2、PB2Periph_AFIO, ENABLE;这里的 RCC_APB2Periph_AFIO, ENABLE 很容易忘记关于 FSMC开始看了点手册和别人的应用笔记大概把自己理解的记录下把 FSMC 与外围设备连接配置好后 就等于 FSMC 对于使用者屏蔽了对外围设备的 具体操作 只要向对应类型的映射地址空间内写入数据 这些数据 +地址就会自动 被翻译 (需设置相应时序的地址数据建立保持时间等参数 并写入外围存储设备在 FSMC 的角度来看 外围连接的存储设备被分为 ROMSRAMNOR - NAND Flash - PC Card等几种类型它们被对应为 FSMC 内 4个存储块 分别为64*

3、4mb(ROMSRAMNOR (6000 0000h - 6fff ffffh, (这一块又分为 4部分 每 一部分有片选信号 NE1:4可以连接 4片本类型设备使用 256mb(NAND Flash 1(7000 0000h - 7fff ffffh,256mb(NAND Flash 2(8000 0000h - 8fff ffffh ,256mb(PC Card(9000 0000h - 9fff ffffh例如下面程序中要使用的宏定义#define LCD_Command *(*(volatile u8 0x6c00 0000#define LCD_Data *(*(volatile u

4、8 0x6c00 0001 (LCD数据宽 度为 8BIT当数据写入 LCD_Command对应的地址时 地址和数据会分别被发送到对应的 AFIO 复用端口 将 AFIO 的 A0接至 LCD 的 C/D(Command/data脚 就自动切换了命 令和数据LCD_Command = 0x55; A0 = 0; 对应地址低位 0x6c00 0000LCD_Data = 0x55; A0 = 1; 对应地址低位 0x6c00 0001此开发板 LCD 与 MCU 的引脚对应关系为 :D0 - PD14 D4- PE7 A0 -PF00D1 - PD15 D5 -PE8 FSMC_NE4-PG12
