An ATARI Joystick driver written in Verilog and Icestudio to use your ATARI like controllers in different projects.

The Atari Joystick is a vey simple controller where each direction is a button, having the following outputs:

• RIGHT
• UP
• DOWN
• LEFT
• FIRE BUTTON

All the buttons are normally closed, that means that the buttons are HIGH without pressing and LOW pressed.

You will need external pull-up resistors to receive the right values from the controller.
