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/
in this case we change LCD_D3 from D3 (in ard nano) to pin A3
Step 2: Download
