arduino tft lcd menu library brands

TcMenu supports a wide range of rendering devices, from HD44780 based units using our LiquidCrystal fork through to mono OLEDs and full colour TFT displays using Adafruit_GFX and TFT_eSPI library. Over to the left you see an example of rendering to OLED device with title widgets.

How a menu will look on the device will largely depend on which display is used. However, there are a few common features of all displays. They can generally all have a title, and the title can nearly always contain title widgets. Title widgets provide a way to present the graphical state of something within the system in a small icon, the most common would be the signal strength indicator, or a connection status icon. An example showing this is presented below:

From the above diagram we can see that most graphical and LCD displays (except Uno cases) extend from at least the BaseGraphicalRenderer. And in fact all the true graphical displays extend from GraphicsDeviceRenderer and then have a custom drawable. The benefit of GraphicsDeviceRenderer is that does all the complex logic, and the drawable just has to implement the drawing glue code that calls into the library.

Type: BaseMenuRenderer in BaseRenderers.h - this just provides a few functions to help formatting items, taking over the display and handling dialogs.

In all cases the display plugins will create a global variable called renderer in your sketch. It will be at least of type MenuRenderer meaning that you can rely on an absolute base set of functionality. In most cases it will be of BaseGraphicalRenderer or GraphicsDeviceRenderer so you will be able to rely on nearly all functions being available.

Usually, the renderer is initialised during menu setup and this starts a task manager timer task that calls the display back frequently to check if anything needs drawing. It is this task that keeps the screen up-to-date.

Controllers allow you far more control over a dialog, you can not only add additional menu items and buttons to the dialog, but you can also be informed when dialog buttons are pressed before the dialog ends, and be informed when it is initialising.

You can add additional menu items of any type to the dialog, you can even add more buttons, additional buttons should be of this type [https://www.thecoderscorner.com/ref-docs/tcmenu/html/class_local_dialog_button_menu_item.html].

The easiest way to use touch support, is from tcMenuDesigner where it can be automatically added to appropriate display devices, this just explains how designer adds touch support for those who want more information, or wish to do it manually.

Some displays are buffered by default, these include nearly all monochrome displays and the LTDC frame buffer support. However, TFT displays are typically not buffered into local memory as the memory requirements would be too high. However, if instead of buffering all 16-bit (or 32-bit) color information, we only buffer a palette then only 2 or 4 bits are needed per pixel. This reduces the memory requirement by about 4-8 times.

Further, we only tend to draw one thing at once, so if we also reduce the height of the buffer, for example, to handle the largest menu item height memory is reduced further. In the case of a 320x40 4 color palette buffer for Adafruit_GFX memory requirement is about 3200 bytes. For TFT_eSPI, the requirement would be about 6400 bytes as the buffers are 4 bit (16 color).

CAUTION: It will return nullptr if the dimensions are beyond the size that is supported. These dimensions are normally set in the code generator plugin as the line buffer size. If you’re using tcMenu code generator, then the lines to buffer are set up

In the oscilloscope, signal data is read from Arduino’s pin A5. This data value is mapped to display coordinates. Then the value is used to draw each pixel to create the waveform of the signal

In this article, you will learn how to use TFT LCDs by Arduino boards. From basic commands to professional designs and technics are all explained here.

In electronic’s projects, creating an interface between user and system is very important. This interface could be created by displaying useful data, a menu, and ease of access. A beautiful design is also very important.

There are several components to achieve this. LEDs,  7-segments, Character and Graphic displays, and full-color TFT LCDs. The right component for your projects depends on the amount of data to be displayed, type of user interaction, and processor capacity.

TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven LCDs with a few segments.

In Arduino-based projects, the processor frequency is low. So it is not possible to display complex, high definition images and high-speed motions. Therefore, full-color TFT LCDs can only be used to display simple data and commands.

In this article, we have used libraries and advanced technics to display data, charts, menu, etc. with a professional design. This can move your project presentation to a higher level.

After choosing the right display, It’s time to choose the right controller. If you want to display characters, tests, numbers and static images and the speed of display is not important, the Atmega328 Arduino boards (such as Arduino UNO) are a proper choice. If the size of your code is big, The UNO board may not be enough. You can use Arduino Mega2560 instead. And if you want to show high resolution images and motions with high speed, you should use the ARM core Arduino boards such as Arduino DUE.

