需要注意的是在标准库中和在HAL库中FSMC的配置有不小的不同，首先是FSMC相关结构体和标准库中不同，有一些在标准库中可以配置的选项在HAL库中并不存在，还有FSMC配置完成后初始化FSMC的函数和标准库中也有很大不同，如果使用了两个FSMC_NORSRAM_TimingTypeDef，则要使用HAL_SRAM_Init()函数进行初始化。还需要注意的是要使能BANK1。

修改复位函数

还有其他一些修改，改动不大

rebuild工程，如果没有错误，在main函数中调用LCD初始化函数，就可以直接使用标准库中可以使用的绘制函数了。

修改后在main函数中使用绘图函数时要注释掉原有的GPIO和FSMC初始化函数。

修改后即可以在STM32CubeMX中配置后就可以将之前修改好的文件直接添加到工程中使用，这样即可在LCD上显示其他功能的状态信息。
