给出屏的初始化程序和M453 RTC的初始化设置，记得要打开RTC时钟
void InitLCD_ST7567(void)
{
FT12864_SDAT = FT12864_SCLK = FT12864_CD = FT12864_RST = FT12864_CS = 0;
//这里片选拉低后，就不再操作它了
delay_lcd(1000);
//待测此时间
//timer(30);//复位前的延时必须大于3ms
FT12864_RST = 1;
//timer(10);//复位完成后写入操作命令前的延时必须大于150ms
delay_lcd(1000*30);
//待测此时间，此时间应大于150ms
//0xE2
wlc(LCD_RESET);
//注意这里COM的输出要设置成反向 否则显示不对
