Deploy plain C-Code to Arduino Due

Hi!

What's the best way to deploy plain C-Code to the Arduino Due?

For my project, I'm generating Code from a Simulink-Model to a Visual Studio Project. Now I found Visual Micro, which works
pretty well, but everytime I generate code, I have to adapt the main-file to an .ino-file. Additionally I have to copy all the .c and .h-files from the C-Project into the Sketch-Project.
Is there an easier way to deploy a C-Project directly?

Thanks for helping!
