Why Use MMJoy2?

• DirectInput: It emulates a standard DirectX joystick, meaning it works with almost all flight sims (DCS World, MSFS 2020, IL-2) without special drivers.
• Customization: You can map axes, buttons, and encoders entirely through the GUI.
• Cost: It is a cost-effective way to build custom simpit hardware.

Flash the Firmware: Connect your Arduino, put it into bootloader mode (usually by shorting the RST and GND pins), and use the JoySetup.exe tool to upload the MMJoy2 firmware. Flash the Firmware: Connect your Arduino, put it

Massive Input Support: Supports up to 8 axes and 128 buttons on a single controller.
