CYD ESP32 2.8 Inch Resistive Touch Display

The CYD E32R28T is a compact 2.8-inch display module powered by an ESP32-WROOM-32E. It features a 240×320 resistive touchscreen driven by the ILI9341 or in some of the newer displays the ST7789, supports 262K colors, and offers rich connectivity including SPI peripherals, audio output, MicroSD storage, USB-C, RGB status LED, lithium battery support, and reliable power management for portable applications.

Board Layout

Quick Setup

Step 1 – Add ESP32 Board Support for Arduino IDE

Open File -> Preferences and add this URL to Additional Boards Manager URLs:
https://espressif.github.io/arduino-esp32/package_esp32_index.json

Step 2 – Boards Manager

Open Tools → Board → Boards Manager, search for esp32, and install:
ESP32 by Espressif Systems

Step 3 – Library Manager

Open Sketch → Include Library → Manage Libraries, search for TFT_eSPI, and install the library.

Step 4 – Configure User_Setup.h file

Locate and edit User_Setup.h inside the TFT_eSPI library to match the E32R28T display configuration.

Make sure the following definitions are uncommented in User_Setup.h file

Section 1. 

#define ILI9341_DRIVER // Generic driver for common displays ILI9341V

Please not some of the newer boards use the ST7789 chipset 

Section 2. Define the pins that are used to interface with the display here

#define TFT_BL 21 // LED back-light control pin

// For ESP32 Dev board (only tested with ILI9341 display)

#define TFT_MISO 12

#define TFT_MOSI 13

#define TFT_SCLK 14

#define TFT_CS 15 // Chip select control pin

#define TFT_DC 2 // Data Command control pin

#define TFT_RST -1 // Set TFT_RST to -1 if display RESET is connected to ESP32 board RST

Special Note

The E32R28T display does not use standard SPI pin assignments.

If you prefer not to edit the User_Setup.h file the following definitions can be added to the top of your program

#define TFT_BL 21 // LED back-light control pin

#define TFT_MISO 12

#define TFT_MOSI 13

#define TFT_SCLK 14

#define TFT_CS 15 // Chip select control pin

#define TFT_DC 2 // Data Command control pin

#define TFT_RST -1 // Reset is handled by ESP32 

Section 2. Define the pins that are used to interface with the display here

#define TFT_BL 21 // LED back-light control pin

For more information about Pin Assignments for the E32R28T see Pin Asignments in Resources

Sample Code

This example will only work if User_Setup.h is correctly updated by display driver and pins

Contributions

• Thank you to our client, Mr Clive Gerber, for highlighting that older CYD modules use the ILI9341 display controller, while newer versions use the ST7789.
