菜鸟问个问题///GPIOC->ODR [复制链接]

英的板子，好久没弄了。汗。。

#define left          0x0001         // PE0 : left

===============================
if((GPIOE->IDR & left)==0)
      {
          delay(100);
        if((GPIOE->IDR & left)==0)
        {
        while(!(GPIOE->IDR & left) )
            {
            GPIOC->ODR=0x0000;
            }
        }         
      }
      GPIOC->ODR=0x0200;
===============================
单个按键么问题，但是如果我把摇杆其他的都放进去后，GPIOC->ODR相对应的修改，发现LED的灯位置会变化。

按LEFT，变成GPIO_Pin_7 的LED亮   ((u16)0x0080

这个问题，额，有人帮忙看下吗？

如果单独分开，一个个按键修改的话，没问题，一一对应。但放在一起，就会错位。

谢谢LS的。

还是C不过关啊。  ：（
