Draw texts on 2.8inch TFT Touch Shield using Arduino UNO

In the previous post, we saw the basics for getting started with 2.8inch TFT Touch Shield. Here, we will see the method for interfacing touch screen put over the display.

After completing the library adding procedures given in the previous step, copy TouchPanel.ino program to Arduino UI.

Compile and upload the program.

If uploading is successful, Your LCD display will be as shown below.

Touch the cross on the screen. Cross will move until the screen adjustment is completed. When the screen adjustment completes, your display will be as shown below.

Move your finger over the screen. A red line will follow your finger.

Following video will make the procedures more clear.

Getting Started with 2.8inch TFT Touch Shield using Arduino UNO

LCD displays are used to display pictures or other texts to get the status of devices or some other important information. Here, we will see the method of interfacing a 2.8inch TFT Touch Shield to Arduino UNO. A touch screen is also provided on the top of the display. Touch screen require some calibration and hence we will see the touch screen interfacing in the coming blogs. Steps for interfacing the display to Arduino UNO is given below.

Step 1 :

Assemble Arduino UNO and 2.8inch TFT Touch Shield.

Step 2 :

Connect Arduino UNO to computer.

Step 3 :

Download latest version of Arduino and source code of 2.8inch TFT Touch Shield.

Step 4 :

Extract both files.

Step 5 :

Copy and paste library files of 2.8inch TFT Touch Shield to Arduino libraries folder.

Step 6 :

Run Arduino. Copy and paste DisplayString.ino to Arduino UI.

Compile and upload code to Arduino UNO. String will be displayed if uploading is successful.

Step 7 :

Similarly, compile and upload DrawGraphic.ino to your Arduino UNO.

If uploading is successful, graphics will be displayed on the screen.
