3.5 tft lcd arduino code factory

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).

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.

This is a 3.5” IPS capacitive Touchscreen Display. The module, with a resolution of 480x320, adopts ILI9488 as driver IC and SPI (4-line) communication mode. The board integrates touch chip GT911, employing I2C communication to realize multiple touchpoints controlling. The module also integrates an SD card slot allowing you to easily read the full-color bitmap. There are two modes of wiring supplied, normal pin header wiring and GDI. The latter one requires to work with a main controller board with a GDI interface (e.g. FireBeetle-M0). You can use it with only one FPC line plugging in, which reduces the complexity of the wiring. Furthermore, it features high resolution, wide viewing angle, and simple wiring, which can be used in all sorts of display applications, such as, IoT controlling device, game console, desktop event notifier, touch interface, etc.

With the 3.5 Inch Full-Color Touch TFT Display Shield, you can display vibrant graphics, photos, and text on your projects, bringing them to life like never before. And with the touch functionality, you can create all sorts of interactive projects, from touch-based games and quizzes to touch-controlled home automation systems and beyond.

This blog post will take a closer look at the 3.5 full-color touch TFT display shield and its capabilities. We’ll also explore how to use it with your Arduino. So if you’re ready to add color and interactivity to your Arduino projects, read on!

First, you need to install Arduino IDE Software from its official website Arduino. Here is a simple step-by-step guide on “How to install Arduino IDE“.

my_lcd.Fill_Triangle(x_spec+i*side_len-1,y_spec+(i+1)*h_len-1,x_spec+side_len/2+i*side_len-1,y_spec+i*h_len-1,x_spec+(i+1)*side_len-1,y_spec+(i+1)*h_len-1);

my_lcd.Fill_Triangle(x_spec+i*side_len-1,y_spec+(5-i)*h_len-1,x_spec+side_len/2+i*side_len-1,y_spec+(4-i)*h_len-1,x_spec+(i+1)*side_len-1,y_spec+(5-i)*h_len-1);

my_lcd.Draw_Line(2+random(my_lcd.Get_Display_Width()-4),17+random(my_lcd.Get_Display_Height()-34),2+random(my_lcd.Get_Display_Width()-4),17+random(my_lcd.Get_Display_Height()-34));

my_lcd.Draw_Rectangle(2+random(my_lcd.Get_Display_Width()-4),17+random(my_lcd.Get_Display_Height()-34),2+random(my_lcd.Get_Display_Width()-4),17+random(my_lcd.Get_Display_Height()-34));

my_lcd.Draw_Round_Rectangle(2+random(my_lcd.Get_Display_Width()-4),17+random(my_lcd.Get_Display_Height()-34),2+random(my_lcd.Get_Display_Width()-4),17+random(my_lcd.Get_Display_Height()-34),5);

my_lcd.Draw_Triangle(2+random(my_lcd.Get_Display_Width()-4),17+random(my_lcd.Get_Display_Height()-34),2+random(my_lcd.Get_Display_Width()-4),17+random(my_lcd.Get_Display_Height()-34),2+random(my_lcd.Get_Display_Width()-4),17+random(my_lcd.Get_Display_Height()-34));

my_lcd.Fill_Round_Rectangle(my_lcd.Get_Display_Width()/2-1-120+1, my_lcd.Get_Display_Height()/2-1-60+1, my_lcd.Get_Display_Width()/2-1+120-1, my_lcd.Get_Display_Height()/2-1+60-1,5);

It’s now time to test the circuit! Once you upload the code and the circuit gets the power, it will start the TFT display and shows the messages according to the given code.

The code uses two libraries: LCDWIKI_GUI.h and LCDWIKI_KBV.h. The LCDWIKI_GUI.h library is the core graphics library, and the LCDWIKI_KBV.hlibrary is hardware-specific.

The code defines a function called “show_text(),” which displays text on the TFT display. This function starts by initializing a variable “time_start” with the current time in microseconds. This variable is later used to calculate how long the function took to execute.

Then the code sets the draw color to a blue color using the Set_Draw_color()function, and then it fills a rectangle with this color at the top of the display by calling theFill_Rectangle() function. Next, the code sets the text color to green, the text size to 1, and the text mode to 1, it prints a string “* Universal Color TFT Display Library *” at the center of the display using the Print_String() function.

The code then sets the draw color to a gray color and fills a rectangle at the bottom of the display using the Fill_Rectangle() function. After that, it sets the text color to white, the text size to 1, and the text mode to 1, and then it prints a string “http://abcdefghijklmnopq.1234567890.com” which is a URL at the center of the bottom of the display using the Print_String()function.

