Coding > GBA to communicate with PC?

#23228 - analogbinary - Wed Jul 07, 2004 11:36 pm

Hi, Im new to this forum, and im not sure if this is the correct place, but it seemed the most sensible..

Basically, I need to be able to communicate with a PC from a GBA. I need to simply send a string from the GBA to the PC.

Idea:-

I will make a small mp3 player in my car (pc), and use the GBA as a starting point for the *controller*, so the playlists etc will be listed on the GBA (i can compile and makes the menus etc), im very unsure about how i can talk back to the PC however. Is it posible over the USB linker cable? or do i need to make my own serial connection up? Any help would be appreciated!

Thanks!

Search for GBA to PC. It's been discussed a few time recently.

Thanks, but the search on this forum seems to return about 100 unrelated posts for various combinations :S

Just for some hope, is it possibe to use the linker usb cable to communicate? (surly the linker software can send, and it knows when the GBA state changes start+select etc?). Or is a serial to Rs232 better?

Is there any code prewritten. I know some C (probably intermediate), and i did 68k ASM for a bit at college, so im not going to be able to jump in at the deep end without being able to hack at some source code.

The pc end isnt a problem, i can write the software to do pretty much anything, its the GBA end im going to get stuck on.

Cheers!

I don't know about USB, but a few people here have got RS232 working fine. Anyone want to post some example code links?

Problem with USB linkers is that there is no documentation on most of them. RS232 is the easiest. The Xboo cable also work, but is a little more tricky.

Hi,

Cheers for the info guys!

i now know i need to either build a rs232 cable with voltage changing etc, or get one of those handy cables (they have rs232/par on one end), they are about ?10?

Thanks again.

Hi.

Did you have any success with this linking a GBA to a PC through serial port? This is exactly why I'm lurking in this forum now. Any information you could share would be much appreciated.
