I always feel that the title is ambiguous , For example, press the original key After loading , That is, if you press other after modification key Do not load into epprom, Always consider the wrong way to manipulate . The cleaning and judgment of all kinds of marks are really annoying . There are always some fine controls that need to be debugged , Maybe this is the level of a master .
