this is my instructable see to more information.
What you can do with it :
transmit data between arduino and ndsl.
so, you can use your ndsl to arduino's wireless lan or arduino to your ndsl's digital IO port!
What you need:
NDSL GBA cart cover
nintendo Y driver (eventhough you don`t have, no problem!)
some wires (3 wires, enough! 4 wires GREAT)
libnds (for nintendo development)
How it works:
NDSL has GBA bus. It has /WR pin and External interrupt pin.
If you access gba bus, /WR will toggled, so I can use /WR to send data.
However, it lasts just 350us. It mean you cannot use this pin to digital I/O pin directly.
So I mimic NEC REMOTE CONTROLLER protocol(TV, VIDEO etc...)
External interrupt pin is used to receive data, /WR pin is used to send data.
ARDUINO works exactly same way.
these are my youtube video
this is my source code(library + example)
I tested it only with my NDSL and ARDUINO, so it could have some errors.
If you have any question or find problem, send me mail
