Eddie's Tech Notes

Items needed Arduino Leonardo (or equivalent). Note that it has to have at least one 3.3V power output. A standard PlayStation 1 controller A Densha de Go controller 6 male-to-female jumper cables Procedure Initial Cabling Using the jumper cable, connect the typical PlayStation 1 controller with the Arduino Leonardo. PlayStation 1 controller pin numbers --------------------- \ 1 2 3 4 5 6 7 8 9 /  ------------------- Connection to Arduino Leonardo * PlayStation 1 controller pin 1 (DATA) --> Arduino Leonardo digital port 12  * PlayStation 1 controller pin 2 (CMD) --> Arduino Leonardo digital port 11  * PlayStation 1 controller pin 4 (GND) --> Arduino Leonardo port GND  * PlayStation 1 controller pin 5 (VCC) --> Arduino Leonardo port 3.3V  * PlayStation 1 controller pin 6 (ATT) --> Arduino Leonardo digital port 5  * PlayStation 1 controller pin 7 (CLK) --> Arduino Leonardo digital port 4 Set up Arduino IDE Install the IDE is available at  https://www.arduino.

This article discusses how we could use PlayStation 1 Densha de Go! controller in emulators, using Retropie as an illustration. In short, the controller is pressing multiple opposite directions simultaneously and we need to register the d-pad as buttons not axes in order for the controller output to be read.   Items needed Standard Raspberry Pi equipment: a Raspberry Pi board, power source and cable, HDMI-capable monitor and HDMI cable, a compatible micro SD card, a USB keyboard and a USB mouse, a USB controller.  A PlayStation 1 typical controller A PlayStation 1 Densha de Go! controller Your favorite PlayStation 1 Densha de Go! game, copied as disk image Some male-to-female jump wires A breadboard Steps Basic Retropie setup Proceed typical Retropie installation routine on the Raspberry Pi. Insert the disk image of the Densha de Go! game into the Raspberry Pi, under  /home/pi/RetroPie/roms/psx by default. Make sure you know how to access to the Retropie con
