构建一个嵌入式系统时，打印有时也会严重降低系统的效率，且说不定会使系统崩溃！这个代码将打印作为一个任务来实现，从而避免了打印过多导致系统崩溃或者效率降低！-build an embedded system, sometimes serious Print reduce the efficiency of the system, and maybe system will collapse! This code will print as a mandate to achieve, in order to avoid the excessive Print result in a system crash or reduce efficiency!
