Global variable usage

When I select Verify to check my code, the Global variable usage value does not seem to change even though I know I added over 100 bytes with a new variable. I am using version 1.1.13 and Windows 10.

Any ideas?

the compiler is pretty good in optimization. E.g. if you don't use the variable in your sketch, it will not take any SRAM.

As always:
show your code or make a demo sketch showing your findings to get a better answer.

Hi noiasca,

Thanks for the "heads up." They are used in an ISR and I have not yet written the code in "loop" which accesses them. Making them volatile solved my issue.
