Fsuipc Python [top]

with FSUIPC() as fsuipc: # The offset for parking brake is 0x0BC8 (2-byte value) # Write the value 1 to apply the brake, 0 to release fsuipc.write(0x0BC8, 1, "h")

Using with FSUIPC() as fsuipc: ensures that the connection to FSUIPC is closed properly, preventing crashes.

The most common Python wrapper is fsuipc , which provides a simple interface to the underlying C-based FSUIPC library. Install it via pip on PyPI : pip install fsuipc Use code with caution. Note: This library is designed for Windows platforms. 4. Understanding FSUIPC Offsets

airspeed = fs.read_int(0x02BC) print(f"Airspeed: airspeed knots")

This will install the latest stable version (1.5.0 as of November 2022). fsuipc python

: A Cython-based module designed for Python 3 that interfaces with the FSUIPC user library. How It Works

(Flight Simulator Universal InterProcess Communication) is a popular add-on for Microsoft Flight Simulator (FSX, P3D, MSFS2020) and X-Plane (via XPUIPC). It allows external programs to read and write simulator variables — like aircraft position, controls, instruments, and autopilot settings.

Several Python-based projects allow you to interact with FSUIPC offsets: tjensen/fsuipc : A widely used Python client class wrapper . It is built on top of the original

, preferably a 32-bit version for maximum compatibility with older simulators. On Windows, the package is named fsuipc and is available on the Python Package Index (PyPI). with FSUIPC() as fsuipc: # The offset for

Use a loop with time.sleep() to read data at a manageable rate (e.g., ), rather than maxing out the CPU.

The flight simulation community is full of Python enthusiasts who share code, offsets, and ideas. Whether you are building a home cockpit, logging data for a virtual airline, or just exploring what makes your favourite aircraft tick, the combination of FSUIPC and Python will be a reliable and satisfying foundation for your project.

While not FSUIPC-based, this is a common alternative for MSFS 2020 that connects directly to the SimConnect SDK for similar tasks. Getting Started with fsuipc

while True: line = ser.readline().decode().strip() if line == "GEAR_TOGGLE": # Toggle landing gear (offset 0x0BEC, byte 0 = 1 for up, 0 for down) fs.write(0x0BEC, b'\x01') # Toggle event print("Gear toggled") time.sleep(0.1) Note: This library is designed for Windows platforms

While FSUIPC is built for C/C++, the Python community has created excellent wrappers that make interacting with simulator data as simple as writing a few lines of code. 1. Installation

This is just the beginning. For more advanced control, such as autopilot altitude hold, you'd combine reading and writing in a loop to maintain specific flight parameters. The autopilot and control functions are extensively documented in resources like the "FSUIPC for Programmers Manual".

fs = fsuipc.connect() ser = serial.Serial('COM3', 9600)
