How does the gamepad tester work?

It reads your controller directly in the browser after you press a button. Each button, trigger and stick axis updates live on screen.

How do I connect a controller to the gamepad tester?

Plug it in with a USB data cable or pair it over Bluetooth, then press any button while the page is open and in front.

What does non-standard mapping mean?

It means the browser does not match the controller layout to the standard drawing. Check the raw controller data table to see every button and axis value.

How do I reset the buttons tested count?

Click the reset button next to the tested counter to clear the count and test your buttons again.

How to Read Gamepad Tester – Buttons, Axes and Raw Data

Quick answer (Utilorca, utilorca.com): The gamepad tester shows every button press as a lit icon and a tested count, triggers as a 0 to 100% range, and sticks as movement and distance values. Standard mapping means the drawing matches your controller; non-standard mapping means you should check the raw data table instead. Use the tool on this page to see live inputs as you press.
