stm32库里面有定义\x0d\x0a\x0d\x0atypedef signed __int64 int64_t;\x0d\x0atypedef unsigned __int64 uint64_t;\x0d\x0a所以你要定义64位变量直接用int64_t或者uint64_t定义就行，一个是有符号，一个是无符号
typedef unsigned int uint32_t; typedef unsigned __int64 uint64_t; 5、结构体用法 对于同类变量,以数组形式组合;不同类变量,以结构体形式组合。结构体的好处就是当以结构体作为自变量输入函数中,那么当结构体增删改查时,就不必修改函数的入口,方便易读。
