background
There is a project that needs to use the library to encapsulate the code, leaving only the debugging interface for users to use and debug some parameters. In this way, the project looks simpler, and it is also convenient for customers to maintain.
There are also some usage scenarios where you need to encapsulate your own code. This is because you are afraid of being stolen by others, and your own efforts will be wasted. You can also provide it in the form of a library.
Of course, there are also the following scenarios
When a company or an individual needs to provide their own code for others to call, and you or the provider does not want to provide the source code (.c source code), only want to provide the header file.h (declare the function in the header file) for others When calling, others only need to know what the function of the called function is, what are the parameters passed, etc., and do not need to know how the function is implemented. At this time, a static link library is needed (of course, there is also a dynamic link library, here we first explain the generation and use of the static link library)
key step
Actual use effect
The routine I provide here is to use STC (Acrocrystalline) microcontroller to realize stc15w404as
This is also chosen by the customer, the principle is given, and only the code implementation is required.
The final actual library function call is 234.LIB
Add 234.LIB normally here, and the functions used are in the header file as follows
The code, the header file tells the client which parameters can be adjusted, and others cannot be moved
It is easy for customers, just need to understand a few macro definitions related to this header file.
