Unfortunately the u8g2 library doesn’t support this display, though it does support many of the Sitronix boards. I have yet to find another library to use with this display, though there are a couple other vendors for the board itself on Amazon. It’s unclear whether the issue is the library or the board, however. The DFRobot_ST7687S library has slow refresh rate on the ST7687S board. It does not support the DFRobot ST7867S board, however. The Adafruit_ST7735/7789 library and Adafruit_GFX library works well with some of the Sitronix boards above. Display manufacturers like Ilitek and Sitronix do not appear to release their own libraries for their displays. As with other types of displays, a well-supported library like the Adafruit libraries makes the display worth more, but limits you to the types of displays that vendor offers. Vendors tend to support the displays they make in their own breakout boards, and not others. There’s no standard library for TFT screens, unfortunately.

Tinkersphere breakout board for this display.

It works with the Adafruit_ST7789 library, but you have to change the init() function to include the SPI mode like so:

MakerFocus 1.3” LCD Display, no MicroSD, Amazon link - This display does not have a CS pin, so it can’t be used with other SPI devices at the same time.

Adafruit 1.54” ST7789 Display with MicroSD.

Adafruit 1.44” ST7735R display with MicroSD Breakout.

Adafruit 1.8” ST7735R display with MicroSD Breakout.

Sitronix ST7735 and ST7789 TFT DisplaysĪll of the displays listed below have been tested with the Adafruit_ST7735/ST7789 libraries and the Adafruit_GFX library, with the modifications mentioned below. For this board and others like it, initializing them with SPI_MODE3 works. Some displays, like MakerFocus’ 1.3” TFT, do not implement the CS pin. Most TFT displays tend to have an SPI interface, with some extra pins, as explained on the main page of this repo. The TFT boards I have encountered so far have had either Sitronix or Ilitek interfaces. Other libraries don’t include a canvas, but you can draw a filled rectangle over part of the screen and then draw on top of it, as shown in this example for the ILI9225. It doesn’t speed up the display, but it can simplify drawing a subset of the screen.

Adafruits GFX library includes a Canvas class, which lets you update elements offscreen and then draw them. Therefore, it’s sometimes usefil to draw only part of the display at once. You can find the code examples at this link.

Most libraries for color TFT displays implement the usual 24-bit RGB color space, where 0xFF0000 is red, 0x00FF00 is green, and 0x0000FF is blue.

TFT displays are high resolution and full color, unlike the OLED or ePaper displays mentioned in this repository.

#Tft displays drivers#

There are a few common TFT display drivers on the electronics hobbyist market, and a handful of libraries that work with them. This project is maintained by tigoe TFT LCD Displays A collection of examples for driving displays from microcontrollers
