In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

The next example is controlling an RGB LED using these three RGB sliders. For example if we start to slide the blue slider, the LED will light up in blue and increase the light as we would go to the maximum value. So the sliders can move from 0 to 255 and with their combination we can set any color to the RGB LED,  but just keep in mind that the LED cannot represent the colors that much accurate.

The third example is a game. Actually it’s a replica of the popular Flappy Bird game for smartphones. We can play the game using the push button or even using the touch screen itself.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

As the code is a bit longer and for better understanding I will post the source code of the program in sections with description for each section. And at the end of this article I will post the complete source code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

Next we need to define the fonts that are coming with the libraries and also define some variables needed for the program. In the setup section we need to initiate the screen and the touch, define the pin modes for the connected sensor, the led and the button, and initially call the drawHomeSreen() custom function, which will draw the home screen of the program.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

Next is the distance sensor button. First we need to set the color and then using the fillRoundRect() function we will draw the rounded rectangle. Then we will set the color back to white and using the drawRoundRect() function we will draw another rounded rectangle on top of the previous one, but this one will be without a fill so the overall appearance of the button looks like it has a frame. On top of the button we will print the text using the big font and the same background color as the fill of the button. The same procedure goes for the two other buttons.

Now we need to make the buttons functional so that when we press them they would send us to the appropriate example. In the setup section we set the character ‘0’ to the currentPage variable, which will indicate that we are at the home screen. So if that’s true, and if we press on the screen this if statement would become true and using these lines here we will get the X and Y coordinates where the screen has been pressed. If that’s the area that covers the first button we will call the drawDistanceSensor() custom function which will activate the distance sensor example. Also we will set the character ‘1’ to the variable currentPage which will indicate that we are at the first example. The drawFrame() custom function is used for highlighting the button when it’s pressed. The same procedure goes for the two other buttons.

So the drawDistanceSensor() custom function needs to be called only once when the button is pressed in order to draw all the graphics of this example in similar way as we described for the home screen. However, the getDistance() custom function needs to be called repeatedly in order to print the latest results of the distance measured by the sensor.

Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.

Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.

In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work  you can check my particular tutorial. Here you can download that file:

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.

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:

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.

A close look at the video input interfaces used in LCD monitors. With the emergence of a new generation of interfaces, growing numbers of LCD monitors feature multiple and different interfaces. Image quality and ease of use are likely to depend on how well the user knows and uses the unique characteristics of each interface when connecting the appropriate devices.

Note: Below is the translation from the Japanese of the "IT Media LCD Display Course II, Part 2," published on December 16, 2008. Copyright 2011 ITmedia Inc. Information about Mini DisplayPort was added to the English translation.

Driven by demand for higher-resolution monitor environments and the proliferation of high-definition devices, the types of video input interfaces ("interfaces" hereinafter) found in LCD monitors continue to proliferate. More than likely, significant numbers of users encountering LCD monitors incorporating multiple input systems have wondered what to connect to which terminal. In this article, we"ll discuss, one by one, the main interfaces used today. But first, let"s give an overview of the types of interfaces available.

The interfaces for LCD monitors designed for use with PCs can be grouped into two categories: analog interfaces, carryovers from the days of CRT monitors, and the digital interfaces developed more recently. An analog interface involves the additional steps of conversion of digital signals within the PC to analog signals for output and the conversion of these analog signals back into digital form by the LCD monitor receiving the signal. This series of actions can degrade image quality. (Image quality also depends on the quality of the route used in converting from analog to digital.) A digital interface offers superior image quality, since it transmits digital signals without conversion or modification.

LCD-monitor interfaces also can be grouped by differences in the devices connected. Major categories here are inputs from PCs and inputs from audio-video (AV) devices. PC input generally involves one of the following five interface types: D-Sub for analog connections; DVI-D for digital connections; DVI-I, which is compatible with both analog and digital connections; and HDMI and DisplayPort, representing the new generation of interfaces for digital connections. Other more recent adapters input and output PC RGB signals and LCD monitors using USB as a video input interface.

