how to connect the TFT display

(ECTM4C1294xl) on which pins should I use

    Did you check that your display can work with 3V signals?
    Did you look at the display datasheet to see which pins need to be connected?
    Did you check that your display outputs 3V3 (as it shows a +5V pin, and you can NOT send a 5V signal into a TM4C129x)?
    Apparently this display has power connection as well as data (clock, chip select, miso, mosi). You need to figure out what type of communication your display requires.
    If you plan to use bit-bang control, then - provided that all electric requirements are ok - you can choose basically any GPIO, and deal with it in the software.

    Don't know this board/display, and the vendor's site seems down currently.

    However, judged by the few pins, it is serial (SPI) only.

    Not my favourite method, because:

    • most LCD chip provide no readback via serial interface
    • bandwidth is fairly limited

    Beside Bruno's concerns about the electrical interface, check out if this device fulfills your performance requirements.

    As a starter, investigate the fastest method to write to several pixel values (sequence of SPI writes), and calculate how long a screen fill will take.

    Would not a better (and more important) question be, "Why START with so demanding a display & interface?"

    "SIMPLE" starts build your knowledge, capability & experience.    Overly complex ones (TFT) achieve, "Pain/Suffering/Delay/Frustration!"

    A "nice" post appeared (right here) recently - suggesting FAR MORE SUITABLE Displays for a (clear) "first effort."

    A superficial web search brings up a lot of Arduino-related hits. That might explain the OP's idea, and even get him some code examples.
    But you are right - getting it running will most probably be troublesome, even with (Arduino) examples. And I expect an abysmal performance.

    Indeed f.m. - indeed.   Staff/I are (being entertained) watching ONE Large Character (painfully) draw upon an Arduino Controlled (word used lightly) TFT.   Second cup (hot chocolate) and the "top half" of that character (may) be (almost) recognizable.   (this w/the Ard. "cranked" - and running downhill...)

    Kilimanjaro IS there - emits a (strong) siren call - yet not all should heed/succumb to such clear, "Over Challenge."   (staff member here twisted her ankle climbing parking garage)
    As always - KISS rules - even though - and especially though - that direction appears (near) "banned here!"

    Swimming the English Channel "seems" easy! (right after I learn - How to swim...)

    Over-confidence and disregard of consequences is the prerogative of youth. (Not sure whom I'm paraphrasing here).
    That's why almost exclusively the youth is drafted for military/wars ...

    And - we may note - that was "my" fate...

    Mine too. In retrospect, I was quite naive then ...

    And my "fate" there could not be compared to Elvis' military service - rather dealing with an AK-47 copy than a guitar.

    BTW, since the OP seems still absent (or has abandoned this thread), we can go on indulging in digressions ...

    What "digressions?"

    Can - in ANY way - "How to connect to a (most unusual) TFT" - followed by (near) poster abandonment - qualify as deserving "rapt" attention & strict focus?

    Instead - you, Bruno, Robert & I all "chipped in" w/"more appropriate methods" all aimed at "Better Satisfying" a beginner's first efforts.
    Again - the fact that the mountain "looms large" proves improper justification for a poorly planned (i.e. unplanned) & unskilled "climb!"

    Perhaps we have scared the OP away with our "due diligence / KISS" comments.

    Seems not the first time that beginners are shocked when taking a first look behind the superficial Arduino front ...

    Should not his "unschooled purchase" of a (most likely) soon to be orphaned, overly complex display - have (rightly) achieved that?    NOT to be unkind - but really - KISS RULES!

    Such beginners must be taught, "Always watch the magician's, "Off Hand.""    (that's where the REAL action occurs...)
