lcd touch screen for raspberry pi free sample

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?

Ideal for entertainment, as a satnav, monitoring your car"s performance via the OBD-II interface, and even for reverse parking, a carputer can considerably improve your driving experience. Often, though, the focus is on entertainment.

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.

This is one of those projects where the electronics and the UI are straightforward. It"s really the case that can pose problems, if you don"t own a 3D printer.

This is a new Pi Pico display from Waveshare with many more pixels. It is a 2inch LCD display module, designed for Raspberry Pi Pico, with an embedded ST7789VW driver, 65K RGB colours, 320x240 pixels and an SPI interface. A Pi Pico can be plugged into the rear of the screen for very easy connection without any soldering. It sports 4 simple button switches for user input. It is bright, colourful and easy to program. The makers supply an example program (see below), which includes the display driver, making it very easy to get started. The manufacturer"s wiki can be found at:

Obviously 480x320 is going to look like crap on your main monitor, and is unworkable, and 1920x1080 is not even going to be visible on this small screen.

Raspberry Pi OS provides touchscreen drivers with support for ten-finger touch and an on-screen keyboard, giving you full functionality without the need to connect a keyboard or mouse.

The 800 x 480 display connects to Raspberry Pi via an adapter board that handles power and signal conversion. Only two connections to your Raspberry Pi are required: power from the GPIO port, and a ribbon cable that connects to the DSI port on all Raspberry Pi computers except for the Raspberry Pi Zero line.

There are several of these great touchscreens around our home that show everyday information, control the surroundings, and take care of some repetitive tasks.

The system is composed of lightweight message-enabled software modules which run independently on your main touchscreen Raspberry Pi, or other Pi boards around the home. The modules communicate with each other by exchanging Mosquitto messages and responding accordingly. In fact, each of the screen labels shows data from its associated message, and each of the buttons and events transmits a message or set of messages. We can configure them to our heart’s desire. Here’s some of what we have set up:

Critically, for privacy, none of your data or activities is sent anywhere on the internet, with just some simple calls to APIs for weather, air quality, etc. It’s completely under your control. The open-source nature of the system gives you complete transparency – no black boxes here.

To start setting up the system, you need to install the Kivy Pie build – this is an image of Raspbian Jessie with Kivy already installed and ready to go. Kivy is a cross-platform library that allows you to program the touchscreen to your heart’s content!

You’ll then need to install the Apache web server and PHP. Apache serves up the webpages for remote control and configuration. PHP is used to drive interactive webpages which store information to the database and transmit commands using Mosquitto:

Now we can customise the screens to our needs. We do this from the webpages, selecting which messages to associate with which screen labels, which text for the buttons, and whether they are toggle (two-state buttons – for lights and such) or simple buttons (single-state for alarm off and such).

Once we have done this, we can then assign messages to the buttons and events. Make sure not to forget to go to the configuration screen and set up your own custom settings for emails and IP address for our Mosquitto communications along with some other goodies.

For each of the labels, select the message that you want to display. For the buttons, enter the text you want to appear on each button and the type of button (single/two-state) and save.

Now, for the actions, assign the list of messages to trigger. This is how we set up the button’s scheduled events and what to trigger on high/low sensor events.

Under Mosquitto communications, set the Broker address to match your Raspberry Pi’s IP address, and make sure the port matches your setup (in reality we can probably leave this port as set).

Next, we should check that the launcher.py Python script suits our requirements. On the Raspberry Pi, navigate to /home/sysop/Glance and open the launcher.py file:

MyApp is responsible for creating the screen class, MainScreen, and also holds application-level variables and contains the Mosquitto code for communications. MainScreen sets up the labels, buttons and icons, and callback methods for updating the screen.

As mentioned previously, the system is scalable, flexible, and extendable with the modules following a standard template. Each module has a specific purpose, whether gathering data from the internet, the sensors, or controlling something cool! Using HelloWorld.py as an example, you can then easily adapt it for other data sources, actions, and interfacing with other systems.

The ‘on-message’ callback method we assigned earlier will receive messages and is responsible for processing them. In this example, we check the host and the message to be sure it is the message that we are waiting for, and then just store the received value (extracted from the third part of the message)

We use the ‘Publish’ loop in this example to simply to send the data onto the Mosquitto network, periodically. Other modules will periodically poll the internet for data and share on the Mosquitto network, or trigger a send on change of GPIO state, etc.

