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. Note: some people find issues with this display when trying to read from the SD card. Logo = TFTscreen.loadImage(' arduino.bmp') Replace the “ arduino.bmp” with the name of your image: // now that the SD card can be access, try to load the image file bmp format.Ĥ) Copy the image to the SD card and insert it on the SD card slot at the back of the display.ĥ) Wire the SD card pins to the Arduino by following the table below: SD card on TFT displayīoth the display and the SD card work with SPI communication, so you’ll have pins on the Arduino with two connections.Ħ) In the Arduino IDE go to File > Examples > TFT > Arduino > TFTBitmaLogo.ħ) Edit the code, so that it searches for your image.

To do that, you can use a photo editing software and save the image as. There are four pins opposite to the display pins, as shown in figure below.Ģ) The display can load images bigger or smaller than the display size (160 x 128 px), but for better results, edit your image size to 160 x 128 px.ģ) The image should be in. Follow the next steps to display an image on the display:ġ) Solder header pins for the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. The 1.8 TFT display can load images from the SD card. Here’s the shapes on the display: Display images wait 200 miliseconds until change to next figure

Every time the code goes through the loop, the shapes change color. The following example displays several shapes. circle(x, y, radius) – draws a circle with center at (x, y) with the specified radius rect(xStart, yStart, width, height) – draws a rectangle with the top left corner at (xStart, yStart) with the defined width and height

line(xStart, yStart, 圎nd, yEnd) – draws a line that starts at (xStart, yStart) and ends at (圎nd, yEnd) point(x, y) – display a point at the (x, y) coordinate The TFT library provides useful functions to draw shapes on the display: Here’s your “Hello, World!” text on the 1.8 TFT display. wait 200 miliseconds until change to next color print Hello, World! in the middle of the screen TFTscreen.stroke(redRandom, greenRandom, blueRandom) clear the screen with a black background The following example displays “Hello, World!” in the middle of the screen and changes the font color every 200 miliseconds.Ĭopy the following code to your Arduino IDE and upload it to your Arduino board. 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. You can increase or decrease the number given as argument, to increase or decrease font size.įinally, to draw text on the display you use the following line: TFTscreen.text(' Hello, World!', x, y) To choose font color: TFTscreen.stroke( r, g, b) In which, r, g and b are the RGB values for a given color.

To set the background color, use: TFTscreen.background( r, g, b) To write text on the display, you can customize the screen background color, font size and color. Then, you need to define the CS, A0 (or DC) and RST pins: #define cs 10 #define dc 9 #define rst 8Ĭreate an instance of the library called TFTscreen: TFT TFTscreen = TFT(cs, dc, rst) įinally, in the setup(), you need to initialize the library: TFTscreen.begin() Display text We also use the TFT library to write and draw on the display. The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. If you’re using another Arduino board, check the Arduino official documentation. Note: different Arduino boards have different SPI pins. The table below shows the 1.8 TFT wiring to Arduino UNO. You can use the preceding links or go directly to /tools to find all the parts for your projects at the best price! You can get the 1.8 TFT display for approximately $3 – check prices on Maker Advisor. To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later. This module uses SPI communication – see the wiring below. The following figure shows the screen front and back view. The display can load images from an SD card – it has an SD card slot at the back. The 1.8 TFT is a colorful display with 128 x 160 color pixels.

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