# Arduino PS2 Controller Adapter
|
|
## What's This?
|
|
This is a sketch for an Arduino Pro Mini-based adapter that converts DualShock 2 controller signals into XInput! This way, you can use PS2 controllers on any PC without extra software.
|
|
|
|
I also designed a 3D-printable case for the adapter, which you can find [here](https://www.printables.com/model/1291488-arduino-ps2-xinput-adapter)!

|
- [Arduino Pro Mini](https://www.amazon.de/dp/B0CSK6FWSK)
|
|
- Microswitch to reset the Arduino
|
|
- [PS2 controller extension cable](https://www.amazon.de/dp/B07WT6RH72) (you'll need to cut off the female end of this cable to solder its wires to the Arduino)

## Note on Flashing
|
|
Flashing the XInput library makes the Arduino unresponsive to further flashing. In order to flash new sketches, you'll need to manually reset the board. You'll need to perform steps 4-6 on every flash as long as you have the Arduino configured for XInput. Find more information about this [in the readme of the Arduino XInput library](https://github.com/dmadison/ArduinoXInput_AVR?tab=readme-ov-file#upload-warning-and-instructions).
|
|
1. Wire a switch between GND and RST to act as a reset switch
|
|
2. Enable verbose output on upload in `Arduino IDE -> File -> Preferences`
|
|
3. Select the COM port of the board and the corresponding board type as provided by the XInput library. For me, this was `Arduino Leonardo w/ XInput`
|
|
4. Press "Upload"
|
|
5. Once the notification in the bottom right says "Uploading", press the reset switch twice in quick succession
|
|
6. On success, the output window should print out data, concluding with "avrdude done. thank you."
|
|
## Required Libraries
|
|
- [PS2X library](https://github.com/madsci1016/Arduino-PS2X) for interpreting the controller's signals
|
|
- [ArduinoXInput_AVR library](https://github.com/dmadison/ArduinoXInput_AVR) for sending XInput commands via an Arduino Pro Micro
|
|
- [Adafruit_SSD1306 library](https://github.com/adafruit/Adafruit_SSD1306) for display output
