问 程序再执行到一条语句的时候发生跑飞
不知道如何查找跑飞的原因
还能赐教跑飞出现的几个比较多的原因 答 1: 是汇编还是C语言？ 答 2: 是c语言啊
步知道怎么了 答 3: 可以贴出程序或发到zclierda.com 答 4: //**************************************************************************

} 答 6: 怎么发了两次
郁闷 答 7: 您发给我的只是工程文件，没有加载源文件。 答 8: 不好意思
已经重新发送了 答 9: 赵老师还能给我看看啊 答 10: ADC12CTL0 |= 0x01; // 开始转换
ADC12CTL0 &=~0x01;
删掉这句ADC12CTL0 &=~0x01。AD转换开启在AD转换完成之后会自动复位，
不需要进行关闭。 答 11: 告诉结果，期待中.... 答 12: 我试了一下，程序没有跑飞啊。 答 13: 没有跑飞正在验证是否可以实现自己需要的功能
感谢大家了 答 14: 赵老师还能告诉你是怎么试验的吗
