Trouble with "refreshAll" [SOLVED]

[Xavier Lopez]

Hello Fernando,

I have been reviewing and learning many things for several days thanks to your extensive and well documented code, however, and although it may seem strange, I have not been able to find out where the value of "refreshAll" is changed from "false" to "true" and vice versa.
Could you give me a clue?
Thank you and excuse my ignorance,

Hi!

Glad to hear!

Try search by (true) or (false) in all files.
The argument is passed in a function to say when the menu should be completely updated.

On setup you will find something like this:

Code: Select all

mainScreen(true);

Best regards.

I have noticed that the statement of the "refreshAll" argument is in the declaration of the functions although I still do not know where the change between "true" and "false" is decided, I suppose it will be with a timer.

Thank you and greetings

Hi!

The statement is passed as argument to a function.

Example:

Code: Select all

void mainScreen(bool refreshAll = false)

Here the variable refreshAll is declared as false by default.

This is a variable LOCAL it doesn't exists out of this function.

If you try change the value in some place of the code like this:

Code: Select all

refreshAll = true;

You will get a compiling error:

Variable refreshAll not declared in scope.

To change the value of this variable you should pass the value as argument.

Code: Select all

mainScreen(true);

Here you can see how it's used on code.
