TFT Touch Display Tutorial

In this Project, we will see about how to interface mcufriend 2.4" TFT Touch Display with Arduino.

Circuit Diagram:

Just Install TFT Touch Display Shield to Arduino

Steps to follow:

1) Interface Shield
     Interface the TFT Touch Display Shield in Your Arduino.
2) Library Installation
     Download and Install the three Libraries. Links are below.
3) Graphic Test
     Upload File > Examples > MCUFRIEND_kbv > graphictest_kbv.ino
     (Proceed to next step, if it is working good)
4) Touch Test
     Upload File > Examples > MCUFRIEND_kbv > Touch_shield_new.ino
     (If Paint works good, skip Calibration Step)
5)Calibration
     Upload File > Examples > MCUFRIEND_kbv > TouchScreen_Calibr_native.ino
     Open Serial Monitor, You'll receive calibration Values there.
     (Copy TFT ID, TFT pins, Calibration Values in Notepad)
6) Touch Test
     Upload File > Examples > MCUFRIEND_kbv > Touch_shield_new.ino
     (Change the Calibration Values and test it. If it works good, move to next step)
7) LED Test
     Connect an LED in Digital Pin 53 with 100 Ohm Resistor
     Upload File > Examples > MCUFRIEND_kbv > button_simple.ino
     (Add these 3 lines in appropriate place & Change Calibration Values)

Libraries Used:

1. MCUFRIEND_kbv - https://github.com/prenticedavid/MCUFRIEND_kbv

2. Adafruit-GFX-Library - https://github.com/adafruit/Adafruit-GFX-Library
