    Hi sivaprasad,

    There is this, which includes a TFT LCD tutorial:

     Sample code for TFT is included on software package.

     To interface a specific LCD then more and more information are to be specified. I suggest you to buy a launchpad with LCD and try use the examples that come with them.

     Missing information:

     Launchpad type

     LCD type

     if multimode LCD than serial/parallel mode color depth..

     and so on all parameter of display/controller

    Thank you guys for your timely help and response,

    I have TM4C123G Launchpad and HY32D TFT LCD  based on SSD1289 display controller, how i can use the grlib for this purpose? is it possible to modify the sample code for this specific module?....

     Examples are based on that controller, otherwise other are using that controller and you can see schematic and code from them, try launchpad boosterpack page and see Robg or Dany Rebollo BP LCD.

    Wonder how you arrived @ that particular display?  Might a more mainstream (i.e. available, recent tech) TFT prove superior?

    Not all of your cost will be display, alone.  And - if that display proves an, "orphan" or difficult to purchase again - or in quantity - it's selection may be short-sighted.

    Enlightened display vendors provide an integrated "family" of displays - often a design for just "one" proves a design for many.  (sometimes, all!)  Undertaking such design once - rather than uniquely for each new requirement - appeals to many.  Perhaps warrants some consideration...

     I think as I got there by price selection or by ebay:

     having a pcb support the first time interfacing it is a good starting point when low cost boosterpack where not  available like now

    Agree with the advantage of pcb support - however what's, "one day there" @ ebay may not prove the case when you (later) return!  And - rarely do best/brightest displays (and tech support teams) wade ebay waters...

    Figures of merit for displays include; Contrast, Viewing Angle, Backlight brightness & presence/absence of Controller and/or "semi-standard" connector interface. 

    Too often -arts sourced in such manner - are orphans, overstocks, and/or have not proved successful in the "normal" market channels...

    The goal of, "Design Once" then Sell and produce (that initial design) in volume - steers toward more conventional sourcing methods...

     Hi CB1, when I selected this items it was ready to use with simple connection than made custom pcb, after that spare sample I got to conventional for mass production but remember for prototyping this assembly is a bargain.

     In case you wish do production number are good:

    • Model: HY32D
    • Shipping Weight: 60g
    • 592 Units in Stock
    • Manufactured by: HAOYU Electronic

     But I still prefer mass production from a good source ;)

    Thank you, Roberto.  We'll check the specs on this & report.

    We try to avoid, "Design/develop - then repeat" (for the same project...)   Investors (rightfully) scream!  (cb1 nightmare)