In electronics/computer hardware a display driver is usually a semiconductor integrated circuit (but may alternatively comprise a state machine made of discrete logic and other components) which provides an interface function between a microprocessor, microcontroller, ASIC or general-purpose peripheral interface and a particular type of display device, e.g. LCD, LED, OLED, ePaper, CRT, Vacuum fluorescent or Nixie.

The LCDs manufacturers use different drivers in their products. Some of them are more popular and some of them are very unknown. To run your display easily, you should use Arduino LCDs libraries and add them to your code. Otherwise running the display may be very difficult. There are many free libraries you can find on the internet but the important point about the libraries is their compatibility with the LCD’s driver. The driver of your LCD must be known by your library. In this article, we use the Adafruit GFX library and MCUFRIEND KBV library and example codes. You can download them from the following links.

You must add the library and then upload the code. If it is the first time you run an Arduino board, don’t worry. Just follow these steps:Go to www.arduino.cc/en/Main/Software and download the software of your OS. Install the IDE software as instructed.

First you should convert your image to hex code. Download the software from the following link. if you don’t want to change the settings of the software, you must invert the color of the image and make the image horizontally mirrored and rotate it 90 degrees counterclockwise. Now add it to the software and convert it. Open the exported file and copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are sizes of image. you can change the color of the image in the last input.

Upload your image and download the converted file that the UTFT libraries can process. Now copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are size of the image.

In this template, We converted a .jpg image to .c file and added to the code, wrote a string and used the fade code to display. Then we used scroll code to move the screen left. Download the .h file and add it to the folder of the Arduino sketch.

In this template, We used sin(); and cos(); functions to draw Arcs with our desired thickness and displayed number by text printing function. Then we converted an image to hex code and added them to the code and displayed the image by bitmap function. Then we used draw lines function to change the style of the image. Download the .h file and add it to the folder of the Arduino sketch.

In this template, We added a converted image to code and then used two black and white arcs to create the pointer of volumes.  Download the .h file and add it to the folder of the Arduino sketch.

In this template, We added a converted image and use the arc and print function to create this gauge.  Download the .h file and add it to folder of the Arduino sketch.

while (a < b) { Serial.println(a); j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 255, 255)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

while (b < a) { j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 0, 0)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

In this template, We display simple images one after each other very fast by bitmap function. So you can make your animation by this trick.  Download the .h file and add it to folder of the Arduino sketch.

In this template, We just display some images by RGBbitmap and bitmap functions. Just make a code for touchscreen and use this template.  Download the .h file and add it to folder of the Arduino sketch.

Like the second poster to this question is seems has a reading comprehension program. I don"t need to make that work or find the errors in it. I need a menu already built for this device. I thought that was quite clear.

Probably you know that programming nice menus take some coding time. When it comes to TFT LCD with a touch screen, it becomes even more time-consuming. To save precious time, Jeremy from thecustomgeek offers his ready to use open source menu...

Probably you know that programming nice menus take some coding time. When it comes to TFT LCD with a touch screen, it becomes even more time-consuming. To save precious time, Jeremy from thecustomgeek offers his ready to use open source menu interface designed for Arduino with TFT LCD. LCD with touch screen is one from Adafruit, which can be various layouts including Arduino shield or for a breakout board.

LCD is driven by using Lady Adas TFTLCD with touchscreen libraries. And now some of the menu features. It supports button screens that can be activated by touching them. Currently, there are 5 screens with 6 buttons in each of them. Menu titles and icons can be customized by changing several settings. There is a home icon for fast shortcuts to the main screen. There is also PWM controlled back-light and other modes that are stored in EEPROMto restore the last settings after power off.

There are a few common TFT display drivers on the electronics hobbyist market, and a handful of libraries that work with them. TFT displays are high resolution and full color, unlike the OLED or ePaper displays mentioned in this repository. Most libraries for color TFT displays implement the usual 24-bit RGB color space, where 0xFF0000 is red, 0x00FF00 is green, and 0x0000FF is blue.

