Primitive C64 joystick to Arduino adapter

Pinout

The following pins should be connected.

• Ground (there's one next to digital 13) to Joystick A and B pin 8
• Digital 13 to Joystick A pin 1
• Digital 12 to Joystick A pin 2
• Digital 11 to Joystick A pin 3
• Digital 10 to Joystick A pin 4
• Digital 9 to Joystick B pin 1
• Digital 8 to Joystick B pin 2
• Digital 9 to Joystick B pin 3
• Digital 6 to Joystick B pin 4

Building without Arduino IDE

$ wget https://github.com/dnet/arscons/raw/master/SConstruct
$ scons build

Uploading without Arduino IDE

Default config

$ scons upload

Example for ATmega168-based boards

$ ARDUINO_BOARD=atmega168 scons upload

Dependencies for arscons build process

• Arduino libraries 1.0+ (if you have an older version, rename *.{ino -> pde}, Debian/Ubuntu package: arduino-core)
• Scons (Debian/Ubuntu package: scons)

Known limitations

• it only reads the direction, and ignore fire and other buttons
• it uses pin 13 for input, so there could be problems with boards having an LED connected to it
