ok, im not a "newbie" in hardware debelopment... just new in GBA development...

i want to know i can make a simple robot comtrolled by the gba...
without having to buy a robot like xport...
if yes...can someone point me some kind of guide or sheme..

also i want to know if is posible that someone make a multiboot guide of what its need because i have seen many but dont understand them...

and last but not least......if i made a chip ... how i can make a "driver" to program it?
and is posible to make a flascart and flahs linker without having to buy one
because the problems is i live in dominican republic and cannot order anithing

sorry my bad english and thanks for your help

For comms between the GBA and other HW, you'll need something that can handle UART protocol at between 9600 and 115200 bps and at 3.3 volts.

There aren;t too many options for communication between your robot and the gba.

1. Use COMMS mode as tepples has suggested.

2. Make all your robot control IO, memory mapped and put decode logic on a flash cartridge.

Ampz has a flash cart design about. Do a search on the forums for this.

The link port can be used as general purpose I/O, so as long as you only need 4 I/O pins, this is the easiest way.

Atmel AVR Processors should do the job for you. They are cheap, have ADCs (analog-to-digital converter). All have UART, and they should all be able to run at 3.3V. Also, you can interface them with lots and lots of stuff....
