Hello,

Could anybody send me a template for the GBA cartridge PCB?
A Protel 99 pcb template would be great, but even a mechanical drawing
will help a lot.

thanks,
Vital

Hello all,

      I wonder if there exists a kind of GUI toolkit
ofr gameboy. With this toolkit I mean something a la
GTK, QT or even TCL/TK.

I already found WinS or something, but do there exist
more?

Kind regards,

Jan

Indeed, you'll need to build it. It would be nice if the various
flashrom usb programmers
could double as serial ports.

I recently built a USB<->GBA cable based on Darkfader's design. I
also built a little
program to communicate between Macromedia Director <> GBA which is
buggy but will
get you there. I'll be rewriting the communication protocol in the
next couple of months using interrupts, probably when I've finished with the
MIDI project.

You can follow this link at:

http://hypermedia.loeil.org/playmobile/user/douglas/

and scroll down to the entry "usb+ttl+gba" where you'll find an image
of this project. Instead of going serial <> max232 <> GBA, I decided
to use the
well-known FTDI USB<>TTL chip.

There are lots of links and some code (cf. "download"). Its all in
French, but you should be
able to figure it out. Drop me a line if you're lost.

You can see the one I just made if you follow
the link at the bottom of this page:

http://www.msh-tools.com/GBA/gbagps.html

there you will see my very rough assembly,
including the embedded antenna (to Hari Nair:
that's what they call it - it's an antenna you
can embed!).

I turned it into a more successful project
by using my old original GBA, which doesn't
mask the module.

Unfortunately I can't help on the buying
side. I just phoned the local distributor
here in the uk and I had it next day.

I have sent three emails to the Trimble's sales manager, Brad Lynch,

Please let me know how it works out - I have used the SQ module
externally connected to the link port in uart mode with the trimble
compact patch antenna. I found that I could not get an initial fix on
moving cold start. It took several minutes for initial fix on
stationary cold start, and after that was Ok. I did not implement warm
start functionality, so do not know how that improves the situation.

check out www.pixelproc.net - gives idea of the rough dimensions of the
sq module and the patch antenna relative to the GBA SP dimensions

Hari

Hello,

I am looking for a RS232 cable that can connect the gameboy advance serial
port to a PC RS232 port. I think that the voltages must be converted from
0 - +3V to something like -5V - +5V. Does anyone know where a can buy such a
cable with level shifter?

Any help will be greatly appreciated.

Yes. I was hestitating over this. I was aiming
for a really-simply-system®, so that people off
the web could just hack open a midi cable and
plug it into the GBA without a PIC. But even with
a couple of resistors and whatnot we're already
talking about soldering, i.e. for
people-in-the-know, so I might as well go with a
PIC solution: cleaner, easier to program (just
use the 38400 UART mode and let the PIC do all
the work).

Yes. I was just going through the skimpy docs
on-line on interrupts just for this purpose. I
think I've got it down now.

Not everyone has access to some sort of external
programmable circuit. I'll see with my time-frame
what's the easiest. Thanx for the info.

Thanks for the information. I will use the Lassen iQ module, that
consumes a little less power than the SQ and will use an external
antenna. I was looking for a module with an integrated antenna but,
as you told, the metal shield would cause problems. Anyway, I would
need an external antenna for use in vehicles.

The Lassen iQ seens to be easy to buy samples.
The only thing that would be better than the Lassen iQ would be a
module with a SPI interface. It would save me of implementing an UART
in my CPLD.

thank you
Vital

There are a few things that will need to be addressed when connecting a midi
system to the GBA...
The first issue I see is the voltage difference - midi is a 5V interface
whereas the GBA comm system is 3V.  While this isn't necessarily a problem
(as the nocash xboot cable works fine), it could potentially hurt the GBA's
comm system.
As far as whether the communications should be handled in software or
hardware, the only difference is what kind of a challenge the implementation
is.  An external hardware system that buffers and retransmits data is
relatively simple to create, and much less of a pain to code for. It is also
possible to do the communicaitions on the gba itself. When in general
purpose comms mode, the GBA can be instructed to interrupt when SI
transitions from high to low, which will detect the beginning of an incoming
UART transmission.  After that, at 31250bps, the gba has approximately 537
cycles per bit to deal with incoming data, so many means of collecting the
data (timer interrupts, or just wait loops) could be used.

In my opinion it doesn't really make much difference whether the
transmission and receiving is done in hardware or software... hardware has
the potential to be a bit more stable, but software won't require as much
external work.

I'm trying to get MIDI into the GBA through the
serial interface. I've done lots of experimenting
with this serial port (cf.

but getting MIDI in looks like it's going to be a

this? (I already know of all the GBC MIDI
projects -- pushpin & firestarter -- I'm
interested in a GBA-specific solution).

The main problem is that MIDI working at 31250
baud whereas the GBA supports only 9600, 38400,
57600, and 115200.

I was thinking of using the serial port in
General-Purpose mode, and trying to figure out
all the timing. This is cleaner than building a
PIC-based MIDI->UART converter, but I don't
really have any experience with General-Purpose
so I wanted to get someone's (anyone's?) opinion
on this matter before getting my hands dirty.

The Trimble Lassen SQ (or newer IQ model) does not have an embedded

Hey, has anybody done any RTC programming with an EFA cart?  If so how
and what did you do? Does anybody out there know where I could get
some info on this? EFA's website has no info.  If I want to get the
RTC data from a memaddress, does it even matter which cart I use, do
various flash carts have this in different places or same places?

Any info would be great, Thanks!

The only way to get to use one without having official developer status is
join a Nintendo approved games programmning course as far as I'm aware..

I recently put a Trimble Lassen SQ module onto
to link socket of a Gameboy DS.

I found that when the screen was folded right
back it masked the signal from the embedded antenna.

So... where is your antenna going to be? The cartridge
slot is shielded with a metal screen on at least one
of the GBA's.

Hey, I'm thinking about making a clock for GBA that would display FF
XI Vana'diel time (Ferry, Airship, Guild schedules, etc.) Anybody
out there interested in somethin like this? Does anybody out there
know of any good time libraries (prefereably to work with HAM, that
has funcs like one that will give me the difference of two dates in
seconds, etc?

Thanks

Travis Brown

So what the price and does it come with serial number etc.

I know of Trimble Lassen SQ module. The current part is 12 channel,
3.3V, serial interface, NMEA ASCII or proprietary binary protocol. You
can contact Trimble directly for purchasing samples.

Jason,

Thanks for the information. This module is almost what I am looking
for, except for the supply voltage. If I do not find a 3V module, I
can use a charge pump to produce the +5V.

Might be just what you are looking for.  A friend just

Hello,

I am looking for a "very" small GPS module to include in a GBA
cartridge. So far, the smallest module I have found is the FS Oncore,
from Motorola
(http://www.motorola.com/ies/GPS/products_positioning.html), but
there may be other options that I do not know. I still do not know if
it is possible to buy the Motorola's module in fairly low quantities.
I would like to find a module that requires only 3V and low power and
has serial or SPI interface.

Any help will be greatly appreciated.

thanks,
Vital

Yeah they accept composite inputs so there shouldn't be a problem.
