Hi,

Have a look into the following link,
http://www.nxp.com/products/microcontrollers/cortex_m3/lpc1700/LPC1788FET208.html
may it help you for your MCU selection and touch screen interface.

Kind Regards,

There are a lot of touchscreens available :)

A simple solution is an SPI controlled LCD with SPI controlled touchscreen. That's doable with a simple LPC11C14 and enough for a simple small GUI.

See: http://www.watterott.com/en/MI0283QT-2-Adapter

If you expect more power, use something like LPC1788, especially this kit:

http://www.embeddedartists.com/products/kits/lpc1788_kit.php

That's a very powerful kit and able to use free Segger emWin :cool:

You can use it with a huge 7" :eek: touchscreen as shown here at TechCon 2011:

[B]Touch screen ... [/B]
Select an LCD display that comes with a touch screen controller, or use something like a TSC2046, that one is being used by Embedded Artists on a lot (if not all) of their boards.

[B]Linux[/B]

The LPCXpresso controllers that are being discussed in this forum are too small for Linux. If you want Linux I'd use one of the larger processors (lpc2478 or so).
Embedded Artists still have the lpc2468 Developer's kit (for uClinux) but there are also the LPC3141 board and the LPC3250 Developer's kit that runs 'real' Linux or if you are brave enough to create your own base board use the LPC3250 DIMM module.

But of course it all depends what you want to do.
