esp32 tft display library free sample

TFT_display_init() Perform display initialization sequence. Sets orientation to landscape; clears the screen. SPI interface must already be setup, tft_disp_type, _width, _height variables must be set.

compile_font_file Function which compiles font c source file to binary font file which can be used in TFT_setFont() function to select external font. Created file has the same name as source file and extension .fnt

New functions have been added to draw smooth (antialiased) arcs, circles, and rounded rectangle outlines. New sketches are provided in the "Smooth Graphics" examples folder. Arcs can be drawn with or without anti-aliasing (which will then render faster). The arc ends can be straight or rounded. The arc drawing algorithm uses an optimised fixed point sqrt() function to improve performance on processors that do not have a hardware Floating Point Unit (e.g. RP2040). Here are two demo images, on the left smooth (anti-aliased) arcs with rounded ends, the image to the right is the same resolution (grabbed from the same 240x240 TFT) with the smoothing diasbled (no anti-aliasing):

An excellent new compatible library is available which can render TrueType fonts on a TFT screen (or into a sprite). This has been developed by takkaO, I have created a branch with some bug fixes here. The library provides access to compact font files, with fully scaleable anti-aliased glyphs. Left, middle and right justified text can also be printed to the screen. I have added TFT_eSPI specific examples to the OpenFontRender library and tested on RP2040 and ESP32 processors, the ESP8266 does not have sufficient RAM due to the glyph render complexity. Here is a demo screen where a single 12kbyte font file binary was used to render fully anti-aliased glyphs of gradually increasing size on a 320x480 TFT screen:

Support has been added in v2.4.70 for the RP2040 with 16 bit parallel displays. This has been tested and the screen update performance is very good (4ms to clear 320 x 480 screen with HC8357C). The use of the RP2040 PIO makes it easy to change the write cycle timing for different displays. DMA with 16 bit transfers is also supported.

Support for the ESP32-S2, ESP32-S3 and ESP32-C3 has been added (DMA only on ESP32 S3 at the moment). Tested with v2.0.3 RC1 of the ESP32 board package. Example setups:

Smooth fonts can now be rendered direct to the TFT with very little flicker for quickly changing values. This is achieved by a line-by-line and block-by-block update of the glyph area without drawing pixels twice. This is a "breaking" change for some sketches because a new true/false parameter is needed to render the background. The default is false if the parameter is missing, Examples:

New anti-aliased graphics functions to draw lines, wedge shaped lines, circles and rounded rectangles. Examples are included. Examples have also been added to display PNG compressed images (note: requires ~40kbytes RAM).

Frank Boesing has created an extension library for TFT_eSPI that allows a large range of ready-built fonts to be used. Frank"s library (adapted to permit rendering in sprites as well as TFT) can be downloaded here. More than 3300 additional Fonts are available here. The TFT_eSPI_ext library contains examples that demonstrate the use of the fonts.

Users of PowerPoint experienced with running macros may be interested in the pptm sketch generator here, this converts graphics and tables drawn in PowerPoint slides into an Arduino sketch that renders the graphics on a 480x320 TFT. This is based on VB macros created by Kris Kasprzak here.

The RP2040 8 bit parallel interface uses the PIO. The PIO now manages the "setWindow" and "block fill" actions, releasing the processor for other tasks when areas of the screen are being filled with a colour. The PIO can optionally be used for SPI interface displays if #define RP2040_PIO_SPI is put in the setup file. Touch screens and pixel read operations are not supported when the PIO interface is used.

An Arduino IDE compatible graphics and fonts library for 32 bit processors. The library is targeted at 32 bit processors, it has been performance optimised for RP2040, STM32, ESP8266 and ESP32 types, other processors may be used but will use the slower generic Arduino interface calls. The library can be loaded using the Arduino IDE"s Library Manager. Direct Memory Access (DMA) can be used with the ESP32, RP2040 and STM32 processors with SPI interface displays to improve rendering performance. DMA with a parallel interface (8 and 16 bit parallel) is only supported with the RP2040.

For other processors only SPI interface displays are supported and the slower Arduino SPI library functions are used by the library. Higher clock speed processors such as used for the Teensy 3.x and 4.x boards will still provide a very good performance with the generic Arduino SPI functions.

"Four wire" SPI and 8 bit parallel interfaces are supported. Due to lack of GPIO pins the 8 bit parallel interface is NOT supported on the ESP8266. 8 bit parallel interface TFTs (e.g. UNO format mcufriend shields) can used with the STM32 Nucleo 64/144 range or the UNO format ESP32 (see below for ESP32).

