大家好，在原子哥的探索者LCD显示实验中，有一个小笔误。(注释中带?号的参数)
在LCD_Init()中，原代码为：
[mw_shl_code=c,true]
readWriteTiming.FSMC_AddressSetupTime = 0XF;  //?      //地址建立时间（ADDSET）为16个HCLK 1/168M=6ns*16=96ns        
readWriteTiming.FSMC_AddressHoldTime = 0x00;        //地址保持时间（ADDHLD）模式A未用到        
readWriteTiming.FSMC_DataSetupTime = 60; //?       //数据保存时间为60个HCLK        =6*60=360ns
readWriteTiming.FSMC_BusTurnAroundDuration = 0x00;
readWriteTiming.FSMC_CLKDivision = 0x00;
readWriteTiming.FSMC_DataLatency = 0x00;
readWriteTiming.FSMC_AccessMode = FSMC_AccessMode_A;        //模式A

writeTiming.FSMC_AddressSetupTime =9;        //地址建立时间（ADDSET）为9个HCLK =54ns
writeTiming.FSMC_AddressHoldTime = 0x00;        //地址保持时间（A        
writeTiming.FSMC_DataSetupTime =8;//?        //数据保存时间为6ns*9个HCLK=54ns
writeTiming.FSMC_BusTurnAroundDuration = 0x00;
writeTiming.FSMC_CLKDivision = 0x00;
writeTiming.FSMC_DataLatency = 0x00;
writeTiming.FSMC_AccessMode = FSMC_AccessMode_A;        //模式A
[/mw_shl_code]

似乎应该是：
[mw_shl_code=c,true]
readWriteTiming.FSMC_AddressSetupTime = 0x10; //地址建立时间（ADDSET）为16个HCLK 1/168M=6ns*16=96ns
readWriteTiming.FSMC_AddressHoldTime = 0x00; //地址保持时间（ADDHLD）模式A未用到
readWriteTiming.FSMC_DataSetupTime =0x3c; //数据保存时间为60个HCLK =6*60=360ns
readWriteTiming.FSMC_BusTurnAroundDuration = 0x00;
readWriteTiming.FSMC_CLKDivision = 0x00;
readWriteTiming.FSMC_DataLatency = 0x00;
readWriteTiming.FSMC_AccessMode = FSMC_AccessMode_A; //模式A

writeTiming.FSMC_AddressSetupTime =9;              //地址建立时间（ADDSET）为9个HCLK =54ns
writeTiming.FSMC_AddressHoldTime = 0x00;         //地址保持时间（A               
writeTiming.FSMC_DataSetupTime = 9;                 //数据保存时间为6ns*9个HCLK=54ns
writeTiming.FSMC_BusTurnAroundDuration = 0x00;
writeTiming.FSMC_CLKDivision = 0x00;
writeTiming.FSMC_DataLatency = 0x00;
writeTiming.FSMC_AccessMode = FSMC_AccessMode_A;         //模式A
