关键修改代码记录：

修改点1：

注:为了使ucgui 适配 32 bit per pixsel 

typedef union {
  U32  aColorIndex8[2];
  U32 aColorIndex16[2];
} LCD_COLORINDEX_UNION;

关键修改点2：

注：此处修改主要是为适配linuxframbuffer

struct fb_var_screeninfo g_vinfo;
int g_fbfd, g_fbsize;
unsigned char *g_fbbuf;
void init_dummy_driver(void)
{
/* Open video memory */
if ((g_fbfd = open("/dev/fb0", O_RDWR)) < 0) {
 exit(1);
}
/* Get variable display parameters */
if (ioctl(g_fbfd, FBIOGET_VSCREENINFO, &g_vinfo)) {
 printf("Bad vscreeninfo ioctl/n");
 exit(2);
}
/* Size of frame buffer */
g_fbsize = g_vinfo.xres*g_vinfo.yres*(g_vinfo.bits_per_pixel/8);
/* Map video memory */
if ((g_fbbuf = mmap(0, g_fbsize, PROT_READ | PROT_WRITE,
 MAP_SHARED, g_fbfd, 0)) == (void *) -1) {
 exit(3);
}
}
void deinit_dummy_drivr(void)
{
munmap(g_fbbuf, g_fbsize);
close(g_fbfd);
}

关键修改点3：

注：使ucgui 适配 32 bit per pixsel 

#define I16   signed int    /*   signed 16 bits. */
#define U16 unsigned int    /* unsigned 16 bits. */
