}I did not understand why you posted the original Arduino code without showing the code you were supposedly transcribing to C. Anyway, your next activity will now be to look in the compiler you want to work with, libraries that perform functions similar to those in Arduino and start the work by yourself, do not expect anyone to do it for you.
