关于103VET6 驱动ili9320TFT的问题弄了一天要爆炸的感觉

首先，关于fsmc bank区我大概知道程序里怎么写取决与你的四根线怎么接 RS RD WR CS;
先说说我的吧。 stm32f103vet6 CS

D7 ---NE1 RS

D11---A16 WR

D5---NEW RD

D4---NOE 在定义内部基地址的时候，设定这样
#define LCD_REG *((volatile u16 *)0x64020000)

#define LCD_RAM *((volatile u16 *)0X64000000)

初始化FSMC的函数为、

FSMC_NORSRAMInitTypeDef FSMC_NORSRAMInitStructure;
FSMC_NORSRAMTimingInitTypeDef p;
RCC_AHBPeriphClockCmd(RCC_AHBPeriph_FSMC, ENABLE);

FSMC_NORSRAMInitStructure.FSMC_ReadWriteTimingStruct = &p;
FSMC_NORSRAMInitStructure.FSMC_WriteTimingStruct = &p;
FSMC_NORSRAMStructInit(&FSMC_NORSRAMInitStructure);

/* FSMC_Bank1_NORSRAM1 timing configuration */
p.FSMC_AddressSetupTime = 0; /*地址建立时间期限*/
p.FSMC_AddressHoldTime = 0; /*地址的持续时间*/
p.FSMC_DataSetupTime = 2; /*设定数据时间期限*/
p.FSMC_BusTurnAroundDuration = 0; /*总线转向时间*/
p.FSMC_CLKDivision = 0; /*CLK时钟输出信号的HCLK周期数表示时间???*/
p.FSMC_DataLatency = 0; /*指定在获得第一个数据前的时钟周期*/
p.FSMC_AccessMode = FSMC_AccessMode_A;

FSMC_NORSRAMInitStructure.FSMC_Bank = FSMC_Bank1_NORSRAM2; /*指定的FSMC块*/
FSMC_NORSRAMInitStructure.FSMC_DataAddressMux = FSMC_DataAddressMux_Disable; /*地址和数据值不复用的数据总线*/
FSMC_NORSRAMInitStructure.FSMC_MemoryType = FSMC_MemoryType_SRAM; /*外部存储器的类型*/
FSMC_NORSRAMInitStructure.FSMC_MemoryDataWidth = FSMC_MemoryDataWidth_16b; /*数据宽度*/
FSMC_NORSRAMInitStructure.FSMC_BurstAccessMode = FSMC_BurstAccessMode_Disable; /*禁用突发访问模式*/
FSMC_NORSRAMInitStructure.FSMC_WaitSignalPolarity = FSMC_WaitSignalPolarity_Low;/*指定等待信号的极性*/
FSMC_NORSRAMInitStructure.FSMC_WrapMode = FSMC_WrapMode_Disable; /*Enables or disables the Wrapped burst access mode for Flash*/
FSMC_NORSRAMInitStructure.FSMC_WaitSignalActive = FSMC_WaitSignalActive_BeforeWaitState;
FSMC_NORSRAMInitStructure.FSMC_WriteOperation = FSMC_WriteOperation_Enable; /*启用指定的FSMC块的写操作*/
FSMC_NORSRAMInitStructure.FSMC_WaitSignal = FSMC_WaitSignal_Disable;
FSMC_NORSRAMInitStructure.FSMC_ExtendedMode = FSMC_ExtendedMode_Enable; /*扩展模式*/
FSMC_NORSRAMInitStructure.FSMC_WriteBurst = FSMC_WriteBurst_Disable; /*禁用写突发操作*/
FSMC_NORSRAMInitStructure.FSMC_ReadWriteTimingStruct = &p;
FSMC_NORSRAMInitStructure.FSMC_WriteTimingStruct = &p;

FSMC_NORSRAMInit(&FSMC_NORSRAMInitStructure);

/* Enable FSMC Bank1_SRAM Bank */
FSMC_NORSRAMCmd(FSMC_Bank1_NORSRAM2, ENABLE);

哈哈，终于解决了。还是基地址设置的问题。现在的问题是  字符和文字是镜像的，我的是ili9328 怎么改初始化函数啊

但问题是 TFT根本没什么反应  而且如果fsmc初始化里的FSMC_Bank1_NORSRAM2改成FSMC_Bank1_NORSRAM1/3/4,程序就卡住，连while（1)都进不去。。测试的主函数为

  ili9320_Initializtion();  //TFT LCD彩色液晶屏初始化
ili9320_Clear(0x0645);
ili9320_PutChar(100,100,'a',Green,Blue);
  while (1)
{
GPIO_ResetBits(GPIOA,GPIO_Pin_5);
Delay(200);
GPIO_SetBits(GPIOA,GPIO_Pin_5);
Delay(200);

   }
去网上看了好多别人调试过程众说纷纭，试了很多，还是没有用，一个外部存储管理总线  怎么这么难用！！！
