Note: The following picture is the connection diagram of the 2.8-inch TFT screen and Arduino uno, but this product is connected in exactly the same way.

This product uses the same LCD control chip and touch panel control chip as the 3.5-inch TFT screen of the same series of our company, so the code is completely compatible. The following takes 3.5-inch TFT as an example to introduce.

LCD_Show can display colorful patterns with different shapes and times. LCD_ShowBMP is for displaying the picture in BMP, and LCD_Touch is for using the touching function.

The display controller used in this product is ILI9486, and we need to initialize the controller through the SPI communication protocol, and the initialization functions are written in LCD_Driver.cpp.

The function functions related to the screen display are written in LCD_GUI.cpp. The function of each function and the parameters passed are explained in the source code. You can call it directly when you need to use it.

Before using LCD_ShowBMP to display pictures, first copy the pictures in the PIC folder in the data to the root directory of the SD card (you should understand that in the root directory, that is to save the pictures directly to the SD card, do not put them in any subfolders folder.).

These functions are all written in LCD_Bmp.cpp. In fact, the image data in BMP format with a specific file name is read from the SD card, and then the display function written by us is called to re-express the data as an image.

In fact, you can also use Image2Lcd image modulo software to convert images of different sizes and formats into array data, and then use the functions we wrote to display them.

The data sheets of all control chips are given in the information for your reference. If you want to know more about why the underlying functions are written like this, go to the data sheets and look at them!

The demo has been tested on XNUCLEO-F103RB, just insert XNUCLEO-F103RB as shown below. The model of XNUCLEO-F103RB is STM32F103RBT6. If you need to port the program, please connect it according to the actual pin and the schematic diagram.

Note: The following picture is the connection diagram of the 2.8-inch TFT screen and XNUCLEO-F103RB, but this product is connected in exactly the same way.

The demos are developed based on the HAL library. Download the program, find the STM32 program file directory, and open STM32\XNUCLEO-F103RB\lcd4in-demo\MDK-ARM\ lcd4in-demo.uvprojx.

Before using LCD_ShowBMP to display pictures, copy the pictures in the PIC folder in the data to the root directory of the SD card, and then insert the SD card into the SD card slot on the back of the screen to start the download program verification.

I have already searched through this forum but I found out most of the 2.8"" TFT LCD problems discussed here are based on the one with a breakout board module, which can be directly plugged into Arduino UNO. While the screen I got has 34 pins, 17x2.

as a guide to interface the screen with Arduino UNO. I find out that the screen shown in the link actually has slightly different pins compare to the one I bought (Because the one is for 2.4"" TFT LCD I guess?).

So, anyone has deal with this kind of 2.8"" touch screen before? What is the exact connection on this? And also on my screen, the pins MISO, MOSI, CLK, T_CS, PEN, F_CS are left unconnected.

My first post back from hiatus talked about how I was getting into hardware components and programming them. Although I’ve had both hardware and software experience, the experience of producing home-grown hardware/software solutions is something new to me. It is very fascinating though and I am absolutely gitty about it… just ask my coworkers. I can’t shut up about it.

As you may have read in the previous post, after careful consideration I ordered up a bunch of hardware. For the sake of this article, however, only two items will be important from that list. They are the Seeeduino Mega 2560 ADK dev board and the 2.8″ TFT Touch Shield. The problem I was experiencing was that when I plugged the 2.8″ TFT Touch Shield (“shield”) into the Seeeduino Mega 2560 ADK (“Seeeduino”), all I got was a white background with the backlight on. There was nothing else going on. I tried just about every library under the sun, every example, my own code, searching Google for solutions, etc. I saw that lots of folks were having this problem, but no one had any solutions. So, I eventually posted the problem to the Seeduino forums.

I didn’t get any replies, only more people with the same issue getting in on the action. Fortunately someone at Seeeduino took pitty on me and emailed me about it. After a couple of emails back and forth it turns out the fix is quite easy. It has to do with the Mega 2560 pinout being different than the standard arduino/seeeduino. As you can see in the image below, the regular Arduino (Uno for instance) has 14 Digital I/O pins and 6 analog input pins whereas the Mega 2560 has 54 digital I/O pins and 16 analog input pins.

Due to this difference the screen has to use different pins. Unfortunately the example sketches in the TFT library don’t tell you that you have to change anything so what you wind up with on the Mega 2560 boards is the TFT screen with a blank white background and the backlight on.

Congratulations! You’ve successfully fixed the TFT library so that you can use it with a Arduino or Seeeduino Mega 2560 or Mega 2560 ADK! On my board I tested it out and everything was great after that! Try the drawCircle sketch from the library examples once you fix this.

The module power comes in on the Vcc pin.  The module includes an onboard 3.3V regulator, so the module should normally be operated off of 3.6 to 5.5V power on this pin to feed the regulator.  Current is typical 55-60mA
