在我们生活中，我们很容易通过这个叫张三，那个叫李四，另外一个是王五；那是因为每个人有不同的名子，我们就很快认出，同样，对于要通过一个按键来识别每种不同的功能，我们给每个不同的功能模块用不同的ID号标识，这样，每按下一次按键，ID的值是不相同的，所以单片机就很容易识别不同功能的身份了。-In our lives, we can easily Zhang through this three or four叫李that, another five-Wang it is because everyone has a different name, we quickly identified, and similarly, for a button to pass to identify the different functions of each, we have different functions to each module" s ID number with different logo, so, for every one button press, ID is not the same value, so it is easy to identify the different single-chip function hats.
