He probably would want to use UART mode.  The only issue would be
making sure the voltages match up.

He could do it general purpose mode, but it requires way too much CPU
time.  The UART mode could trigger an interrupt when something was
ready to be read.

Mike,

  I found this website to be very helpful.
http://www.robmeerman.co.uk/project.  Download the report disc content, and
look for the source code for the serial interface.  It tells you how to put
the serial port into multi-purpose mode, and set each of the 4 digital lines
to the values you want.  You'll need to write a function that reads the
states of the digital lines.

I am very new to GBA programming, but would like to build an
application that links a GBA to a Garmin GPS that I have.

I have found a couple of sites that present this type of application,
but none of them share the C code segments required for the GBA to
receive the NMEA packets into variables in the code.

Can anyone help me with some example code?

Thanks in advance for any help...

Mike

Thanks for all who replied.

I remembered that I had the book "MicroC/OS-II", so I selected
uC/OS-II, from Micrium. My application is not commercial (so far), so
I can use the version that comes with the book.

I tried to use eCos but it almost drove me crazy to configure those
endless parameters. It is not for mere mortals, even the Charmed Labs
version.

Maybe he doesn't need to.  Maybe what he wants is an HTML browser that
derives its URL data from a file database encoded into ROM.

Has any one tried to make a intenet browser for the gba

Hello,

I don't know if that will suit your needs (it's not exactly a kernel)
but you may find it useful:

http://www.sics.se/~adam/pt/

It's basically very light-weight stackless threads, and it is released
under a BSD-style license.

Hope this helps!

Nicolas.

Hello,

Does anybody know a free multi-tasking kernel for the GBA?
It can be either preemptive or collaborative but must be light weight
and fast.

thanks in advance,
Vital

I am not the author of Xboo, but I did reverse-engineer it with the
help of a disassembler (more than 2 years ago !), and for
a time I dabbled with the possibilities of the cable beyond
just cart transfer. I've regrouped the results of my work
in the attached zip file. I hope it goes through the mailing list,
otherwise just ask and I'll send it directly.

Cheers,
--Jonathan

Hello,

I found an old message in this list asking for the source code of the
Xboo program, but the link mentioned in the answer is no longer active.
Does anybody have the source code to kindly provide me?

It's very very easy to install:
1. Download devkitarm
2. Decompress somewhere (mine is in /home/davidr/devkitarm/ )
3. add devkitarm/bin to your path

That's it for installing! From then on, most gba tutorials will work,
as long as they use makefiles (and not the cursed .bat files).

Here are some GBA Tutorials:

-David R

Tile Quantizer converts 24 bit images in to 8 bit (256 colour) images
that contain 16 colour tiles (16 palettes of 16 colours each).

This resulting 256 colour image can then be used to grab 16 colour
tiles from.

Ah!
And where can I find a good tutorial to install devkitproARM in a
Linux Desktop?

http://devkitpro.sf.net/ might be a better way to go. devkitAdv is a bit
out of date.

Hi guys,
I'm looking for a good docs that explain how to install devkitadv (any
version) in a Linux desktop.
tnx

Hi guys,
I would like to know how I can build a gba project.
Yesterday I did try to do that but I didn't build anything, at first
because the KDevelop
didn't find the right compiler (I wrote the complete path in the
project and, after that, KDevelop found the compiler) and after that
because it didn't find the file crt0.s (even if I did write the
complete path)
Can anybody  help me, please?
Tnx

Hello,

I am working on a personal project that may or may not become
commercial, so I am trying to spend as little money as possible on it.
I am using the EPM570T100 CPLD from altera, and I would like to use
boundary scan to test the board and the firmware.

Does anybody know a free software for boundary scan? any help will be
greatly appreciated.

thanks in advance,
Vital

We are working on a Nintendo DS project and are in need of an
additional contract programmer for the next two months.  Work can be
performed remotely but does require getting together in person a
couple of times per week.

Interested persons with GBA experience (paid or not) can reply to
DSProgrammer@... with your contact info and qualifications.

I'm going to assume it's due to the fact that the compiled 'e1m1' object
isn't being linked in. It's either that or some bad VisualHAM mojo. Try
compiling it w/ the latest devkitARM ( http://devkitpro.sf.net/ ) and
see if it makes any difference.

Hi I fixed it but I am getting the same error. I even  created a map
e1m1.c  using  Yeti3D Editor and replaced it with  the exact same
name the original e1m1.c  but when I still  got this error


: undefined reference to `e1m1'
make: *** [yeti.elf] Error 1

but when I compile it with original I get no errors.

/gcc-arm/bin/arm-thumb-elf-objcopy.exe  -v -O binary yeti.elf

Looks like you forgot to close your function....

yeti_load_map(yeti, &warehouse;

Should be

yeti_load_map(yeti, &warehouse);
