16bit Routines Issue

[Alessandro]

Yo
I'm using the devkitadv and the minigp32 SDKs and everything works right..

I've seen, reading the GP32SDK Api Reference, that there are routines specific for 16bit modes (like GpRectFill16, GpBitBlt16,... ) but I can't get them to work, since there's no gpgraphic16.h and no gpgraphic16.a in the devkits.. :huh:

Can somebody please helpme?!

Best regards
Alessandro

from what i remember...

edit C:\devkitadv\gp32.mk (this is for Rico's devkitadvance!)

where its says:

GPLIBS=-lgpsdk -lgpgraphic -lgpmem -lgpos -lgpstdlib -lgpstdio -lgpsound -lgpfont -lgpg_ex01

add -lgpgraphic16 and -lgpfont16 to the list

then extract the .a to:

C:\devkitadv\arm-agb-elf\lib

and yes, extract the .h and .c to:

C:\devkitadv\arm-agb-elf\include\gp32

the last bit if i remember correctly, you have to 'make' the MakeFile:

C:\devkitadv\arm-agb-elf\lib\gpsdk\MakeFile

good luck!

Thanks Ksmiler
Now I got it to work.. but as the other guys reported, I have issues with GpPointSet16.. It's working right with GpRectFill16, (i see the reft filled on the screen, but if I use the GpPointSet16 i have nothing) :blink:

Hope you can help.

Thanks again.

GpPointSet16 indeed has issues. Just use your own routine like this one:

void PutPixel16(int x, int y, int c)
{
	unsigned short *p_buf;
	p_buf = (unsigned short *)(gpDraw[nflip].ptbuffer);
	*(p_buf + x*240 + (239-y)) = c;
}

I can not take credit for this routine, but I took it from someones GP32 site so long ago I can't remember who it was. Sorry for this :unsure:

Thanks VirtuaLeech.

It reminds me the old ModeX coding stuff :lol:

Why didn't I thought before? hehehehhe
