I'm getting into Visual interfacing with my AVR projects and I am selecting a Touch screen to prototype with.

So far I have narrowed it down to 2 different ones that are within my price range.

The TouchShield Slide , which I could use with an AVR running the Arduino software and bootloader, seems simple to use but whimmpy
- OR -
The ezLCD-103 which seems a bit more "robust and powerful" than the other.

If you have used either;
1. Whats your opionion, which would you recommend for an advanced newbe?
2. Ease of use/intergration to an AVR or Arduino?

Any other recomendations?

Thanks[/list]

This one is sweet and inexpensive!

I haven't tried it myself, perhaps for my next project.

Thanks but that screen doesn't come with any control circuitry, probably why it's cheaper.

Yes it does, you can read from the webpage:

The display also has an integrated SSD2119 or compatible display controller

You can interface the display with your micro using SPI or a 18/16/9/8 bit parallel interface.

I am thinking of playing around with them too. Are there any in the $20-30 range?

I went with the ezLCD+103, and I am glad I did.
It has every thing built on board + a ATMEGA164P chip on the Earth_IO carrier board that can be programed, SD card, and temp sensor.

It has almost 4 megs of ram for storing bitmaps and fonts. It also has it's own programing Lang for drawing objects, displaying bmps and creating buttons, so all I basically need to do is send it data to display. It also has spar pins that can be configured as IO pins - great for Hard button options or ON/OFF style inputs. The Earth_IO board has 7 ADC inputs.

I may even work on a proto shield so it can attach to the Arduino. It can take external commands in Lowe of it's own programing Lang.

These were taken with my cell phone so not the greatest, but you can see what I have done in just a few hours - and it's not even connected to my AVR yet. the second picture is the ezEarth_IO board, that I may or maynot use.

What I meant there was that you have to connect the 50 pin ribbon to the AVR and other circuitry, as well as the 4pin resistive touch screen. it's not exactly plug and play.
