MCS-51单片机实用子程序库 的使用方法如下：



１．将子程序库全部内容链接在应用程序之后，统一编译即可。优点是简单方便，缺点是程序太长，大量无关子程序也包含在其中。

２．仅将子程序库中的有关部分内容链接在应用程序之后，统一编译即可。有些子程序需要调用一些低级子程序，这些低级子程序也应该包含在内。优点是程序紧凑，缺点是需要对子程序库进行仔细删节。-MCS-51 single-chip utility subroutine library subroutine library to use as follows: 1. Subroutine library will link all the contents in the application process, the compiler can be unified. Advantages of simplicity and convenience disadvantage procedures are too long, a large number of unrelated subroutines are included in one of. 2. Subroutine library only part of the contents of the relevant links in the application process, the compiler can be unified. Some subroutines required some low-level subroutine calls, these low-level subroutine should also be included. Procedures are the advantages of compact, disadvantage is the need to carefully abridged subroutine library.
