2.8'' TFT Touch Shield v2.0

Introduction

enter image description here

This is a multifunctional Arduino/Seeeduino/Arduino Mega compatible resistive touch screen. It can be used as display device or sketch pad.Compared with the previous version, 2.8``TFT Touch Shield V1.0, we replaced the screen driver with a more professional chip, ILI9341 driver, providing different pin-saving SPI communication without sacrificing the data transmitting speed. Due to the communication method change, programs developed for the original version need modifications before being transplanted to the new version. With a SD card module integrated also on this shield, this shield reserves great room for other expansions to your project.

Features

  • Big screen for easy and comfortable experience
  • Backlight controllable via programming
  • 65k rich colors display
  • SPI pin-saving communication method
  • Full screen touch active range

Getting Started

Note

This getting started is based on Win10 and Arduino IDE 1.6.9

Here we will show you how this display work, we need thing as below to start.

Download Arduino Library

This library work for:

  • Arduino/Genuino UNO
  • Seeeduino V3/4.0/4.2
  • Arduino/Genuino Mega
  • Arduino Leonardo
  • Seeeduino Lite/Clio/Lotus
  • LinkIt ONE(Touch panel don’t work)

Click on the below button to download the library and install it (HOW TO INSTALL AN ARDUINO LIBRARY).

enter image description here

This library include few examples,

  • drawCircle
  • drawLines
  • drawNumber
  • drawRectangle
  • paint
  • shapes
  • text
  • tftbmp
  • tftbmp2

We use shapes example for this demo.

Connection and Upload the code

Insert the board to Seeeduino, and open your Arduino IDE. Click on File > Examples > TFT_Touch_Shield_V2-master > shapes to open the code.

Select the correct COM port and Boards(Seeeduino V4), upload the code to Seeeduino, then it’s done. If you have any question about how to start the uploading, please put had on here to get more details.

Backlight

The backlight is default on always, if you want to control the backlight, you need to do some hack in the board. Please look at the back side of the board, there’s a BACKLIGHT label, and one side named ON the other side named D7. We need to cut the wire at ON side and solder D7 side. As shown below.

enter image description here

Then you can control the backlight via control D7.

To open backlight: digitalWrite(7, HIGH);

To close backlight: digitaWrite(7, LOW);

Warning

Please be careful when use a box cutter and soldering iron.

Help us make it better

Thank you for choosing Seeed. A couple of months ago we initiated a project to improve our documentation system. What you are looking at now is the first edition of the new documentation system. Comparing to the old one, here is the progresses that we made:

  • Replaced the old documentation system with a new one that was developed from Mkdocs, a more widely used and cooler tool to develop documentation system.
  • Integrated the documentation system with our official website, now you can go to Bazaar and other section like Forum and Community more conveniently.
  • Reviewed and rewrote documents for hundreds of products for the system’s first edition, and will continue migrate documents from old wiki to the new one.

An easy-to-use instruction is as important as the product itself. We are expecting this new system will improve your experience when using Seeed’s products. However since this is the first edition, there are still many things need to improve, if you have any suggestions or findings, you are most welcome to submit the amended version as our contributor(Please refer to the tutotrial How to edit a document) or give us suggestions in the survey below, Please don’t forget to leave your email address so that we can reply.

Happy hacking