The library supports some TFT displays designed for the Raspberry Pi (RPi) that are based on a ILI9486 or ST7796 driver chip with a 480 x 320 pixel screen. The ILI9486 RPi display must be of the Waveshare design and use a 16 bit serial interface based on the 74HC04, 74HC4040 and 2 x 74HC4094 logic chips. Note that due to design variations between these displays not all RPi displays will work with this library, so purchasing a RPi display of these types solely for use with this library is NOT recommended.

A "good" RPi display is the MHS-4.0 inch Display-B type ST7796 which provides good performance. This has a dedicated controller and can be clocked at up to 80MHz with the ESP32 (125MHz with overclocked RP2040, 55MHz with STM32 and 40MHz with ESP8266). The MHS-3.5 inch RPi ILI9486 based display is also supported, however the MHS ILI9341 based display of the same type does NOT work with this library.

Some displays permit the internal TFT screen RAM to be read, a few of the examples use this feature. The TFT_Screen_Capture example allows full screens to be captured and sent to a PC, this is handy to create program documentation.

The library supports Waveshare 2 and 3 colour ePaper displays using full frame buffers. This addition is relatively immature and thus only one example has been provided.

The library includes a "Sprite" class, this enables flicker free updates of complex graphics. Direct writes to the TFT with graphics functions are still available, so existing sketches do not need to be changed.

A Sprite is notionally an invisible graphics screen that is kept in the processors RAM. Graphics can be drawn into the Sprite just as they can be drawn directly to the screen. Once the Sprite is completed it can be plotted onto the screen in any position. If there is sufficient RAM then the Sprite can be the same size as the screen and used as a frame buffer. Sprites by default use 16 bit colours, the bit depth can be set to 8 bits (256 colours) , or 1 bit (any 2 colours) to reduce the RAM needed. On an ESP8266 the largest 16 bit colour Sprite that can be created is about 160x128 pixels, this consumes 40Kbytes of RAM. On an ESP32 the workspace RAM is more limited than the datasheet implies so a 16 bit colour Sprite is limited to about 200x200 pixels (~80Kbytes), an 8 bit sprite to 320x240 pixels (~76kbytes). A 1 bit per pixel Sprite requires only 9600 bytes for a full 320 x 240 screen buffer, this is ideal for supporting use with 2 colour bitmap fonts.

If an ESP32 board has SPIRAM (i.e. PSRAM) fitted then Sprites will use the PSRAM memory and large full screen buffer Sprites can be created. Full screen Sprites take longer to render (~45ms for a 320 x 240 16 bit Sprite), so bear that in mind.

The "Animated_dial" example shows how dials can be created using a rotated Sprite for the needle. To run this example the TFT interface must support reading from the screen RAM (not all do). The dial rim and scale is a jpeg image, created using a paint program.

The XPT2046 touch screen controller is supported for SPI based displays only. The SPI bus for the touch controller is shared with the TFT and only an additional chip select line is needed. This support will eventually be deprecated when a suitable touch screen library is available.

The library supports SPI overlap on the ESP8266 so the TFT screen can share MOSI, MISO and SCLK pins with the program FLASH, this frees up GPIO pins for other uses. Only one SPI device can be connected to the FLASH pins and the chips select for the TFT must be on pin D3 (GPIO0).

The library contains proportional fonts, different sizes can be enabled/disabled at compile time to optimise the use of FLASH memory. Anti-aliased (smooth) font files in vlw format stored in SPIFFS are supported. Any 16 bit Unicode character can be included and rendered, this means many language specific characters can be rendered to the screen.

The library is based on the Adafruit GFX and Adafruit driver libraries and the aim is to retain compatibility. Significant additions have been made to the library to boost the speed for the different processors (it is typically 3 to 10 times faster) and to add new features. The new graphics functions include different size proportional fonts and formatting features. There are lots of example sketches to demonstrate the different features and included functions.

Configuration of the library font selections, pins used to interface with the TFT and other features is made by editing the User_Setup.h file in the library folder, or by selecting your own configuration in the "User_Setup_Selet,h" file. Fonts and features can easily be enabled/disabled by commenting out lines.

Anti-aliased (smooth) font files in "vlw" format are generated by the free Processing IDE using a sketch included in the library Tools folder. This sketch with the Processing IDE can be used to generate font files from your computer"s font set or any TrueType (.ttf) font, the font file can include any combination of 16 bit Unicode characters. This means Greek, Japanese and any other UCS-2 glyphs can be used. Character arrays and Strings in UTF-8 format are supported.