When we click one of these buttons, Mosquitto messages are sent from the PHP behind the control webpage according to the command sequence we configured. These messages are then intercepted by the relevant Python module which, in turn, triggers the code to be executed perform the action; e.g. switch the I/O on the Raspberry Pi.

The database contains the settings and message definitions for the system. Most of the settings are configurable from the webpages; e.g. Mosquitto broker IP address.

The database also holds configurations for the screen layout, messages associated with screen labels and buttons, message sequences (i.e. the ‘macros’), and event schedules

One point to note is that all the messages used in the system are listed in the messages table. The host must match the host name of the Raspberry Pi to which they are associated.

It would be remiss of us not to include what you can do in terms of sensors. We put together a collection of some of our favourite sensors, a buzzer, a PIR motion sensor, and created a PCB to connect them all, for convenience mainly.

The I2C bus is neat, just requiring two connections for communications (plus power) and bundling these sensors up with motion detection and the buzzer. Using something like a PCF8574 I2C to I/O chip, you can interface the buzzer and PIR to the I2C, and expand the I/O at the same time. Alternatively, you can connect them directly to the GPIO using the the

We hope you find this system as useful and fun as we did and join the party to continue to evolve it, should you wish. These touchscreens are great little units and with the Raspberry Pi, internet, sensors, and data, the possibilities are endless.

systemd is the preferred method of starting applications on startup, but it is also one of the most complicated to use. With systemd, you have the benefit of being able to tell Linux to start certain programs only after certain services have started. As a result, it is a very robust tool for initializing your scripts and applications.

systemd is a relatively new suite of tools in the Linux world, and one of its intended purposes is to manage system processes after booting. When it was first released, systemd was meant to replace the init.d tool for starting programs. As of 2015, most of the major distributions include systemd, and since many kept init.d around for legacy support, you have the option of using either one. Be aware, however, that init.d may be deprecated, so systemd seems to be the future (for now).

A unit file is a plain text file that gives information to systemd about a service, device, mount point, etc. We"ll create a unit file that starts our program as a service (a process that runs in the background). Below are two examples of unit files: the first runs the blink.py example before the graphical desktop loads (useful for headless environments), and the second runs the clock.py example after the graphical desktop loads (useful if you are making a dashboard or GUI).

Feel free to change the Description as desired. The After key denotes when our program should run. multi-user.target is the system state where control is given over to the user (a "multi-user shell") but before the X Windows System is started. That means our program will run even without logging in! You can change this, depending on which services you need active before running your program (for example, network.target if you need networking). See here for a listing of all targets.

If your program requires graphical components (as in our clock.py example), then the following template is recommended for creating a systemd service.

Under [Service], we specify some environment variables. We want to connect to our primary display (this assumes only one display is connected to our Pi), so we set DISPLAY to :0, and we tell our application where to find the necessary credentials to use the X windows system with XAUTHORITY. ExecStart is the command we want to run (starting our Python clock program, in this case).

Unfortunately with systemd, we cannot tell exactly when the X system will start, and we cannot necessarily guarantee that a user will be logged in (unless you have enabled auto-login with sudo raspi-config). To account for this, we will brute force our program to restart (with Restart) every 10 seconds (with RestartSec) if it fails or exits. KillMode tells systemd to kill off any processes associated with our program if the service fails (or exits), and TimeoutSec=infinity means that we don"t ever want to stop trying to execute our program.

This starts a new bash shell, runs your program, and redirects the output (stdout) to a new clock.log text file. The 2>&1 command says that any errors (stderr) should also be redirected (written to) the same log file. Any output (e.g. from Python print() commands) or errors will then be saved to clock.log. You can view the log with the following command (note that you might need to stop the service and program before viewing the log):

Because your systemd unit file will likely run before .bashrc can alias the command python to Python 3, you might need to explicitly call the python3 command. To do that, just make sure that your call to Python is an absolute file location, for example, /usr/bin/python3.

For some services, like our clock.service example, you will need to stop the service before stopping the program. That"s because even if you stop the program (e.g. our Python GUI clock), the service will simply restart it 10 seconds later! To stop a service, enter the following command:

Note that stopping the service should send a stop command (SIGTERM--terminate signal) to your program. In most cases, this should stop the service and your program. If your program does not stop, see below on stopping your program.

ps -ax tells Linux to list out all the currently processes. We send that output to grep, which allows us to search for the keyword "python" (feel free to change it to the name of your program). Find the process ID (PID) number to the left of the listed process, and use the kill command to terminate that process:
