2.8”320x240 TFT LCD Resistive Touchscreen Breakout Wiki - DFRobot

Introduction

This is a 2.8” TFT Resistive Touchscreen Display. The module, with a resolution of 320x240, adopts ILI9341 as driver IC and SPI (4-line) communication mode. The board integrates touch chip XPT2046, which converts the touch data collected by the AD to SPI data. The module also integrates an SD card slot allowing you to easily read the full-color bitmap. There are two modes of wiring supplied, normal pin header wiring and GDI. The latter one requires to work with a main controller board with a GDI interface (e.g. FireBeetle-M0). You can use it with only one FPC line plugging in, which reduces the complexity of the wiring. Furthermore, it features high resolution, wide viewing angle, and simple wiring, which can be used in all sorts of display applications, such as, IoT controlling device, game console, desktop event notifier, touch interface, etc.

Num Label Description
1 VCC Positive Pole
2 GND Negative Pole
3 SCLK Clock
4 MOSI Data (from host to slave)
5 MISO Data (from slave to host)
6 CS Chip Selection
7 RES Restoration
8 DC Data/Command
9 BL Backlight. The backlight is set to the default value, and the user can light up without connecting the backlight pin; in addition, when the backlight pin is connected, input high level (1) to adjust the backlight brightness to the maximum, input low level (0) to turn off the backlight

11 INT Interrupt
12 SDCS SD Card Chip Selection

Tutorial

This product is Breakout module with SPI communication mode and GDI interface, which reduces the wiring complexity and makes it easy to display what was read from the SD card.

Note
1. The GDI interface should be used in conjunction with the main control board with GDI interface
2. It is recommended to use Arduino 1.8.10 and above
3. If the SD card slot is in poor contact, it may fail to initialize. Try agian after unplugging and plugging

Requirements

This is UI control demo -- digital keyboard. At the start, click the textbox, and click the number after the cursor shows in the textbox. The corresponding number will be shown in the textbox. The "x" at the bottom right corner is used to delete the context in the textbox.

Note: Due to the limited memory capacity of Arduino UNO, it is unable to run programs related to UI. Therefore, we recommend using ESP32, which has more memory, for such operations.
