Verified usage

Verified import paths — ran on the pinned version, not inferred.

G29

✓ from g29py.g29 import G29

✗ import g29

Direct import of 'g29' does not exist.

G29FFB

✓ from g29py.ffb import G29FFB

✗ from g29py import G29FFB

G29FFB is in a separate submodule.

Initialize G29, poll data, and print steering wheel angle and throttle position.

import time from g29py.g29 import G29 wheel = G29() if wheel.init(): print('Wheel connected') for _ in range(50): wheel.poll() print(f"Angle: {wheel.get_steering():.2f}, Throttle: {wheel.get_throttle():.2f}") time.sleep(0.05) wheel.close() else: print('Failed to initialize G29')

Debug

Known issues

gotchaOn Linux, you may need root permissions or udev rules to access the HID device. Without proper permissions the init() call will fail silently.

fix

Run script with sudo or add a udev rule (see repository README).

affects: <1.0.0

deprecatedThe function 'get_steering()' returns value in range [-1.0, 1.0] but older documentation mentioned degree angles.

fix

Multiply by the max rotation angle (e.g., 900) to get degrees.

affects: 0.0.12 - 0.0.14

gotchaForce feedback (FFB) requires calling wheel.set_ffb() after each poll cycle, not just once. Many users forget and wonder why no force is felt.

fix

Call wheel.set_ffb(strength) inside the loop after poll().

affects: >=0.0.10

Errors

Common errors & fixes

AttributeError: module 'g29py' has no attribute 'G29'

Wrong import path. The class is in the g29 submodule.

fix

Use 'from g29py.g29 import G29'.

hidapi.HIDException: Failed to open device

Insufficient permissions to access the HID device, or wheel not plugged in.

fix

Run as root/sudo, or add udev rules. Verify wheel is connected and in PS4/PC mode.

OSError: [Errno 16] Device or resource busy

Another process (like a game) is already using the wheel.

fix

Close any program that may have claimed the HID interface.
