Estimating sketch size

Using Arduino Storage

Hi, is there any way to estimate the size of a program before writing it?

Only in the vaguest possible terms, like small, humongous, and "won't fit".

Now, with some idea what hardware you are interfacing with, and the requirements for the application, then the estimate can be made a bit more accurate.

If you are working with large arrays and so on -- yes -- to that extent.

Otherwise you have to do what I do -- I compile the code before I write it. That way I don't have to guess.

  1. experience^2 is needed
  2. if you use libraries with known size helps a lot
  3. usage of floating point adds approx 3-4K to your code. (is also a lib)
  4. the complexity of the algorithms needed
  5. the amount of storage (including temporary) needed
