Rather than plug your Raspberry Pi into a TV, or connect via SSH (or remote desktop connections via VNC or RDP), you might have opted to purchase a Raspberry Pi touchscreen display.

Straightforward to set up, the touchscreen display has so many possibilities. But if you"ve left yours gathering dust in a drawer, there"s no way you"re going to experience the full benefits of such a useful piece of kit.

The alternative is to get it out of the drawer, hook your touchscreen display to your Raspberry Pi, and reformat the microSD card. It"s time to work on a new project -- one of these ideas should pique your interest.

Let"s start with perhaps the most obvious option. The official Raspberry Pi touchscreen display is seven inches diagonal, making it an ideal size for a photo frame. For the best results, you"ll need a wireless connection (Ethernet cables look unsightly on a mantelpiece) as well as a Raspberry Pi-compatible battery pack.

Several options are available to create a Raspberry Pi photo frame, mostly using Python code. You might opt to script your own, pulling images from a pre-populated directory. Alternatively, take a look at our guide to making your own photo frame with beautiful images and inspiring quotes. It pulls content from two Reddit channels -- images from /r/EarthPorn and quotes from /r/ShowerThoughts -- and mixes them together.

Rather than wait for the 24th century, why not bring the slick user interface found in Star Trek: The Next Generation to your Raspberry Pi today? While you won"t be able to drive a dilithium crystal powered warp drive with it, you can certainly control your smart home.

In the example above, Belkin WeMo switches and a Nest thermostat are manipulated via the Raspberry Pi, touchscreen display, and the InControlHA system with Wemo and Nest plugins. ST:TNG magic comes from an implementation of the Library Computer Access and Retrieval System (LCARS) seen in 1980s/1990s Star Trek. Coder Toby Kurien has developed an LCARS user interface for the Pi that has uses beyond home automation.

Building a carputer has long been the holy grail of technology DIYers, and the Raspberry Pi makes it far more achievable than ever before. But for the carputer to really take shape, it needs a display -- and what better than a touchscreen interface?

Setting up a Raspberry Pi carputer also requires a user interface, suitable power supply, as well as working connections to any additional hardware you employ. (This might include a mobile dongle and GPS for satnav, for instance.)

Now here is a unique use for the Pi and its touchscreen display. A compact, bench-based tool for controlling hardware on your bench (or kitchen or desk), this is a build with several purposes. It"s designed to help you get your home automation projects off the ground, but also includes support for a webcam to help you record your progress.

The idea here is simple. With just a Raspberry Pi, a webcam, and a touchscreen display -- plus a thermal printer -- you can build a versatile photo booth!

Projects along these lines can also benefit from better use of the touchscreen. Perhaps you could improve on this, and introduce some interesting photo effects that can be tweaked via the touchscreen prior to printing?

How about a smart mirror for your Raspberry Pi touchscreen display project? This is basically a mirror that not only shows your reflection, but also useful information. For instance, latest news and weather updates.

Naturally, a larger display would deliver the best results, but if you"re looking to get started with a smart mirror project, or develop your own from scratch, a Raspberry Pi combined with a touchscreen display is an excellent place to start.

Many existing projects are underway, and we took the time to compile six of them into a single list for your perusal. Use this as inspiration, a starting point, or just use someone else"s code to build your own information-serving smart mirror.

Want to pump some banging "toons" out of your Raspberry Pi? We"ve looked at some internet radio projects in the past, but adding in a touchscreen display changes things considerably. For a start, it"s a lot easier to find the station you want to listen to!

This example uses a much smaller Adafruit touchscreen display for the Raspberry Pi. You can get suitable results from any compatible touchscreen, however.

Alternatively, you might prefer the option to integrate your Raspberry Pi with your home audio setup. The build outlined below uses RuneAudio, a Bluetooth speaker, and your preferred audio HAT or shield.

Requiring the ProtoCentral HealthyPi HAT (a HAT is an expansion board for the Raspberry Pi) and the Windows-only Atmel software, this project results in a portable device to measure yours (or a patient"s) health.

With probes and electrodes attached, you"ll be able to observe and record thanks to visualization software on the Pi. Whether this is a system that can be adopted by the medical profession remains to be seen. We suspect it could turn out to be very useful in developing nations, or in the heart of infectious outbreaks.

We were impressed by this project over at Hackster.io, but note that there are many alternatives. Often these rely on compact LCD displays rather than the touchscreen solution.

Many home automation systems have been developed for, or ported to, the Raspberry Pi -- enough for their own list. Not all of these feature a touchscreen display, however.

One that does is the Makezine project below, that hooks up a Raspberry Pi running OpenHAB, an open source home automation system that can interface with hundreds of smart home products. Our own guide shows how you can use it to control some smart lighting. OpenHAB comes with several user interfaces. However, if they"re not your cup of tea, an LCARS UI theme is available.

Another great build, and the one we"re finishing on, is a Raspberry Pi-powered tablet computer. The idea is simple: place the Pi, the touchscreen display, and a rechargeable battery pack into a suitable case (more than likely 3D printed). You might opt to change the operating system; Raspbian Jessie with PIXEL (nor the previous desktop) isn"t really suitable as a touch-friendly interface. Happily, there are versions of Android available for the Raspberry Pi.

