The main component of Me TFT LCD Screen module is a LCD display communicating with Makeblock Orion through serial port to show characters and graphics of different size and colors. The module is integrated with MCU and memory chip, and the Chinese characters, letters, and figures stored in the memory chip can be invoked easily through the serial port. Its blue/gray ID means that it has a double-digital signal port and needs to be connected to the port with blue or gray ID on Makeblock Orion.

Since the port of Me TFT LCD Screen has blue/gray ID, you need to connect the port with blue or gray ID on Makeblock Orion when using RJ25 port. Taking Makeblock Orion as example, you can connect to ports No. 5 as follows:

When the Dupont wire is used to connect the module to the Arduino UNO Baseboard, its TX and RX pins should be connected to TX and RX ports respectively as follows:

If you use Arduino to write a program, the library Makeblock-Library-master should be invoked to control the Me TFT LCD Screen. This program serves to display different graphics and characters through Arduino programming.

This module (Me TFT LCD Screen – 2.2 Inch) contains a voltage converter, an STM32 chip, and a serial flash memory of 2M. In contrast with other displays, it needs only serial port for communication, so it is easy to operate and connect.

A special serial port assistant is provided to help you set the baud rate of transmission, and store the processed pictures you want to display into the flash memory so as to implement the display or switch of boot pictures in your own project. To download pictures, you need other serial port for conversion. In addition, it also supports superposition of background pictures and the letters, and GUI display. Its applications include the calendar, voltage meter, ampere meter, etc.

Displaying a custom image or graphic on a LCD display is a very useful task as displays are now a premium way of providing feedback to users on any project. With this functionality, we can build projects that display our own logo, or display images that help users better understand a particular task the project is performing, providing an all-round improved User Experience (UX) for your Arduino or ESP8266 based project. Today’s tutorial will focus on how you can display graphics on most Arduino compatible displays.

The procedure described in this tutorial works with all color displays supported by Adafruit’s GFX library and also works for displays supported by the TFTLCD library from Adafruit with little modification. Some of the displays on which this procedure works include:

While these are the displays we have, and on which this tutorial was tested, we are confident it will work perfectly fine with most of the other Arduino compatible displays.

For each of the displays mentioned above, we have covered in past how to program and connect them to Arduino. You should check those tutorials, as they will give you the necessary background knowledge on how each of these displays works.

For this tutorial, we will use the 2.8″ ILI9325 TFT Display which offers a resolution of 320 x 340 pixels and we will display a bitmap image of a car.

As usual, each of the components listed above can be bought from the links attached to them. While having all of the displays listed above may be useful, you can use just one of them for this tutorial.

To demonstrate how things work, we will use the 2.8″ TFT Display. The 2.8″ TFT display comes as a shield which plugs directly into the Arduino UNO as shown in the image below.

Not all Arduino displays are available as shields, so when working with any of them, connect the display as you would when displaying text (we recommend following the detailed tutorial for the display type you use of the above list). This means no special connection is required to display graphics.

Before an image is displayed on any of the Arduino screens, it needs to be converted to a C compatible hex file and that can only happen when the image is in bitmap form. Thus, our first task is to create a bitmap version of the graphics to be displayed or convert the existing image to a bitmap file. There are several tools that can be used for creation/conversion of bitmap images including, Corel Draw and Paint.net, but for this tutorial, we will use the Paint.net.

The resolution of the graphics created should be smaller than the resolution of your display to ensure the graphics fit properly on the display. For this example, the resolution of the display is 320 x 340, thus the resolution of the graphics was set to195 x 146 pixels.

Image2Code is an easy-to-use, small Java utility to convert images into a byte array that can be used as a bitmap on displays that are compatible with the Adafruit-GFX or Adafruit TFTLCD (with little modification) library.

With this done, we are now ready to write the code. Do note that this procedure is the same for all kind of displays and all kind of graphics. Convert the graphics to a bitmap file and use the Img2code utility to convert it into a hex file which can then be used in your Arduino code.

To reduce the amount of code, and stress involved in displaying the graphics, we will use two wonderful libraries; The GFX library and the TFTLCD library from Adafruit.

The GFX library, among several other useful functions, has a function called drawBitmap(), which enables the display of a monochrome bitmap image on the display. This function allows the upload of monochrome only (single color) graphics, but this can be overcome by changing the color of the bitmap using some code.

The Adafruit libraries do not support all of the displays but there are several modifications of the libraries on the internet for more displays. If you are unable to find a modified version of the library suitable for your the display, all you need do is copy the code of the drawBitmap() function from the GFX library and paste it in the Arduino sketch for your project such that it becomes a user-defined function.

The first two are thex and y coordinates of a point on the screen where we want the image to be displayed. The next argument is the array in which the bitmap is loaded in our code, in this case, it will be the name of the car and the text array located in the graphics.c file. The next two arguments are the width and height of the bitmap in pixels, in other words, the resolution of the image. The last argument is the color of the bitmap, we can use any color we like. The bitmap data must be located in program memory since Arduino has a limited amount of RAM memory available.

As usual, we start writing the sketch by including the libraries required. For this procedure, we will use the TFTLCD library alone, since we are assuming you are using a display that is not supported by the GFX library.

Next, we specify the name of the graphics to be displayed; car and title. At this stage, you should have added the bit array for these two bitmaps in the graphics.c file and the file should be placed in the same folder as the Arduino sketch.

