*/ use_modes_pointer(); /*致使modes_pointer未初始化*/ } 那个程序员希望从if语句跳出,但他却忘记了break关键字实际上跳出最近的那层循环语句或者switch语句。现在它跳出了switch语句,执行了use_modes_pointer()函数。但必要的初始化工作并未完成,为将来程序的失败埋下了伏笔。 2.1.4 、意想不到的八进制 将...

4、 warning: passing argument 1 of ‘send’ makes pointer from integer without a cast 解释:函数send的第一个integer型参数没有强制转换为pointer型 5、warning: comparison is always true due to limited range of data type 解释:由于数据类型范围的限制,比较结果一直为真。
受组委会及灵动委托,逐飞科技针对第十七届智能汽车竞赛室外极速组的BLDC应用需求,精心设计了符合赛事需求的MM32 BLDC驱动开源方案供大家参考,该方案使用MM32SPIN360C,此单片机具有3个运放及3个比较器,无需外加运放与比较器。电机为内转子、2860Kv、电压为12V。开源项目