Looking for a display solution for a Raspberry PI? Crystalfontz has displays specifically designed for use with Raspberry PI"s in many sizes and touchscreen options. Whether you"re looking for a small 5" resistive touchscreen TFT or a 10.1" HDMI display; we"ve got you covered. These displays are a turnkey solution, simply plug them in with our accessory connectors and you"re ready to go.

This repository contains all the code for interfacing with a 16x2 character I2C liquid-crystal display (LCD). This accompanies my Youtube tutorial: Raspberry Pi - Mini LCD Display Tutorial.

During the installation, pay attention to any messages about python and python3 usage, as they inform which version you should use to interface with the LCD driver. For example:

It is possible to define in CG RAM memory up to 8 custom characters. These characters can be prompted on LCD the same way as any characters from the characters table. Codes for the custom characters are unique and as follows:

This demo uses ping and nc (netcat) to monitor the network status of hosts and services, respectively. Hosts and services can be modified by editing their respective dictionaries:

exchangerate-api.com / free.currencyconverterapi.com: There are a lot of currency apis but these ones offer free currency exchange info. Both are used, one as main, the other as backup. Requires an API key to use.

In order to use the script, you need to get API key tokens for both exchange rate services and the weather api. Once you"ve done that, edit the script to put your tokens in the USER VARIABLES section.

Adding a small LCD touchscreen to Raspberry Pi seems like a terrific idea (see the "Choosing a Touchscreen" box) – until you realize that the default desktop environment is not optimized for tiny displays. The tendency of programmers to design for an old-style computer desktop means launching applications and performing actions on a tiny touchscreen is often fiddly at best. In most cases, though, you might just be using the touchscreen for a few specific tasks, and building your own graphical interface might seem like too much trouble.

Several LCD touchscreens for Raspberry Pi are available on the market. The PiTFT 2.8-inch 320x240 panel from Adafruit [3] is available through several web stores. You can also buy a stylish PiTFT Pibow case [4] for it. You"ll find a wealth of documentation on installing and using PiTFT on Adafruit"s website [5]. RPI-Display from Watterott [6] is another good option – especially if you are based in Europe. Watterott also sells an enclosure for the Raspberry Pi and RPI-Display combo [7], and all the required software (including an SD card image) is available in the RPi-Display GitHub repository [8]. It"s also possible to find a decent touchscreen for Raspberry Pi on eBay, but make sure it comes with the required software.

Enter PiMenu [1] – a simple solution written in Python and TkInter that lets you build tile-based graphical interfaces with consummate ease. PiMenu was originally designed by Andreas Gohr of DokuWiki fame for his paper backup project [2]. Thanks to its simplicity and versatility, however, PiMenu can be easily adapted for any other project requiring a simple graphical interface.

command to make PiMenu work on Raspberry Pi. Then, grab the latest release of PiMenu as a ZIP archive from the project"s GitHub repository, or clone the repository using

PiMenu consists of three key parts: the pimenu.py Python script that draws the GUI, the pimenu.yaml configuration file that defines menu items, and the pimenu.sh Bash shell script that performs actions based on arguments received from pimenu.py.

For each menu item specified in the pimenu.yaml configuration file, PiMenu draws a tile, and the main script automatically resizes tiles to fit them in the window. The tiled interface is inspired by the Windows 8 design, which actually works pretty well on Raspberry Pi. In the pimenu.yaml file, you can specify a hierarchy of menu items, so you can create a rather elaborate menu structure.

I don"t travel as much as I would like to, but when I do, I take a lot of photos. And I always wanted to build a Raspberry Pi-based backup device to keep my precious snapshots safe while I"m traveling. PiMenu was the missing piece required to bring this idea to fruition. Ideally, the Raspberry Pi-based backup box should perform several tasks, such as transferring photos directly from a camera or a card reader and backing up the transferred photos to a USB storage device.

The first order of business is to edit the pimenu.yaml file to include the required menu items (Listing 1). Each menu item in the configuration file has four properties: mandatory name and label as well as optional color and icon. The icon refers to the name of the appropriate icon in the GIF format stored in the ico directory (e.g., icon: "menu" points to the ico/menu.gif graphics file).

The pimenu.py Python script not only draws the interface using the configuration from the pimenu.yaml file, but it also reads the names of the menu tiles when pressed and executes the pimenu.sh Bash shell script. This is where all the action happens. You can configure the script to perform actions based on the name of the pressed tile. One way is to configure the script to read the name of the pressed tile and then use a case conditional statement to perform the desired actions.

To obtain the name of the pressed tile, you can use the echo "$*" command. However, this command returns the names of all menu items if the pressed tile resides somewhere down the menu hierarchy. For example, if you press the Backup tile, the returned result will be Menu Backup. Because pimenu.sh needs only the name of the pressed tile, you can use the awk tool to extract it from the result returned by the echo "$*" command and assign the obtained value to the key variable:

to obtain the mountpoint of the USB device. It does so by using the find tool, which looks for non-empty folders in the media directory. The sed tool in turn applies proper escaping if the obtained path contains white spaces (e.g., /media/NIKON D90/DCIM/100NCD90/ becomes /media/NIKON\ D90/DCIM/100NCD90/). This command assumes that there is only one USB storage device or card reader connected to Raspberry Pi at the time.