After that, the code sets the draw color to red, and it draws a rectangle around the entire display by calling the Draw_Rectangle() function, after that it returns the time taken to execute the function by subtracting the current time in microseconds from the time_start variable.

The code also defines a function called “show_triangle_function()” used to display triangles on the TFT display. Like the previous function, this function also starts by initializing a variable “time_start” with the current time in microseconds, which will be used later to calculate how long the function took to execute.

The code draws crosshairs on display by setting the draw color to blue, and then it draws two lines: a vertical line and a horizontal line, using the Draw_Fast_VLine() and Draw_Fast_HLine() functions, respectively. The vertical line is drawn at the center of the display, and the horizontal line is drawn at the middle of the display.

After that, the code uses a for-loop to draw horizontal lines on both sides of the center horizontal line and another for-loop to draw vertical lines on both sides of the center vertical line.

Next, the code prints the string “sin” at the display’s top left corner, then sets the draw color to a light blue. It uses a for-loop to draw a sin curve on display by plotting pixels at different y-coordinates calculated by applying the sin function to the x-coordinates of the pixels using theDraw_Pixel() function.

Then, the code prints the string “cos” below the “sin” string, and then it sets the draw color to a green color, and it uses another for-loop to draw a cos curve on display by plotting pixels at different y-coordinates calculated by applying the cos function to the x-coordinates of the pixels.

The code prints the string “tan” below the “cos” string, and then it sets the draw color to a yellow color, and it uses another for-loop to draw a tan curve on display by plotting pixels at different y-coordinates calculated by applying the tan function to the x-coordinates of the pixels.

The show_sinewave() function starts by initializing a variable “time_start” with the current time in microseconds, which will be used later to calculate how long the function took to execute. Then it declares an array “buf” of size my_lcd.Get_Display_Width()-2, two variables “x” and “i” and “y” variable, and two variables t, k. It also checks if the width of the display is 320 or not. If it is 320, the t value is 20, and k is 1.1; otherwise, t is 15, and k is 0.7.

Next, the code draws a blue crosshair on display by setting the draw color to blue, and then it draws two lines: a vertical line and a horizontal line, using the Draw_Fast_VLine() and Draw_Fast_HLine() functions, respectively. The vertical line is drawn at the center of the display, and the horizontal line is drawn at the middle of the display.

The show_text()function displays text on the LCD screen. The show_triangle_function() function draws crosshairs and sin, cos, and tan lines on the LCD screen. It starts by drawing blue crosshairs in the middle of the screen using the Draw_Fast_VLine and Draw_Fast_HLine functions. Then it draws sin, cos, and tan lines using the Draw_Pixel function, with the color of each line being different. Finally, it writes “sin,” “cos,” and “tan” in other colors as well.

The show_sinewave() function draws a sinewave on the LCD screen. It starts by drawing blue crosshairs in the middle of the screen. Then it uses a for loop to draw the sinewave, starting at x=1 and incrementing x with each iteration of the loop. It uses the sin() function to determine the y value of each pixel and the Draw_Pixel function to draw the pixel.

The show_grid_lines()function draws grid lines on the LCD screen. It starts by drawing red diagonal lines using the Draw_Line function. Then, it draws blue diagonal lines using the Draw_Line function as well.

The function show_endis called after all the other test functions have run and are used to display the end screen on the LCD. It takes one parameter, run_time, which is the total time taken for the tests to run in microseconds. The function starts by filling the entire screen with a light blue color using the Fill_Screen method. Then it uses the Fill_Round_Rectangle function to draw a filled red rounded rectangle in the center of the screen.

TFT LCD screens combined with Human Machine Interface (HMI) technology result in exciting project ideas applicable to a wide variety of industries. STONE HMI TFT LCD Arduino project ideas. After all, HMI is a smart technology that uses touch to draw out information from both the human user and the display machine.

And when high-quality display screen modules such as STONE Tech’s TFT LCD products are laden with HMI technology, the result is outstanding machine performance capable of bringing out the best in every customer and business.

Now, this article will feature STONE HMI. Furthermore, we will also present some exciting project development initiatives carried out by the company using its vast range of TFT LCD modules paired with HMI technology, and the TFT LCD Arduino project.

HMIs are user-friendly by nature. Graphics and colors can easily be added to the display to communicate with the end-users. Any problems arising from the HMI screen can also be detected easily using color codes, alarms, and sounds. Furthermore, you’ll need only a few touches to fix any issues detected by an HMI device.

