Howdy Everyone. I'm currently designing a project (around the Due) and need a display of some sort. I was looking at this one, or something like it, ITDB02-4.3 - ITEAD Wiki My question is, exactly how many of the Due's pins does it require (using the touch screen)? I know this should be a simple question, but I've searched for an hour and came up dry. Also, how much will this display "bog down" the Due compared to an 16x2 LCD?
Thank you all very much. Have a Great New Years!
If that is the type of display you are considering, then might I recommend this as an alternative?CTE 4.3" Display.
With that you should also get the shield. CTE DUE TFT/Touch/SD Shield
Touch requires 4 pins, SD requires 4 Pins, TFT requires 20 Pins.
How much does it bog down??
Simple text, you will not see any delay, it is very fast. Small images/icons very fast. If you wish to draw full screen images, that is when you will notice the delay! I have an 800480 display, and I have produced an updated/modified version of UTFT_TinyFAT which can draw full screen images from an SD card in approximately 620ms......... for an image 240240, about 130ms.
If all you have had until now is a 16x2 display, the extra possibilities will be incredible, SD / Touch, unlimited graphical options.... limitless fonts/sizes.
If you have not seen the UTFT library demo..... Watch this...UTFT / DUE Demo
Hope this helps.

Graham
Thank you very much Graham! That's just what I needed! I'm just going to have some text and some simple icons you can "click" on. Sounds like this should work good for my purposes. I love the flexibility and all the options with the TFT, hence I would really love to go that route. Though I've got a couple more questions for you if you have the time.
Just cause I'm curious, what is the difference between mine and the one you suggested? For the reason that I know what to look for in the future.
Is there anything special about there SD card mount? I've already got an SD card in this project, would it be possible to just use it for the display as well? Or vise-a-versa and use there SD card for some of my own stuff?
What would be the maximum cable length suggested for the display? For me a couple feet would be nice, but I read somewhere that someone had issues going over 200mm, but that could have been a different type of TFT display.
Thanks again,
Brad

If you looked at the link for the shield I suggested, the layout/format of the connector on the display you suggested would be awkward, the one I suggested sits nicely in the correct orientation.

It is just a neat all in one solution, since you already have SD, carry on with that.

I couldn't comment on this, since I only use my display with the shield mentioned, but the one comment I will make is, whenever anyone has problems, the answer generally includes something of the nature, 'keep your leads as short as possible'.
Hope this helps,
Graham
OK thanks again! The connector position makes sense, I was planning on running wires to it, so I didn't think of that. Now I'm thinking I'll plug it straight onto the Due, so I'll need to use your display.
Thank you for your time,
Brad
