string doesn't change

Hardware Arduino Due

PaulS:
If you change:

void loop() {

printOnDisplay("This is a test");
  while(1);
}



to

void loop()
{
  char test[] = "This is a test";
  printOnDisplay(test);
  while(1);
}



do you get the same (apparently incorrect) output?

With your change it now works as expected!
