Okey, okey. Maybe I am confusing everyone. Lets keep it simple, right now I am using the hello world sketch which is something like this.
// include the library header
#include <glcd.h>
// include the Fonts
#include <fonts/allFonts.h>
void setup() {
// Initialize the GLCD
GLCD.Init();
// Select the font for the default text area
GLCD.SelectFont(System5x7);
GLCD.print("hello, world!");
}
void loop() {
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
GLCD.CursorTo(0, 1);
// print the number of seconds since reset:
GLCD.print(millis()/1000);
}