It would be possible to compress the vlw font files but the rendering performance to a TFT is still good when storing the font file(s) in SPIFFS, LittleFS or FLASH arrays.

Anti-aliased fonts can also be drawn over a gradient background with a callback to fetch the background colour of each pixel. This pixel colour can be set by the gradient algorithm or by reading back the TFT screen memory (if reading the display is supported).

The common 8 bit "Mcufriend" shields are supported for the STM Nucleo 64/144 boards and ESP32 UNO style board. The STM32 "Blue/Black Pill" boards can also be used with 8 bit parallel displays.

Unfortunately the typical UNO/mcufriend TFT display board maps LCD_RD, LCD_CS and LCD_RST signals to the ESP32 analogue pins 35, 34 and 36 which are input only. To solve this I linked in the 3 spare pins IO15, IO33 and IO32 by adding wires to the bottom of the board as follows:

If the display board is fitted with a resistance based touch screen then this can be used by performing the modifications described here and the fork of the Adafruit library:

If you load a new copy of TFT_eSPI then it will overwrite your setups if they are kept within the TFT_eSPI folder. One way around this is to create a new folder in your Arduino library folder called "TFT_eSPI_Setups". You then place your custom setup.h files in there. After an upgrade simply edit the User_Setup_Select.h file to point to your custom setup file e.g.:

You must make sure only one setup file is called. In the custom setup file I add the file path as a commented out first line that can be cut and pasted back into the upgraded User_Setup_Select.h file. The ../ at the start of the path means go up one directory level. Clearly you could use different file paths or directory names as long as it does not clash with another library or folder name.

I"ve bought on AliExpress a cheap 1.77 color display module. Getting it to work on an Arduino was straight forward. But the Arduino is slow. I also got it working on an Esp8266, which was also straight forward. However getting it to work on an ESP32 was a little harder. I"ve tried several libraries, e.g. AdaFruit and UcgLib. These didn"t work. After some investigations the SPI speed was too high for the display. I tried to change the libs to reduce the speed. I didn"t work either.

So I left the project a few weeks and I started again. I searched for all possible libraries for ST7735 and ESP32. I found some and there was one I manged to get to work.

After tweaking the user_setup.h file I managed to get it to work.The settings that ware important to change was to change the ST7735 defines. Default I choose the first. This one didn"t work. I reduce SPI speed, which had no effect either. Than after some changes and tweaking connections and setting I finally worked. The ST7735 defines all work except the first one with my TFT-screen. I reset all to default and the SPI-speed and it kept working. It works at a 27 MHz speed, which leave me with 450 ms for the 11 test pages. If I increase the speed to the next value of 40 MHz I see errors in the display. So 27 MHz is max for me.

I also checked all other ST7735 defines, and for my TFT the ST7735_GREENTAB3 showed the correct colors. The other values show the wrong colors, but gave an image.

//#define ILI9488_DRIVER // WARNING: Do not connect ILI9488 display SDO to MISO if other devices share the SPI bus (TFT SDO does NOT tristate when CS is high)

The content is intended to be updated from time to time, I will add more details if I found new display or library update. You can also help me enrich the content by leaving comments below.

You can run various IoT projects prefectly without any display. But not all IoT project only feed data in single direction (IoT to server), some IoT also gather real time information from the server for displaying.

My previous instructables, ESP32 Photo Clock is am example, it download a current minute photo from the Internet, decode the JPEG photo and display it.

Many Arduino projects use monochrome display, one of the reason is the limited resources of a MCU. 320 pixels width, 240 pixels height and 8 bits color for each RGB color channel means 230 KB for each full screen picture. But normal Arduino (ATmega328) only have 32 KB flash and it is time consuming (over a second) to read data from SD card and draw it to the color display.

ESP32 have changed the game! It have much faster processing power (16 MHz vs 240 MHz dual core), much more RAM (2 KB vs over 200 KB) and much more flash (32 KB vs 4 MB), so it is capable to utilize more color and higher resolution image for displaying. At the same time it is capable to do some RAM hungry process such as Animated GIF, JPEG or PNG file decoding, it is a very important feature for displaying information gathered from the internet.

Color display have many type of interfaces: Serial Peripheral Interface (SPI), 6-bit, 8-bit, 16-bit, 18-bit and 24-bit parallel interfaces and also NeoPixel!

