But the key is sensing automatically without touching

    Carefully study all the documentation, application notes, guidance, examples, etc from the screen manufacturer/supplier

    Double-check that you have completely & correctly applied all that information

    If you're still having problems, contact screen manufacturer/supplier for support - it has nothing to do with Keil or ARM.
