Arduino DUE + CTE7 CPLD 7inch 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: https://bit.ly/1BEKo3V )
• 7inch CPLD + SDRAM TFT Touch Screen
• 2gb Micro SD Card

Here is the diagram of Connection and Pin:

Here is the INIT Code.

UTFT myGLCD(CPLD, 46, 47, 44, 45);
UTouch myTouch(40, 41, 42, 49, 38);
UTFT_SdRaw myFiles(&myGLCD);