SPI dominate the hobby electronics market, most likely because of fewer wire required to connect. Most display in my drawer only have SPI pins breaking out, so this instructables focus on SPI display and a few 8-bit display.

NeoPixel matrix is a very special type of color display. If you are interested in NeoPixel matrix display, here are some of my instructables using it:

There are various color display for hobby electronics: LCD, IPS LCD, OLED with different resolutions and different driver chips. LCD can have higher image density but OLED have better viewable angle, IPS LCD can have both. OLED have more power efficient for each light up pixel but may have burn-in problems. Color OLED operate in 14 V, it means you need a dedicate step-up circuit, but it is not a problem if you simply use with a break-out board. LCD in most case can direct operate in 3.3 V, the same operating voltage as ESP32, so you can consider not use break out board to make a slimmer product.

Software support on the other side also influence your selection. You can develop ESP32 program with Arduino IDE or direct use ESP-IDF. But since ESP-IDF did not have too much display library and not much display hardware supported, so I will concentrate on Arduino display libraries only.

For the beginner, I think buying adafruit, or similar supportive vendor, hardware and using its Arduino library can have good seamless experience (though I have no budget to try it all). TFT_eSPI library have better performance but configuration require make changes in the library folder. Ucglib and UTFT-ESP run a little bit slow but it support many hardware and it is a popular library, you can find many Arduino projects using it. LovyanGFX library start appear at 2019, it support many dev device such as M5Stack, M5StickC, TTGO T-Watch, ODROID-GO, ESP-WROVER-KIT, WioTerminal and more. I am also writing a new library called Arduino_GFX since 2019.

OLED have a big advantage, the pixel only draw power if it lights up. On the other hand, LCD back light always draw full power even you are displaying a black screen. So OLED can help save some power for the project powered by a battery.

The initial code have some variation, the color order can be RGB or BGR and the y coordinate range also have a few pixels variation. Some library differential it by red, green or black tag but the tag color may not always help. The worst case is alter the tag option one by one until you can see a fine result. The above last picture is an example of using wrong tag option, you can find 3 pixels height noise bar on the top.

Thanks for the popularity of wearable gadget, I can find more small size IPS LCD in the market this year(2018). The above picture is an 0.96" 80x160 IPS color LCD using ST7735 driver chip. As you can see in the 3rd picture, you can treat it as a 128x160 color display in code but only the middle part is actually displaying. The 4th picture is the display without breakout board, it is thin, tiny and very fit for a wearable project!

SSD1283A is 1.6" 130x130 display, it claim only consume 0.1 in sleep mode and backlight turned off. In sleep mode the last drawn screen still readable under sufficient lighting.

ST7789 also a common driver chip in ESP32 community. One of the reason is ESP32 official development kit using it. As same as ILI9341, ST7789 also can drive 240x320 resolution.

This also the highest pixel density color display in my drawer. As same as normal LCD, it can direct operate in 3.3 V, so it is very good for making slim wearable device.

There are many display libraries that can support various hardware. I have picked 4 of most popular Arduino library for comparison:Adafruit GFX Family

The display speed is one of the most important thing we consider to select which library. I have chosen TFT_eSPI PDQ test for this comparison. I have made some effort to rewrite the PDQ test that can run in 4 libraries. All test will run with the same 2.8" ILI9341 LCD.

As I found TFT_eSPI is the most potential display library for ESP32 in this instructables, I have paid some effort to add support for all my display in hand. The newly added display support marked letter M in red at the above picture, here is my enhanced version:

Adafruit sell various display module in hobby electronics market and they also have very good support in software level. Their display libraries all built on a parent class called Adafruit_GFX, so I call it Adafruit GFX Family. This library generally support most Arduino hardware (also ESP32).

In Arduino Library Manager simply search "adafruit display", you can see all the family members. If you want to install it, say ILI9341, simply select "Adafruit ILI9341" and then click install. Remember also install its dependent library "Adafruit GFX Library".

This library method signature is very similar to Adafruit GFX, but it is tailor-made for ESP8266 or ESP32. I think the source code is optimised for ESP32, so the PDQ result is much faster than other libraries.

