, certain # models may implement various controls, gauges, etc. differently, and such # peculiarites can be handled in a specific subclass of \ref # AircraftModel. These subclasses should be registered as special ones, and if # the simulator detects that the aircraft's model became known or has changed, # it will check these special models before resorting to the generic ones. # # The models are responsible also for querying certain parameters, such as the # fuel tank configuration. While ideally it should be specific to a type only, # it is possible that the model contains different tanks, in which case some # tricks may be needed. See the \ref DC3Model "DC-3 (Li-2)" aircraft as an # example. #------------------------------------------------------------------------------ ## The mapping of tank types to FSUIPC offsets _tank2offset = { const.FUELTANK_CENTRE : 0x0b74, const.FUELTANK_LEFT : 0x0b7c, const.FUELTANK_RIGHT : 0x0b94, const.FUELTANK_LEFT_AUX : 0x0b84, const.FUELTANK_RIGHT_AUX : 0x0b9c, const.FUELTANK_LEFT_TIP : 0x0b8c, const.FUELTANK_RIGHT_TIP : 0x0ba4, const.FUELTANK_EXTERNAL1 : 0x1254, const.FUELTANK_EXTERNAL2 : 0x125c, const.FUELTANK_CENTRE2 : 0x1244 } #------------------------------------------------------------------------------ class Handler(threading.Thread): """The thread to handle the FSUIPC requests.""" @staticmethod def fsuipc2VS(data): """Convert the given vertical speed data read from FSUIPC into feet/min.""" return data*60.0/const.FEETTOMETRES/256.0 @staticmethod def fsuipc2radioAltitude(data): """Convert the given radio altitude data read from FSUIPC into feet.""" return data/const.FEETTOMETRES/65536.0 @staticmethod def fsuipc2Degrees(data): """Convert the given data into degrees.""" return data * 360.0 / 65536.0 / 65536.0 @staticmethod def fsuipc2PositiveDegrees(data): """Convert the given data into positive degrees.""" degrees = Handler.fsuipc2Degrees(data) if degrees<0.0: degrees += 360.0 return degrees @staticmethod def fsuipc2IAS(data): """Convert the given data into indicated airspeed.""" return data / 128.0 @staticmethod def _callSafe(fun): """Call the given function and swallow any exceptions.""" try: return fun() except Exception, e: print >> sys.stderr, util.utf2unicode(str(e)) return None # The number of times a read is attempted NUM_READATTEMPTS = 3 # The number of connection attempts NUM_CONNECTATTEMPTS = 3 # The interval between successive connect attempts CONNECT_INTERVAL = 0.25 @staticmethod def _performRead(data, callback, extra, validator): """Perform a read request.
