不是,是你定义了甚至赋值了,但没有代码读取它,通常是个警告,不应该是个错误。

1 上面的警告显示-Wunused-but-set-variable,意思就是变量没有被使用。要是我们不想看到这样的警告,则在编译中加入 –Wno-unused-but-set-variable即可。再来编译,就不会产生warning了。注意事项 gcc的这些警告本是为了帮助我们发现低级问题的,如果不让warning打印,那么必然要承担相应的风险,不过本文的这种warning...

定义了变量key,使用key的代码为:key = SPI2_ReadWriteByte(0x00);执行函数并将函数返回值赋值给key,没有使用这个返回。比如 int b=a;从a中读取数据负值给b.其实,我是感觉声明和负值的地方离那么远很奇怪。反正循环里面又不用,为什么不到负值的时候才声明。