Note: The most difficult part using this library is you are required to configure this library before you can use it. The configuration file is located at the library folder, it should be "Arduino/libraries/TFT_eSPI/User_setup.h" under you own documents folder. It have many comments help you to do that, please follow the comments step by step to finish the configuration. Here is my User_setup.h for ILI9341:

ESP32 + ILI9341 can run at SPI speed 40 MHz, it require some code change at library folder. The above pictures are the fine tuned result. Here are the code change summary:

ST7735 and ILI9341 are the most popular display, this 2 are better option for the beginner. You may notice LCD have a big weakness, the viewable angle, some color lost outside the viewable angle and the screen become unreadable. If you have enough budget, OLED or IPS LCD have much better viewable angle.

In most case, we study how to use a code library by searching sample on the web. I have tried search four libraries keyword in Github, Adafruit is most popular and UTFT the second.

Only Adafruit GFX Family is fully configurable in user code level, other 3 libraries require some configuration in the library folder. And also Adafruit have very good portal, there are many detailed post teach you how to use their products.

ILI9341 should be most valuable display for the beginner. Adafruit GFX Library should be most easy to use for the beginner, and since TFT_eSPI have very similar method signature, it is very easy to switch to a faster library later on.

OLED require 14 V to light up the pixel so it is not easy to decouple the breakout board. On the other hand, LCD (also IPS LCD) usually operate in 3.3 V, as same as the ESP32. In most case, there are only the LED control circuit required between LCD and ESP32, i.e. a transistor and few resistors. So it relatively easy to make it.

If you read through the data sheet of the color display, you may find most of color display can support 18 bit color depth (6 bit for each RGB channel). 18 bit color depth can have a better image quality that 16 bit color depth (5 bit in red and blue channel, 6 bit for green channel). However, only Ucglib actually run at 18 bit color depth (262,144 colors), other 3 libraries all run at 16 bit color depth (65,536 colors). It is because 18 bit color depth actually require transfer 3 bytes (24 bit) of data for each pixel, it means 50% more data require to transfer and store in memory. It is one of the reason why Ucglib run slower, but it can have a better image quality.

Thank you very much for posting this detailed review of the color display option available for "Duino users. You have saved me hours, maybe days of time wandering the web looking for information.0

Great article! Very interested in round displays. There are available round displays based on st7687s (128 * 128) and st7789 (240 * 240), but I have not found any information on practical use.

Hello! Yes, I purchased this display from keyestudio, connected it to esp32 using this library from dfrobot. It is only necessary to consider that the pinout of the display connectors differs from dfrobot and keyestudio.

I"m wanting to connect a VGA camera, the sort you find as a little module on eBay with OVPxxxx chip, to a screen such as ILxxxx family, which appears to have direct VGA input. I think it will work if I connect the camera directly with no MCU, but I"d also like to add a cross-hair to the display (for a drill targetting system). I wonder is it possible to intercept the serial video data and change individual pixels in a streaming fashion, instead of loading a whole screen into memory, changing it and passing it on? I ask because it seems to me it would need a much less powerful MCU.0

Thank you so much for such a great article. I have been trying to choose the best library to use for a project that will use either a SSD1351 or a ST7735 both being 128x128. The key to my project is to be able to dump a frame buffer in to the display and then recalculate the next frame buffer. :)

Those 2 pins must be dedicated to the display, otherwise the display will get confused without the CS pin. One DAT/CLK to LCD and another DAT/CLK to I2C.

Hello! Thank"s for your instruction. I want to use your 8pin ili9486 320x480 spi display with one of your presented libraries and esp32. 1.) Could you please tell me the connections between the display and the esp32 and 2.) which numbers do I have to write into the line utft myglcd (ili9486,?,?,?,?)?

This tutorial shows how to use the I2C LCD (Liquid Crystal Display) with the ESP32 using Arduino IDE. We’ll show you how to wire the display, install the library and try sample code to write text on the LCD: static text, and scroll long messages. You can also use this guide with the ESP8266.

Before displaying text on the LCD, you need to find the LCD I2C address. With the LCD properly wired to the ESP32, upload the following I2C Scanner sketch.

After uploading the code, open the Serial Monitor at a baud rate of 115200. Press the ESP32 EN button. The I2C address should be displayed in the Serial Monitor.

Displaying static text on the LCD is very simple. All you have to do is select where you want the characters to be displayed on the screen, and then send the message to the display.

In this simple sketch we show you the most useful and important functions from the LiquidCrystal_I2C library. So, let’s take a quick look at how the code works.

The next two lines set the number of columns and rows of your LCD display. If you’re using a display with another size, you should modify those variables.

Then, you need to set the display address, the number of columns and number of rows. You should use the display address you’ve found in the previous step.

To display a message on the screen, first you need to set the cursor to where you want your message to be written. The following line sets the cursor to the first column, first row.

