If the stick doesn't return to <code>0.00</code>, it flags a centering error.</li> <li> <strong>Polling Rate Check:</strong> By measuring the time between <code>gamepadconnected</code> events and input updates, we can estimate the Bluetooth latency (Hz).</li> </ol> <p><strong>How to use it</strong><br> You can test your controller here: <a href="https://testmygamepad.com/calibration.html" rel="noopener noreferrer">Calibration Tool</a></p> <p>It supports:</p> <ul> <li>DualSense (PS5)</li> <li>Xbox Series X|S</li> <li>Joy-Cons (Nintendo)</li> </ul> <p>I'm also working on a documentation hub for hardware repairs.</p> <p>Let me know if you have any feedback on the input visualization!</p> javascript webdev showdev gaming
