2.2 serial spi tft color lcd module free sample

ER-TFT022-1 is 240x320 dots 2.2" color tft lcd module display with ILI9341 controller,optional capacitive touch panel with controller FT6236U and resistive touch panel,superior display quality,super wide viewing angle and easily controlled by MCU such as 8051, PIC, AVR, ARDUINO ARM and Raspberry PI.It can be used in any embedded systems,industrial device,security and hand-held equipment which requires display in high quality and colorful image.It supports 8080 8-bit,9-bit,16-bit,18-bit parallel,3-wire,4-wire serial spi interface. FPC with zif connector is easily to assemble or remove.Lanscape mode is also available.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".Here is the link for 2.2"TFT Shield with Libraries, Examples.Schematic Diagram for Arduino Due,Mega 2560 and Uno.For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and Development Kit at the bottom of this page.

7 fonts and graphic engine embedded, touch screen and flash chip drivers embedded(if touch screen or 2 to 16MB flash chip installed), custom fonts can be downloaded to the module"s flash.

High level commands set (61 commands total) are easy to remember and understand, eg.: send 5 bytes: "CCabc" will draw a ratio=c pixels circle at coordinate (a,b) on the screen; 5 bytes "DNALL" will put the module to sleep mode(<0.1mA), and more...

TFT LCD module has always been one of the hot products in DIY industry and LCD is basically the necessary products during all projects, at the same time, serial port modules are also the popular ones, because it takes few IO and the usage is simple. This section of the 2.2 inch TFT LCD serial SPI integrated features of compact, SPI interface.

The LCD drive ic is ILI9341. It"s a 240 * 320 (resolution), 2.2 inch TFT LCD screen. The LCD has a wide viewing angle, the contrast is also very suitable.

This 2.2-inch LCD module with a resolution of 240X320. It only requires 5 IOs to lighten the display, or a direct hardware serial peripheral interface that can be driven. LCD color screen display has SMT reflow and industrial control quality, which can work stably for a long time.

The ST7789 TFT module contains a display controller with the same name: ST7789. It’s a color display that uses SPI interface protocol and requires 3, 4 or 5 control pins, it’s low cost and easy to use. This display is an IPS display, it comes in different sizes (1.3″, 1.54″ …) but all of them should have the same resolution of 240×240 pixel, this means it has 57600 pixels. This module works with 3.3V only and it doesn’t support 5V (not 5V tolerant).

The ST7789 display module shown in project circuit diagram has 7 pins: (from right to left): GND (ground), VCC, SCL (serial clock), SDA (serial data), RES (reset), DC (or D/C: data/command) and BLK (back light).

As mentioned above, the ST7789 TFT display controller works with 3.3V only (power supply and control lines). The display module is supplied with 3.3V (between VCC and GND) which comes from the Arduino board.

To connect the Arduino to the display module, I used voltage divider for each line which means there are 4 voltage dividers. Each voltage divider consists of 2.2k and 3.3k resistors, this drops the 5V into 3V which is sufficient.

The first library is a driver for the ST7789 TFT display which can be installed from Arduino IDE library manager (Sketch —> Include Library —> Manage Libraries …, in the search box write “st7789” and install the one from Adafruit).

This is a quick video showing our new 1.3 inch TFT LCD. This is a small, full-color TFT. It"s controlled via 4-wire SPI. It has a ST7789H2 controller. This display runs off a single 3.3v supply which controls the logic and backlight.
