Error from PyCapsule

[Matthewli623]

1. After Installing the fsuipc by "pip install fsuipc" , I tried to run below script and i got the below error.

C:\Users\user\Documents\GitHub\PythonPlayground>C:/Users/user/AppData/Local/Programs/Python/Python37-32/python.exe c:/Users/user/Documents/GitHub/PythonPlayground/testbat.py Traceback (most recent call last): File "c:/Users/user/Documents/GitHub/PythonPlayground/testbat.py", line 27, in latitude, longitude, altitude = prepared.read() AttributeError: 'PyCapsule' object has no attribute 'read'

from fsuipc import FSUIPC
with FSUIPC() as fsuipc:
    prepared = fsuipc.prepare_data([
        (0x560, "l"),
        (0x568, "l"),
        (0x570, "l")
    ], True)

    while True:
        latitude, longitude, altitude = prepared.read()

        print(f"Latitude: {latitude}")
        print(f"Longitude: {longitude}")
        print(f"Altitude: {altitude}")

        input("Press ENTER to read again")

2. Apart from download it from github , I have downloaded fsuipcSDK .I am able to use it but it is a bit slow which take 200 ms to read or write data.Is there any way to improve the speed?

Thank you!

Hi @Matthewli623. The version you downloaded from PyPI was an alpha release, which had a different interface from what is currently shown in the README on GitHub.

Good news, however! I just published version 1.0.0, which should enable you to run the example code. Please upgrade your installation by running the command:

pip install -U fsuipc

Regarding your question about the performance, I'm seeing individual read calls take about 4 or 5 ms to complete when I run the following code against Flight Simulator X:

import timeit

from fsuipc import FSUIPC

NUM_READS = 1000

with FSUIPC() as fsuipc:
    prepared = fsuipc.prepare_data([
        (0x560, "l"),
        (0x568, "l"),
        (0x570, "l")
    ], True)

    duration = timeit.timeit(prepared.read, number=NUM_READS)

    print(f"Duration: {duration} seconds ({duration / NUM_READS} seconds per read)")

Can you share the code you are running to get the 200 ms measurement? Also, I'm wondering if other simulator versions may give very different results.

Hi @Matthewli623. One week has passed without any activity, so I am assuming that upgrading fsuipc has fixed your issue and that you no longer need assistance. Thanks.
