Integration in STM32 microcontroller

[DanielSSolid360]

Hi, I'm trying to integrate your libosdp library into my STM32 following your C example, but it's not working. The linker is missing some functions (such as osdp_cp_setup) that are actually defined in files like osdp_cp.c, where other headers like module.h or utils are called, which in turn use other libraries or functions outside the scope of an STM32. So, is it even feasible to integrate this library into an STM32 microcontroller, or am I wasting my time?

Additional info: My keil uVision project is built using the ARM 6.16 compiler, which might be the reason I have issues trying to integrate this since it has a propietary LLVM/Clang compiler and it's own linker.

Hello @DanielSSolid360 It is certainly possible and a port for STM32 has been reported working before. Have you see other threads that discuss porting? such as this and this?

It is not enough to compile the example alone. You'd need to build LibOSDP for your target first and then link it to the example. If you do not want to do this, you could use something like PlatformIO/vcpkg where LibOSDP is already ported.

I'm not just compiling the example. I'm trying to integrate the library into my Keil uVision project. However, some of the dependencies used by the library are causing linker issues (I have also included the utils headers and C files). Perhaps I'm not properly building the library within my Keil uVision project. I'll take a look at those two closed issues but considering how many changes performed the user vk2tds to make work with arduino it might be necessary to also perform additional changes in order to be able to integrate it within my keil project, unless I'm missing something else.
Thanks for your time.

Hi again,
I need to resolve this issue as we need it for one of our company's projects. I have posted a project on freelancer with more details about my case and payment. If you are interested you can contact me there or to my company email: [email protected]

Arduino is a different story. It's just a poorly designed platform which does not account for advanced users trying to do advanced things. It makes far too many assumptions about the code/project and how it has to be structured to the point where it was impossible for me to help @vk2tds in any meaningful way. So I gave up and added support for PlatformIO which is a much better designed platform, to which porting LibOSDP was a breeze.

Since then my recommendation for Aruino users who wish to use this project (including @vk2tds), is to consume it from PlatformIO.

This shouln't be an issue so long as the C compiler works. LibOSDP does not have any special requirements in the way it is built or linked.
