OutSim

See also: OutGauge

OutSim is a protocol which allows motion simulator support in LFS. More information can be found in the file LFS\doc\InSim.txt and LFS\doc\OutSimPack.txt.

Configuration

To instruct LFS to send OutSim packets, update this section of your LFS\cfg.txt file:

// OutSim Mode 0        :0-off 1-driving 2-driving+replay
// OutSim Delay 1       :minimum delay between packets (100ths of a sec)
// OutSim IP 0.0.0.0    :IP address to send the UDP packet
// OutSim Port 0        :IP port
// OutSim ID 0          :if not zero, adds an identifier to the packet

Example

Here is an example of receiving OutSim packets using Python.

import socket
import struct

# Create UDP socket.
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

# Bind to LFS.
sock.bind(('127.0.0.1', 30000))

while True:
    # Receive data.
    data = sock.recv(256)

    if not data:
        break # Lost connection
  
    # Unpack the data.
    outsim_pack = struct.unpack('I12f3i', data)
    time = outsim_pack[0]
    angvel = [outsim_pack[1], outsim_pack[2], outsim_pack[3]]
    header = outsim_pack[4]
    pitch = outsim_pack[5]
    roll = outsim_pack[6]
    accel = [outsim_pack[7], outsim_pack[8], outsim_pack[9]]
    vel = [outsim_pack[10], outsim_pack[11], outsim_pack[12]]
    pos = [outsim_pack[13], outsim_pack[14], outsim_pack[15]]

# Release the socket.
sock.close()
