In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

In which “Hello, World!” is the text you want to display and the (x, y) coordinate is the location where you want to start display text on the screen.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

Note: some people find issues with this display when trying to read from the SD card. We don’t know why that happens. In fact, we tested a couple of times and it worked well, and then, when we were about to record to show you the final result, the display didn’t recognized the SD card anymore – we’re not sure if it’s a problem with the SD card holder that doesn’t establish a proper connection with the SD card. However, we are sure these instructions work, because we’ve tested them.

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.

The card - being a shield - means you can just line up the pins on the board to the mount holes on the Arduino, and the card pushes firmly into place.

The build quality is excellent - the surface mount chips are all soldered well, the display is mounted cleanly on the PCB. You even get a little plastic stylus for the capacitive touchscreen.

Warning! You might need to power your Arduino board along with the USB power. I found my little laptop couldn"t power the bright white screen LED"s, RGB screen, and Arduino all at the same time. The Arduino would repeatedly "unplug", and then "replug".

For reference, I did create the Waveshare_ILI9486 wrapper library which has been tested on the UNO/Mega with genuine Waveshare SPI shift-register based displays (including a basic GFX-style interface). As David points out, it is possible that your board may work with a Waveshare-style driver. Note that I have not yet tested the above library on any of the RPI board variants (so anshumantech"s test result is not surprising). I don"t recall seeing a schematic or know how the RPI A,B,C variants may differ, but assuming it is still ILI9486-based via 16b shift regs, perhaps some small tweaks to the library or pin connectivity might enable it to work.
