Hello, I am new in Platformio. I have to work with a project done by someone else, and there is some way to work that I don’t understand properly.
- In the file platformio.ini, there are these lines:
extra_configs = .env
I guess, but I am not sure, that this means that there is another file (.env, so without name only the extension) that has additional configurations and those configurations have the same use, if these configuration would be in platformio.ini file. Am I right?
- in the file .env there is a line wrote like this:
Do this means that is equivalent to use
#define EMERGENCY_MODE 1
What happens with the space, between “-D” and “EMERGENCY_MODE”? is it this space not necessary ? It is so simple like it do not have a space?
There is a doc/Web site where this is clarified?
or I am interpreting this in a wrong way, and DEMERGENCY_MODE is another variable/Constant/Macro than EMERGENCY_MODE?
- I tried changing the value to 0, so, like this:
But in another part of the program (consist in several files) is in the same situation like before I made the change. Also there is part of the program that work exactly like EMERGENCY_MODE has value=1, So the change I did, doesn’t make any change in the precompilator. And I did not found any file with the sentence “#define EMERGENCY_MODE 1”. Maybe it is a configuration problem and is not working properly, but first I must know if the way I am facing the logic is correct.
Could someone confirm, if my logic is correct?
Thanks in advance