The main AV input interfaces are composite video, S-Video, component video, D1 – 5, and HDMI. All of these other than the new HDMI standard use analog connections. As with PC input, a digital HDMI connection generally provides better image quality for AV input than the various analog connection interfaces.

It"s worth noting that while HDMI was designed for use with AV input and output, the standard also supports PC input and output. LCD monitors incorporating HDMI ports include some that support PC input officially and others that—whether or not they can display PC input—do not support PC input officially.

Known officially as D-Sub miniature, D-Sub is not exclusive to display use. It"s also used for serial-port, parallel-port, SCSI, and other connectors, with the number of connector pins depending on the purpose of use. However, these connector standards are rarely if ever found in PCs now for general-purpose personal use, most such applications having migrated to USB.

When used as a monitor interface, a D-Sub port is also known as a VGA port, an analog connection standard that"s been around for some time. The connector is a DE-15 connector with 15 pins in three rows, often referred to as a "mini-D-Sub 15-pin" or "D-Sub 15-pin" connector. (Some connectors omit unused pins.) D-Sub is currently the most widely used monitor interface, compatible with very large numbers of PCs and LCD monitors.

A D-Sub female connector (photo at left) installed on the monitor side and a D-Sub male connector (center photo) on the cable side. A D-Sub cable features a screw on each end of the connector that can be turned by hand to prevent unintended disconnection (photo at right).

The Digital Visual Interface (DVI) standard uses one of three types of connectors: DVI-D for digital connection; DVI-A for analog connection; and DVI-I, compatible with both digital and analog connections. The DVI-A connector for analog use is not in general use and can be disregarded when choosing monitor products.

Keep in mind that there are two types of mainstream DVI-D digital connections: single link and dual link. For a single-link DVI-D connection, the maximum resolution that can be displayed is 1920 × 1200 pixels (WUXGA). Higher resolutions (such as 2560 × 1600 pixels) require a dual-link DVI-D connection providing double the bandwidth of a single-link DVI-D (7.4 Gb/second or higher). To use a dual-link DVI-D connection, the DVI-D input on the LCD monitor side, the DVI-D output on the PC side, and the DVI-D cable must all be compatible with the dual-link DVI-D standard.

DVI-I, the other DVI standard, can be used with both digital and analog connections, depending on the monitor cable used. Since a DVI-I analog signal is compatible with the D-Sub standard, an analog connection can be formed by using a monitor cable with a D-Sub connector on one end and a DVI-I connector on the other. Depending on the cable and the connectors on the PC side and on the LCD-monitor side, it may also be possible to use an adapter for connecting a DVI-I connector with a D-Sub connector.

Monitor cables with DVI-I connectors on both ends were available at one time. These are rare today, since this configuration made it difficult to determine whether the connection was digital or analog and generated frequent connection issues. Having DVI-I connectors on both the PC side and the LCD monitor side can lead to confusion. In such cases, the ideal configuration is a digital connection made with a DVI-D cable.

The HDMI, DisplayPort, and Mini DisplayPort standards also are compatible with the High-Bandwidth Digital Content Protection System (HDCP). A technology intended to protect copyright on digital content, HDCP allows authorization of both output and input devices before video is displayed.

Another feature is that HDMI, DisplayPort, and Mini DisplayPort video signals can be converted back and forth with the DVI-D standard, a PC digital interface. Using the appropriate conversion adapter or cable, we can output video from a DVI-D, HDMI, DisplayPort, and Mini DisplayPort connector and input to any of these options. Currently, however, this implementation appears to be imperfect: In certain cases, input and output devices are not completely compatible (i.e., video does not display).

While HDMI, DisplayPort, and Mini DisplayPort each can transmit both audio and video using a single cable, DVI-D can transmit only video and requires separate input/output ports and cables for audio. For this reason, when converting between the DVI-D and HDMI, DisplayPort or Mini DisplayPort standards, only video can be transmitted over a single cable. (Some products can transmit audio from the DVI side via a conversion adapter.)

