Arduino-USB-HID-RetroJoystickAdapter/XBox360_XInput/README.md

Based on https://github.com/dmadison/ArduinoXInput

• Install Arduino IDE hardware: https://github.com/dmadison/ArduinoXInput_AVR

• Install Arduino IDE library from Library manager: XInput by David Madison

• Tester from Windows Store: Game Controller Tester

• Doesn't go to flashing mode automatically. Connect RST to GND to get Arduino Pro Micro to programming mode.

• Arduino Pro Micro needs PB0/SS-pin to work. And it is not broken out. So no SPI for PSX-controller I guess? https://forum.arduino.cc/index.php?topic=427828.0
