Hello everyone,
I have successfully designed a code library to drive stepper motor in different control mode,
but i have a problem, what if in further projects i need to control more that one stepper motor.
Is there a method to convert this library to object like class in c# or c++. but i am using ANSI c

Thanks in advance

Solution 1

You could convert it to a C++ class, but if you need to use it from C, C++ and C# it is best to leave it as C. Accessing a C library from C++ is just the same as from ANSI C. Accessing from C# requires a little extra work[^], but is not too difficult.

I want to use it from c, but c is not OOP so is there a way to make it look like OOP
oop* object oriented programming
I want to treat this library as an object in C

Thanks,

No, C is a procedural language. And "making it look like OOP" will not provide any significant benefits.

ok, but how can i use this library as object in ANSI C, if that make any sense

Thanks,

You can't: C is a procedural language and has no concept of objects. If you want this as an object oriented library then you need to re-write it in C++. But, you would then need to provide a C-based interface for your ANSI C projects. As I said before, this is a lot of work for no significant benefit.

Solution 2

c code can you wrap in classes for c++. -> static functions.

The only way in c#: you can try to build a c-dll and call it from c#.

Good luck :-)

If you are controlling more than one motor, then converting your code to C++ will offer little benefit. You should be able to do this in C without much change.

Here are a few things for checklist:
- Make sure that your data is not stored in global and/or static variables/structures.
- Make all of your APIs pass around a context variable identifying which motor (etc.) is being controlled.

You don't need C++ or C# to do this. These languages will push you a little harder to do the right thing but you can do it all in C...
