地址/数据复用使能

YZM

战舰版  手册中参数 FSMC_DataAddressMux 用来设置地址/数据复用使能，若设置为使能，那么地址的低 16
位和数据将共用数据总线，仅对 NOR 和 PSRAM 有效，所以我们设置为默认值不复用，值
FSMC_DataAddressMux_Disable。但程序里384行：FSMC_NORSRAMInitStruct->FSMC_DataAddressMux = FSMC_DataAddressMux_Enable;

我看错了？还是别处另有设置

正点原子

最新代码是这样的:

[mw_shl_code=c,true] FSMC_NORSRAMInitStructure.FSMC_Bank = FSMC_Bank1_NORSRAM4;// 这里我们使用NE4 ，也就对应BTCR[6],[7]。 FSMC_NORSRAMInitStructure.FSMC_DataAddressMux = FSMC_DataAddressMux_Disable; // 不复用数据地址 FSMC_NORSRAMInitStructure.FSMC_MemoryType =FSMC_MemoryType_SRAM;// 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_Enable; // 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[/mw_shl_code]