TFT displays can be slow to update. Therefore, it’s sometimes usefil to draw only part of the display at once. Adafruits GFX library includes a Canvas class, which lets you update elements offscreen and then draw them. It doesn’t speed up the display, but it can simplify drawing a subset of the screen. See this example to see it in use. Other libraries don’t include a canvas, but you can draw a filled rectangle over part of the screen and then draw on top of it, as shown in this example for the ILI9225.

Most TFT displays tend to have an SPI interface, with some extra pins, as explained on the main page of this repo. Some displays, like MakerFocus’ 1.3” TFT, do not implement the CS pin. For this board and others like it, initializing them with SPI_MODE3 works.

All of the displays listed below have been tested with the Adafruit_ST7735/ST7789 libraries and the Adafruit_GFX library, with the modifications mentioned below.

MakerFocus 1.3” LCD Display, no MicroSD, Amazon link - This display does not have a CS pin, so it can’t be used with other SPI devices at the same time. It works with the Adafruit_ST7789 library, but you have to change the init() function to include the SPI mode like so:

There’s no standard library for TFT screens, unfortunately. Vendors tend to support the displays they make in their own breakout boards, and not others. As with other types of displays, a well-supported library like the Adafruit libraries makes the display worth more, but limits you to the types of displays that vendor offers. Display manufacturers like Ilitek and Sitronix do not appear to release their own libraries for their displays.

The Adafruit_ST7735/7789 library and Adafruit_GFX library works well with some of the Sitronix boards above. It does not support the DFRobot ST7867S board, however.

The DFRobot_ST7687S library has slow refresh rate on the ST7687S board. It’s unclear whether the issue is the library or the board, however. I have yet to find another library to use with this display, though there are a couple other vendors for the board itself on Amazon. Unfortunately the u8g2 library doesn’t support this display, though it does support many of the Sitronix boards.

The TFT_22_ILI9225 library works with this display, and its methods are well documented. Its graphics API is different than some of the other graphics libraries, and doesn’t implement the Printable API, so you can’t use commands like print() and println() with it. It has its own drawText() method instead, which takes an Arduino String object. It comes with a few built-in fonts, and includes many of the Adafruit GFX fonts, and you can generate your own fonts using the The squix.ch custom font generator. Set the settings to

Arduino TFT LCD Screen is a backlit LCD screen with headers. You can draw text, images, and shapes to the screen with the TFT library. There is an onboard micro-SD card slot on the back of the screen that can, among other things, store bitmap images for the screen to display. The micro-SD slot is accessible through the SD card library.

Arduino TFT LCD Screen headers are designed to fit into the socket on the front of the Arduino Esplora, but it is compatible with any AVR-based Arduino (Arduino Uno, Arduino Leonardo) or with the Arduino Due. It is also compatible with Arduino Robot.

Arduino TFT LCD Screen is 1.77" diagonal, with 160 x 128 pixel resolution. The TFT library interfaces with the screen"s controller through SPI when using the TFT library. The screen runs on +5 VDC and the LED backlight is dimmable by PWM

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 libraries from Adafruit to help us easily communicate with the LCD. The libraries include the Adafruit GFX library which can be downloaded here and the Adafruit ST7735 Library which can be downloaded here.

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.

The first thing, as usual, is to include the libraries to be used after which we declare the pins on the Arduino to which our LCD pins are connected to. We also make a slight change to the code setting reset pin as pin 8 and DC pin as pin 9 to match our schematics.

Next, we create an object of the library with the pins to which the LCD is connected on the Arduino as parameters. There are two options for this, feel free to choose the most preferred.

The complete code for this is available under the libraries example on the Arduino IDE. Don’t forget to change the DC and the RESET pin configuration in the code to match the schematics.

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.

The demos are developed based on the HAL library. Download the program, find the STM32 program file directory, and open the STM32 with four project folders: DisplayString, DrawGraphic, ShowImage, and Touchscreen.

I"ve just followed a tutorial so that when a button is pressed it goes through a menu. Click once, next slide. Only issue is it isn"t appearing on my screen at all. It has uploaded but I"m a total novice when it comes to breadboards etc. Here is my code:
