esp8266 2.4 tft lcd manufacturer

The ILI9341 TFT module contains a display controller with the same name: ILI9341. It’s a color display that uses SPI interface protocol and requires 4 or 5 control pins, it’s low cost and easy to use.

The resolution of this TFT display is 240 x 320 which means it has 76800 pixels. This module works with 3.3V only and it doesn’t support 5V (not 5V tolerant).

The ILI9341 TFT display board which is shown in project circuit diagram has 14 pins, the first 9 pins are for the display and the other 5 pins are for the touch module.

Pins D5 (GPIO14) and D7 (GPIO13) are hardware SPI module pins of the ESP8266EX microcontroller respectively for SCK (serial clock) and MOSI (master-out slave-in).

The first library is a driver for the ILI9341 TFT display which can be installed from Arduino IDE library manager (Sketch —> Include Library —> Manage Libraries …, in the search box write “ili9341” and choose the one from Adafruit).

The ILI9341 TFT display is connected to NodeMCU hardware SPI module pins (clock and data), the other pins which are: CS (chip select), RST (reset) and DC (data/command) are defined as shown below:

I have tried david_prentice"s MCUFRIEND_kbv Library with some hacks to no avail. I tried to hack the library for ESP8266 (updated write_8 and read_8 functions in mcufriend_sheild.h and defined SUPPORT_4532) - using these connections

This person ( (146) ESP8266 and 2.4" 8-bit parallel ST7781 TFT Uno Shield - YouTube) got the same display working w/ nodeMCU (albeit their module is 5V one and has hack on the LDO).

The Bodmer/TFT_eSPI: Arduino and PlatformIO IDE compatible TFT library optimised for the Raspberry Pi Pico (RP2040), STM32, ESP8266 and ESP32 that supports different driver chips (github.com) library says 8 bit parallel is not possible w/ ESP8266 because of shortage of GPIOs - but ESP8266 has 16 GPIOs (out of which 4 are SPI). I don"t plan on using touch or SD card functionality anyways. The LCD requires 8(data) + 4 (Control) + 1 = 13 pins, which should fit in the 16 provided by ESP8266 ? Please let me know if I am missing anything.

Anyways - the first question at hand would be - is it possible to run 8 bit parallel tft w/ ESP8266, followed by - which library can do the job if possible.

ILI9341 is a 262,144-color single-chip SOC driver for a-TFT liquid crystal display with resolution of 240RGBx320 dots, comprising a 720-channel source driver, a 320-channel gate driver, 172,800 bytes GRAM for graphic display data of 240RGBx320 dots, and power supply circuit. ILI9341 supports parallel 8-/9-/16-/18-bit data bus MCU interface, 6-/16-/18-bit data bus RGB interface and 3-/4-line serial peripheral interface (SPI). The moving picture area can be specified in internal GRAM by window address function. The specified window area can be updated selectively, so that moving picture can be displayed simultaneously independent of still picture area.

You can find ILI9341-based TFT displays in various sizes on eBay and Aliexpress. The one I chose for this tutorial is 2.2″ length along the diagonal, 240×320 pixels resolution, supports SPI interface, and can be purchased for less than $10.

Note that we will be using the hardware SPI module of the ESP8266 to drive the TFT LCD. The SPI communication pins are multiplexed with I/O pins D5 (SCK), D6 (MISO), and D7 (MOSI). The chip select (CS) and Data/Command (DC) signal lines are configurable through software.

For ILI9341-based TFT displays, there are some options for choosing the library for your application. The most common one is using Bodmer. We will use this library in this tutorial. So go ahead and download the

The library contains proportional fonts, different sizes can be enabled/disabled at compile time to optimise the use of FLASH memory. The library has been tested with the NodeMCU (ESP8266 based).

The library is based on the Adafruit GFX and Adafruit ILI9341 libraries and the aim is to retain compatibility. Significant additions have been made to the library to boost the speed for ESP8266 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 a significant number of example sketches to demonstrate the different features.

Configuration of the library font selections, pins used to interface with the TFT and other features is made by editting the User_Setup.h file in the library folder. Fonts and features can easily be disabled by commenting out lines.

Now you are all set to try out tons of really cool built-in examples that come with the library. The following output corresponds to the TFT_Pie_Chart example.

My favorite example is TFT terminal, which implements a simple “Arduino IDE Serial Monitor” like serial receive terminal for monitoring debugging messages from another Arduino or ESP8266 board.

In the previous article (“WiFi OLED Mini Weather Station with ESP8266“) I have used the OLED kit from https://blog.squix.org. And as promised, this time it is about the “ESP8266 WiFi Color Display Kit”:

I had ordered both because I thought that the Color Display kit is needs the other kit as a base. Well, it turned out that both kits work independently. My bad. Actually this is good, as I have now two independent ESP8266 weather stations :-). An addition to that, they can exchange data (e.g. temperature/humidity) with a server, so that makes them a perfect dual weather station.

Example code is available on GitHub (https://github.com/squix78/esp8266-weather-station-color). The code is very well documented I had no issues to make all the needed configuration (WiFi SSID and connection settings). After a few  hours I had the ESP8266 weather station up and running in the first prototype of the enclosure:

After a few hours, I have now my second ESP8266 WiFi weather station with touch LCD. It is not looking good and I very much enjoy it. The design is available on Thingiverse (https://www.thingiverse.com/thing:2527282).

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.

You have an 8-bit parallel interface TFT display. It requires 13 GPIO pins - D0-D7 plus reset, chip select, read, write and register select. You can forego the "read" signal and tie it high to save a pin. You can probably do the same with the reset signal, meaning you need a minimum of 11 pins.

Simply put: that TFT requires a lot of GPIO pins - 10 at an absolute bare minimum, but better if you have more available. The ESP8266 doesn"t have many IO pins - and some of them are very sensitive about what they can be connected to without affecting the boot process.

This case is made for a 2.4" TFT screen with touch panel. The design is pretty similar to my other design which uses a smaller 2.2" screen instead: https://www.thingiverse.com/thing:2832880