Scrolling text on the LCD is specially useful when you want to display messages longer than 16 characters. The library comes with built-in functions that allows you to scroll text. However, many people experience problems with those functions because:

The messageToScroll variable is displayed in the second row (1 corresponds to the second row), with a delay time of 250 ms (the GIF image is speed up 1.5x).

In a 16×2 LCD there are 32 blocks where you can display characters. Each block is made out of 5×8 tiny pixels. You can display custom characters by defining the state of each tiny pixel. For that, you can create a byte variable to hold  the state of each pixel.

In summary, in this tutorial we’ve shown you how to use an I2C LCD display with the ESP32/ESP8266 with Arduino IDE: how to display static text, scrolling text and custom characters. This tutorial also works with the Arduino board, you just need to change the pin assignment to use the Arduino I2C pins.

We hope you’ve found this tutorial useful. If you like ESP32 and you want to learn more, we recommend enrolling in Learn ESP32 with Arduino IDE course.

This module is the 3.2” version of the ESP32 touchscreen display, based on ESP32-WROVER, with a built-in 2M pixel OV2640 camera. The LCD is 320x240 TFT, with driver is ILI9341, it uses SPI for communication with ESP32, the SPI main clock could be up to 60M~80M, make the display smooth enough for videos; and the camera OV2640 with pixel 2M, with this camera, you can make applications such as remote photography, face recognition…

While the camera not used, you can freely use all these pins with the breakout connectors, to connect the ESP32 display with sensors/ actuators, suitable for IoT applications.

were missing for my display (hailege, 2,8 tft, spi, il9431, https://www.amazon.de/-/en/gp/product/B07YTWRZGR/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1). so it might just be that the led backlight isnt being turned on. but of course the tip might not help with the st7796s.

I wanted to try these ST7735 inexpensive displays that can be found all over the internet, so I ordered a couple for a few euros each. My quick research showed that a number of libraries support them and it turns out that you can display anything you want. Of course, we are not talking about playing modern games on it or watching 4k videos. These are just simple displays that can be really helpful to any project.

I used an older version of ESP32, the DEVKITV1, and actually the smaller version with the 30 pins. If you have a different one please try to find the correct pinout because they differ. Here is the pinout diagram from mine

And here is how the TFT looks. As you see it also has a port for an SD card if you want to use e.g. for reading images from it. In my case, I didn’t connect it.

Once you have the connections ready next step is to install the TFT library in your Arduino IDE. Go to Tools – > Manage Libraries and then search for TFT_eSPI and click install. Alternatively, crab the lib from here.

Next step is to configure the pins in the file User_Setup.h of the library. In your favourite text editor open the file and change the pins in lines 124,125,126. Here how mine looks:

After this, you can pick any of the examples from the library to upload to your ESP32 microcontroller. Some of them are really nice. For testing, I connected a DHT11 temperature/humidity sensor and I displayed the readings in the ST7735. Sweet!

The code is not 100% as I need to find a better way to update the screen instead of filling the whole screen with black background before an update. There is documentation about it here https://learn.adafruit.com/adafruit-gfx-graphics-library/graphics-primitives I need to go through it.

To get the screen on the LilyGO TTGO T-display ESP32 running need the TFT_eSPI library. This is a "graphics and fonts library for ESP8266 and ESP32 processors with drivers for ILI9341, ILI9163, ST7735, S6D02A1, ILI9481, ILI9486, ILI9488, HX8357D and ST7789 based TFT displays that support SPI".

Whilst you can install the library with the Library manager of Arduino I would advise you to install the version from Github. In that way you can be sure you get the newest version. You will be able to update the library within the Library manager or overwrite the old files manually. Be sure to check whether the manual changes you have to made are still there after an update (see below at "Configure the TFT_eSPI library to use the ST7789V in the correct way")!

Manually installGo to https://github.com/Bodmer/TFT_eSPI/releases and download the Source code (ZIP) of the newest release or if you want even a newer unreleased version you can download the library by clicking on Clone or download on the upper right corner on https://github.com/Bodmer/TFT_eSPI.

Save the file TTGO_T_Display.h to the folder User_setups of the TFT_eSPI library you just installed. Most likely this will be C:\Users\[username]\Documents\Arduino\libraries\TFT_eSPI-master\User_Setups

This library is only needed for the demo sketch of LilyGO. If you prefer another library for handling the button presses you are free to use so. I personally like the Button 2 library. It does fit my needs quite well.
