| Apr 23, 2020 at 18:22 | comment | added | blackdaw | @KIIV You are right. I picked up many misconceptions through "beginner guides". The one you linked is a very helpful guide, thank you! | |
| Apr 23, 2020 at 17:26 | comment | added | KIIV | @blackdaw I'm pretty sure it's about declaration and definition of Class methods, not variables. And non rules/myths: Don't insist that all declarations shoudl be at the top of function and two rules Don't introduce a variable (or constant) before you need to use it | |
| Apr 23, 2020 at 17:13 | comment | added | blackdaw | @KIIV , concerning C++ I've read many times that separate declaration and definition can be part of "good practice". Your explanation was never mentioned but seems to make sense! Maybe it makes no difference with (aggressive) compiler optimization? | |

@EdgarBonet , it compiles and uploads but will not execute Setup(). Setup() starts with Serial.begin(9600); Serial.println("test"); Blinking the builtin-led doesn't work either.

Actually, DateTime now = rtc.now() might have utilize "copy elision", so it gets constructed directly into now variable and therefore it's faster than your approach (as you effectively blocked this possibility - so it has to create temporary object and copy it into now variable).

Re "I CAN NOT declare DateTime now; in global scope": what happens if you do so? A compilation error? Incorrect run-time behavior? I tried and it compiles just fine (but I have no RTC for testing).

Need for static specified ; can't declare in global scope