What makes HMI a good choice for industrial use is that it is fully flexible and customizable to fit several industrial needs. The TFT LCD screen sizes can be tailor-made to suit the HMI’s application. Furthermore, the software that comes with the machines can be adjusted as well.

STONE Technologies is a proud manufacturer of superior quality TFT LCD modules and LCD screens. The company also provides intelligent HMI solutions that perfectly fit in with its excellent hardware offerings.

STONE TFT LCD modules come with a microcontroller unit that has a cortex-m4 32-bit CPU. Such a module can easily be transformed into an HMI screen. Simple hexadecimal instructions can be used to control the module through the UART port. Furthermore, you can seamlessly develop STONE TFT LCD color user interface modules and add touch control, features to it.

Each customizable TFT-LCD HMI display module comes with free access to STONE’s dedicated design software. STONE TOOLBox software is an easy-to-use program that allows you to set up graphical user interface functions such as:

Also, STONE manufactures several TFT LCD touch screen sizes that range from 3.5 to 15.1 inches. Customized options are also available depending on your needs. There are also plenty of options and models for each screen size.

Indeed, STONE produces a plethora of HMI-ready TFT LCD screens. You won’t have a hard time finding the right display module compatible with your microcontroller projects.

STONE developed an oxygen monitor for an Italian customer. The monitor uses Stone’s 7-inch TFT LCD screen and was connected to an oxygen tank for medical use.

STONE’s display screen was connected to the Arduino development board through UART. But this required a level conversion achieved by the MAX3232. Meanwhile, the same Arduino board was wired to the MAX30100 module through an IIC interface.

Some modifications to the MAX30100 module were made, specifically to the IIC pull-up resistor. The remainder of the project was finished using Arduino codes to finally create a responsive display for heart rate and blood oxygen monitoring.

This project aims to create a fingerprint door lock that can enter, scan, compare, and delete fingerprints. It utilized an STM32 development board, fingerprint identification module, and Stone’s STVC050WT-01 LCD display.

STONE LCD screen’s role here is to display the fingerprint module’s status. As with all other projects, STONE TOOLBox software was used to generate the user interface flashed on the screen. Meanwhile, Stone’s LCD screen was connected to the development board and fingerprint identification module with MCU through UART-TTL signals.

The idea for this project is a real-time display of pictures collected by the camera on the LCD display screen. The TFT LCD STONE module used for this project is a 7-inch serial display module with 800×480 resolution. A camera module, development board, and some wires are needed to complete the project.

The user interface was designed using STONE TOOLBox and Adobe Photoshop. Then, the hardware parts were wired together; some parts needed welding. After that, a simple program was written following MCU to the command control TFT-LCD module.

This particular project used a STONE serial LCD touch display screen. This functions as the main display for the coffee machine. With the screen installed, you can:

RGB lamps that can be controlled through a touch display – this is the aim of this project idea. STONE’s 7-inch TFT LCD display module in STVC070WT-01 was used to connect and control an RGB lamp.

Last but not least is a basic appliance controller made using STONE’s 7-inch TFT LCD touch screen and an STM32 development board. The touch screen controls lights for various parts of the house. The finished product also collects data about humidity, temperature (indoor and outdoor), and air quality.

STONE TOOLBox and graphics software such as Adobe Photoshop was used to design the user interface. Meanwhile, the hardware pieces were wired together and an MCU code was written for the electronic scale to be functional.

STONE’s TFT LCD intelligent touch modules can be paired with Arduino technology to automate a variety of processes. This project clearly demonstrates this.

Here, a sensor directly connected to Arduino Uno is monitored by the display screen in real-time. Moreover, two light bulbs connected to Arduino are directly controlled by the display screen as well.

This project is all about making a car display dashboard using a 10.1-inch STONE LCD touch screen. The on-board display interface for a used car contains the following:

We presented an overview of what HMI technology is, how it works, and which applications use it. Also, we covered Stone’s range of HMI-capable TFT LCD display modules. Furthermore, we discussed a lengthy list of exciting project ideas made using Stone’s superior quality HMI displays.

STONE Technologies is truly your best bet for powering your HMI-driven development ideas(projects based on TFT LCD Arduino, STM32, ESP, etc.). Take inspiration from the actual examples we’ve shown you and build your very own HMI display device today.

This is a 3.5-inch 320 * 480 resolution TFT colour screen. It supports working boards such as Arduino Uno and Arduino mega2560 and Arduino due. Also supports STM32, 51 and other conventional microcontrollers.
