Hi everyone J here. Just wondering if someone can send me in the right direction. Im looking for an example program for a TFT I have, it's a 2.8" and it has a ST7781 Driver chip. I have it working on a Arduino UNO via Although it for a 2.4" in this example it works flawlessly on 2.8".

Has anyone got this TFT running on a UNO32. I have thought about Porting the code, but it will be a nightmare. I have had a look at UTFT for chipkit, but I'm not sure how to incorporate the LCD_D0 to LCD_D7 Pins See Picture [attachment=0]28-2.jpg[/attachment]

Any help, Flames :twisted: etc Appreciated. J. :mrgreen:

Damn, I was going to say use my TFT library but I don't have ST7781 in there yet, only ST7735.

Of course, you're welcome to fork it and add ST7781 support to it - it should just be a matter of copying the ST7735 and changing the init codes, screen size, etc.
