And the string conversion of the code is relying on the synchronization state machine to achieve its control. In fact, string conversion circuit in the actual use of, or more, particularly in the area of communication lines and the decomposition of reuse, the principle is a string and the conversion and the conversion process and string. Here is a simple example, the computer serial port of the process of sending data, if sent to meet the conditions, but in fact is a process of conversion and a string. Well, do not talk nonsense, look at the code is.
