AT91SAM9263 WINCE 6.0 R2驱动开发-官方BSP包TFTLCD显示调试

1.在官方包的基础上修改管脚配置如下后：

const struct pio_desc hw_pio[] = {
{"VSYNC",	AT91C_PIN_PC(0),	0, PIO_DEFAULT, PIO_PERIPH_A},
{"HSYNC",	AT91C_PIN_PC(1),	0, PIO_DEFAULT, PIO_PERIPH_A},
{"DOTCK",	AT91C_PIN_PC(2),	0, PIO_DEFAULT, PIO_PERIPH_A},
{"EN",		AT91C_PIN_PC(3),	0, PIO_DEFAULT, PIO_PERIPH_A},

{"D0",		AT91C_PIN_PC(4),	0, PIO_DEFAULT, PIO_PERIPH_B},
{"D1",		AT91C_PIN_PC(5),	0, PIO_DEFAULT, PIO_PERIPH_B},
{"D2",		AT91C_PIN_PC(6),	0, PIO_DEFAULT, PIO_PERIPH_B},
{"D3",		AT91C_PIN_PC(7),	0, PIO_DEFAULT, PIO_PERIPH_B},
{"D4",		AT91C_PIN_PC(8),	0, PIO_DEFAULT, PIO_PERIPH_B},

{"D5",		AT91C_PIN_PC(9),	0, PIO_DEFAULT, PIO_PERIPH_B},
{"D6",		AT91C_PIN_PC(10),	0, PIO_DEFAULT, PIO_PERIPH_B},
{"D7",		AT91C_PIN_PC(11),	0, PIO_DEFAULT, PIO_PERIPH_B},
{"D8",		AT91C_PIN_PC(12),	0, PIO_DEFAULT, PIO_PERIPH_B},
{"D9",		AT91C_PIN_PC(13),	0, PIO_DEFAULT, PIO_PERIPH_B},
{"D10",		AT91C_PIN_PC(14),	0, PIO_DEFAULT, PIO_PERIPH_B},

{"D11",		AT91C_PIN_PC(15),	0, PIO_DEFAULT, PIO_PERIPH_B},
{"D12",		AT91C_PIN_PC(16),	0, PIO_DEFAULT, PIO_PERIPH_B},
{"D13",		AT91C_PIN_PC(17),	0, PIO_DEFAULT, PIO_PERIPH_B},
{"D14",		AT91C_PIN_PC(18),	0, PIO_DEFAULT, PIO_PERIPH_B},
{"D15",		AT91C_PIN_PC(19),	0, PIO_DEFAULT, PIO_PERIPH_B},

{"CC",		AT91C_PIN_PB(9),	0, PIO_DEFAULT, PIO_PERIPH_B},

};

pio_setup(hw_pio, sizeof(hw_pio)/sizeof(struct pio_desc));
//screen contrl
const struct pio_desc hw_pioe17[] =
{
{"LCD_POWEREN",	AT91C_PIN_PE(17), 0, PIO_PULLUP, PIO_OUTPUT},
};
pio_setup(hw_pioe17, sizeof(hw_pioe17) / sizeof(struct pio_desc));
pio_set_value(AT91C_PIN_PE(17), 0);

2.修改注册表重新编译即可

[HKEY_LOCAL_MACHINE/System/GDI/ROTATION]
"Angle"=dword:00

; Video driver settings
[HKEY_LOCAL_MACHINE/Drivers/Display/LCDC]
;the board does have 320x240 16 bpp color LCD
"Width"=dword:140
"Height"=dword:F0
"Bpp"=dword:10                 ; Bit per pixel
"VRAMWidthInPixel"=dword:200   ; Frame buffer width in pixel (must be at least screen width value and also must match the 2DGE settings. keeping it aligned on 4 bytes allows not to care about the later)
"VRAMHeightInPixel"=dword:200 ; Frame buffer heigth in pixel (must be at least screen height and more than twice for directdraw)
"VRAMaddress"=dword:23e00000 	; Frame buffer location. Here allocate the video memory in SDRAM

"forceRGB"=dword:1           ; uncomment this line if you want to use DirectDraw,
; be careful, the color will be shifted

"TOTAL MONITORS"=dword:1

[HKEY_LOCAL_MACHINE/System/GDI/Drivers]

3.注意

可能会出现板子TFTLCD颜色显示不正常的情况，此时修改"forceRGB"=dword:1注册表项即可
