arduino 3.5 tft display ili9481 brands

Displays are one of the best ways to provide feedback to users of a particular device or project and often the bigger the display, the better. For today’s tutorial, we will look on how to use the relatively big, low cost, ILI9481 based, 3.5″ Color TFT display with Arduino.

This 3.5″ color TFT display as mentioned above, is based on the ILI9481 TFT display driver. The module offers a resolution of 480×320 pixels and comes with an SD card slot through which an SD card loaded with graphics and UI can be attached to the display. The module is also pre-soldered with pins for easy mount (like a shield) on either of the Arduino Mega and Uno, which is nice since there are not many big TFT displays that work with the Arduino Uno.

The module is compatible with either of the Arduino Uno or the Arduino Mega, so feel free to choose between them or test with both. As usual, these components can be bought via the links attached to them.

One of the good things about this module is the ease with which it can be connected to either of the Arduino Mega or Uno. For this tutorial, we will use the Arduino Uno, since the module comes as a shield with pins soldered to match the Uno’s pinout. All we need to do is snap it onto the top of the Arduino Uno as shown in the image below, thus no wiring required.

This ease of using the module mentioned above is, however, one of the few downsides of the display. If we do not use the attached SD card slot, we will be left with 6 digital and one analog pin as the module use the majority of the Arduino pins. When we use the SD card part of the display, we will be left with just 2 digital and one analog pin which at times limits the kind of project in which we can use this display. This is one of the reasons while the compatibility of this display with the Arduino Mega is such a good news, as the “Mega” offers more digital and analog pins to work with, so when you need extra pins, and size is not an issue, use the Mega.

To easily write code to use this display, we will use the GFX and TFT LCD libraries from “Adafruit” which can be downloaded here. With the library installed we can easily navigate through the examples that come with it and upload them to our setup to see the display in action. By studying these examples, one could easily learn how to use this display. However, I have compiled some of the most important functions for the display of text and graphics into an Arduino sketch for the sake of this tutorial. The complete sketch is attached in a zip file under the download section of this tutorial.

As usual, we will do a quick run through of the code and we start by including the libraries which we will use for the project, in this case, the Adafruit GFX and TFT LCD libraries.

With this done, the Void Setup() function is next. We start the function by issuing atft.reset() command to reset the LCD to default configurations. Next, we specify the type of the LCD we are using via the LCD.begin function and set the rotation of the TFT as desired. We proceed to fill the screen with different colors and display different kind of text using diverse color (via the tft.SetTextColor() function) and font size (via the tft.setTextSize() function).

Next is the void loop() function. Here we basically create a UI to display the youtube subscribe button, using some of the same functions we used under the void setup() function.

The Adafruit library helps reduce the amount of work one needs to do while developing the code for this display, leaving the quality of the user interface to the limitations of the creativity and imagination of the person writing the code.

I have posted a brand new TFT_HX8357_Due library for the Due on my GitHub repository. The display supported by the library is 16 bit with 480 x 320 pixels and is available at low cost from a number of sources for example from Banggood:

Performance is quite good (320x240 UTFT demo completes in less than 1.4s) despite the fact that the 16 bit bus to the TFT is mapped to 4 different ports and pretty random processor register bits, so a lot of register bit juggling has to be performed that wastes time.

Sometimes the vendors supply a different controller, probably an ILI9481, even though the advert states HX8357B, so the library also supports that controller by selecting the ILI9481 driver in the User_Setup.h file within the library.

This 3.5 inch TFT LCD Module can be can be easy controlled by MCU such as 8051, PIC, AVR, ARDUINO, and ARM .It can be used in any embedded systems which require display high quality colorful image. Please see the sample pictures, they are taken directly from the LCD display. The Module include a 5V>3.3V regulator, touchpad IC, PWM circuit and SD card slot.

This 3.5 inch TFT LCD Module is not an ordinary 3.5 inch Module, this module has a high resolution of 480x320, Ordinary 3.2 inch has only 320x240 resolution. This module has an double resolution and extremely fine dot pitch (0.139mmx0.139mm). It also include a touchpad and 12bit onboard touchpad controller. This LCD module is suitable for user require high resolution, brilliant display quality.

The TFT LCD Module has embedded Flash IC, which contain fonts of 10 sizes and 236 icons. The LCD module support Henning Karlsen"s UTFT library, which can be downloaded here.
