multiline display

[krzycho]

I need to make a mini terminal for the last 6-8 strings (FIFO) i tried to do it on multilines value display but i can't send correct strings with \n

Code:

      String L1 = "1 line";
      String L2 = "2 line";
      String str = String(L1 + '\n' + L2);
      sendValue(pin3, str);
      Serial.print(str);

Serial.print shows strings in two lines but multiline display shows nothing
