I have one essential math function that I want to share with many subsets
I shall programming a coordinate function in arduino MEGA2560 and it shall have trigonometry function to share with about 15 same function in different purposes.
If you look at my earlier posts, you will observe that I shall building a home cockpit.
I think solution is the functions to modify integers outside setup and loop and rerun the trigonometry functions and modify memory address so each function shall go to correct integer to save bytes and might kilobytes. Maybe it is called inside assembly or something?