To back up the transferred photos to an external storage device connected to the USB port of Raspberry Pi, the script features two commands: The first one obtains the mountpoint of the USB device, and the second command uses the rsync tool to copy the photos.

Tapping on the tile with no sub-tiles returns an empty result, so the final part of the case statement closes PiMenu by killing all running pimenu processes if the $key value is empty – that is, the "") condition.

With PiMenu configured and ready to go, you have only two things left to do: Install the required packages and provide a way to launch PiMenu without using the keyboard. To install the packages, run the following commands:

With minimal tweaking, you can improve the described project and put it to other uses. For example, you can easily extend PiMenu"s configuration to include cloud backup (e.g., using rsync via SSH), preview photos downloaded from the camera or a card reader, and much more. You can easily modify the project to use Raspberry Pi as a backup device not only for photos but also for files and documents in general.

You can also adapt PiMenu to entirely different uses altogether. For example, you can turn your Raspberry Pi into an Internet radio device that lets you choose stations via the touch-screen menu, or you can build a simple launcher that opens specific applications. In other words, if you have a Raspberry Pi with an LCD touchscreen, PiMenu can prove to be an indispensable ingredient for making the combo useful.

That’s right! In today’s tutorial I show you how to wire up and program your very own mini LCD display to your Raspberry Pi! By the end the of this video you will be printing your own messages to your very own screen module and will understand all of the Python code behind it. A good, cheap and enjoyable little project for Raspberry Pi – with plenty of scope for your own further developments!

In the previous article, I described the steps needed to install an LCD touchscreen on the Raspberry Pi. In this article, I will show you how to adjust the screen rotation of the LCD to landscape mode, and will show you how to calibrate the touchscreen pointer for optimal accuracy. Just follow the steps below to compete the process of setting up your Raspberry Pi LCD touchscreen:

1. First we need to change the setting for screen rotation in the /boot/cmdline.txt file. This setting is called fbtft_device.rotate=X. By default, this is set to X=0, which results in a portrait mode screen orientation. In order to switch the orientation to landscape mode, change fbtft_device.rotate=0 to fbtft_device.rotate=90. Enter sudo nano /boot/cmdline.txt at the command prompt. There should only be one line in this file. Go to the end of it and you will find the fbtft_device.rotate=X setting. Change the value from 0 to 90:

However, if you try to touch the screen now, you will find that the pointer movement does not correspond to your finger movement. This is because the LCD screen driver and the touchscreen controller driver have separate settings for screen rotation. We need to change the rotation of the touchscreen controller driver to match the rotation of the LCD screen driver.

2. You probably noticed that dragging your finger to the right moves the pointer up, not to the right. This indicates that the x and y axes of the touchscreen are swapped. To correct this, we need to swap the x axis for the y axis. This can be done by changing the swap_xy=X parameter in /etc/modules.

Now if you drag your finger around the screen, you will notice that the y axis (up and down) is correctly aligned with the motion of your finger. However, the x axis (left and right) is still inverted. To fix this, we need to install two more kernel modules, xinput and evtest. xinput is a Linux utility that will allow us to configure input device settings for the touchscreen controller, and evtest is an input device event monitor and query tool.

After the Pi finishes rebooting, you should notice that when you move your finger across the touch screen, the pointer should follow correctly in both axes. If you are using the Raspberry Pi 2 Model B, you will need to complete the calibration steps below before the pointer follows your finger correctly (and make sure that you have enabled startx to load automatically – see step 6 in this article).

You can rotate the screen 90 degrees (as we did in this tutorial) and the power connector will be at the bottom of the screen, but you can also rotate it 270 degrees so that the power connector is at the top of the screen. To do this, simply enter fbtft_device.rotate=270 in the /boot/cmdline.txt file. Then change the DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 0 1 line in the /etc/X11/xinit/xinitrc file to DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 1 0. All you need to do is switch the values of the 0 and 1 at the end of this line.

Now that we have our LCD touchscreen up and running, the final step in the installation is the calibration of touch control. This will make the pointer much more accurate and easier to use.

2. Now we need to install the calibration tool we will be using, xinput_calibrator; and other filters for controlling the touchscreen response. Install the tslib library by entering aptitude install libts-bin:

4. Now we can use ts_calibrate. Enter ts_calibrate at the command prompt (make sure you are still in root mode) to run the ts_calibrate program. The program will consecutively display five crosses on different parts of the screen, which you need to touch with as much precision as possible:

Drag the cross around the screen and observe how closely it follows your finger or stylus to test the accuracy of the calibration. Now press the “Draw” button to enter the drawing mode:

This is kind of a long process, but it is well worth it if you want to get the LCD touchscreen set up properly. So if you have any trouble setting this up or have anything to say, please leave a comment below. Also, if you found this article useful, please share it with your friends!
