| PCM means pulse code modulation. I think it is just a bit stream format for audio data as opposed to a file type. |

Quote: you're right. it's missing the main.c. does anyone have this file? also, the Makefile is broken (you can fix it by replacing spaces in front of the compile lines with TAB) Did he do his follow up articles? I'd like to read them. His email is bouncing. :( I guess 6 years of spam would make me close my account too... :) [Edited by - subatomic on June 24, 2008 9:20:06 PM] |

| ok, I wrote the main.cpp here it is (works just like the original): #include "sfx.h" #include "Bullhorn.h" #include "Gunfire.h" int main() { // video mode4, bg2 on *(unsigned long*)0x4000000 = 0x403; // clear screen to black unsigned short* Screen = (unsigned short*)0x6000000; u32 y, x; for(y = 0; y<160; y++) //loop through all y pixels for(x = 0; x<240;x++) //loop through all x pixels Screen[x+y*240] = 0; init_sfx_system(); SAMPLE sample1; sample1.pData = (char*)BullhornRawAudio; sample1.length = sizeof( BullhornRawAudio ); SAMPLE sample2; sample2.pData = (char*)GunfireRawAudio; sample2.length = sizeof( GunfireRawAudio ); #define MEM_IO 0x04000000 #define REG_CTRLINPUT (*(volatile u16 *)(MEM_IO + 0x130)) #define CTRLINPUT_A_PRESSED (~REG_CTRLINPUT & 0x0001) #define CTRLINPUT_B_PRESSED ((~REG_CTRLINPUT & 0x0002) >> 1) while (1) { if (CTRLINPUT_A_PRESSED) { play_sfx( &sample1 ); } if (CTRLINPUT_B_PRESSED) { play_sfx( &sample2 ); } } } =============== To get this to compile on my devkitadvance R5 beta 3, I had to remove the lnkscript from the makefile: =============== CFLAGS = -c -O3 MODEL = -mthumb -mthumb-interwork all : demo01.gba demo01.gba: demo01.elf objcopy -O binary demo01.elf demo01.gba run: demo01.gba VisualBoyAdvance demo01.gba sfx.o: sfx.c sfx.h gba.h gcc $(CFLAGS) $(MODEL) sfx.c main.o: main.c sfx.h gba.h gcc $(CFLAGS) $(MODEL) main.c demo01.elf : main.o sfx.o gcc $(MODEL) -o demo01.elf main.o sfx.o http://www.subatomicglue.com |
