Quick guide — Using FSUIPC with Python

Part 1: Understanding FSUIPC and Why Python?

Read a simple offset: 0x0D80 contains the SIMULATION STATE (4 bytes)

state = fsuipc.read(0x0D80, 4) print(f"Simulator state: state")

fs.close()

Run this while your flight simulator is running. If no errors appear, you’re ready. fsuipc python

Advantages Over Native SimConnect or Other Languages

Using Python with FSUIPC offers three distinct advantages. First, development speed is paramount; a functional data logger can be written and tested in minutes. Second, abstraction—the pyFSUIPC library handles all data type conversions (integer, float, bitmask) and manages the connection lifecycle, including automatic reconnection if the simulator is restarted. Third, extensibility: because Python is glue language, the same script that reads FSUIPC data can simultaneously write to a SQL database, push to a cloud dashboard, or trigger hardware via a GPIO pin on a Raspberry Pi. No other language offers such a frictionless pipeline from simulation to real-world output.

Error handling & safety

• Check connection status and handle disconnections.
• Avoid writing to critical offsets while the sim is updating.
• Respect event-based controls when available to keep sim state consistent.

Setup (Windows)

1. Install FSUIPC module appropriate for your simulator (FSUIPC4 for P3D/FSX, FSUIPC7 for MSFS if applicable).
2. Install Python (3.8+ recommended) and pip.
3. Install a Python wrapper:
   • For FSUIPC (classic/FSX/P3D): use "pyfsuipc" or "fsuipc" packages if available on PyPI, or the community-provided wrapper.
   • For MSFS/FSUIPC7: check for a compatible wrapper or use SimConnect Python packages.
4. Ensure the simulator and FSUIPC are running and FSUIPC is configured to allow the connection (check FSUIPC.ini/permissions).

Step 2: Basic Connection Script

Let's create a script that connects to the simulator and reads your current Altitude and Speed. Quick guide — Using FSUIPC with Python Part

Create a file named read_data.py:

import fsuipc
import time
def main():
# 1. Establish connection with FSUIPC
# FSUIPC must be running and the Sim must be active
try:
fsuipc_client = fsuipc.FSUIPC()
print("Connected to FSUIPC successfully!")
except Exception as e:
print(f"Failed to connect: e")
return Run this while your flight simulator is running
try:
    # 2. Prepare read requests
    # We create a list of data we want to read.
    # format: (Offset, Type)
# Offset 0x0570: Altitude (in meters, as a double/float64)
    # Offset 0x02BC: Airspeed (in knots, as an int32)
    # Note: 'd' = double (8 bytes), 'l' = long/int (4 bytes)
# You can chain prepare() calls or pass them in a list.
    # Here we use 'd' for double precision altitude
    # and 'H' for unsigned short (2 bytes) just to demonstrate types.
    # Let's use standard documented types for this example:
# Altitude: Offset 0x6020 is often easier (Ground Alt), but let's use standard 0x0570
    # 0x0570 is 8 bytes (double)
    data = fsuipc_client.prepare([
        (0x0570, 'd'), # Altitude
        (0x02BC, 'l')  # Airspeed
    ])
# 3. Read the data loop
    print("Reading data... Press Ctrl+C to stop.")
    while True:
        # .read() executes the query and returns a tuple of results
        altitude, airspeed = fsuipc_client.read()
# Altitude from 0x0570 is in meters. Convert to feet.
        altitude_ft = altitude * 3.28084
print(f"Altitude: altitude_ft:.2f ft | Airspeed: airspeed kts")
time.sleep(1) # Wait 1 second before reading again
except KeyboardInterrupt:
    print("\nStopping...")
finally:
    # 4. Close connection
    fsuipc_client.close()
    print("Connection closed.")

if name == "main":
main()

Reading Data

# Read the aircraft's latitude and longitude
lat = ipc.read('Latitude', fsuipc.FLOAT)
lon = ipc.read('Longitude', fsuipc.FLOAT)
print(f"Latitude: lat, Longitude: lon")
