回复【3楼】正点妹子:
---------------------------------
LCD_REG/LCD_RAM这两个东西是定义了FSMC的相关地址变量，看#define LCD_BASE        ((u32)(0x6C000000 | 0x000007FE))
#define LCD             ((LCD_TypeDef *) LCD_BASE)这里就强制性转换成结构体的指针了，当你往LCD_REG送数据的时候就是往0x6C000000 | 0x000007FE这个地址上面放上数据，如同51上的P0 = 0XFF一样，仔细看下有关于STM32的FSMC的介绍吧

我的这样写的
#define LCD_REG_ADD           ((u32)(0x6c000000 | 0x000007fe)) //寄存器地址，命令,RS = 0
      #define LCD_DAT_ADD           ((u32)(0x6c000000 | 0x00000800)) //显示数据地址，显示RAM,RS = 1

      #define LCD_WR_REG(index)     ((*(__IO u16 *)(LCD_REG_ADD)) = ((u16)index))
                                    //写LCD寄存器写入数值index
      #define LCD_WR_Data(val)      ((*(__IO u16 *)(LCD_DAT_ADD)) = ((u16)val))
                                    //往LCD的RAM写入数据val