With that done, we proceed to the void loop function, under the loop function, we call the drawbitmap() function to display the car and the text bitmap using different colors.

The last section of the code is the drawBitmap function itself, as earlier mentioned, to use the drawbitmap() function with the Adafruit TFTLCD library, we need to copy the function’s code and paste into the Arduino sketch.

Plug in your screen as shown above. If you are using any other display, connect it as shown in the corresponding linked tutorial. With the schematics in place, connect the Arduino board to your PC and upload the code. Don’t forget the graphics file needs to be in the same folder as the Arduino sketch.

That’s it for this tutorial guys. The procedure is the same for all kinds of Arduino compatible displays. If you get stuck while trying to replicate this using any other display, feel free to reach out to me via the comment sections below.

To confirm, I had the T4 intermittently working on both the adafruit ili9341 library and the optimised ili9341_t3. I"ve been through 3 T4s and I have 5 different ILI934 displays. (all give the same results, pull ups, no pullups, removed sd circuitry, ran the T4 at 5v I"ve tried it all!)

Hi guys, welcome to today’s tutorial. Today, we will look on how to use the 1.8″ ST7735  colored TFT display with Arduino. The past few tutorials have been focused on how to use the Nokia 5110 LCD display extensively but there will be a time when we will need to use a colored display or something bigger with additional features, that’s where the 1.8″ ST7735 TFT display comes in.

The ST7735 TFT display is a 1.8″ display with a resolution of 128×160 pixels and can display a wide range of colors ( full 18-bit color, 262,144 shades!). The display uses the SPI protocol for communication and has its own pixel-addressable frame buffer which means it can be used with all kinds of microcontroller and you only need 4 i/o pins. To complement the display, it also comes with an SD card slot on which colored bitmaps can be loaded and easily displayed on the screen.

The schematics for this project is fairly easy as the only thing we will be connecting to the Arduino is the display. Connect the display to the Arduino as shown in the schematics below.

Due to variation in display pin out from different manufacturers and for clarity, the pin connection between the Arduino and the TFT display is mapped out below:

We will use two example sketches to demonstrate the use of the ST7735 TFT display. The first example is the lightweight TFT Display text example sketch from the Adafruit TFT examples. It can be accessed by going to examples -> TFT -> Arduino -> TFTDisplaytext. This example displays the analog value of pin A0 on the display. It is one of the easiest examples that can be used to demonstrate the ability of this display.

The second example is the graphics test example from the more capable and heavier Adafruit ST7735 Arduino library. I will explain this particular example as it features the use of the display for diverse purposes including the display of text and “animated” graphics. With the Adafruit ST7735 library installed, this example can be accessed by going to examples -> Adafruit ST7735 library -> graphics test.

Next, we move to the void setup function where we initialize the screen and call different test functions to display certain texts or images.  These functions can be edited to display what you want based on your project needs.

Uploading the code to the Arduino board brings a flash of different shapes and text with different colors on the display. I captured one and its shown in the image below.

That’s it for this tutorial guys, what interesting thing are you going to build with this display? Let’s get the conversation started. Feel free to reach me via the comment section if you have any questions as regards this project.

The DT022BTFT uses the same connections as the DT022CTFT, with the exception of the backlight (which has connections shown in the Displaytech datasheet).

The provided display driver example code is designed to work with Microchip, however it is generic enough to work with other micro-controllers. The code includes display reset sequence, initialization and example PutPixel() function. Keep the default values for all registers in the ILI9341, unless changed by the example code provided.

Note that the WR pin becomes the D/CX signal in serial mode. CS is used to initiate a data transfer by pulling it low. At the end of the data transfer, pull the CS pin high to complete the transaction. The timing diagram indicates that you can pull the CS pin high in between the command byte and data bytes within a transfer, but it is unlikely needed if the display is the only device on the SPI bus. To keep things simple, we suggest to leave it low during the entire transaction.

I got the 3.95" LCD from aliexpress which uses IL9488. I used the MCUFRIEND_kbv library. I am using an Arduino Mega as I need other GPIO to be used for other purposes. I can"t use the Uno because of this limitation.

I have other modules like the DS3231, and ESP8266 connected to the Mega and this 3.95" LCD connected as well. ESP8266 is powered separately using a 12-5V converted supply. The Mega is powered using another source. The normal graphics test is working in the LCD. I am able to make it work with the Nano, Uno and Mega. Even for the Mega I am able to write customized messages.

Every update (LCD display function is from the loop which sets the text when there is a second/time/hour difference in the time) seems like it draining more current as the one of the LED connected to Mega dims, the Rx/Tx LEDs also dim.

This is a 2.2” TFT LCD Display Module with an input voltage of 3.3V~5.5V, which is used to display colorful patterns and characters. The fastest screen refresh speed is about 256ms. The module is able to display multiple patterns in a cycle and realize dynamic display effect. At present, there are 19 common defined colors in the library, and users can also customize16-bit color codes. If we take the central point of the display as the origin of coordinates, the maximum absolute value of the positive and negative axis will be 64.

Note: the parameter “2.2 inches” is noted according to the Display Specification provided by the display manufacture, the real display area is about 1.26 inches (diameter: 32mm).

The new line of 3.5” TFT displays with IPS technology is now available! Three touchscreen options are available: capacitive, resistive, or without a touchscreen.
