GP32 Mr.mirkos Sdk Replacement

[mr.mirko]

Hy,

updated the SDK to Version 0.3.

New Features:
- a lot bugfixes in all modules ( over 50, cant count them )
- SMC Read and Write support, with example
- added double buffering of Screen example

In my opinion the basic options in the SDK are now complete.
All major functions are working now.
There are now 7 examples, showing How to use the SDK.

ToDo:
- Sound mixer, bugs, new features , ...

GET IT NOW

Hi,

I have a problem to download this SDK.

www.mirkoroller.de can't DNS resolved.

please send SDK to me via email to 'piiix@passmail.to_nospam'

and link SDK on other http server.

thankyou for your support,

ouch! me hates bugfixing

How are you going to document it? doxygen?

@nanjungho / Korea: welcome dude!

Hy, i setup a WEB Page with all my GP32 stuff,

here you can donwload always the latest version of the SDK Replacement,
and all other projects iam working on.

Hi ! I'd like to try your SDK, but i really don't know how to set up a compiler and the tool that i need to compile the example ...

I've only used devkitadv from now ...

Can you help me ? Thank you !

Q: How to Cross Compile gcc 3.4, and use my SDK lib ??
A: Read on.

Download:
ftp://ftp.mpi-sb.mpg.de/pub/gnu/mirror/ft...ils-2.14.tar.gz
ftp://sources.redhat.com/pub/newlib/newlib-1.11.0.tar.gz
ftp://ftp.gwdg.de/pub/misc/gcc/snapshots/...0040202.tar.bz2
And of course my SDK

mkdir gp32
mv binutils-2.14.tar.gz newlib-1.11.0.tar.gz gcc-3.3-20040202.tar.bz2 gp32
cd gp32

declare -x CFLAGS="-s "
tar xvfz binutils-2.14.tar.gz
cd binutils-2.14/
./configure --target=arm-elf --prefix=/opt/gp32_gcc && make
make install
cd ..

tar xvfz newlib-1.11.0.tar.gz
tar xvfj gcc-3.3-20040202.tar.bz2
cd gcc-3.4-20040202
ln -s ../newlib-1.11.0/newlib .
mkdir build
cd build

CFLAGS="-pipe -s "
../configure --target=arm-elf --prefix=/opt/gp32_gcc --with-cpu=arm9 --disable-threads --enable-languages=c,c++ --with-newlib --disable-multilib --with-gnu-ld --with-gnu-as

#The following is ONE LINE
make all \
CFLAGS_FOR_TARGET="-DTAG_CFLAGS_FOR_TARGET -s -march=armv4t -marm -msoft-float \
-ffast-math -fshort-enums -mstructure-size-boundary=8 -O2" \
CXXFLAGS_FOR_TARGET="-DTAG_CXXFLAGS_FOR_TARGET -s -march=armv4t -marm -msoft-float \
-ffast-math -fshort-enums -mstructure-size-boundary=8 -O -fno-implicit-templates" \
LIBCFLAGS_FOR_TARGET="-DTAG_LIBCFLAGS_FOR_TARGET -s -march=armv4t -marm -msoft-float \
-ffast-math -fshort-enums -mstructure-size-boundary=8 -O2" \
LIBGCC2_CFLAGS="-DIN_GCC -DCROSS_COMPILE -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -W -Wall \
-Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -isystem ./include -Dinhibit_libc \
-fno-inline -DTAG_LIBGCC_FLAGS -s -march=armv4t -marm -msoft-float -O2 -ffast-math -fshort-enums -mstructure-size-boundary=8"

make install
cd ../..

Now you arm cross compiler is installed in : /opt/gp32_gcc
You can now remove the gp32 dir.

Now set a Path to the new arm-elf-* files
export PATH=/opt/gp32_gcc

You can use the SDK03 from whereever you want.

Woo !

Thank you !

