With the Adafruit ST7735 library installed, this example can be accessed by going to examples -> Adafruit ST7735 library -> graphics test. I will explain this particular example as it features the use of the display for diverse purposes including the display of text and “animated” graphics. The second example is the graphics test example from the more capable and heavier Adafruit ST7735 Arduino library. It is one of the easiest examples that can be used to demonstrate the ability of this display. This example displays the analog value of pin A0 on the display. It can be accessed by going to examples -> TFT -> Arduino -> TFTDisplaytext. The first example is the lightweight TFT Display text example sketch from the Adafruit TFT examples. We will use two example sketches to demonstrate the use of the ST7735 TFT display. The libraries include the Adafruit GFX library which can be downloaded here and the Adafruit ST7735 Library which can be downloaded here. We will use two libraries from Adafruit to help us easily communicate with the LCD. All good? now we can proceed to the code. Schematicsĭue to variation in display pin out from different manufacturers and for clarity, the pin connection between the Arduino and the TFT display is mapped out below:ĭouble check the connection to be sure everything is as it should be. Connect the display to the Arduino as shown in the schematics below. The schematics for this project is fairly easy as the only thing we will be connecting to the Arduino is the display. The following components are needed for this tutorial:Īs usual, the exact components used for this tutorial can be bought by following the link attached to each of the components above. The goal of this tutorial is to demonstrate the abilities of the TFT to display images and text in different colors and some animation.

Current draw is based on LED backlight usage: with full backlight draw is ~50mA.2 white LED backlight, a transistor connected so you can PWM dim the backlight.5V compatible! Use with 3.3V or 5V logic.Built-in microSD slot – uses 2 more digital lines.To complement the display, it also comes with an SD card slot on which colored bitmaps can be loaded and easily displayed on the screen. The display uses the SPI protocol for communication and has its own pixel-addressable frame buffer which means it can be used with all kinds of microcontroller and you only need 4 i/o pins. The ST7735 TFT display is a 1.8″ display with a resolution of 128×160 pixels and can display a wide range of colors ( full 18-bit color, 262,144 shades!).
