Hello,

I found out this solution by myself with an experience that I gained in a bit complicated ways . I didn’t cross anybody else who had functioned this big screen by Arduino DUE before. Even in the forum only Graham (@ghlawrence2000) helped a bit. And at the end I succeed in transfering the display from an SD card to a screen by the DUE. Plus I achieved a speedy image change with a CPLD screen.

Arduino Ethernet Shield CTE7 CPLD 7inch Screen

You can find used libraries and Source Code and RAW image sample in the following link:

Or see all files in folder (Dropbox)

Here are the materials that I used

  • Arduino DUE
  • Arduino ethernet shield  (Pic: http://bit.ly/1BEKo3V)
  • 7inch CPLD + SDRAM TFT Touch Screen
  • 2gb Micro SD Card

Here is the diagram of Connection and Pin:

UTouch myTouch(40, 41, 42, 49, 38);
UTFT_SdRaw myFiles(&myGLCD);
