改的这里#define LCD_BASE        ((u32)(0X60000000 | 0x0001FFFE))

还有
  FSMC_NORSRAMInitStructure.FSMC_Bank = FSMC_Bank1_NORSRAM1;
  FSMC_NORSRAMInitStructure.FSMC_DataAddressMux = FSMC_DataAddressMux_Disable; // 不复用数据地址
  FSMC_NORSRAMInitStructure.FSMC_MemoryType =FSMC_MemoryType_NOR;// FSMC_MemoryType_SRAM;  //SRAM   
  FSMC_NORSRAMInitStructure.FSMC_MemoryDataWidth = FSMC_MemoryDataWidth_16b;//存储器数据宽度为16bit   
  FSMC_NORSRAMInitStructure.FSMC_BurstAccessMode =FSMC_BurstAccessMode_Disable;// FSMC_BurstAccessMode_Disable;
  FSMC_NORSRAMInitStructure.FSMC_WaitSignalPolarity = FSMC_WaitSignalPolarity_Low;
        FSMC_NORSRAMInitStructure.FSMC_AsynchronousWait=FSMC_AsynchronousWait_Disable;
  FSMC_NORSRAMInitStructure.FSMC_WrapMode = FSMC_WrapMode_Disable;   
  FSMC_NORSRAMInitStructure.FSMC_WaitSignalActive = FSMC_WaitSignalActive_BeforeWaitState;  
  FSMC_NORSRAMInitStructure.FSMC_WriteOperation = FSMC_WriteOperation_Enable;        //  存储器写使能
  FSMC_NORSRAMInitStructure.FSMC_WaitSignal = FSMC_WaitSignal_Disable;   
  FSMC_NORSRAMInitStructure.FSMC_ExtendedMode = FSMC_ExtendedMode_Disable; // 读写使用不同的时序
  FSMC_NORSRAMInitStructure.FSMC_WriteBurst = FSMC_WriteBurst_Disable;
  FSMC_NORSRAMInitStructure.FSMC_ReadWriteTimingStruct = &readWriteTiming; //读写时序
  FSMC_NORSRAMInitStructure.FSMC_WriteTimingStruct = &writeTiming;  //写时序

QQ图片20190708112709.png 我们要用的板子上没有留出3.3和rest引脚。所有电源直接用5v可以吗？还有上电模拟电平复位。
现在问题是我屏幕只有白 {MOD}，没有字。只有断电了屏幕才不亮。连id都没读出。还需要改哪里
