SOLVED-BIG 7 inch TFT Looks great- 1 issue.

997_1:
If you use the UTFT library most questions can be answered by the associated documentation. Pins- depends on what functions you plan to use with the screen I.e. SD card, touch, flash, etc..
The above post require knowledge of how to modify code. Reading through these post, reading the documentation from the chip manufacturer, and reading other forums will allow you to get things started.
Best of luck.

I would just like to get the display working first....

I have the same screen and I have located the code parts that you have mentioned.

I have GND, 5v and 3v3 attached as mentioned

I have D0-D15 attached as mentioned which go to 22-37

I have then attached RS,CS,WR & RST as you stated in your opening post ie 38-41 with RD not connected.

I was just hoping that you might have missed something in your description as all I get is the backlight.
