3.5 tft lcd shield arduino quotation
Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (3.5" diagonal) bright (6 white-LED backlight) and colorful (18-bit 262,000 different shades)! 320x480 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel with controller XPT2046 attached by default and a optional capacitive touch panel with controller FT6236 attached by default, so you can detect finger presses anywhere on the screen and doesn"t require pressing down on the screen with a stylus and has nice glossy glass cover.
The pin32 (SDO) of 3.5 display module is also used by touch panel or SD card SPI interface, so we must cut off this pin to avoid conflict with the touch panel or SD card.
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 (Due/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.
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:

Hello everyone to my new tutorial in which we are going to program arduino for tft lcd shield of 3.5" with ILI9486 driver, 8 bit. I found it important to write this tutorial as if we see we find tutorial for 1.44, 1.8, 2.0, 2.4, 2.8 inch shields however there are no or less tutorials available for 3.5" shield as its completely different from other smaller tft lcd shields -adafruit tft lcd library doesn"t even support ILI9486 driver in 3.5" tft lcd, it supports drivers of tft shields lesser then 3.5"
Go through the above link to know better, lets start with our tutorial however if we can"t use Adafruit_TFTLCD library which library will we use ?, there"s a simple answer to this that"s MCUFRIEND_kbv library which helps to use 3.5" tft lcd shield, if you see this library makes it much more easier to program arduino for tft lcd shield than adafruit as we have to simply create a tft object in MCUFRIEND_kbv library and then using that we can control the tft lcd shield however in Adafruit_TFTLCD library we will have to create the object and also define connections which makes it a very long task.
Once added, create the tft object using library name and a name for object, you can also define some color codes for text which we are going to type, using the define function and giving color code. This all is to be done before setup.#include
Its time to now start our tft lcd screen and change the background, this is to be done by using some simple functions by obtaining the tft ID and changing the background bytft.fillScreen("color_name");void}
Now we will be programming in loop for printing text on TFT LCD shield, for that we will be using a number of functions such as -tft.setCursor("x","y");x means the position from the x axis on screen and y means position from the y axis on screen of tft lcd shield.tft.setTextSize("number");number here refers to text size which take parameter as number you can give any number from 1 according to your requirements.tft.setTextColor("color");color here means to give the color name we had defined before setup, this makes the text color as whatever you give.tft.print("value");value is nothing but what you want to print, whatever you give as value must be in double quotes.void loop() {// put your main code here, to run repeatedly:tft.setCursor(0,0);tft.setTextSize(3);tft.setTextColor(WHITE);tft.print("my first project with tft -");tft.setCursor(0,70);tft.setTextSize(2);tft.setTextColor(RED);tft.print("welcome to the world of arduino and display , myself I love arduino and game programming very much. This is why I have my own youtube channel in which I share my arduino projects and games made by me , isn"t it amazing !");}
Graphics which we see in our phone is combination of square, rectangle, circle, triangle, lines. This is why here we will learning how to draw the following shapes.tft.drawRect(x,y,width,height,color);x means the position from the x axis of the screen, y means the position from y axis of the screen, width refers to set the width of rectangle, height refers to set the height of the rectangle and color means the color of rectangle you want it to be. You can use this same function by simply keeping the height and width same.tft.drawCircle(x,y,radius,color);x means the position from the x axis of the screen, y means the position from y axis of the screen, radius is a para to set the radius of circle and color means the color of circle you want it to be.tft.drawTriangle(x1,y1,x2,y2,x3,y3,color);x1, y1, x2 etc. are to set the position of triangle"s three points from which lines are drawn.tft.drawLine(x1,y1,x2,y2,color);x1 and y1 are to set point 1 from which line is made to point 2 which is set by x2 and y2.
