Other Parts Discussed in Thread: TM4C123GH6PM

Hi

Does anybody know a 7 inch or 9 inch LED panel with touch screen capability which it works with TM4C123GH6pm?

Thanks

    Hello Majid,

    What resolution are we speaking here for the 7" or 9", type of panel (serial, parallel, LIDD, Raster) and memory surely is not there on the TM4C123

    Some attention to detail is required - doubtful you meant "LED" panel (LCD) is (by far) the more usual.

    Such panels (that size) usually employ a parallel, bus driven controller - should you have any desire to update the screen with any fluency. TM4C123 and LX4F (may they rest in peace) strangely limited their ports to 8 bit - 16 bit transfers are far preferable - thus require 2 transfers via TM4C.

    To your quest - almost any panel can be made to work with any MCU. That said - certain MCUs make far better accommodations for high (and wide) data rate transfers than basic TM4C123 series. (i.e. TM4C129 series seems best suited for your LCD (not Led) desire...

    Hi Amit,

    I am thinking to use a LCD with 600*800 pixels and as a processor I am going to use TM4C129X microcontroller.

    Thanks

    Hello cb1,

    Or the more complicated method of storing an image on an external Flash (USB, MMC or SPIFLASH), reading it to a memory internally and using SPI bus to send to LCD panel with Buffer RAM. Clearly TM4C129 does that better.,

    Hello Amit,

    Indeed more complicated - and prepare to.....W......A......I......T.......for the fine SPI bus to transfer "5-6-5" pixel packed data to 480,000 (anxiously awaiting) pixels!

    There's a reason NO Tablet would use low end Cortex M4 (any maker) - nor would they drive a screen via SPI bus.... (or describe them as "Led..."

    Clearly he meant LED. I've had good results with this one: http://ameridroid.com/products/odroid-vu

    Mon ami - what's clear?  From your link:

    • Display: 9inch 1280 x 800 pixel TFT LCD

    And (even stronger) clarity - post's title, "LCD for Tiva C!"   Perhaps you "missed" that (rather critical) fact...

    The primary technology of small displays remains LCD although OLED has made great (frequently surpassing LCD) strides.

    LED describes one style of, "backlighting" such LCD displays (not required w/self-emitting OLED) yet the pixels (thus display) remain LCD.

    And that's quite clear!  (your incorrect & unjustified "LED" assertion - not so much!)    That said - David may join o.p. in, "Lack of attention to (LCD) not (LED) DETAIL!"
