int64_t result; result= ((rectime-oritime) + (tratime-destime))/2; 当((rectime-oritime) + (tratime-destime))是负数的时候,result不能得到正确的数,需要写成如下: uint64_t destime, oritime, rectime, tratime; int64_t result, tmp; tmp= ((rectime-oritime) + (tratime-destime));...

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
