説明

NDS hardware definitions.

These definitions are usually only touched during the initialization of the program.

マクロ定義

#define argvMagic   0x5f617267

#define DISP_HBLANK_IRQ   BIT(4)

Interrupt on horizontal blank.

#define DISP_IN_HBLANK   BIT(1)

The display currently in a horizontal blank.

#define DISP_IN_VBLANK   BIT(0)

The display currently in a vertical blank.

#define DISP_VBLANK_IRQ   BIT(3)

Interrupt on vertical blank.

#define DISP_YTRIGGER_IRQ   BIT(5)

Interrupt when current scanline and DISP_Y match.

#define DISP_YTRIGGERED   BIT(2)

Current scanline and DISP_Y match.

#define HALT_CR   (*(vuint16*)0x04000300)

Halt control register.

Writing 0x40 to HALT_CR activates GBA mode. HALT_CR can only be accessed via the BIOS.

#define libnds_argv   ((struct __argv *)0x027FFF70)

Default location for the libnds argv structure.

#define PersonalData   ((PERSONAL_DATA*)0x27FFC80)

Default location for the user's personal data (see PERSONAL_DATA).

#define POWER_2D_A   BIT(1)

#define POWER_2D_B   BIT(9)

#define POWER_3D_CORE   BIT(3)

#define POWER_ALL   (POWER_ALL_2D | POWER_3D_CORE | POWER_MATRIX)

Enables power to all hardware required for 3D video.

#define POWER_ALL_2D   (POWER_LCD |POWER_2D_A |POWER_2D_B)

Enables power to all hardware required for 2D video.

#define POWER_LCD   BIT(0)

#define POWER_MATRIX   BIT(2)

#define POWER_SWAP_LCDS   BIT(15)

#define REG_DISPSTAT   (*(vu16*)0x04000004)

LCD status register.

#define REG_KEYCNT   (*(vuint16*)0x04000132)

Key input control register.

#define REG_KEYINPUT   (*(vuint16*)0x04000130)

Key input register.

On the ARM9, the hinge "button," the touch status, and the X and Y buttons cannot be accessed directly.

#define REG_POWERCNT   *(vu16*)0x4000304

Power control register.

This register controls what hardware should be turned on or off.

#define REG_VCOUNT   (*(vu16*)0x4000006)

Current display scanline.

型定義

typedef struct tPERSONAL_DATA PERSONAL_DATA

関数

static void lcdMainOnBottom ( void   )  [inline, static]

Forces the main core to display on the bottom. 

00143 { REG_POWERCNT &= ~POWER_SWAP_LCDS; }

static void lcdMainOnTop ( void   )  [inline, static]

Forces the main core to display on the top. 

00140 { REG_POWERCNT |= POWER_SWAP_LCDS; }

static void lcdSwap ( void   )  [inline, static]

Switches the screens. 

00137 { REG_POWERCNT ^= POWER_SWAP_LCDS; }

static void powerOFF ( int  off  )  [inline, static]

Turns off the specified hardware.

引数:
off What to power off. 
00102 { REG_POWERCNT &= ~off;}

static void powerON ( int  on  )  [inline, static]

Turns on specified hardware.

This function should only be called after powerSET.

引数:
on What to power on. 
00089 { REG_POWERCNT |= on;}

static void powerSET ( int  on  )  [inline, static]

Turns on only the specified hardware.

Use this function to power on basic hardware types you wish to use throughout your program.

引数:
on What to power on. 
00097 { REG_POWERCNT = on;}

static void SetYtrigger ( int  Yvalue  )  [inline, static] 

00063                              {
00064         REG_DISPSTAT = (REG_DISPSTAT & 0x007F ) | (Yvalue << 8) | (( Yvalue & 0x100 ) >> 2) ;
00065 }
