tft lcd esp32 price

The Makerfabs 3.5 inch TFT Touch is great but the refresh rate is always a problem, some customers feedback they want a higher speed display. But as the ESP32 has limited pins, we do not have a good way for that, until we find the ESP32-S2, which do not have BLE(compares to ESP32), but more pins, right for such a parallel TFT.

This 3.5" 320x480 TFT LCD driver is ILI9488, it uses 16bits parallel line for communication with ESP32-S2, the main clock could be up to 20MHz, making the display smooth enough for video displays. With this display, you can freely to create more IoT display projects, check the demo project in the video:

Besides, there 2 onboard Mabee pins(A I2c and an IOs) with the breakout connectors, to connect the ESP32-S2 display with sensors/ actuators, suitable for IoT applications.

Makerfabs has launched a 3.5-inch TFT touchscreen display with built-in WiFi and Bluetooth connectivity through an ESP32-S3 dual-core Tensilica LX7 microcontroller clocked at 240 MHz with vector instructions for AI acceleration.

This display offers a 320×480 resolution through the ILI9488 LCD driver, uses a 16-bit parallel interface for communication with ESP32-S3 clocked at up to 20 Mhz making it suitable for smooth graphics user interface, and the company also claims it is smooth enough for video displays, but more on that later.

Espressif Systems ESP32-S3 dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, 2.4 GHz WiFi 4 and Bluetooth 5.0 LE with support for long-range, up to 2Mbps data rate, mesh networking

Display – 3.5-inch color TFT LCD with 480×320 resolution, 16-bit parallel interface (ILI94988 driver), and capacitive touch panel (FT6263); backlight controller

The display can be programmed with the Arduino IDE. Sample code using the LovyanGFX library and EAGLE schematics and PCB layout can be found on Github. Makerfabs also designed an ESP32-S2 model that lacks Bluetooth connectivity, and the ESP32-S3 touchscreen display comes with more RAM and eMMC flash.

I was tipped about this display by Jon, a regular reader and commenter on CNX Software, who bought it, and said it works as advertised. The ESP32-S3 can really drive a high-speed display with a parallel LCD interface. However, it can’t stream video because there is no H.264 decoder, but it is great if you want a responsive GUI.

Makerfabs ESP32-S3 16-bit parallel capacitive touchscreen display is sold for $39.80 plus shipping, and the ESP32-S2 model is the same price with a resistive display, and there’s a capacitive display option for $4 more. As a side note, we previously wrote about another, smaller ESP32-S3 display, namely the LilyGO T-Display-S3, with a 1.9-inch display connected over a slower 8-bit parallel interface, and no touchscreen function that sells for around $17.

WT32-SC01 is an ESP32 Development board with a 3.5-inch color touch screen. The touch screen enables a new way of interacting with the ESP32. The board is equipped with a graphical user interface (GUI) firmware, which supports graphical drag-and-drop programming and helps users develop a customized control platform.

The TFT configuration (user setup) can now be included inside an Arduino IDE sketch providing the instructions in the example Generic->Sketch_with_tft_setup are followed. See ReadMe tab in that sketch for the instructions. If the setup is not in the sketch then the library settings will be used. This means that "per project" configurations are possible without modifying the library setup files. Please note that ALL the other examples in the library will use the library settings unless they are adapted and the "tft_setup.h" header file included. Note: there are issues with this approach, #2007 proposes an alternative method.

Support for the ESP32-S2, ESP32-S3 and ESP32-C3 has been added (DMA not supported 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:

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 library now provides a "viewport" capability. See "Viewport_Demo" and "Viewport_graphicstest" examples. When a viewport is defined graphics will only appear within that window. The coordinate datum by default moves to the top left corner of the viewport, but can optionally remain at top left corner of TFT. The GUIslice library will make use of this feature to speed up the rendering of GUI objects (see #769).

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 STM32, ESP8266 and ESP32 types. 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 is only supported with the RP2040.

"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 (55MHz with STM32 and 40MHz with ESP8266). The MHS-3.5 inch RPi ILI9486 based display is also supported.

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 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).

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.

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 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.:

The library was intended to support only TFT displays but using a Sprite as a 1 bit per pixel screen buffer permits support for the Waveshare 2 and 3 colour SPI ePaper displays. This addition to the library is experimental and only one example is provided. Further examples will be added.

An ESP32-S3 Feather board with a built in IPS TFT color display. It"s got all the features of a Feather main board, the comforting warmth of an ESP32-S3 WiFi+BLE microcontroller, and the crispness of a 240x135 pixel color TFT display.

The ESP32-S3 is a highly-integrated, low-power, 2.4 GHz Wi-Fi/BLE System-on-Chip (SoC) solution that has built-in native USB as well as some other interesting new technologies like Time of Flight distance measurements and AI acceleration. With its state-of-the-art power and RF performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.

The Feather ESP32-S3 has a dual-core 240 MHz chip, so it is comparable to ESP32"s dual-core. However, there is no Bluetooth Classic support, only Bluetooth LE. This chip is a great step up from the earlier ESP32-S2! This ESP32-S3 mini-module used on the Feather comes with 4 MB flash and 2 MB PSRAM, as well as lots of 512KB of SRAM so it"s perfect for use with CircuitPython support or any time massive buffers are needed: for fast memory access use SRAM, for slower-but-roomier access use PSRAM. It"s also great for use in ESP-IDF or with Arduino support.

The color TFT is connected to the SPI pins and uses additional pins for control that are not exposed to the breakout pads. It"s the same display as you see here, with 240x135 pixels and is IPS so you get bright color at any angle. The backlight is also connected to a separate pin so you can PWM the backlight up and down as desired.

For low power usages, the Feather has a second low-dropout 3.3V regulator. The regulator is controlled with a GPIO pin on the enable line and can shut off power to the Stemma QT port and TFT. There is also a separate power pin for the NeoPixel that can be used to disable it for even lower quiescent power. With everything off and in deep sleep mode, the TFT feather uses about 100uA of current.

ESP32-S3 Dual Core 240MHz Tensilica processor - the next generation of ESP32-Sx, with native USB so it can act like a keyboard/mouse, MIDI device, disk drive, etc!

Low Power friendly! In deep sleep mode, we can get down to 80~100uA of current draw from the Lipoly connection. Quiescent current is from the power regulator, ESP32-S2 chip, and Lipoly monitor. Turn off the NeoPixel and external I2C/TFT power for the lowest quiescent current draw.

The TFT display is a kind of liquid crystal display that is connected to each pixel using a transistor and it features low current consumption and backlight. This 2.2-inch full color LCD has a narrow PCB screen. The resolution is 320×280 pixels and it has a four-wire SPI interface and white backlight.

As you all know the are a few variants of the 1.8" TFT on the internet. With the genuine Adafruit lcd-s there are usually no problems. But when using fake ones(usually from Aliexpress) you have to make some adjustments.

Bodmers TFT_eSPI library is very awsome and rich funcionality. And the best part is that he made it to handle the pixel offsets depending on wich kind of 1.8" TFT you are using.

Then uncomment the tft height an width. And then in my case(REDTAB) uncomment for eg: #define ST7735_REDTAB. After this save it for the moment and compile sketch and upload to board. To be sure i have defined the parameters in the sketch too.This is a bit long procedure, cause you have to compile and upload the sketch every time to board untill the offset is gone, but it is worth the experimenting. For editing the h. files i strongly suggest Wordpad. Images included.
