Arduino DUE + CTE7 CPLD 7″ Screen + Ethernet Shield + Load Image From SD

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.

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

• Source Code
• Used Libraries (UTFT, UTouch, sd, sd_raw etc..)
• RAW image sample for sd card

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:
