Arduino Tutorial: Using the 3.2″ Color TFT display for Arduino from Banggood.com
Having a big Color TFT display for your Arduino Projects can make things much more impressive. Today I am going to show how to use the low cost 3.2″ inch Color TFT display with Arduino Mega and Arduino Due.
I always wanted to have a big display for my Arduino projects. So, a few weeks ago I decided to buy this 3.2 Inch color TFT display for Arduino Mega from Banggood.com because the price is so tempting! Less than 7$ for a 3.2’ color TFT display. With that price you can’t go wrong. Here’s the link.
WHERE TO BUY
1. 3.2” TFT Display: http://bit.ly/32COLORTFT
2. Arduino Due: http://bit.ly/ArduinoDUE
3. Arduino Mega:http://bit.ly/ArduinoMega
It is listed as a 3″ display but I measured it and it is 3.2″.
The display has a resolution of 480×320 pixels and has an SD card adapter on the back. I haven’t used SD card functionality so far. I will try to use it in the future. If you look carefully you can see that the display also uses a 3.3V regulator so it works fine with 5V and 3.3V logic levels.
As you can see the connection with an Arduino Mega board is extremely easy. All you have to do, is to plug the display in, and load the sketch. I have also loaded the demo sketch on the Arduino Due and as you can see it works fine on an Arduino Due as well. Arduino Due, is much faster than the Arduino Mega. The demo sketch needs around 44 seconds to run on the Arduino Mega, and only 22 seconds on the Arduino Due. That’s a huge performance difference. Now let’s go to the computer in order to see what drivers we need in order to use the display with Arduino.
The display uses the HX8357C controller. Unfortunately the UTFT library does not support it any more. I am using an older version of the library which supports the display. This version of the software is provided with the display.
Thank you very much Henning Karlsen for proving this library to the Arduino community!
