Impossible to compile or verify the library #266

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 

 Everytime a try to compile or verify the program it shows an error:

 " 'u8g' was not declared in this scope "

 also it shows that:

"HelloWorld.ino: In function 'void draw()':
HelloWorld:117: error: 'u8g' was not declared in this scope
HelloWorld.ino: In function 'void setup()':
HelloWorld:131: error: 'u8g' was not declared in this scope
HelloWorld.ino: In function 'void loop()':
HelloWorld:147: error: 'u8g' was not declared in this scope"

 I don't know what the hell is happening but its impossible to compile with that errors, and a follow the right way of every step of the instalation...

Let me try to help but we need more info Arduino hardware and software version 
please.  The first error means you have not declared the object u8g.  Make sure 
you have created the object as global.

 Im using Arduino Mega 2560, and the lasted version of the IDE (Arduino 1.0.5).

 I do not think has anything wrong with the program... after all, its an example of the u8glib library.

 And yeah, i thought that too, but usually these examples are ready to compile, aren't they? I never changed them, all the programs that i took from others libraries and try to compiling works

Did you uncomment your device?

What do you mean?

The examples are incomplete. At the beginning of each example, there is a list 
of devices. You MUST uncomment your device and add/modify your pins.

 THANKS, actually the display i bought was with a wrong nomenclature, so i changed the pins and worked!
