os_lcd.c

对pxa255内置lcd控制器编程来实现字符及图像的显示

extern void print_pic(char *);
extern void disable_lcd(void);
extern void enable_lcd(void);


extern void screen_clean(int);
extern char gImage_pic[];


void udelay(int multi)
{
  long int delay_1,delay_2;
  for (delay_2=0;delay_2<multi;delay_2++)
     for(delay_1=0;delay_1<100000;delay_1++);

}

void dummyOs()
{

 screen_clean(0x5);
 disable_lcd();
 print_pic(gImage_pic);      
 enable_lcd();
 udelay(300);
