- // All the mcufriend.com UNO shields have the same pinout.
- // i.e. control pins A0-A4. Data D2-D9. microSD D10-D13.
- // Touchscreens are normally A1, A2, D7, D6 but the order varies
- //
- // This demo should work with most Adafruit TFT libraries

- #define LCD_CD A2 // Command/Data goes to Analog 2
- #define LCD_WR A1 // LCD Write goes to Analog 1
- #define LCD_RD A0 // LCD Read goes to Analog 0
- #define LCD_RESET A4 // Can alternately just connect to Arduino's reset pin
