tft lcd shield arduino mega made in china

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (5" diagonal) bright (12 white-LED backlight) and colorful 480x272 pixels with individual pixel control. As a bonus, this display has a capacitive touch panel attached on screen by default.

The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino Mega 2560.

This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. You can connect more sensors, buttons and LEDs.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!

If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.

I designed the specific PCB for interfacing MEGA and TOUCHSCREEN. I ordered JLCPCB to produce it100k+ in-stock electronic components for online parts sourcing & PCB assembly, 24-hour rapid SMT assembly

I just installed the Arduino 1.8.10 version and kept my librairies Adafruit_GFX, MCUFRIEND_kbv, Touchscreen, LiquidCrystal_I2C, MFRC522, RF24 and ds3231

I used a logic analyser to review the Texas Instrument chip used for the screen, this showed the best option seemed to be to attach the IRQ to a pin on arduino as an ege triggered interrupt. rather than use the polll techniues and read while low.

I puzzled some hours with exactly the same hardware setup and made a quick & dirty, but successfully test script, combining LCD, Touch and SD Card Features.

I have some notes that you should consider, thank you for uploading the photo of the circuit that you have installed in your TFT. Please disconnect it as soon as possible, there are some details that you should know before your TFT suffers irreparable damage!

The resistive voltage divider 5V-3V3, is nothing more than a circuit adapted to achieve that the signal with 5V logic that comes out of the arduino MEGA, is reduced to 3.3V and can be interpreted by the TFT controller without burning it with a voltage that is not correct.

The 5V input signal is the one that comes from each pin of the arduino MEGA, the 3.3V output signal is the one we get from the junction point between R1 and R2. To obtain 3.3V R2 must be twice the value of R1. If R1 = 10K, then R2 is equal to 20K.

These are the 5 circuits that I built in each control line between the MEGA and the TFT, in each one these are the values: R1 = 10K and R2 = 20K (10K + 10K)

This TFT LCD Screen Module , not just a LCD break but include the Touch , SD card and Flash design. So it"s a powerful extension module for your project.

Kuongshun Electronic, one of the international well-known manufacturers and suppliers of 3.5 inch tft touch screen module for mega 2560 r3 which is situated in China, now has quality products for sale. We are equipped with a group of professional and experienced workers, as well as advanced equipment. You can rest assured to buy discount and low price 3.5 inch tft touch screen module for mega 2560 r3 made in China from us and check the pricelist with us.

I changed the Adafruit libraries for TFT: GFX , TFTLCD and TouchScreen. I join all in this one library, the library SPFD5408, to avoid problems with duplicate libraries and enables also have the original library Adafruit ready for use in other projects with another TFT hardware.

This module is a 3.5-inch TFT LCD module with “320X480” resolution and 65K color display. It is suitable for Arduino Uno and Mega2560 development boards, and also supports SD card expansion function. It uses 8-bit parallel port communication, and the driver IC is ILI9486.

The 3.5-inch display is a ready-made shield for Arduino Uno, which can also be placed on the Arduino Mega. The pins of this shield are designed to be easily installed on the Arduino. The bad point about these modules is that they use all Arduino Uno pins.

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work  you can check my particular tutorial. Here you can download that file:
