wince开机界面的修改方法之一

修改wince开机界面logo
硬件环境：6410 + 3.5寸的屏，
1.图片格式为160*120  真彩色  用bmp2c转换后的图片数组为unsigned short 类型。

首先将图片转换成数组，这里用的工具是bmp2c，将转换后的数组替换wince600->PLATFORM->SDK6410->src>bootloader->eboot  ->InitialImage_rgb16_320x240.h中的数组InitialImage_rgb16_320x240[]。

在VS2005里的wince 6.0的工程文件目录下找到wince600->PLATFORM->SDK6410->src  ->bootloader->eboot  ->main.c下的void InitializeDisplay(void)函数。

将static void InitializeDisplay(void)中的

#if(SMDK6410_LCD_MODULE == LCD_MODULE_HUA350)
    memcpy((void *)EBOOT_FRAMEBUFFER_UA_START, (void *)InitialImage_rgb16_320x240, 320*240*2);
#elif    (LCD_BPP == 16)
    {
        int i;
        unsigned short *pFB;
        pFB = (unsigned short *)EBOOT_FRAMEBUFFER_UA_START;

        for (i=0; i             *pFB++ = 0x0000;//0x001F;        // Blue

 

修改为：
#if(SMDK6410_LCD_MODULE ==LCD_MODULE_QIM350)
    //memcpy((void *)EBOOT_FRAMEBUFFER_UA_START, (void *)InitialImage_rgb16_320x240, 320*240*2);
 
 
 {
   int i;
  for(i = 0; i < LCD_WIDTH*LCD_HEIGHT/2; i++)
  {
   PWORD pWord = (PWORD)InitialImage_rgb16_320x240;
   PWORD pFrmBuf = (PWORD)EBOOT_FRAMEBUFFER_UA_START;          
        pFrmBuf[2 * i - 1* (i % LCD_WIDTH)] = pWord[i];
        pFrmBuf[2 * i - 1 * (i % LCD_WIDTH) + LCD_WIDTH] = pWord[i]； //图片相当于纵向拉伸了2倍，
   //pFrmBuf[4 * i - 2 * (i % 160)] = pWord[i];
   //pFrmBuf[4 * i - 2 * (i % 160) + 1] = pWord[i];
   //pFrmBuf[4 * i - 2 * (i % 160) + 160 * 2] = pWord[i];
   //pFrmBuf[4 * i - 2 * (i % 160) + 1 + 160 * 2] = pWord[i];
  }

 }

或者拷贝内存块填充显示缓存Framebuffer； 
  {

  int i = 0;
  PWORD p = (PWORD)InitialImage_rgb16_320x240;
  PWORD dst = (PWORD)EBOOT_FRAMEBUFFER_UA_START;
  for (i = 1;i <= LCD_HEIGHT;i++)
  {
   memcpy(dst, p,  LCD_WIDTH*2);
   if(i%2 == 0)
     p  += LCD_WIDTH;
   dst += LCD_WIDTH;

  }
 }

 

然后编译eboot，下载烧录eboot。

2.图片格式为320*240  真彩色 用bmp2c转换后的图片数组为unsigned short 类型

    {
  int i;
  unsigned int value_temp = 0;
  unsigned int *pWord = (unsigned int)InitialImage_rgb16_320x240;
  unsigned int *pFrmBuf = (unsigned int)EBOOT_FRAMEBUFFER_UA_START;
  for(i = 0; i <   LCD_WIDTH*LCD_HEIGHT; i++)
  {
     value_temp =(pWord[i]<<16) | pWord[i+1];

     pFrmBuf[i/2] = value_temp;
   
     i++;
   //pFrmBuf[i] = pWord[i];
  }

  }

3，图片格式为320*240  真彩色 用Image2Lcd转换数组为unsiged char类型
// 图片数组为unsiged char类型，指向图片数组InitialImage_rgb16_320x240的指针pWord 为unsigned int类型，
// 从内存里取值是按int类型取值的，相当于取了4个char类型的值，而存放char类型数组是整块空间

  {
  int i;
  unsigned int value_temp = 0;
  
  unsigned int *pWord = (unsigned int)InitialImage_rgb16_320x240;
  unsigned int *pFrmBuf = (unsigned int)EBOOT_FRAMEBUFFER_UA_START;
  for(i = 0; i   {
    // value_temp =(pWord[i]<<16) | (pWord[i+1]);

   //  pFrmBuf[i/2] = value_temp;
  
    // i++;
   pFrmBuf[i] = pWord[i];
  }

 }
或者直接拷贝内存分配给图片数组的数据
