求助，Cube生成的fsmc代码为何没有IO初始化代码？难道不需...

问答
是否解决:

如题，使用Cube V4.11生成的fsmc代码里，只有FSMC的初始化代码，却没有GPIO初始化代码？难道不需要再对GPIO进行初始化？
生成的SDIO的初始化代码也是一样，也都没有GPIO的初始化代码，记得以前用标准库的时候都是需要对GPIO配置的....求解答！

HAL_FSMC_MspDeInit() 你搜索这个函数就出来了.

莫非它不在需要配置GPIO？只要初始化FSMC，单片机会自动配置GPIO？亦或者，HAL库在自己的某个角落里已经配置好了GPIO，可是我也没找到...
再或者，需要使用者自己写GPIO的初始化代码，那感脚太不智能了.....

用过的朋友们，给科普一下！谢谢：）

谢谢啊，终于解了我的疑惑，真的是看的不仔细啊，还是很智能的，得好好学习一下HAL

再请教一下，是不是直接用我面贴的代码就无需初始化GPIO了？
刚才搜了一下你说的那个函数，确实找到了初始化的代码，但逐级“追踪”，却没看出来那个函数调用了它...

HAL_FSMC_MspDeInit（）上级是HAL_SRAM_MspDeInit（），
HAL_SRAM_MspDeInit（）的上级是HAL_SRAM_DeInit（）
可是没看到那个函数调用了HAL_SRAM_DeInit（）....

难道需要使用者手动调一下HAL_SRAM_DeInit（）？
