about gb.titleScreen

[Cerus33]

I try to ask in english :p

When i code gb.titleScreen(F("test"));
i had this message when i compile: 'F' was not declared in ths scope.
But when i see some exemple, i don't understand why, and when i code like this: gb.tittleScreen(("test")); it compile it.

what is the problem?

The F is because it is expecting a __FlashStringHelper, which basically means it ensures that the literal string is stored in Flash memory (the code space rather than the data space).

Do you have the correct includes when you use F()?

I see again and i think the problem is the logo i want display.

when i code: gb.titleScreen(F("test"), logo); it return error and whith no F, its good.
Perhaps it is the logo can't stored in flash memory ?

You should take a look at the gb.titleScreen page, it explains how it works. Can you compile the example?

In the examples the logo is stored in progmem because the "PROGMEM" keyword is used in the variable declaration:

Code: Select all

static unsigned char PROGMEM logo[]=

The macro F(" ") should be used only for inline text. You can't use it on variables.
