For some projects, a circuit making it possible to connect 12 buttons including 4 directional buttons to a PC using an USB port is very useful. Here’s a few examples: Home-made Arcade style controller and small arcade cabinets Simple controller 1 wire per button to Datqsheet.

Using appropriate software on the PC side, the inputs can be used for other purposes.

A cleaner solution than modifying an existing game controller On this page, you’ll find out how to build such a circuit using a microcontroller. The firmware implements a standard USB joystick with 4 directional buttons and 8 general purpose buttons.

Depending on your skills, you can build the circuit on a breadboard using thru-hole components or build the surface-mount version using my small multiuse PCB2 circuit board.

I also sell ready to use circuits and pre-programmed Atmega8 chips in DIP package only. Visit my online shop for more details. That’s right, since the USB standard defines device classes. I’m using the human input device HID which allows me to tell to the computer that the connected USB device is a joystick and has 2 axis and 4 or 8 buttons.

Another nice thing about this is that the adapter should work with all operating systems supporting HID devices. This microcontroller does not support USB in hardware so I used the software-only usb driver from Objective Development.

As a result, the interface can be built cheaply and easily Ready to use circuits available. Here is the main schematic: And here is a wiring example: Additionally, a wiring table for NeoGeo controllers is shown lower on this page. Ref Datashret U2 Atmega8 microcontroller. R2, R3 68 ohm resistors.

R4 Do not install, not used anymore. D1 Do not install, not used anymore. Y1 12 Mhz crystal.

C2, C3 27 pf capacitors. If the crystal datasheet recommends another value, use it instead. Install it near the ATmega8. You can also use dip switches, ordinary switchs or solder bridges.

J2 6 pin header, 2. Needed for programming the ATmega8. USB uses standard wire colors: A microcontroller is a component which must be programmed in order to do something useful.

So here is the hexfile which must be atmega816pi into the microcontroller: In the case of the ATmega8a, there are two bytes: The high byte, and the low byte. Those bytes are used to configure some aspects of the microcontroller.


What type of clock to use? Allow programming via ISP? It’s very important to set the fuses to the right values. Using the wrong values can render your MCU unusable. For this project, here are the appropriate fuse values: Pre-programmed Atmega8 DIP package available. The source code is released under the GPL license and compiles with avr-gcc. To request features, report issues or contribute, you may send me an email or use the GitHub repository: The surface-mount version uses my Multiuse PCB2 circuit.

Here’s what it looks like: Wiring diagram for this project on ‘Multiuse PCB2’: Ready to use circuits available. Neo Geo controllers uses standard DB15 connectors.

This connector is also used by old PC Joysticks but it incompatible.

Here’s a table describing how to wire a Neo Geo controller connector to this circuit: Please note, however, that the procedures above have worked in my case ratasheet any damages or problems.
