/************************************************************* test_main.c : Nintendo 64 Music Tools Library Sample (c) Copyright 1998, Software Creations (Holdings) Ltd. Version 3.11 TESTMENU demo main source file. Uses a simple menu to illustrate the use of various music library functions. Once executed use the Dpad to navigate up-down and change setting with left-right, for settings with a large range use the shoulder buttons for larger changes. The A button executes the menu command. The B button will stop all currently running channels. **************************************************************/ /* include system header files */ #ifndef F3DEX_GBI #define F3DEX_GBI #endif #include #include #include /* include current header file */ #include "test_rom.h" /* prototypes */ void StartThread (void *ignored); void GameThread (void *ignored); void MainLoop (void); int InitMusicPlayer (void); /* stack sizes */ #define BOOTSTACK_SIZE (STACKSIZE) #define MAINSTACK_SIZE (STACKSIZE) /* size of the DMA queue */ #define DMA_QUEUE_SIZE 200 /* number of serial messages to support */ #define SERIAL_MESGS 4 /* all geometry modes */ #define GEOM_ALL G_SHADE|G_SHADING_SMOOTH|G_CULL_BOTH|G_FOG|G_LIGHTING|G_TEXTURE_GEN|G_TEXTURE_GEN_LINEAR|G_LOD /* load projection and model matrices */ #define LOAD_PROJ (G_MTX_PROJECTION|G_MTX_LOAD|G_MTX_NOPUSH) #define LOAD_MODEL (G_MTX_MODELVIEW|G_MTX_LOAD|G_MTX_NOPUSH) /* macros - background colour for screen (all three components) */ #define BGCOL 0 /* graphics task message structure */ typedef union { short type; OSScMsg app; } message_t; /* graphics information structure */ typedef struct { OSScTask task; message_t mess; unsigned short *screen; } info_t; /* scheduler structure */ OSSched sc; /* threads */ OSThread gameThread; OSThread mainThread; /* thread stacks */ u64 bootStack [BOOTSTACK_SIZE/8]; u64 mainThreadStack [MAINSTACK_SIZE/8]; u64 scheduleStack [OS_SC_STACKSIZE/8]; /* workspace - message queues */ OSMesgQueue pi_queue; OSMesg pi_messages [DMA_QUEUE_SIZE]; OSMesgQueue gfx_queue; OSMesg gfx_messages [MAX_MESGS]; OSMesgQueue dma_queue; OSMesg dma_messages [MAX_MESGS]; OSMesgQueue serial_queue; OSMesg serial_messages [SERIAL_MESGS]; /* controller pad workspace */ OSContPad controllerdata [MAXCONTROLLERS]; OSContStatus statusdata [MAXCONTROLLERS]; /* double buffered graphic information */ info_t info[2]; /* Entry point */ void boot(void *ignored) { osInitialize(); osCreateThread(&mainThread, 1, StartThread, NULL, (void *)(mainThreadStack+MAINSTACK_SIZE/8), (OSPri)MAIN_PRIORITY); osStartThread(&mainThread); } /* base thread */ void StartThread(void *ignored) { /* start PI manager for ROM access */ osCreatePiManager((OSPri) OS_PRIORITY_PIMGR, &pi_queue, pi_messages, DMA_QUEUE_SIZE); /* create game thread and start it */ osCreateThread(&gameThread, 6, GameThread, NULL, bootStack+BOOTSTACK_SIZE/8, (OSPri)GAME_PRIORITY); osStartThread(&gameThread); /* become idle thread */ osSetThreadPri(0, 0); for(;;); } /* application thread */ void GameThread(void *ignored) { OSScClient client; u8 pattern; int mode; /* create message queues */ osCreateMesgQueue(&dma_queue, dma_messages, MAX_MESGS); osCreateMesgQueue(&serial_queue, serial_messages, SERIAL_MESGS); /* map relevant events to the queues */ osSetEventMesg(OS_EVENT_SI, &serial_queue, (OSMesg)1); /* initialize default scheduler using "osTvType" */ if (osTvType==0) mode = OS_VI_PAL_LAN1; /* --- PROGRAMMING CAUTION --- */ else if (osTvType==1) /* Applications must not use "ovTvType" to switch the TV */ mode = OS_VI_NTSC_LAN1; /* system from NTSC to PAL or PAL to NTSC.
