Step 1: Why We Need to Change Data Pins of the Screen Shield?

when we wan't to use more module like cc3000 wifi shield or any circuit need a interrupt pin (2-3)

we can't do that because this screen connected to pin 2 and 3 .

the library don't support changing data pins

To do that

1)download the original lib from this link:lib

2) install it

3)go to document/arduino/library/TFTLCD-Library-master/

4)open pin_magic.h

in this case we change LCD_D3 from D3 (in ard nano) to pin A3
