Other Parts Discussed in Thread: MSP430F5438A

Hi,

I want to interface a TFT Touchscreen LCD preferably 4.3" resistive with 65k colors to an MSP430F5438A for controlling my application. I am new to touchscreen interfaces. Can someone guide me with

  • The selection of  the lcd display , how it works and its availability in the market,
  • Its interface to msp as in what driver IC ,if required, is to be used
  • A sample code to control the LCD

    How an LCD works, how it is interfaced and what code to write in order to use it depends on the LCD you use. Almost no two LCDs are the same. The information you need should be in the LCD's datasheet.

    65k colors, resistive touchscreen and size are just three of the many parameters you should have on your list before looking for an LCD. And that's a job nobody can do for you.

    However, don't forget that filling/managing a matrix LCD (almost all touch display I know of are matrix displays) requires quite a lot ram. E.g. a 64x128 pixel display with 64k colors requires at least 16k ram for the image. Or a lot of clever (and likely slow and rather inefficient) code to handle the content.
