Comment/uncomment '#define USE_F_MACRO' in Menu.h
to switch between using Arduino F() macro or a noop replacement.
I told the menu to display free RAM for these tests, btw.
For testing PROGMEM support you would need the latest version with PROGMEM storage support.
Log message says "Switching PROGMEM for tests.".
(Yes I *do* know that this version reads progmem strings as char instead of unsigned char, breaking string display.
I don't care, should not influence the test.)
The numbers you get will differ by a few bytes, as the versions are not absolutely identical.
The "Testing using Arduino F() macro only. " commit has some additional functionality even.
RAM usage increases by 6 bytes when using the menu the very first time. I don't even know why.
I gave startup values for RAM usage.
