Okay, so i'm dropping combining graphics with m2tklib, but, how can i make a status screen then?
I would say this: M2tklib is a strong library to enter data and menus. It is not a perfect solution to display something. If you only need to display something, you do not need M2tklib.
What about this: Make a list of all the sensor values you want to display. Combine these value onto groups which fit on one graphics pages. Maybe you will end up with 3 different pages of sensor values.
Initially you will display page 1. If the user presses a button, then display page 2. Another button press, display page 3. With one more button press, page 1 again will be visible.
Still you can combine this with M2tklib. A second button will bring you to M2tklib. For example if you want to display the time, then it might be required, that the user enters the time zone. This could be handled by m2tklib. Once this information is given from the user, m2tklib can jump back to the sensor pages.
