一般英语的意思我想你也明白，"size_t"这个变量没有定义而使用了。定义这个变量问题可以解决。但是至于这个变量该怎么定义就只有你知道了。可以把源码发过来看看。我猜你是否是使用的库函数的方式编程。一般库函数为了更清楚的表达某些类型会把int型 typedef成size_t. 在linux下内核源码中这样的定义更是屡...

error:#20:identifier"TIM2_IRQChannel"isundefined谁能说说,哪里错了 你的固件库里的库文件没有添加进工程里面,所以出现未定义的情况。 TIM2_IRQChannel指定时器2的中断通道没有定义,其实在固件库对这些参数都有定义, 宏定义代替了一串寄存器地址数据。需要将.C文件添加到工程文件中 ...
