我用的是smt32F103V的100PIN,
以下是我的配置

LCD控制芯片是ili9331（和ili9320同类型，时序也一样），上面的配置有问题吗？
如果我直接读寄存器可以读到ili9331的ID，但写寄存器就没反应了。怎么个调试方法？

顶，做过fsmc的说下啊？
香主呢？

没有你的硬件连接图,不确认你那个结构体那样用能正常

复制

typedef struct

{

  vu16 LCD_REG;

  vu16 LCD_RAM;

} LCD_TypeDef;

#define LCD_BASE    ((u32)(0x60000000 | 0x00020000))

#define LCD         ((LCD_TypeDef *) LCD_BASE)

这样算
LCD_REG 的地址是0x60020000
LCD_RAM 的地址是0x60020002
不知道C/D是连接的地址线几?
