GP32 Mr.mirkos Sdk Replacement

[mr.spiv]

A trick... assuming one uses a crt0 that sets up stack pointer correctly..
Linker defines a symbol end_ and end. Substract that value from the current stack pointer value and you have the anount of free heap the newlib malloc() can use.

Iam now learing arm9 asembler to write some nice sprite libs ( rotating/stretching/moving/... ) (help wanted....)
[...]

Just wondering if you are still working on these routines

Are you going to add asm routines like "box", "circle", "line", "point"...etc?


btw, you're great!

I keep the SDK a little "low-level",

i add line/box/circle function this weekend...

( drawing a point is already in it )

lets see what my little asm knowlege can offer

 

[mr.mirko]

SDK.082

- rewrote gp_setFramebuffer to fit 1,2,4,8,16 Bit modes
- new gp_drawLine16 included... ( nice fast )
- extended sprite header to work with different sprite formats
- new gp_drawSpriteHTB included... ( Alpha Blending on sprites )
- new example.sprite to show alpha blending on sprites

HAVE FUN

Hey I'm not a developer but I think there would be alot more Multiplayer games for the GP32 if you added RF link Support, would there be any problems with doing that?

Yes, i have no money for a second gp32,and 2 rf modules ...

 

[Enslaved]

yeah I agree, RF links are very expensive! Maybe the euro launch will have cheaper ones? But that doesnt really solve the only 1 GP32 problem. Why doesnt someone upgrade GeePee32 somehow to include simulated RF link with 2 screens?

 

[Tharo]

cos there is alot other stuff that should be fixed in geepee32 first.
But if firefly have no fun to continue his work (or other reasons) so let him and start an own emulation project

 

[synkro]

well, a better working geepee32 would be great, cause it would dmak deving a lot easier, at least for me...

Hi,

iam working on a new html online doc, see the first impressions here:

http://www.mirkoroller.de/gp32/doc.html

What do you think ?
It will replace the rtf in the near future.

 

[ThunderZ]

Hooo GooD Work and very detailled.

Good job Mirko

 

[synkro]

great! this is way better than those PDFs, but why don't you try it like javadoc or NDOC?it's well known and easy way to document stuff...

Mirko,

Whenever I try to reach your HP, I do not succeed.

Are there special times when it is online ?

hi,

just a quick note, that iam working on a irq/timer4 modplayer and mixer.
So you can playback a modfile, and sound effects at the same time. ( very easy setup )

Its to 99% ready, just watch this board the next days

 

[synkro]

oh my fucking gosh! He did it! Hail to the King!

 

[perishabl]

is there any chance of getting windows executables of the 'bmp2bin', 'convert', and 'zcontainer' tools included in the SDK download? I know a previous version I was experimenting with (081, maybe?) had one for bmp2bin, but not the others, and the current version seems to only have ELF binaries...

 

[mr.mirko]

SDK 083

- Realtime soundmixer of samples
- easy Amiga modfile playback
- click free at all clockrates ( 33-156 )

Complete new soundpart. The soundmixer is timer/irq based, that means
you can now playback a amiga modfile, and samples with sound effects
at the same time, mixed in realtime, and running in background.

have fun.

?

nice work man!!!
running fine with ads
now i'm going to add sounds+music to c-dogs port....

btw: for all your #defines in gp32.h you should make them perfix with GP32_ or somthing because some interfers with custom app defines... like for WIDTH and HEIGHT
