I have a similar question as posted ages ago here (without answers): http://arduino.cc/forum/index.php/topic,20138.0.html
I am trying to use the Mega Ethernet Shield and a 3.2" TFT LCD with touch screen and SD card reader. According to the documentation, the SD Card PINS that comes with the LCD are conflicting with some pins on the Ethernet shield. In addition, I am using ITDB02_Touch and UTFT libraries from http://www.henningkarlsen.com/electronics.
Also, everything works well separately. I mean, I can browse the ethernet pages and touch the screen. However, after I first touch in the screen the ethernet becomes unresponsive.
I don't really need the SD card and as far as I can see in the code the SD isn't being activated, unless I implicit activate it.
Any thoughts on how to use both Ethernet and touch screen together?
Thanks, Franklin Dattein
