求助，FSMC配置，用到FSMC_NE1和FSMC_A16时候，战舰中的代码怎么改？

原子大侠：
原来的是
#define LCD_BASE        ((u32)(0x6C000000 | 0x000007FE))
现在应该怎么改啊，我只知道0x6C000000改为0x60000000吧？后面怎么改？谢谢。

chinesehero

0x0001FFFE

1楼的是对的啊。

chinesehero

哦，那怎么屏不亮，看来得查查别的地方了？

回复【4楼】chinesehero:
---------------------------------
但是楼主位的0x6C000000是错的，应该是：0x60000000

chinesehero

是改成0x60000000，还是不能读取LCD ID
