2.8" TFT Touch Screen

  • First of all, it's not MY code - it was borrowed from Arduino.
    Jazzed and LocalRoger did the work.

    As for the pins question, I believe that is correct.
    Those pins are being used as the data bus.

    The other definitions :

    all_pin_mask long %0000_0011_1111_1100
    all_ctl_mask long %0011_1111_1111_1100 '
    CS_BIT_MASK long %0000_0100_0000_0000 '$0400
    RS_BIT_MASK long %0000_1000_0000_0000 '$0800
    WR_BIT_MASK long %0001_0000_0000_0000 '$1000
    RD_BIT_MASK long %0010_0000_0000_0000 '$2000
  • Did someone mention ILI9341? obex.parallax.com/object/723

  • Okay, Mark_T.
    I saw your thread. Looks like you found the unicorn.

    This is a project that got started last year to see if we could port an application
    from Aurdino to Propeller.
    It's a 2.8" TFT touch screen from Radio Shack or Seeed Studio.
    Like this:
    seeedstudio.com/wiki/2.8''_TFT_Touch_Shield_V2.0
    Yeah. It uses the ILI9341

    The screen plugs directly into an ASC board (Martin Hodges' Arduino compatible Propeller board)
    We can't get the touch screen running on this platform because of some differences in the analog pins.

    But the display is up and running.
    A couple of the gurus here got it ported from Aurdino and coded some in PASM.
    I've played with it to learn how to use it some, and attached a couple of my tests.
    They do text in all four directions, and in three sized fonts.

    The Char and String routines need to be coded in PASM.
    The SPIN routines are working, but could be a lot faster.
    I've been trying to figure that out but haven't made much progress.

    So, what can you do with it?
    Anything actually useful?
