Got it working. Windowa didn’t recognize it until I changed the 27pF capacitors to 22pF as stated in the atmega8A datasheet.

works great now!

Sorry =)….yes, it works well under Win7

It’s supposed to work since a standard USB HID device will be emulated. Although I didn’t test under Win7, don’t have the OS.

Hello. I would like to ask if this device can work with operating system Windows 7. Thank you

About the diodes you have to try, don’t know for the moment.

You can remove parts of the code, might give some improvement but I wouldn’t expect much.

Hi,

I am going to build an Arcade Stick used mainly for Fighting – and Arcade Games.

The stick I ordered has one mass for all four directions.
If I just put the diodes on the other side of the switches will they still prevent ghost keying?
(They should, right?)

I took a short look at the code and it seems to me all buttons are enabled by default.
Considering the performance (some arcade games are pretty delay sensitive) would it be an improvement if I throw out all of the stuff I don’t need or isn’t it nessesary? (no need for analog controls)

Despire studying Electical Engeneering I really prefer asking before I order too much stuff and went into trouble.

Thanks Lothar

Hello,

My name is Alfonso and I am working with a PS3 controller. I want to do a modding with the pad but I have a problem, I can’t use the home button, it doesn’t work. So, there is any way to emulate this button with this AVR Joystick?

Thanks

Yes, will work.

Does this ATmega8 works for this circuit?

Dan, this is a late reply so you may have already worked it out, but just in case anyone else needs the information here it is – you shouldn’t need to use a 7805 voltage regular as long as you use 3.6v zener diodes and remove the 4.7k resistor. When I suggested trying a 7805 that was only for testing purposes because the original design used an incorrect method to drop the voltage on the Data lines. It will work using power from the USB, no external power should be required.

Now considering the 7805 is not necessary anymore, the only reason I can guess as to why it would only run from a battery is that your wall wort was not at least 7.5v or higher, as most standard 7805′s need at minimum 1.5v higher voltage than what it will output (5v).

Once again for clarity, you need to do both of the following:
-Use 3.6v zener diodes
-Remove 4.7k resistor
