This is modified TouchScreen library for TFT LCD Touch Screen Module Board For Arduino, like : http://www.ebay.fr/itm/2-4-inch-TFT-LCD-Touch-Screen-Module-Board-For-Arduino-UNO-NEW-LD-/141859601684?hash=item21077dbd14. It allows to operate the module that A2 and A3 pin shared between the TFT screen and the touch screen, without having to manually switch to pinMode(A2/A3, OUTPUT) after use touch screen for re-enable TFT screen.
The modified library is used in the same way as the base library (see example files). For display library, you can use Adafruit GFX Library and Adafruit TFTLCD-Library (see examples files for the configuration).
Warning ! If you use Arduino Mega board, use digital pins 22 through 29 for TFT digital pin, like :
| LCD PIN | ARDUINO PIN |
|---|---|
| LCD_D0 | 22 |
| LCD_D1 | 23 |
| LCD_D2 | 24 |
| LCD_D3 | 25 |
| LCD_D4 | 26 |
| LCD_D5 | 27 |
| LCD_D6 | 28 |
| LCD_D7 | 29 |
