SDL3 Input Tester

SDL3 Input Tester is a desktop app built with .NET and Avalonia to inspect and test joystick devices on Windows.

Its main purpose is to act as a practical button and axis tester for SDL3 joystick-compatible devices, including:

• Joysticks
• Flight sticks
• Steering wheels
• Other joystick-class controllers supported by SDL3

What it does

• Detects connected SDL3 joystick devices
• Lets you pick a device and open a live test view
• Shows real-time button states
• Shows real-time axis values and movement bars

Why this project exists

I built this app to have a straightforward way to validate hardware inputs while testing controllers and peripherals.

Contributions

I accept PRs with:

• New features
• Bug fixes

That said, for my current needs I consider the application functionally complete.