Now a standard interface for devices (primarily televisions and recorders), HDMI was established in December 2002 by Sony, Toshiba, Thomson Multimedia, Panasonic (formerly Matsushita), Hitachi, and Philips, led by Silicon Image. HDMI video signals are based on the DVI-D standard, a digital RGB interface used in PCs, to which audio transmission and digital rights management (DRM) functions were added. HDMI was intended mainly for use as a digital video and audio interface for home electronics and AV equipment.

HDMI cables come in two types: Standard (category 1), denoting those that have passed 74.25 MHz in transmission-speed tests, and High Speed (category 2), denoting those certified for 340 MHz. A High Speed cable is recommended when using high-definition signals such as 1440p.

Incidentally, while HDMI 1.3 incorporates standards such as the wide color-gamut standard xvYCC and Deep Color, which can handle color data at greater than 24 bits, these specifications are elective. A version number such as 1.3 is merely the number of the applicable technical specifications; manufacturers can choose what functions to include, depending on the specific product. For this reason, even a product advertised as HDMI 1.3a compliant may not feature all of the functions supported by HDMI 1.3a.

Formally approved in May 2006, the DisplayPort standard is a new standard released in May 2005 by the Video Electronics Standards Association (VESA) of the United States, an industry organization that establishes standards for PC-related interfaces. As a video interface promoted by VESA, a constituency composed mainly of PC and monitor makers, it is designed to succeed the DVI and D-Sub standards as a PC interface. However, there"s no reason it can"t also be used in AV equipment.

With a maximum transmission speed of 10.8 Gbps, compatibility with resolutions of up to 2560 × 2048 pixels or higher, color depth of 48 bits (16 bits per RGB color), and a maximum refresh rate of 120 Hz (120 fps), its basic video interface specs are close to those of HDMI. However, unlike HDMI, which transmits data for RGB video signals and clock signals separately, it sends all video and audio to the destination device through a serial connection, split into micro-packets called transfer units.

Since DisplayPort is a serial interface like PCI Express that generates a clock from the data instead of using external clock signals, data transmission speeds and functionality are easily improved. In addition, since DisplayPort employs a configuration wherein the LCD monitor is operated directly, it makes it possible to reduce the numbers of components. Another benefit is its ability to transmit signals over distances of up to 15 meters.

In the DisplayPort standard, the output side is defined as the source device and the input side as the sync device. Under this configuration, the source and sync devices communicate with each other, making it possible to automatically adjust transmission to the optimal resolution, color depth, and refresh rate. Audio and video data can be transmitted through a combination of single, double, or quadruple channels called lanes, and two data rates (1.62 Gbps and 2.7 Gbps). The minimum configuration is a single lane at 1.62 Gbps; the maximum is four lanes at 2.7 Gbps each for a total of 10.8 Gbps.

The audio formats supported and other attributes are important elements of sync devices. For audio, compatibility with 16-bit linear PCM (32/44.1/48 kHz) is required. Other formats are optional. Still, the standard is compatible with formats up to high-definition audio such as Dolby TrueHD and DTS HD. For color information, compatibility with RGB, YCbCr (4:2:2), and YCbCr (4:4:4) is a requirement.

One major difference apparent when we compare HDMI and DisplayPort is the presence or absence of licensing fees. Implementing HDMI in a product requires manufacturers to pay a licensing fee of $10,000/year, while HDCP implementation requires a separate licensing fee of $15,000/year. These licensing fees entail significant costs for manufacturers. When product pricing reflects these costs, they can impact ordinary users to a greater or lesser degree. A more familiar example is the HDMI cable, which is also subject to a licensing fee, making it more expensive than other AV cables. (Note that the licensing fee is not the sole cause of higher prices; quality requirements and other factors also drive up prices.)

DisplayPort requires no licensing fees other than that for HDCP, making it more attractive and easier for manufacturers to adopt. Progress in mass production will likely lead to price advantages for ordinary users as well. Still, HDMI is clearly the current mainstream digital interface for products like AV equipment and videogame consoles. DisplayPort, even if standardized under the leadership of PC makers, is unlikely to take its place. With growing support for DisplayPort among vendors of graphics chips for use in PC environments and growing numbers of compatible products, including the MacBook, use of DisplayPort is projected to expand.

