板子因为其它外设要用，所以没有用到自带的液晶控制器，是用fsmc驱动的，驱动ic是R61408,在F429上上同样的程序是可以驱动的，可是到了F7上就用不了了，

1. void MX_FMC_Init(void)
   
2. {
   
3.   FMC_NORSRAM_TimingTypeDef Timing;
   
4. 
   
5.   /** Perform the SRAM1 memory initialization sequence
   
6.   */
   
7.   hsram1.Instance = FMC_NORSRAM_DEVICE;
   
8.   hsram1.Extended = FMC_NORSRAM_EXTENDED_DEVICE;
   
9.   /* hsram1.Init */
   
10.   hsram1.Init.NSBank = FMC_NORSRAM_BANK1;
    
11.   hsram1.Init.DataAddressMux = FMC_DATA_ADDRESS_MUX_DISABLE;
    
12.   hsram1.Init.MemoryType = FMC_MEMORY_TYPE_SRAM;
    
13.   hsram1.Init.MemoryDataWidth = FMC_NORSRAM_MEM_BUS_WIDTH_16;
    
14.   hsram1.Init.BurstAccessMode = FMC_BURST_ACCESS_MODE_DISABLE;
    
15.   hsram1.Init.WaitSignalPolarity = FMC_WAIT_SIGNAL_POLARITY_LOW;
    
16.   hsram1.Init.WaitSignalActive = FMC_WAIT_TIMING_BEFORE_WS;
    
17.   hsram1.Init.WriteOperation = FMC_WRITE_OPERATION_ENABLE;
    
18.   hsram1.Init.WaitSignal = FMC_WAIT_SIGNAL_DISABLE;
    
19.   hsram1.Init.ExtendedMode = FMC_EXTENDED_MODE_DISABLE;
    
20.   hsram1.Init.AsynchronousWait = FMC_ASYNCHRONOUS_WAIT_DISABLE;
    
21.   hsram1.Init.WriteBurst = FMC_WRITE_BURST_DISABLE;
    
22.   hsram1.Init.ContinuousClock = FMC_CONTINUOUS_CLOCK_SYNC_ONLY;
    
23.   hsram1.Init.WriteFifo = FMC_WRITE_FIFO_DISABLE;
    
24.   hsram1.Init.PageSize = FMC_PAGE_SIZE_NONE;
    
25.   /* Timing */
    
26.   Timing.AddressSetupTime = 6;
    
27.   Timing.AddressHoldTime = 15;
    
28.   Timing.DataSetupTime = 9;
    
29.   Timing.BusTurnAroundDuration = 0;
    
30.   Timing.CLKDivision = 16;
    
31.   Timing.DataLatency = 17;
    
32.   Timing.AccessMode = FMC_ACCESS_MODE_A;
    
33.   /* ExtTiming */
    
34. 
    
35.   HAL_SRAM_Init(&hsram1, &Timing, NULL);
    
36. 
    
37. }

这个是fsmc配置，用的stm32cube初始化代码

1. #define Bank1_LCD_D    ((uint32_t)0x60020006)    //Disp Data ADDR//地址线是A16
   
2. #define Bank1_LCD_C    ((uint32_t)0x60000006)           //Disp Reg ADDR

我怀疑是不是这个地址不太一样
地址线是A16  同样的程序在F429上能用说明液晶初始化没问题，我怀疑是fsmc配置不正确或者地址不太对，所以求大家帮帮忙看一下 此帖出自小平头技术问答
