新手编写LED程序

sjy7746

感觉程序没问题，可能是LED灯冲突了，导致颜色不对，绿色加蓝色=青色，然后加上红色就一直是青紫色闪啊闪...

这种问题如何解决？求各位大神指点。

int main(void)
{
while(1)
{
* (unsigned int *)0x40021018  |= ((1)<<3);
* (unsigned int *)0x40010C00  |= ((1)<<(4*0));
* (unsigned int *)0x40010C0C  &= ~(1<<0);
DelayMS()        ;
* (unsigned int *)0x40021018  |= ((1)<<3);
* (unsigned int *)0x40010C00  |= ((1)<<(4*0));
* (unsigned int *)0x40010C0C  |= (1<<0);
DelayMS()        ;
* (unsigned int *)0x40021018  |= ((1)<<3);
* (unsigned int *)0x40010C00  |= ((1)<<(4*1));
* (unsigned int *)0x40010C0C  &= ~(1<<0);
DelayMS()        ;
* (unsigned int *)0x40021018  |= ((1)<<3);
* (unsigned int *)0x40010C00  |= ((1)<<(4*1));
* (unsigned int *)0x40010C0C  |= (1<<0);
DelayMS()        ;
* (unsigned int *)0x40021018  |= ((1)<<3);
* (unsigned int *)0x40010C00  |= ((1)<<(4*5));
* (unsigned int *)0x40010C0C  &= ~(1<<0);
DelayMS()        ;
* (unsigned int *)0x40021018  |= ((1)<<3);
* (unsigned int *)0x40010C00  |= ((1)<<(4*5));
* (unsigned int *)0x40010C0C  |= (1<<0);
DelayMS()        ;
}
}

* (unsigned int *)0x40010C0C  |= (1<<0);    清0还写错了 &=~
我记得指南者的led是接在B0,B1,B5的
你所有的都是配置了ODR0 ，改成ODR1和ODR5

感谢指点！
昨天晚上看的野火直接利用寄存器来控制led闪烁，没有完全弄明白，做了后面的作业，ODR没有改变位置，所以导致冲突了。今天看了后面两课，总算了解了输出数据寄存器的作用。