Let"s discuss video input interfaces, starting with the D-Terminal and component video standards. The video signals themselves are identical for both of these. The video signal is composed of the following three signal types: the Y brightness/synchronization signal; the Pb (Cb) signal for the difference between blue and Y; and the Pr (Cr) signal carrying the difference between red and Y. Altogether, these are referred to as a component video signal. A characteristic of this technology is its ability to input and output high-quality analog video signals by omitting the process of video-signal separation and combination.

A component video port has separate connectors for each of the three video-signal types: A green connector for the Y signal, a blue connector for the Pb (Cb) signal, and a red connector for the Pr (Cr) signal. In most cases, the compatible video formats are 480i, 480p, 720p, and 1080i, with connectors labeled Y, Cb, and Cr compatible with 480i video and connectors labeled Y, Pb, and Pr with higher-quality video formats.

While component video ports offer higher quality and greater benefits than most other types of analog video input, they also entail inconveniences, including more troublesome connections (since they use three connectors) and greater space requirements on devices equipped with such ports. Additionally, they are incapable of transmitting control signals. In Japan, the D-Terminal standard, formulated by the Japan Electronics and Information Technology Industries Association (JEITA, known at the time as the Electronic Industry Association of Japan, or EIAJ), which features its own improvements on these points, has entered widespread use.

A D-Terminal connector combines the three types of component video signals into a single cable and is easier to connect. It also embeds a control signal to identify scanning lines, scanning method, and aspect ratio. (In passing, it"s called a D-Terminal only because its connector is shaped like the letter "D"; the "D" does not mean "digital." Signals flowing through the D-Terminal and the connecting cable are analog.) The table below gives the types of D-Terminals (D1 – 5) and corresponding video formats. While many products feature D5 terminals, which are compatible with 1080p video, this is not specified in the official JEITA standard.

Let"s consider S-Video and composite video ports. Video consists of a brightness signal and a color signal, combined to create a composite video signal. A composite video port transmits the composite video signal as is; an S-Video port transmits the composite signal separated into a brightness signal and a color signal. Since less processing is needed to combine and separate the brightness and color signals, an S-Video port provides higher picture quality than a composite video port.

On an RCA connector with three single pins in a row, the yellow pin is the composite female connector (photo at left). Most composite cables assume the form of a single cable that splits into three connectors, with the yellow connector used for video and the red and white for stereo audio (center photo). An S-Video female connector (photo at right), which has four pins.

Additionally, there are two types of S-Video ports: S1, which can identify video with aspect ratios of 4:3 and 16:9; and S2, which can identify "letterbox" video with black bands above and below, to display 16:9 aspect-ratio video on 4:3 aspect-ratio monitors. A display device receiving video with a 16:9 aspect ratio or letterbox video performs the appropriate scaling to display the correct aspect ratio.

S-Video and composite ports are capable of handling video up to standard-definition NTSC (480i). They are likely to be phased out gradually in the future, except for applications requiring the connection of older video equipment such as VHS video decks or DV cameras.

Let"s conclude by returning to the subject of PC environments. Some recent products use USB ports for PC display output. While USB was not originally intended as a display interface, demand has emerged for an easier way (easier than using a D-Sub cable) to set up multi-monitor environments, particularly for laptops and low-priced netbooks.

Most such products are adapters, which connect to the PC using USB and feature DVI-D or DVI-I connectors on the output side. These are then connected to LCD monitors. After the user installs a device driver, the PC recognizes the adapter as a monitor adapter. Users can create a multi-monitor environment in Windows by activating the secondary monitor connected to the adapter in Display Properties. In terms of display performance, these adapters are not well suited to uses that require high-speed response; they are associated with slight delays in reflecting mouse or keyboard operations.

A small number of LCD monitors on the market use USB as a video input interface, making it possible to output and display a PC screen through a USB connection between the PC and the LCD display. These, too, are ideal for laptops and netbooks, since they allow users to use laptops connected to large-screen LCD monitors at their office desks or at home, then use the laptops for mobile use when out and about simply by unplugging a single USB cable.