Hi, all

I need simple timer API.
How can I implement Timer or GpTickCountGet() like function?
Show me the simple way plz,

regards,

-nanjungho

PS:
Mr.Mirkos's SDK very nice. It works fine with ArmAds 1.2.
Thanx,

 

[loki666]

ok im trying to compile you sdk against ads...
but there is some problems with the smc lib

from "smf_io.c"
for (i = 0; i < read_size; ++i, ++p_buf)
{
*p_buf = SM_READ_DATA(drv_no);
}
with #define SM_READ_DATA(drv_no) ({unsigned char data; rPDDAT &=~ 0x100; data = (rPBDAT & 0xFF); rPDDAT |= 0x100; data; }) from "smf_conf.h"

how could this works??? your marco for SM_READ_DATA nevers return the unsigned char data...

for the compiler...
*p_buf = ({unsigned char data; rPDDAT &=~ 0x100; data = (rPBDAT & 0xFF); rPDDAT |= 0x100; data; }) ... this means nothing (what's assigned to *p_buf???)

is this really working for you??? because its very weird...
i think you should make function for this (no a simple define)

 

[loki666]

nanjungho... could you post your ads version
specially the .s files

I guess this applys to not to windows, right? any help for this?

 

[nanjungho]

opoos,

I'm not tested smc library,

I just modified crt0.S and then link with Mr.Mirkos's ready made SDK library(*.a),

some sample works good, but fire and smc example have some problam,

I can't fix it, I just beginning for ARM .

Anyway, I hope u solve them soon..

keep going..

[nanjungho]

to loki666

with #define SM_READ_DATA(drv_no) ({unsigned char data; rPDDAT &=~ 0x100; data = (rPBDAT & 0xFF); rPDDAT |= 0x100; data; }) from "smf_conf.h"

I've recompiled and tested smc library for ADS1.2
Maybe *p_buff = data requared.
so I made function like below

unsigned char SM_READ_DATA()
{
unsigned char data; rPDDAT &=~ 0x100; data = (rPBDAT & 0xFF); rPDDAT |= 0x100; return data;
}

and redefined #define SM_READ_DATA(drv_no) SM_READ_DATA()
now Mr.Mirkos's smc example works fine.

and smf_uni.c has Korean double byte char to unicode function support,
In my think that function is useless for not Korean.
You can remove smf_uni.c file from project.
and redefine need somewhere..

#define SM_MBS_TO_UNICODE strncpy

that's all.
and thanx for reading my lame english.

Mirko, I was wondering if you knew whether your SMC functions are faster than the official SDK?

One of the problems I have with reading from the SMC is the speed is so slow, and the functions are blocking so I can't go do something else with the cpu whilst waiting.

Is it possible to have a non-blocking read/write with the SMC?

 

[mr.mirko]

thanx nanjungho for your help, i removed the unicode code, and its still working fine And it saved a few bytes...

RobertJ: No, the cpu is not blocked while reading from smc card, you can still use irqs and DMAs, it it possible to read a mp3/ogg in 4/8 kb blocks, and output the sound.

 

[RobertJ]

Mirko, any chance of some C sample code for IRQ/DMA routines, for example something that would be useful for being called regularly to update the display. check the audio buffer isn't running out, read controller inputs?

The equivalent of the GpTimer functions into your SDK would be a great addition!

 

[mr.mirko]

Hy,

just a remider, i updated the SDK to Version 0.4

- removed unicode from smc ( the smc lib gets 10kb smaler )
- SDK now compiles with ADS1.2 ( thanx nanjungho )
- added a new Example, its my conversion of the nspmod lib,
You can now easy playback modfiles with the SDK
- of couse some bugfixes ...

ToDO:
Iam hardly working on a new soundcore, if its ready, you can mix
unlimited samples at the same time

cheers,
Mr.Mirko

[synkro]

just great! keep on going!
you already set up a road map or something? future features?

nspmodlib could be easier to use, remember CHN's modlib is easy as hell..

MODPlay_Init ( &mp );
    MODPlay_SetMOD ( &mp, sonorous );
    MODPlay_Load ( &mp, "gp:\\your.mod" );
    MODPlay_Start ( &mp );

 

[mr.mirko]

just great! keep on going!

Yes, there are a lot of things i like to add:

8Bit Grafik mode with palette loading support
unzip support, to use zipped data easy
Selectable fonts 7x7 8x8 and 9x9 size
basic drawing functions ( point,line,... )
sound mixer with unlimited voices
smaller smc lib

Its a lot work, but i like to code it

Lets see how mutch free time, porting mame, offers me
