环境：ads2.2+ARM9 +s3c2410
留意：因为编译器(ads1.2或2.2)对全局变量初始化为0的不完全支撑，有时有必要手动初始化为0，牢记!!!
一、ucos II移植到ARM9 s3c2410
可从官网下载移植代码，根本无需改动。
在os_cpu_a.s中的函数UCOS_IRQHandler中的bl OSIntEnter和bl C_IRQHandler之间刺进如下代码(见邵贝贝，第2版，第104页的阐明：L3.18(4) )：
ldr r0, =OSIntNesting
ldrb r0,[r0]
cmp r0,#1
bne XX
ldr r0,=OSTCBCur
ldr r1,[r0]
str sp,[r1] ; store sp in preempted tasks’s TCB
XX
二、ucGui 390移植到ARM9 s3c2410
1. Lcd驱动：
1) 画点函数：
对dm2410试验板上的lcd，左上为原点(0，0)，函数如下：
void LCD2410_SetPixel(int xp, int yp, U16 color, int dindex)
{
*(pLCDBuffer565 + SCREEN_WIDTH*yp + xp) = color;
}
为了到达更快的显现速度，别忘了敞开Cache!!!
2)LCD控制器的初始化，对2410函数如下：
int LCD2410_Init(void)
{
if(!isLcdInit)
{
InitLcdPort();
InitLcdRegs();
isLcdInit = 1;
return 0;
}
return 1;
}
void InitLcdPort(void)
{
// LCD port initialize.
s2410IOP->GPCUP = 0xFFFFFFFF;
s2410IOP->GPCCON = 0xAAAAAAAA;
s2410IOP->GPDUP = 0xFFFFFFFF;
s2410IOP->GPDCON = 0xAAAAAAAA;
s2410IOP->GPGCON = ~(3 8); /* Set LCD_PWREN as output */
s2410IOP->GPGCON |= (1 8);
s2410IOP->GPGDAT |= (1 4); //* Backlight ON
}
void InitLcdRegs(void)
{
s2410LCD->LCDCON1 = (CLKVAL_TFT 8) | //* VCLK = HCLK / ((CLKVAL + 1) * 2) -> About 7 Mhz
(EACH_FRAME 7) | //* 0 : Each Frame
(3 5) | // TFT LCD Pannel
(12 1) | //Y: // 16bpp Mode
(0 0) ; // Disable LCD Output
s2410LCD->LCDCON2 = (VBPD 24) | //* VBPD : ((32-1)0xff) = 0x1f
(LINEVAL_TFT 14) | //* LINEVAL_TFT : 480 – 1
(VFPD 6) | //* VFPD : ((11-1)0xff) = 0xa
(VSPW 0) ; //* VSPW : ((2-1) 0x3f) = 0x1
s2410LCD->LCDCON3 = (HBPD 19) | //* HBPD : ((88-1)0x7f)
(HOZVAL_TFT 8) | //* HOZVAL_TFT : 800 – 1
(HFPD 0) ; //* HFPD : ((40-1)0xff)
s2410LCD->LCDCON4 = (MVAL 8) | //* MVAL : 13
(HSPW 0) ; //* HSPW : ((128-1)0xff)
s2410LCD->LCDCON5 = (0 12) | // BPP24BL : LSB valid
(1 11) | // FRM565 MODE : 5:5:5:1 Format
(0 10) | // INVVCLK : VCLK Falling Edge
(1 9) | // INVVLINE : Inverted Polarity
(1 8) | // INVVFRAME : Inverted Polarity
(0 7) | // INVVD : Normal
(0 6) | // INVVDEN : Normal
(0 5) | // INVPWREN : Normal
(0 4) | // INVENDLINE : Normal
(1 3) | // PWREN : Disable PWREN
(0 2) | // ENLEND : Disable LEND signal
(0 1) | // BSWP : Swap Disable
(1 0) ; // HWSWP : Swap Enable
s2410LCD->LCDSADDR1 = ((FRAMEBUF_DMA_BASE >> 22) 21) |
((M5D(FRAMEBUF_DMA_BASE >> 1)) 0);
s2410LCD->LCDSADDR2=M5D( (FRAMEBUF_DMA_BASE+(LCD_XSIZE_TFT*LCD_YSIZE_TFT*2))>>1 );
s2410LCD->LCDSADDR3=(((LCD_XSIZE_TFT-LCD_XSIZE_TFT)/1)11)|(LCD_XSIZE_TFT/1);
s2410LCD->LCDINTMSK|=(3); // MASK LCD Sub Interrupt
s2410LCD->LPCSEL=(~7); // Disable LPC3600
s2410LCD->TPAL=0; // Disable Temp Palette
s2410LCD->LCDCON1 |= 1;
}
其间，部分变量、常量界说如下：
#define LCD_XSIZE_TFT (800)
#define LCD_YSIZE_TFT (480)
#define HOZVAL_TFT (LCD_XSIZE_TFT-1)
#define LINEVAL_TFT (LCD_YSIZE_TFT-1)

2.触摸屏驱动：
触摸屏驱动计算出触摸屏的坐标(x，y)，对dm2410试验板上的触摸屏，左下为原点，但不一定是(0，0)。两个函数：
