买的是原子的电容屏, 采用的是NT35510驱动芯片, 我把FSMC读写的时序改小了一半, 用emWin的刷屏测试还是没有提高, 只有5568000 Pixels/sec
原来的时序:------------------------------------------------------------------------------------------------------------------------------
 readWriteTiming.FSMC_AddressSetupTime = 15;  
  readWriteTiming.FSMC_AddressHoldTime = 0x00; 
  readWriteTiming.FSMC_DataSetupTime = 60; 
  readWriteTiming.FSMC_BusTurnAroundDuration = 0x00;
  readWriteTiming.FSMC_CLKDivision = 0x00;
  readWriteTiming.FSMC_DataLatency = 0x00;
  readWriteTiming.FSMC_AccessMode = FSMC_AccessMode_A;  
   
writeTiming.FSMC_AddressSetupTime =9;       
  writeTiming.FSMC_AddressHoldTime = 0x00;  
  writeTiming.FSMC_DataSetupTime = 8;  
  writeTiming.FSMC_BusTurnAroundDuration = 0x00;
  writeTiming.FSMC_CLKDivision = 0x00;
  writeTiming.FSMC_DataLatency = 0x00;
  writeTiming.FSMC_AccessMode = FSMC_AccessMode_A;  

修改后的时序:**********************************************************************************
readWriteTiming.FSMC_AddressSetupTime = 5;  
  readWriteTiming.FSMC_AddressHoldTime = 0x00; 
  readWriteTiming.FSMC_DataSetupTime = 20;  
  readWriteTiming.FSMC_BusTurnAroundDuration = 0x00;
  readWriteTiming.FSMC_CLKDivision = 0x00;
  readWriteTiming.FSMC_DataLatency = 0x00;
  readWriteTiming.FSMC_AccessMode = FSMC_AccessMode_A;  
    
writeTiming.FSMC_AddressSetupTime =3;       
  writeTiming.FSMC_AddressHoldTime = 0x00;  
  writeTiming.FSMC_DataSetupTime = 2; 
  writeTiming.FSMC_BusTurnAroundDuration = 0x00;
  writeTiming.FSMC_CLKDivision = 0x00;
