MSP430 LCD Display

Other Parts Discussed in Thread: MSP430F5438

Hi

I am looking for suitable LCD display to use with a MSP430F5438 preferably colour.
If anybody could recommend a good display to use with this device it would be much appreciated or possibly what to look for when choosing a display.

Thanks

Matt

    Just went through this whole ordeal myself, here are some things to look for before you choose:

    • Alphanumeric characters or just numbers?
    • Number of characters you can display?
    • Method of display (i.e.  7 Segment, Dot Matrix, ex....) ?
    • Number of IO to interface with it (Parallel / Serial input) ?
    • Whether or not you need and interface circuitry, such as BCD to 7SEG decoders

    Once you can answer all of those it should narrow down your search by quite a lot

    Keep in mind some of the fancier displays require a lot more data input to work, such as ones that use a dot matrix. They'll require a lot more data to be sent to display a character and they usually require some sort of font library in your code.

    Thanks for the reply

    The display is going to be used for displaying mainly text and some basic graphics.
    Looking for a display about 3-4” size, I have looked a this TFT display from Mikroe     http://www.mikroe.com/add-on-boards/display/tft-proto/
    They do supply driver libraries but only for PIC so am thinking this would be a lot of work to interface without any libraries?

    Thanks

    As soon as you go from plain text (or numbers) to graphics, it is unimportant whether it is simple or complex graphics. You need to handle the display with full dot-matrix resolution. There are display that provide an internal character generator ('drawing' the letters into the bitmap for you), but the cheaper ones won't. You need to handle the whole display as a large graphic in whcih you copy the letters or you r simple graphics.

    Size doesn't matter (*grin*). Resolution does. A 100" display with 64*128 pixels resolution is easier to handle than a 3" display with 640x480.

    If the library is available as source code, you only need to port the low-level communication. The high-level stuff (like printing text into tthe display) will likely work without (significant) modifications.
