Re: NES to USB Keyboard interface?

Unfortunately it's not arduino compatible. You would have to start from scratch to make it work.

Re: NES to USB Keyboard interface?

As promised, here is my approach to interfacing a ps/2 keyboard (and ps/2 mouse) to an NES. A dip switch is used to configure the adapter to either emulate the Family Basic keyboard, or provide full enahnced keyboard and mouse support. More details are in the ReadMe. I have a few more ideas I would ...

I managed to get a ps/2 keyboard interface working via PIC microcontroller, although I still have a few kinks to work out. The biggest issue I'm having is response time. I'm currently holding the keyboard clock line low so all keystrokes are buffered (in the keyboard) until the NES is not reading fr...
