adafruit 1.44 color tft lcd made in china

This lovely little display breakout is the best way to add a small, colorful and bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available!

The 1.44" display has 128x128 color pixels. Unlike the low cost "Nokia 6110" and similar LCD displays, which are CSTN type and thus have poor color and slow refresh, this display is a true TFT! The TFT driver (ST7735R) can display full 16-bit color using our library code.

The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as a ultra-low-dropout 3.3V regulator and a 3/5V level shifter so you can use it with 3.3V or 5V power and logic. We also had a little space so we placed a microSD card holder so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card. The microSD card is not included, but you can pick one up here.

The TFT display is a kind of liquid crystal LCD that is connected to each pixel using a transistor, and it features low current consumption, high-quality, high-resolution and backlight. This 1.44-inch full color LCD has a narrow PCB display. The resolution is 128×128 pixels, and it has a four-wire SPI interface and a white backlight.

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).

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.

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 project is a microcontroller board, based on an ATtiny414, that can accommodate a range of different Adafruit and AliExpress colour TFT displays:

It"s ideal for use with my Tiny TFT Graphics Library 2, and includes an I2C interface and optional crystal, making it suitable for use in sensor and clock projects.

While working on my Tiny TFT Graphics Library I needed to test it with several different TFT displays on a prototyping board, and noticed that many of them, with a small number of exceptions, had one of two standard pin connection layouts. That gave me the idea of designing a breakout board that would take any of these displays, and be a great starting point for a variety of display-based projects.

The board accommodates any of a variety of Adafruit or AliExpress colour TFT displays – for details see the tables below. The display connection header pin holes are staggered so you can push the display in place, and it will stay firmly connected without soldering. This is especially useful if you want to try different displays in an application.

Although you could drive these TFT displays from an 8-pin ATtiny processor such as the ATtiny402, I decided to base the board on a 14-pin device, such as the ATtiny414, to allow it to offer the following additional optional features:

Use the 11-way row of pins for Adafruit displays. Note that a couple of Adafruit TFT displays have an incompatible pinout; if you"re not sure whether your display is compatible check that it has the following 11-way pin header:

The Adafruit displays all include an LDO 3.3V regulator and logic-level translation, so can be safely interfaced to processors powered from either 5V or 3.3V. They also include an SD-card socket, and a separate SDCS select line for the SD card.

The processor can be any of the 0-series, 1-series, or 2-series ATtiny range in a 14-pin SOIC package, from the ATtiny404 to the ATtiny3224, but note that the timer crystal is only supported by a 1-series or 2-series device. They are all software compatible, so the same program will work on any of them. My Tiny TFT Graphics Library 2 needs more than 2Kbytes so I don"t recommend using the ATtiny204 or ATtiny214, which only have 2Kbytes of program memory.

If you want to control the backlight, or use the SD-card socket on the Adafruit displays, fit 0Ω resistors in the appropriate positions to act as links. Alternatively PA5 and PA6 are available on header pins D1 and D2 for other uses.

The Universal TFT Display Backpack is ideal for use with my Tiny TFT Graphics Library 2, which is optimised for use with ATtiny microcontrollers such as the ATtiny414. You could also use my Compact TFT Graphics Library which uses standard Arduino SPI routines, but I"m not sure why you would want to as it"s not as fast as the Tiny TFT library.

Then upload the program to the Universal TFT Display Backpack using a UPDI programmer. The recommended option is to use a USB to Serial board, such as the SparkFun FTDI Basic board

I"ve got a chinese 1.44" TFT - very similar to AdaFruit"s. In fact, I think it"s the same and the Adafruit ST7735 library works great with it right away.

Upon some googling I came across the PDQ GFX library, it claims to be a drop-in replacement for Adafruit"s but much better optimized. So I use that in my sketch now. I thing it"s a bit better with this library, but not much.

Note that my project requires drawing complex geometry across the whole screen, and optimizing its re-draw (e. g. only updating the pixels that actually changed) will not be feasible because Arduino Uno lacks the RAM required for that (calculating diff between two frames, even in 1-bit color).
