EBOOT升级进度条

VOID BspEbootUpdateShowProgressBar(BYTE phase, BYTE percent)

{

    if (!g_bScreenInited || percent > 100)

        return;



    BspEbootUpdateProgressString(phase, 0);//，调用DrawString()来打印对应的字符串


    if (percent < oldPercent)

        FillRectangle(g_dwPgrBorderLeft + 1, g_dwPgrBorderTop + 1, g_dwPgrBorderLeft + PGR_BAR_WIDTH,

                      g_dwPgrBorderTop + PGR_BAR_HEIGHT, g_hCurrentDC->bkcolor);



    oldPercent = percent;



    FillRectangle(g_dwPgrBorderLeft + 1, g_dwPgrBorderTop + 1, g_dwPgrBorderLeft + PGR_BAR_WIDTH* percent / 100,

                  g_dwPgrBorderTop + PGR_BAR_HEIGHT, XBLUE);//设定填充宽度

WINCE6开机进度条 

　　大致思路，在NBoot 或EBoot 加开机进度条，由于WINCE 启动主要时间都花在读取NK ，因此每读取一定的页，就在屏上画一条固定高度的线，并记录画线的位置，下次接着画，直到读取完NK ，这样就产生的进度条的效果。
参考Mini2440 Nboot。

先定义进度条颜色、位置及长宽，关键代码如下：

 

#define PROGRESS_BAR_R 0x00
#define PROGRESS_BAR_G 0xFF
#define PROGRESS_BAR_B 0x00

//设置启动条的位置和长宽
#define PROGRESS_BAR_TOP    225
#define PROGRESS_BAR_LEFT   145
#define PROGRESS_BAR_WIDTH  512
#define PROGRESS_BAR_HEIGHT  20
#define PROGRESS_BAR_COLOR  ( ( (PROGRESS_BAR_R >> 3) << 11) | ((PROGRESS_BAR_G >> 2) << 5) | (PROGRESS_BAR_B >> 3) )

#define PROGRESS_BAR_R 0x00 #define PROGRESS_BAR_G 0xFF #define PROGRESS_BAR_B 0x00 //设置启动条的位置和长宽 #define PROGRESS_BAR_TOP 225 #define PROGRESS_BAR_LEFT 145 #define PROGRESS_BAR_WIDTH 512 #define PROGRESS_BAR_HEIGHT 20 #define PROGRESS_BAR_COLOR ( ( (PROGRESS_BAR_R >> 3) << 11) | ((PROGRESS_BAR_G >> 2) << 5) | (PROGRESS_BAR_B >> 3) )

在读取NK 前计算出读取开始画线的位置

 

 

unsigned  char  *LCDCurrentAddr;
LCDCurrentAddr = (unsigned char  *)LCD_ADDR + PROGRESS_BAR_TOP * LCD_WIDTH * 2 + PROGRESS_BAR_LEFT * 2; // LCD_ADDR为屏地址

unsigned char *LCDCurrentAddr; LCDCurrentAddr = (unsigned char *)LCD_ADDR + PROGRESS_BAR_TOP * LCD_WIDTH * 2 + PROGRESS_BAR_LEFT * 2;// LCD_ADDR为屏地址

 

 

 

根据 NK 长度及进条度长度，计算出每读取多少页就画一条线，画线关键代码

unsigned  short  *p = (unsigned  short  *)LCDCurrentAddr;
for  (y = 0; y < PROGRESS_BAR_HEIGHT; y++)
{
    *p = PROGRESS_BAR_COLOR;
    p += LCD_WIDTH;
}
LCDCurrentAddr += 2;

unsigned short *p = (unsigned short *)LCDCurrentAddr; for (y = 0; y < PROGRESS_BAR_HEIGHT; y++) { *p = PROGRESS_BAR_COLOR; p += LCD_WIDTH; } LCDCurrentAddr += 2;
