tft lcd esp32 quotation
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.
This project uses the SPIFFS (ESP32 flash memory) to store images used as background. You"ll need to upload these to the ESP32 before you upload the sketch to the ESP32. For this you"ll need the ESP32 Sketch Data Upload tool.
You can download this from Github: "https://github.com/me-no-dev/arduino-esp32fs-plugin". Follow the instructions on the Github to install the tool:Download the tool archive from releases page.
Before you upload the data folder to the ESP32, you"ll first have to select the right partitioning scheme.Go to Tools -> Board and select ESP32 Dev Module.
Firstly, depending on the board you are using (with resistive touch, capacitive touch, or no touch) you will have to uncomment the correct one. For example, if you are using the ESP32 TouchDown uncomment: "#define ENABLE_CAP_TOUCH". If you are using a DevKitC with separate TFT, uncomment "#define ENABLE_RES_TOUCH".
Go ahead and upload the Bluetooth-System-Monitor.ino sketch to the ESP32. The settings under tools besides the Partition Scheme can be left to the default (see image). Go to "Sketch" and select "Upload". This may take a while because it is a large sketch.
Hola, he estado utilizando con éxito la biblioteca de TFT_eSPI en un kit de desarrollo ESP32 WROOM junto con un módulo SPI TFT LCD 240x240 basado en ST7789 en la interfaz de usuario de Arduino. La biblioteca funciona muy bien, gracias.
He cambiado a un kit de desarrollo más nuevo, el kit de desarrollo ESP32-C3-WROOM-02 que utiliza el módulo C3 más nuevo. Pero no he podido compilar el proyecto de ejemplo, por ejemplo el proyecto de Read_User_Setup. Se compila y funciona bien cuando configuro la placa en ESP32 Dev Module, pero tan pronto como cambio la placa a ESP32C3 Dev Module y cambio el puerto y la recompilo, obtengo páginas llenas de errores:

The 320*240 TFT LCD provides enough screen space to show the stock’s ticker symbol, company name, current price, price change, 52 week high/low visual, price change percent, P/E, open price, quote time, and other system related status indicators. The color of the price is either red, green, or magenta which indicates price down days, price up days, or weekends/holidays.
A possible future version would decrease the bezel around the display by creating a custom PCB to provide a TFT mount without the extra space for headers. The ESP32 and logic level converter would attach to the PCB to eliminate all but the power wires. The PCB will also allow reducing the amount the SD card protrudes from the display housing.
FreeTouchDeck uses the SPIFFS (ESP32 flash memory) to store configuration and images that are used. You"ll need to upload these to the ESP32 before you upload the sketch to the ESP32. For this you"ll need the ESP32 Sketch Data Upload tool. You can download this from Github: "https://github.com/me-no-dev/arduino-esp32fs-plugin". Follow the instructions on the Github to install the tool:
After the data folder is successfully uploaded, you can go ahead and upload the FreeTouchDeck.ino sketch to the ESP32. The settings under tools besides the Partition Scheme can be left to the default.
Note: ESP32-S2 is a relatively new product, the ecosystem and support are still fresh. We do not recommend it for beginners. Do consider NodeMCU-ESP32 or T-Display.
This is LILYGO® TTGO T8 ESP32-S2 V1.1 ST77789 1.14 Inch LCD Display WIFI Wireless Module. It operates with an ESPRESSIF-ESP32-S2chipset. ESP32-S2 is a truly secure, highly integrated, low-power, 2.4 GHz Wi-Fi Microcontroller SoC supporting Wi-Fi HT40 and having 43 GPIOs.

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. Specifications: Wireless module – ESP32-S3-WROOM-1-N16R2 with 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 16MB QSPI flash 2MB PSRAM PCB antenna Storage – MicroSD card socket Display – 3.5-inch color TFT LCD with 480×320 resolution, 16-bit parallel interface [...]
I have it up and running on my ESP8266 board but the intention is for it to have a high level GUI fuctions with a foreground and back ground like my RPi libraries that I made. This isn"t possible on the ESP8266 but is possible with the ESP32 especially with the 4MB spRAM.
This tutorial shows how to display images (.png and .jpg) in your ESP32 or ESP8266 web servers using Arduino IDE. We cover how to embedded images in an asynchronous web server using the ESPAsyncWebServer library or in a simple HTTP server.
SPIFFS stands for Serial Peripheral Interface Flash File System and it is a lightweight filesystem created for microcontrollers with a flash chip like the ESP32 and ESP8266.
To upload images to the ESP32 and ESP8266 flash memory, we’ll use a plugin for Arduino IDE: Filesystem uploader. Follow one of the next tutorials to install the filesystem uploader depending on the board you’re using:
This section shows how to display an image stored in the ESP32 or ESP8266 flash memory in a web server using the ESPAsyncWebServerlibrary. To build this web server, you need to install the following libraries:
Create a new sketch in Arduino IDE and copy the following code. This code works both with the ESP32 and ESP8266. It includes the proper libraries depending on the board you’re using.
Then, in your Arduino IDE, upload the images to your board. Go to the Toolsmenu and select “ESP32 Sketch Data Upload” or “ESP8266 Sketch Data Upload” depending on the board you’re using.
When it receives a request on /sun URL, we send the image that is stored on the /sun.png path in the ESP32/ESP8266 SPIFFS (filesystem) and it is of type image/png.
This section shows how to convert your images to base64 to include them in the ESP32/ESP8266 web server. We’ll show you how to display images in an asynchronous web server and in a simple HTTP server.
In this article we’ve shown you different ways to display images in your ESP32/ESP8266 web servers. If you know any other suitable method, you can share it by writing a comment below.
